Silicone sealant belongs to the group of polymers and is designed for high-quality adhesion different surfaces... (Fig. 1) This is a leader in its segment, whose specifications are many times superior to analogs. The seams in the window and doorways, fix glass in frames, glue plexiglass, aluminum, ceramic structures, polycarbonate, seal the roof, drainpipes, etc.

Factors influencing hardening

Silicone sealant, the drying time of which depends on the thickness, depth of the layer and the density of the structure, is applied to the surface in the form of a thick sticky mass. (Fig. 2) After 5 to 15 minutes, a thin protective film forms on it. The hardening rate is determined by 4 factors:

- temperature;

- humidity;

- the presence of additives added to the composition at the production stage.

The main factor affecting the drying time of silicone sealant is temperature environment... Increasing it by 5 degrees speeds up the polymerization process by 2 times. However, there is no direct relationship here, since education protective film is a deterrent. If you put silicone sealant into the drying cabinet, it will not harden at all, since there is too little moisture in it. It makes no sense to raise the temperature over 50 °, it is better to increase the humidity.

The curing time directly depends on the amount of fillers (mechanical and organic substances, fungicides, dyes) and the more, the worse. In addition, shrinkage after hardening can reach 30%, while pure silicone has a small indicator. (2-4%).

The silicone sealant hardens during polymerization during the evaporation of the expelled component. The presence of moisture influences the result depending on the type of product (acidic, neutral or acrylic).

Silicone sealant, which usually has a drying time of 24 to 48 hours, allows it to be quickly put into operation. A technical data sheet is issued for each silicone system, in which this figure is specified. Physical properties the suture is fully formed in 6-14 days.

The main factor affecting the drying time of silicone sealant is the ambient temperature. Increasing it by 5 degrees accelerates the polymerization process by 2 times.

Drying time of different types of sealants

When wondering how long a silicone sealant dries, you should pay special attention to it. chemical composition... Such mixtures can be acidic as well as neutral. In the first case, the product has a lower cost, but it is unsuitable for application to metal, as it can cause corrosion damage. As an exception, unadded aluminum and stainless steel are used. But for other materials such as ceramics, polycarbonate, glass and wood, these sealants are excellent. It will give off a vinegar smell when used and will dry out over a period of 4 to 6 hours.

Drying of neutral compounds

How long does silicone sealant dry? Masters often try to solve this question. If you asked yourself about it, you should familiarize yourself in more detail with its composition. The mixture can be neutral and can be applied to almost any surface. Such products are distinguished by excellent performance characteristics but it comes with a high price tag. After it is possible to apply such a sealant, it will dry within a day, and the ambient temperature should be equal to +5 to +40 ° С.

General drying time of the sealant

The drying time of the silicone sealant will also depend on other circumstances, such as the type of humidity, as well as the area of ​​application. The surface, until it comes off, will set in 20 minutes. But complete hardening should be expected only after the expiration of the day. In this case, the average speed will be 2 mm every 24 hours. When it comes to hot conditions, the drying time of the sealant can be calculated. To do this, the average curing time is multiplied by a factor of 1.5.

It is important to pay attention to the average curing time of the sealant, which is promised by the manufacturer, before making calculations. In this case, normal conditions must be observed. Depending on the area of ​​use, sealants can be divided into three types: for indoor, outdoor work and work in rooms where there is a high level of humidity. The components that make up the sealant and that affect the speed of its drying are also different. How long the silicone sealant dries is indicated by the manufacturer, but you should take into account that this period can be completed by the composition detaching from the surface, if the latter is not properly prepared. It must be degreased, washed and dried well.

Drying time for aquarium sealant

How much silicone sealant dries for an aquarium, fish lovers are often interested. If you are, then you can take into account the above recommendations. However, one can also consider specific example: PENOSIL Premium Aquarium Siliconet is a sealant that can be used at ambient temperatures from +5 to +40 ° C. This composition can be operated in a wide range from -40 to +100 ° С. The drying time of its surface will not exceed 15 minutes, and the maximum elongation is 250%.

Drying time of Moment sealant and instructions for its use

How long does Moment silicone sealant dry? This question is highlighted by the manufacturer. Its complete hardening should be expected after a maximum of 4 days, while the minimum drying time lasts for 2 days. Before use this composition The seam must be cleaned and degreased, and adhesive tape must be glued around the edges to ensure neat operation. The cap is unscrewed, the membrane is pierced and the nozzle is attached. The tip should be trimmed to obtain a seal before required diameter.

The sealant is squeezed into the joint with a wrench and leveled with a spatula or damp finger. The next step is to get rid of the tape. After you find out how long the silicone sealant dries, you can start sealing the windows, for this you need to open the frame, apply the composition around the perimeter of the window box, excluding the gluing of the frames. For this, the sealant is covered with a film or foil. The window should be left closed so that the composition fills the required volume as much as possible. When the mixture hardens, the film can be removed.

Reviews of the Moment brand sanitary sealant

Before purchasing, consumers ask themselves how long the Moment sanitary silicone sealant dries. In the case of this composition, you can follow the recommendations from the manufacturer. The film will form within 15 minutes if relative humidity ambient air will be 50%. Whereas the ambient temperature should be 23 ° C. This composition will harden in a day if its thickness is 2 mm. This curing rate is to be expected under the mentioned conditions.

It is not recommended to use the mixture on surfaces that have been subject to corrosion, as well as on cement, plaster and concrete foundations... Do not apply sealant to mirror substrates, natural stone or aquariums. It is intended for sealing surfaces in bathrooms and kitchens, baths, and showers. The mixture is versatile, as it can be used both outside and inside buildings.

Conclusion

Now you know how much silicone sealant dries for the bathroom and other premises. These formulations are the leaders in the world of goods for this purpose. They are resistant to aggressive environmental influences and are able to undergo ultraviolet radiation and sudden changes in temperature. Silicone sealants do not provide for the treatment of the glued surfaces with a primer, the adhesion is so high that the mixture is capable of taking even very impressive deformations. Sharp displacements and turns are not terrible for a filled seam, since the fibers of the composition are capable of lengthening, sometimes up to 900%. These qualities can be called truly outstanding, since they allow us to solve the existing problem of the susceptibility of products and structures. different kinds factors.

Types of silicone based sealants

There are two types of silicone sealants: neutral and acidic. Neutral (also called sanitary) - resistant to high temperatures, so it is more often used to repair pipes heating system, v plumbing works ah, when renovating the kitchen and bathroom. It contains alcohol and ketoxime, which give it antifungal properties.

Acidic sealants also contain antifungal agents. This is often acetic acid. the main problem acid sealants in that they cannot be used on metal, marble and cement-containing surfaces. But he sticks together wood, plastic and ceramics perfectly. When hit on wooden surfaces, such a substance gets deep into the material and creates additional protection for it.

Where is the sealant used?

Silicone sealants are quite suitable for both indoor and outdoor use. He is especially good at installing plumbing. In addition, silicone is often used in the assembly of various metal and plastic parts, in mechanical engineering and machine tool construction.

At a construction site and repair activities, silicone sealant is useful in such cases:

• For sealing gaps and joints when installing doors and windows.


• When gluing stone and ceramic tiles.
• In all plumbing installation works... In the bathroom, it will serve to process seams at the points of connection of plumbing, in attaching mirrors, during work with water supply and sewerage pipes, to seal the seams between the bathroom and the wall. It is also used to seal various cracks and joints in shower cabins. Since the sealant makes it impossible for moisture to penetrate, all kinds of fungi will not appear.
• During installation work with the roof, all seams are treated with a sealant.
• When installing electrical wiring.

How long does the composition dry?

Gradually we came to the main question: how long does silicone sealant dry? Its hardening period is highly dependent on the field of application and the composition of the product itself.

The polymerization time of the sealant, depending on the type:

• The acid based sealant takes about 4-6 hours to dry.
• The neutral silicone sealant will take longer to dry completely, about 24 hours. Besides, important condition is a plus temperature - from 5 to 40 degrees.

Depending on the area of ​​use, the drying time of the sealant can be as follows:

• If you apply this material generously enough, then its outer layer hardens and does not stick to your hands after 15 minutes. And in the inner layers at this time, the polymerization process is just starting. It passes at such a speed: every 2 mm of the inner layer hardens in 24 hours.
• If the room temperature rises significantly, the sealant will dry twice as fast. And if you carry out outdoor work in the cold season, then the sealant should be given more time to dry.

Tip: Read what is written on the package. Usually they indicate the drying time of the sealant under certain conditions.

Bathroom sealant

How long does the sealant dry in high humidity conditions in the bathroom? Again, this depends on the choice of the product itself:

Important: Do not lay several strips of sealant in one place, otherwise the whole point of this procedure will be lost and no sealing will occur, because the layers will peel off from each other. Apply a strip of the desired thickness immediately, simply pushing harder on the trigger.

Speed ​​up the drying of the sealant

Now you already know how long neutral and acidic silicone bath sealant dries. But in some cases, I would like to speed up the process somewhat. It is possible to do it like this:

• By raising the air temperature in the room to 40 degrees.

• By opening all windows and doors to create maximum ventilation.

• Spraying already sealed joints with water from a sprayer. Moisture on the surface of the sealant will accelerate the curing process.

Inspect the sealant cartridge carefully upon purchase. Make sure it is complete and also read the composition. The more there are various additives, the less elastic the sealant will be. The price will also tell a lot about the product. High-quality sealant, from good manufacturer costs more.

okanalizacii.ru

How to speed up the drying time of the sealant

There are situations when renovation work, for various reasons, you need to speed up, and as a result, speed up the drying time of the silicone sealant. The following are basic ways to help your sealant dry faster.

1. The higher the temperature, the faster the reaction goes. But do not go to extremes and do not try to help the material with a hairdryer or other "thermal" device. direct action... If you exceed the temperature specified by the manufacturer, your sealant will most likely completely collapse.
2. The polymerization reaction is accelerated by two factors: air and moisture contained in it. Therefore, it is necessary to increase the air flow, i.e. create a simple draft;
3. Spray the sealant with water from a spray bottle or hold over steam. But in no case do not pour or lower parts under water;
4. Increase the room temperature. Boundary figure +40. The most convenient way to do this is with a stretch ceiling heat gun.

Drying time of the sealant, depending on the composition

If you are also interested in the question of how much silicone sealant dries, then it is important to pay attention to the composition of the mixture. On this basis, sealants can be classified into acidic and neutral. The former are characterized by a low price, but they cannot be used for application to metal, as they cause corrosion damage. But the application can be carried out on unadded aluminum and stainless steel, but for other materials such as ceramics, glass, wood and polycarbonate, an acidic sealant is perfectly suitable.

It gives off a vinegar smell when used and dries in 4 to 6 hours. If you are faced with the question of how much silicone sealant dries, then it is important to pay attention also to neutral compounds. They can be used with almost any material. The disadvantage of such mixtures is their high cost. After application, the silicone sealant with a neutral composition will dry out within 24 hours, while the temperature should be kept at a level of +5 to +40 ° C.

Drying time of the sealant depending on the area of ​​use

Many consumers today are interested in the question of how much silicone sealant dries. Usually, the surface of the sealant layer sets within 15 minutes, during which time the material stops sticking, but complete curing should be expected in a day, which is true for a 2 mm thick layer. If the environmental conditions are characterized by a high temperature, then the drying time can be determined by multiplying the polymerization period under normal conditions by a factor equal to the limit from 1.5 to 2.

Depending on the scope of use of the sealant, it can be classified into three types:

• for rooms with high humidity;
• for outdoor work;
• for interior work.

The composition of the material may contain ingredients that affect the drying rate. It should be remembered that in order to improve adhesion, the surface to be treated must be prepared, in this case you can count on the sealant to dry along with the base.

Features of drying sanitary sealant

Quite often, novice home craftsmen wonder how much silicone sealant dries for the bathroom. If you want the layer of material not to become covered with mold and fungus after a while, then you should choose a composition that contains fungicides. This is especially true for those mixtures that will be used in rooms with higher humidity than normal.

When sealing the joints between the wall and the bathroom with a sealant, the applied layer usually turns out to be quite voluminous. This indicates that the day will not be enough for complete polymerization. Even if the outer layer seems dry, there will still be liquid sealant.

For complete solidification, it is necessary to leave the layer without movement and stress for two days. If you are also concerned about the question of how long the silicone sealant dries, then you should remember that it is important to immediately make a layer of the desired thickness. Layer-by-layer application of sealant is not permitted.

What to do for faster drying of the sealant

To date, several methods are known that affect the acceleration of the polymerization process of silicone sealant. To do this, increase the temperature in the room to 40 ° C, make ventilation more intensive, and also sprinkle the already treated seams with water. In this case, you must use a spray. This fact is explained by the fact that moisture accelerates polymerization.

What else you need to know about the drying rate of the sealant

Experts know how long a silicone sealant needs to dry. They know that this is also influenced by the density of the mass. When it comes to an acidic sealant, it may take as little as 5 hours to completely dry, while a neutral agent dries much longer.

If you plan to work in the bathroom, then you should purchase a sanitary or universal product, but you should refuse to use acrylic sealant. When you have to finish a through joint, to which air is provided from the other side, you can guarantee more fast drying seam. Don't buy paper-wrapped silicone sealants or materials that are suspiciously cheap. This will negatively affect the quality of the work performed.

Partial solidification of the mixture can occur after 3 hours. This indicates that the layer will dry out only in places. But for more thin layers this period may be sufficient to complete the polymerization process. After this time, the strength of the seam will increase. Therefore, it is recommended to leave the material for a longer period. The above indicators can be attributed not to all sealants.

In some cases, it may take up to 4 weeks for the mixture to solidify completely. This applies to parquet compounds. If you are still wondering how much sanitary silicone sealant dries, then you should know that material of the same composition and purpose can dry in different ways if it is made by different manufacturers.

Drying rate of Moment brand sealant

Silicone sealant under the Moment brand has a transparent structure and costs the consumer 104 rubles. per packing. It is used for renovation and general construction work such as sealing glass doors and windows, walls and ceilings, building glass blocks, and ceramic tile surfaces.

The composition is characterized by high weather and heat resistance. The material hardens when exposed to air humidity. His specific gravity reaches 0.99 g / ml, while the application temperature can vary from +5 to +40 ° C. When using, the master will feel a specific light odor that will persist during the polymerization process, then it disappears. The extrusion speed reaches 320 g / min, but the tack-free layer will dry within 15 minutes, which is true for 23 ° C air temperature and 50% humidity.

The most important question that consumers ask when using the described composition is how long the Moment silicone sealant dries. After reading the instructions, you will be able to understand that a layer with a thickness of 2 mm will dry out in one day, these parameters are relevant for the environmental conditions described above. The thermal resistance of the mixture varies from -40 to +150 ° C.

Drying speed of silicone neutral sealant "Moment Herment"

This one-component, neutral, high-quality formulation is made on the basis of a silicone polymer. It is used for filling joints and seams, as well as for gluing surfaces that will be used outdoors or indoors. You may be interested in the question of how long the silicone glue-sealant dries.

V this case it can be argued that a 3 mm layer will dry in one day, while environmental conditions should be maintained at 23 ° C and 50% humidity. Under the same conditions, a film on the upper surface of which is formed in a time from 10 to 20 minutes. The temperature of use remains the same as in the above-described case, and varies from +5 to +40 ° C.

Conclusion

Silicone sealant is a construction mixture that is used to fill gaps in order to protect structures from external factors. This material is also used for gluing surfaces to each other.

Typically, the time for complete drying of the sealant is 24 hours and depends on the type of silicone, the density of its composition and production technology. Usually, the technology for using the sealant is indicated on the packaging, and all the manufacturer's recommendations must be strictly followed. After 20 minutes after covering with a sealant, a film appears on the seam, and after 2 hours, when probing the joint, it may seem that the sealant is completely dry. However, you can only feel the upper layers; the silicone inside the joint will still be damp. In this case, the premature use of water can nullify all your efforts, and the plumbing will start to leak again. Drying of the sealant directly depends on the thickness of the applied silicone layer per linear meter.

The thicker the silicone layer, the longer it takes to dry. There are the following guidelines to help speed up the process. So, how to quickly dry the sealant: For the drying process to be fast, the first step is to thoroughly prepare the surface before applying the sealant. Use a solvent to thoroughly clean the bonding areas of dust, dirt and other foreign matter.

After that, it is necessary to thoroughly dry the surface so that there are no water droplets on it. To do this, you can use a hair dryer, since with an ordinary rag you can contaminate the bonded areas again. Direct a hot jet of air directly to the areas where the sealant will be applied until the surface is completely dry. After you have thoroughly lubricated the surface areas with silicone, we proceed to the main question of how to dry the sealant. If it is not possible to withstand 24 hours, put an additional heater... In this case, complete drying should occur at least 2 times faster, and very soon you will be able to fully use water.

We want to give one more advice - when you buy a sealant, carefully read the instructions and try to buy quick-drying sealants. Also, it will not be superfluous to consult with the seller in the store. With extensive experience in sales, he can advise which sealant is best for you and give good advice about its application and drying. Usually, haste is required when gluing plumbing fixtures, since it is difficult to do without using water. When sealing roof joints, ceramic tiles or the glass of the aquarium, it is possible to wait, so in such a situation it is better not to rush and fully withstand the technology.

Good afternoon. How long does it take for the silicone sealant to dry completely in the bathroom?

To seal construction seams from moisture, insulate joints in the bathroom, one-component silicone sealants are most often used. Thanks to the well-thought-out shape of the package and the correct consistency, it is very convenient to work with them. Silicone adheres well and firmly to surfaces and does not allow moisture to pass through. The only thing to learn before starting work is how long the bath silicone sealant dries.

There are two types of silicone sealants: neutral and acidic. Neutral (also called sanitary) - resistant to high temperatures, so it is more often used to repair pipes of a heating system, in plumbing, during repairs in the kitchen and in the bathroom. It contains alcohol and ketoxime, which give it antifungal properties.

Acidic sealants also contain antifungal agents. This is often acetic acid. The main problem with acid sealants is that they cannot be used on metal, marble and cement-containing surfaces. But he sticks together wood, plastic and ceramics perfectly. When it gets on wooden surfaces, such a substance gets deep into the material and creates additional protection for it.

It is also used to seal various cracks and joints in shower cabins. Since the sealant makes it impossible for moisture to penetrate, all kinds of fungi will not appear.
• During installation work with the roof, all seams are treated with a sealant.
• When installing electrical wiring.

How long does the composition dry?

Gradually we came to the main question: how long does silicone sealant dry? Its hardening period is highly dependent on the field of application and the composition of the product itself.

The polymerization time of the sealant, depending on the type:

• The acid based sealant takes about 4-6 hours to dry.
• The neutral silicone sealant will take longer to dry completely, about 24 hours. In addition, an important condition is a positive temperature - from 5 to 40 degrees.

Depending on the area of ​​use, the drying time of the sealant can be as follows:

• If you apply this material generously enough, then its outer layer hardens and does not stick to your hands after 15 minutes. And in the inner layers at this time, the polymerization process is just starting. It passes at such a speed: every 2 mm of the inner layer hardens in 24 hours.
• If the room temperature rises significantly, the sealant will dry twice as fast. And if you carry out outdoor work in the cold season, then the sealant should be given more time to dry.

Tip: Read what is written on the package. Usually they indicate the drying time of the sealant under certain conditions.

Bathroom sealant

How long does the sealant dry in high humidity conditions in the bathroom? Again, this depends on the choice of the product itself:

Important: Do not lay several strips of sealant in one place, otherwise the whole point of this procedure will be lost and no sealing will occur, because the layers will peel off from each other. Apply a strip of the desired thickness immediately, simply pushing harder on the trigger.

Now you already know how long neutral and acidic silicone bath sealant dries. But in some cases, I would like to speed up the process somewhat. It is possible to do it like this:

• By raising the air temperature in the room to 40 degrees.

• By opening all windows and doors to create maximum ventilation.

• Spraying already sealed joints with water from a sprayer. Moisture on the surface of the sealant will accelerate the curing process.

Inspect the sealant cartridge carefully upon purchase. Make sure it is complete and also read the composition. The more there are various additives, the less elastic the sealant will be. The price will also tell a lot about the product. A quality sealant from a good manufacturer is more expensive.

Waterproofing is a mandatory procedure in a room where water is constantly used. Silicone sealant is popular and easy to use. Let's figure out how much silicone dries in the bathroom and how this is related to its type.

Acid and neutral type sealants

Silicone sealants are classified into two main types, each with different properties and different times drying:

1. Acid. Easily recognizable by the characteristic strong smell vinegar. Resistant to high temperatures and to ambient humidity. However, it reacts violently to the proximity of lime or other alkalis, so it cannot be used everywhere.
2. Neutral. They do not have any smell. More resistant to external active substances but poorly tolerated high humidity air.

And now we will consider both species in more detail, especially since they still have subspecies.

The most common type of acidic silicone sealant is sanitary, also called plumbing. Does not lend itself to harmful effects excess moisture as well as mold and mildew. Ideal for sealing crevices in the bathroom or kitchen. Adheres firmly to glass, enamel, ceramics, bricks, most types of metal.

Note! It is the sanitary sealant that is distinguished by the most fast time drying out.

Also, acidic silicone sealants are high-temperature (capable of withstanding up to 280 ° C), glass (well suited for porous or smooth surfaces, UV resistant) and versatile. From the name of the latter, it is clear that such a tool is suitable for almost any purpose. It is not recommended to use universal look only with acrylic, polyvinyl chloride and metals that corrode.

As for neutral sealants, they are divided into sanitary (good for sealing various building materials, but sensitive to moisture), bricklayers (prevent the occurrence of fungus), construction (powerfully attached to metal or gypsum) and more. rare species(for mirrors, for increased hygiene, aquarium, roofing).

How much each species dries

The drying time for acidic silicone sealant in the bathroom is from 4 to 6 hours, subject to all application rules (the surface is cleaned and degreased).

Complete drying of the neutral silicone sealant is achieved within 24 hours if the room temperature is above zero (but below +40 ° C).

In relation to the Moment glue-sealant, we can say that it begins to film in 15 minutes. So it is written in the instructions. Rejection with a thickness of 2 mm occurs in a day.

How to speed up drying

In order for the sealing adhesive to dry as soon as possible, it is important to follow the manufacturer's instructions, as well as a few simple rules:

• the product should be applied in one layer. In no case should you make several passes, otherwise they will subsequently delaminate;
• use caution after the initial hardening, i.e. the formation of a thin crust on the surface of the sealant. If you accidentally touch it at this moment, the relief will become uneven, and the seam may come off entirely;
• remember that the wider the seam, the longer remedy will dry, no matter how long is indicated on the package;
• try to create a draft in the room;
• you can lightly spray it with water from a spray bottle, but do not overdo it;
• increase the room temperature. But do not blow on the sealant with a hairdryer in order to avoid its destruction.

Acid sealants have one more thing - they solidify well from exposure to steam, so they should be provided with moisture and an elevated temperature. And neutral ones dry due to the evaporation of alcohol from the composition, so high temperature and dry air can significantly speed up the process.

What type of sealant to choose for the bathroom

You cannot save on this material - penetrating water will spoil the adjacent materials, provoke the appearance of fungus and mold. When choosing a product, pay attention to the adhesion and strength indicators indicated on the label. As a rule, one package is enough for sealing.

The most the best remedy for sealing against moisture penetration of building seams, gluing smooth surfaces, insulating joints in a bathroom or other rooms with high humidity, it is from the group of one-component. This material is easy to work with, gives a strong bond of surfaces and is an excellent waterproofing agent. The main condition for its successful application is to ensure the right time for setting and hardening.

How long does silicone sealant dry? It depends on the properties of a particular type or brand of sealant, as well as on a number of other conditions.

Types of silicone sealants

Silicone sealant is divided into two main groups depending on the composition:

• Neutral;

• Acid.

For repairing heating pipes, plumbing, repairing a kitchen or bathroom, a neutral sealant that is resistant to high temperatures is used. It may contain antifungal additives to keep mold from forming and spreading in sealed areas.

A common neutral sealant contains alcohol or ketoxime, which can be combined with any surface. To give it antifungal properties, acetic acid is included in the composition instead of alcohol or ketoxime, so the acid sealant cannot be used on metal, marble and cement-containing surfaces. It is best used for protecting and bonding plastic, wood or ceramic parts. Penetrating deep into the surface, the acid sealant serves as additional protection for it.

How long does silicone sealant dry?

The drying (curing) time of the sealant depends on its composition and field of application.

Depending on the composition

• The acidic silicone sealant dries in about 4-6 hours from the time of application;

• It takes about 24 hours for the neutral silicone sealant to completely dry and the positive air temperature is from 5 to 40 degrees.

Depending on the area of ​​application

Usually the time for complete drying at optimal conditions is indicated on the packaging of each type of silicone sealant. However, there are a number of factors to consider:

• The outer layer of the sealant hardens to the “peeling off” stage within a quarter of an hour after application, although the polymerization process is still ongoing in its inner layers;

• Polymerization takes place at approximately 2 mm of applied layer thickness in 24 hours;

• At elevated air temperatures, the sealant hardens approximately one and a half to two times faster.

Features of drying bathroom silicone sealant

In order to choose the right sealant for work in the bathroom, you should consider a few basic points:

• Acid-based silicone sealant dries faster - in 4-6 hours, however, it cannot be used to seal joints with metal surfaces so as not to cause corrosion of the metal;

• Neutral sealant is much more expensive than acid sealant, but it can be used on all surfaces. The time for its drying with a layer thickness of 2 mm is 24 hours, provided the air temperature is from 5 to 40 degrees Celsius;

• A sanitary sealant should be used - neutral with the addition of fungicides. This will allow you to further avoid fungus and mold in a room with high humidity;

• If it is necessary to use a sealant for sealing, then the applied layer is usually quite wide and voluminous, therefore, the time indicated on the package of 24 hours for its complete polymerization is not enough. Even if the outer layer hardens after a couple of hours, there is still a liquid sealant inside the joint. For its complete polymerization, it takes at least two days.

Important: The seam should be applied immediately at the desired thickness. Layer-by-layer application of silicone sealant is not allowed.

What can I do to make the silicone sealant dry faster?

There are several ways to speed up the drying of a silicone sealant joint:

• Increase the air temperature in the room to 40 degrees;

• Improve ventilation;

• Lightly spray the already sealed joints with water from a spray gun - moisture accelerates the polymerization process.
