Sealant for outdoor use

You can buy frost-resistant waterproof sealants for outdoor work in Balashikha at a price of 192 rubles per 300 ml cartridge. These are specialized series, resistant to low temperatures. The waterproof sealant may be silicone, acrylic, or polyurethane. But bitumen or butyl, which requires heating, is not suitable for such tasks.

Frost-resistant sealants for outdoor work are produced by Moment, Macroflex, Ceresit, Tytan, Akfix, Elasil, Penosil, Sikaflex, Krass and other well-known brands. Modern compositions are used for concrete, metal, brick, stone, wood, plastic, glass and roofing.

Frostproof sealant for external works

When choosing, you need to consider the type of base and features of a particular composition.

  • The average temperature range of waterproof silicone is from -50 to +200 degrees. There are high temperature and fire resistant brands. Silicone can not be painted, so you immediately need to choose black, white, gray or color for the finish.
  • Even waterproof acrylic is best used for interior use. It withstands up to -20 degrees and adheres well to various bases, but is sensitive to external influences.
  • Acrylic-silicone sealants combine the advantages of two materials, as MS-polymer. They are not afraid of ultraviolet radiation, contain fungicides and withstand from -40 to +80 degrees. And on top of them can be painted with oil or latex facade paints.
  • Waterproof polyurethane is also frost resistant. It can withstand up to -60 degrees. On its basis, polyurethane foam is produced, which differs from the sealant in structure.

How to apply frost-resistant and waterproof sealant

Even special sealants for outdoor applications have their own operating temperature range. Often it differs from what frosts an already frozen mass can withstand. Some frost-resistant compositions can still be applied only at +4 - +30. With polyurethane work up to -10 degrees.

Pay attention to the solidification time of the mass and the conditions that are necessary for this. If they are violated, the frost-resistant sealant hardens for too long. And because of this, its structure is violated. The final curing process can take several days. In the most severe regions, it is recommended to wait a week before further finishing.

Frost-resistant and waterproof sealants for outdoor use

The composition for sealing joints is presented in different types, different in purpose and technical characteristics:

Each of the options is designed for operation in various conditions. In addition, the materials of this group are divided into types, taking into account the composition:

They are often similar in effectiveness. However, if a one-component waterproof sealant can differ in simplified characteristics, then its two-component analog in most cases is universal, durable, reliable. The service life of materials depends not only on the constituent substances, but also on compliance with operating conditions. For example, to fill the gaps in a region where in winter the air temperature often drops below 0 ° C, it is recommended to purchase a frost-resistant sealant.

The materials differ in color:

  • white sealant
  • the black,
  • brown,
  • color - you can choose a mixture of the most suitable tone in accordance with the shade of the processed surface.

White material is most often used to eliminate leakage of plumbing fixtures. However, it can also be used to fill light seams. Black sealant has improved properties. Such types of compositions are often characterized by resistance to ultraviolet radiation. This increases the service life of the coating, and in addition they retain their original color, do not fade.

In addition, transparent material was widely used. It goes unnoticed on the surface. This variety can be used to repair any structures, regardless of color. When a weatherproof sealant is selected, it is recommended to take into account the type of material with which the composition will be in contact. So, there are universal mixtures that are suitable for different surfaces. The range includes highly specialized materials. These include a sealant for metal, there is also a composition for the repair of wooden structures.

Features of silicone sealing

The materials of this group are distributed more than others. They differ in a number of advantages, and in addition are relatively cheap in comparison with analogues. Waterproof silicone sealant can be used for finishing and repair work inside and outside the premises.

Available in a plastic tube designed for installation in a construction gun. The tip is cut to a sufficient length, while the hole will vary in diameter, which allows you to fill the seams of different widths.

Despite the viscous structure, the composition includes silicon - a component characterized by hardness. Based on it, a polymeric material is made, which is used in the manufacture of silicone sealant for exterior work and interior decoration. The composition of such a mixture includes components that improve its properties:

  • silicon dust (crushed silica sand or glass),
  • antiseptic additives that prevent the development of mold in the structure and on the surface of the material,
  • components designed to reduce the viscosity of the mixture, thereby improving adhesion, because silicone sealant for external joints and interior finishes with these characteristics better fills minor defects on the surface to be treated,
  • coloring pigment.

Technical characteristics of the materials of this group:

  1. Increased elasticity, which ensures resistance to mechanical damage, cracks in the suture joint made of silicone do not appear.
  2. Tensile strength. This type of sealant is able to withstand the effect of the force, which contributes to repeated stretching of the material, in addition, the silicone compound tends to return to its original shape, thanks to this property, the sealant withstands the shrinkage of the structure, the displacement of the connected parts, transfers the cold, and repeatedly passes through the freezing / thawing cycle without loss of property .
  3. Universality: such a sealant is suitable for plastic, glass, metal, wood, because it is characterized by high adhesion.
  4. Silicone does not absorb moisture; in addition, it is resistant to fungus.
  5. Good tolerance of ultraviolet radiation.
  6. Silicone compounds can withstand temperatures ranging from -50 ... + 200 ° C.

When choosing such a material, it is necessary to take into account its intended purpose. So, if you need a facade sealant, you need to pay attention to the mixture, which includes coloring pigments, which will allow you to choose the right shade in accordance with the exterior of the object. When the composition will be operated in rooms with high humidity, it is better to use a material that includes antiseptic components.

When buying such a sealant, you need to pay attention to the type of hardener. This component is found in 2 versions: acidic, neutral. This may affect the choice of material of the processed surface. So, acid mixtures are not intended for coupling with metal, concrete structures, as well as marble products. This will damage the coating. Neutral compounds (contain alcohol or ketoxime) are universal. They do not contain too aggressive components, which makes it possible to apply such materials to different surfaces.

Polyurethane Composition

This option is superior to the silicone counterpart in a number of ways. So, it withstands the effects of lower temperatures. However, there are also disadvantages. This is a versatile material. It is used for repair, insulation of surfaces. Do not confuse polyurethane and polyurethane foam. These are different materials. The last of them increases in size when applied, has a foam structure, quickly hardens. Polyurethane is a plastic material that dries longer. Its properties:

  • moisture resistance, sealant retains its basic characteristics even with prolonged contact with water,
  • high adhesion
  • quick solidification
  • Long service life
  • UV resistance
  • elasticity allows the coupling of structural elements even in the absence of their rigid fixation,
  • the ability to withstand low temperatures in the range of -60 ... + 120 ° C, which is much lower compared to the silicone counterpart.

Due to the presence of harmful substances in most cases, polyurethane mixtures can be used outdoors, since toxic components are released during the drying process. If the sealant is planned to be used on a non-residential facility or there is an opportunity to leave the apartment during the repair, it is permissible to use this type of composition.

Another of its features is the need to moisten the treated surface, since under such conditions the properties of the material are improved. Its advantage is the absence of shrinkage after solidification. In addition, the sealant is characterized by moderate viscosity, due to which it is held on vertical surfaces, does not drain.

Polyurethane can be used to fasten structural elements from different materials: metal, wood, ceramics, plastic, concrete. It is permissible to paint this material, which allows one sealant to be used to repair surfaces of different shades: at the end of work and after solidification, the mixture is covered with paint of the desired color. There is a lack of interaction between polyurethane and paints and varnishes.

Acrylatex Sealing

The compositions of this group are also characterized by resistance to moisture. It is noted that this is frost-resistant acrylic sealant. The materials of this group well tolerate prolonged exposure to ultraviolet radiation, temperature extremes. Such mixtures are used for exterior and interior use.

  • the strength of the suture joint, at the same time, its elasticity is noted,
  • resistance to deformation loads: cracks during shrinkage and a small displacement of the fastened surfaces relative to each other are not formed,
  • Acrylic sealant can be painted, this will not affect the properties of the material,
  • withstand temperature: -20 ... + 70 ° С, which limits the scope of such compositions,
  • acrylatex sealants are more resistant to moisture compared to the classic water-dispersed counterparts.

The disadvantage of acrylic sealant for outdoor use is its short service life. So, after 2-3 years, it is recommended to update the protective material. Acrylatex compounds acquire the ability to resist the effects of water after solidification. Siliconized analogs may be exposed to moisture immediately after application.

Given that such sealants may vary in composition, the degree of elasticity also varies. So, the classic acrylic material is more exposed to deformation loads, because it weakly stretches, poorly retains its shape. Acrylatex, siliconized sealants are more flexible. They can stretch 2 times the original shape.

Two component formulations

By elasticity, such a material is not inferior to the previously considered analogues. A feature of such sealants is the need for preliminary preparation. They are produced in the form of individual substances that must be mixed. It is important to obtain a solution of a uniform consistency. To do this, use a construction mixer.

The sealant of this group is universal, it can be used for coupling structures made of different materials: concrete, metal, etc. The composition resists the effects of ultraviolet radiation. The advantage is resistance to negative external factors. To improve the properties of the material after solidification, it is treated with paint.

The composition of such sealants includes the main component (may differ depending on the grade of material) and hardener, due to which a mixture of the desired consistency is obtained. The two-component mixture withstands the effects of temperature extremes, but the upper and lower limits of the range vary depending on the type of main component.

Representatives of frost-resistant compounds

When choosing roofing or facade sealants pay attention to their ability to withstand low and high temperatures. If most of these compounds can be used in hot climates, not all varieties are intended for use in cold weather. For this reason, it is important to correlate the conditions of use of the sealant and its type. Common types of frost-resistant mixtures:

  1. Titan Wild. Differs in white color. This is a universal option, can be used to repair structures of different materials. It is made on a silicone basis. The tool can be used inside and outside the object. With its help, often fill the cracks (in windows, doors), connect drywall.
  2. Ettrilat PU25. This is a single component composition. It is made on the basis of polyurethane. Suitable sealant for concrete, metal, wood and other materials, due to its ability to bind to different coatings. This variant of the mixture can be operated at a temperature of -40 ... + 90 ° С. Drying speed - 3 mm per day.
  3. Rubberflex is a polyurethane sealant. It is represented by different options that are different in purpose. So, there is a separate composition for working with wood. You can purchase sealant for application to concrete. There is material of this brand for working with glass. Developed a mixture for use in the automotive industry.

Scope of use

The sealant can be applied to different surfaces, it all depends on its type and type of components included in the composition. Application area:

  • furniture repair
  • elimination of leakage of pipes, plumbing fixtures,
  • insulation of surfaces, while sealant is used to fill gaps, various leaks,
  • repair of windows, doors,
  • filling the gaps between the concrete floor and the wall,
  • Automotive industry,
  • filling joints between bricks, tiles,
  • roofing: sealing joints of various structural elements (antenna outlet, chimney), etc.

The scope is not limited to these areas, because the sealant can be used for joining structural elements at any objects.

Consumption

In order to calculate the amount of composition for protecting the coating, filling the gaps, it is necessary to determine the parameters of the sections that are planned to be processed. So, measure the cracks. For this, the depth and width of the gap are determined. The values ​​of these parameters must be multiplied. As a result, you can get a value corresponding to the consumption of sealant on 1 m of the surface.

Additionally, the type of material of the treated surface is taken into account, since the degree of filling of the pores of the coating will depend on this. Sealant can be purchased in small tubes. This will allow you to repair a small area.

Bitumen sealant - a special kind

Such material is often used to repair the foundation, concrete structures, roofing. Bitumen sealant contains the component of the same name. Due to bitumen, the properties of the mixture improve: it acquires moisture resistance, strength. Such compositions are in most cases characterized by black color, but when aluminum powder is added, a metallic luster can be obtained. Bitumen mixtures containing polymer additives are popular. Their advantage is resistance to cracking during solidification, shrinkage.

Scope of application

Frost-resistant and waterproof sealants are used in the winter season, because other options will not cope with the climate. In construction, this material is used to seal roof seams, especially if it is made of modern materials, because they need additional protection along the joint line. Facade sealant will help to hide any defects on the front side of the building, and the ability to stain this material makes it invisible, which is very convenient.

For prefabricated houses, cracks that cause drafts, especially noticeable in winter, are a very common problem. With just one sealant, you can get rid of this situation, but only if the cracks are small. In addition to the upper part of the building, you should pay attention to the lower one, because the whole foundation is the key to the durability of the building and its reliability. The sealant, due to its universal qualities, is able to stop cracking of the base and strengthen it for many years.

Outside of both new and old buildings, there are always some flaws that need to be addressed in the early stages, while the damage is minimal and can be dealt with using simple means. Using universal silicone sealant, you can connect the parts of concrete and metal, fill in the voids and adjust what initially failed or deteriorated over time.

It is especially easy and effective to use sealant during installation or repair of windows. Inside, it is important to trim everything so that no traces of this substance are visible, but at the same time that all the slots are securely closed. Outside, you can pay more attention to protecting the window opening, filling all the cracks with sealant. By choosing a transparent option, it will be possible to find where the work has been done on the façade, and using the color options will help mask the area where the repairs were carried out.

The scope of use of the sealant is large and it is difficult to imagine the repair of any room both inside and outside without using this building mixture.

Thanks to the varieties that were invented, you can easily find the right option and not doubt its effectiveness.

What temperature does it withstand?

Construction work is most often not carried out in the winter, but there are always exceptions. There are emergency situations when you have to repair the house outside in any weather, solving a problem that suddenly arises. In such a situation, the temperature outside the window can be very different, which depends on the region, therefore it is important to use building materials and mixtures correctly.

To work in freezing temperatures you need to purchase a frost-resistant version of the sealantwhich does not lose its properties even at -60 degrees. Low and extra low temperature indicators can affect the quality of work. That is why the use of a suitable sealant will help to cope with the situation quickly and get a good and high-quality result that will not collapse by the next season.

If we talk about high temperature indicators that can withstand thermal sealants, then the maximum is +200 degrees Celsius, which can occur when working with heating facilities or appliances. In addition to choosing a heat-resistant composition, it is worth taking care of protecting the body from exposure to high temperatures.

Any time of the year dictates its features and it is important to know and take them into account, then there will be no problems with repair or construction. Waterproof, heat-resistant and frost-resistant sealants will be able to cope with rainy weather, heat or high temperature and freezing temperatures, while ensuring the proper result when working with seams, joints and cracks anywhere on the facade.

It is worthwhile to focus on indicators of the temperature of the surface on which the work will be carried out. It is best that it be in the range from +4 to +30 degrees, while the ambient temperature can be from -40 to +120 degrees. Knowing the temperature of the surface is important in order to be able to calculate the time it takes for the sealant to completely dry out, after which it can be painted and the repair completed. If the average layer thickness is 10 mm, then the temperature of the surface on which the composition was applied should be at least +25. The optimal indicators of the drying time of the composition will be one day.

If the surface has not been prepared, then adhesion to it will be worse and silicone will dry much longer. When preparing the surface for work, it is important to clean it of dirt and dust and dry it, otherwise the result will be much worse.

The properties of the sealant are preserved after fifteen cycles of freezing and thawing at a temperature of -15 degrees, which indicates the durability of this building material and its resistance to weather vagaries.

Tips

In order to purchase high-quality frost-resistant and moisture-proof sealant and its proper use, you need to know certain nuances:

  • When purchasing a tube with a composition, it is worth studying it and checking the expiration date, because even high-quality material will not be so effective after the end of its service life.
  • When choosing a tube with a sealant, it is important to study it well for mechanical damage, because it will negatively affect the contents, and you should not expect a good result from using such a tool.
  • It is important to choose the right silicone for a certain type of work. Frost-resistant is taken for the facade, which will be exposed to cold, but not used near stoves, and vice versa.
  • When choosing a sealant from a number of similar ones, it is worth giving preference to a proven product and a well-known brand. The price for it is often a little higher, but you can be completely confident in the quality of the products.
  • When planning a trip for building materials, it is better to choose a construction supermarket than the market, because the store has special conditions for storing any goods, all have certificates and a guarantee that can hardly be seen at a market merchant.

If the repair using sealant is coming for the first time, you should take care of the availability of the right amount of compositionby calculating the consumption per m2, which will significantly speed up the process. It is necessary to carry out the sealing of any areas slowly and having full confidence in what needs to be done. If there is no experience in using silicone, you should read about the intricacies of its use and watch visual video tutorials, then closing up any defects inside and outside the room will not be a problem, whether it be interior walls or the decoration of the passage between them.

It is possible to use frost-resistant and water-resistant versions of the sealant indoors, but often the scope of use relates specifically to facades, roofs and foundations, which are subject to negative influences. Construction and repair became much easier with the advent of such mixtures, which even a layman can use.
