For each case suits its own type of glue-sealant. This is due to the properties of the presented product. There are no universal varieties that are suitable for each type of structure. Therefore, before buying, you should find out what properties the glue-sealant has. This will help ensure the insulation of joints, as well as extend the life of the entire structure. In the course of work, the technology provided by the manufacturer should be followed to ensure the effectiveness of the product in the process of its application.
Classification of sealants
Knowing the properties with which the glue-sealant is endowed, it is possible to determine a suitable variant for yourself. There are several classifications, according to which the sealants are distinguished.
On readiness for use are applied immediately (one-component) or mixed before application (multicomponent).
By the type of basis are silicone, acrylic, bitumen, acrylic-latex, polyurethane and other varieties.
By the way of polymerization, sealants are divided into hardening and non-curing.
Depending on the method of deformation, there are plastic, elastic and plastic-elastic types of glue that can seal seams of plastic, metal, glass, wood, stone and other materials.
Properties important for sealant
There are a number of characteristics that you should pay attention to by buying a sealant for plastic, glass, metal, wood and other surfaces.
Pay attention to the elasticity of the substance, its tensile strength, operating temperature range, adhesion to a certain type of substrate, resistance to adverse environmental effects.
Such influences include ultraviolet radiation, increased humidity, microorganisms, fungi and other factors.
A quality product should compensate for the movement of seams, regardless of the ambient temperature. If necessary, use a sanitary, waterproof sealant.
The main thing - at the very beginning of the work to determine the main qualities that must have a sealant.
The presented type of sealants is used for internal works. He does not tolerate deformation, does not have plasticity.
The main advantage of this product is the ability to paint it after application. Acrylic sealants are used for plastering plasterboard, details of hardboard, when installing window frames and doorways, skirting boards. Also with its help you can restore the old furniture or parquet floor.
Acrylic also quite effectively eliminates cracks in cement and concrete.
Work with this type of sealant in the frost is not recommended, as well as store them in the cold.
Glue-sealant white is slightly cheaper than its transparent version. Therefore, if the substance is subsequently colored, it is better to choose an inexpensive look.
Non-waterproof acrylic sealant
Non-waterproof acrylic sealants are water-based. This makes the product environmentally safe and non-toxic to humans. Such white, transparent or colored glue-sealants do not smell. And if you want, you can dissolve them with water.
However, there are also many shortcomings in the presented substance. It can not be used in wet rooms, as well as at low temperatures. Also, in the case of joint deformation, the non-waterproof acrylic sealant cracked and lost its properties.
Therefore, the scope of such a variety of glue is rather narrow. It can be used for a small repair of furniture, with plasterboard, plinths and other dry surfaces indoors.
Applying such a sealant is not for the purpose, you can in a few days to detect its cracks, depressurization of seams.
Waterproof acrylic sealant
Waterproof sealants have a slightly larger range of applications than the previous version. It is used to work on various surfaces (painted, rough, lacquered). It is more resistant to low temperatures.
Resistance to water in these substances is relative. If you get a drop of water on the seam, nothing terrible will happen. But using a sealant on wet seams is not allowed. Therefore, it can not be used in the basin.
To handle the joints of the bathroom or toilet, the transparent sealant with various additives against the development of the fungus and microorganisms is ideal. These substances are somewhat more expensive than their usual white variants, but their inherent qualities are sometimes irreplaceable.
The most famous acrylic adhesive-sealants of waterproof type is the products of TITAN, KLEO Pro, Moment and others.
By the time of drying, these are medium types of substances (up to 24 hours).
The most common type of sealants are silicones. Their properties allow the use of such products for different types of work.
They can be used on various surfaces. Glue-sealant "Moment universal", "Makroflex SX 101 sanitary" is used for both plastic and metal parts.
Silicone well withstands the adverse effects of temperature changes, precipitation, ultraviolet radiation. Therefore, this variety of sealants are used even for street work.
Such varieties of glue-sealant have high elasticity and strength.
The only drawback of silicone sealants is the inability to paint them in the right color. Manufacturers in this regard began to produce products in a variety of colors. Therefore, when applying the substance on colored surfaces, you should choose a shade of silicone.
Types of silicone sealants
There are two types of silicone sealants. These are neutral and acidic species.
The composition of acid silicones is designed for processing plastic, wooden, stone and ceramic surfaces. However, as a glue-sealant for metal, it is unsuitable, since it rusts the surface in a very short time.
It has a pungent odor that disappears when it dries completely. It is good to use for wood processing. A substance impregnates such a surface.
Neutral sealant is suitable even for metal surfaces. It is used for processing joints of cold water pipes, sewerage and ventilation. Also, such a silicone is popular when laying tiles in a pool, bathroom or kitchen. Heat resistant sealants can be used for hot water pipes, radiators and chimneys.
They stretch well and form a tight seam.
Bitumen glue-sealant of black color is one of the most used types of presented products. He is unpretentious and reliable.
Most often, this sealant is used for wet surfaces. This may be the joints of the roof or foundation.
Glue-sealant black is made on the basis of bitumen and rubber. It is also called a thiocarbon or polysulfide species. They are completely insoluble in water. Prevent the formation of fungus.
One of the most famous such glue-sealants are "Germent" and Penosil Bitum Sealant.
These sealants can not be applied at negative temperatures. Also it can not be painted.
Apply the sealant gradually. After each layer, allow the material to dry well. Handle the substance with care, as it emits harmful substances during installation.
This type of sealant is more than capable of withstanding deformations. The seam treated with this substance is strong, dense and has good elasticity.
This product is often used in the work with glass, dry plaster, wood, chipboard, as well as on painted surfaces.
Often acrylic-latex sealers can be found in processed siding, ventilation, doorways and window frames.
One of the advantages that the present glue-sealant possesses is the ability to stain. With its elasticity, it can be treated after drying with oil paint.
Against the background of other sealants, the adhesive presented has very good elasticity and resistance to deformation.
This glue-sealant is often used by motorists, since the substance is not afraid of the weather conditions or the effects of chemicals.
It is often used in working with complex surfaces, for example, aluminum, reinforced concrete, ceramics, stone, etc.
The only drawback of polyurethane sealant is its toxicity. This substance is caustic and quite dangerous if the rules for its use are not observed. Most often because of these characteristics, the polyurethane sealant is not used for internal work. The main field for this product is work outside the home.
This is the ideal sealant for the treatment of the facade and roof. Due to the ability to withstand stretching, bending, shearing, this substance is widely known as an automotive adhesive. Due to the choice of its color, it can be applied without any subsequent painting for various joints.
How to wipe the sealant
For water-insoluble sealants, the easiest way to remove is a mechanical action. This method can be used at home without additional funds.
With a knife, spatula or other similar tool, the old layer is simply cut off. This should be done very carefully, so as not to damage the surface.
On sale there are chemical agents that can soften a thick layer of sealant. Then the agent removes the old glue from the seams.
Acrylic waterproof and polyurethane sealants can only be removed by cutting the old layer. They are not affected by various chemicals.
The most famous chemical remedies for removing the old sealant are Silicon-Entferner, Soudal Sealant Remove. They allow you to remove silicone from ceramic, enamel and plastic.
Choosing a sealant for certain needs, you should familiarize yourself with all the properties of this type. Universal means of processing seams and surfaces simply does not exist. Having identified the necessary qualities that the sealant must possess, you can choose the correct version of it. According to the manufacturer's instructions, it is possible to apply each type of the presented product as efficiently as possible.
