For each case its own type of adhesive sealant. This is due to the properties of the presented product. There are no universal varieties that are suitable for each type of construction. Therefore, before buying, you should find out what properties the adhesive-sealant has. This will help ensure the reliability of the insulation of the joints, as well as extend the life of the entire structure. In the course of the work, the technology provided by the manufacturer should be followed to ensure the effectiveness of the product in its application.
Knowing the properties with which glue-sealant is endowed, one can determine a suitable option for oneself. There are several classifications by which sealants are distinguished.
When ready for use, they are used immediately (one-component) or mixed before application (multi-component).
The types of bases are silicone, acrylic, bitumen, acrylic-latex, polyurethane and other varieties.
According to the method of polymerization, sealants are divided into hardening and non-hardening.
Depending on the method of deformation, there are plastic, elastic and plastic-elastic types of glue capable of sealing the seams of plastic, metal, glass, wood, stone and other materials.
Properties important to sealant
There are a number of characteristics that should be paid attention to when buying adhesive sealant for plastic, glass, metal, wood, and other surfaces.
Attention should be paid to the elasticity of the substance, its tensile strength, operating temperature range, adhesion to a specific type of substrate, resistance to adverse environmental influences.
Such effects include ultraviolet radiation, high humidity, microorganisms, fungi and other factors.
A quality product should compensate for the movement of joints, regardless of the ambient temperature. If necessary, you should use sanitary, waterproof glue-sealant.
The main thing - at the very beginning of the work to determine the basic qualities that must have a sealant.
The presented type of sealants is used for interior work. It 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 puttying drywall, hardboard parts, when installing window frames and doorways, baseboards. Also, it can be used to restore old furniture or parquet floors.
Acrylic also quite effectively eliminates cracks in cement and concrete.
It is not recommended to work with this type of sealants in the cold, as well as to keep them in the cold.
White adhesive sealant is slightly cheaper than its transparent version. Therefore, if the substance is subsequently painted, it is better to choose an inexpensive form.
Waterproof Acrylic Sealant
Non-water resistant acrylic sealants are water based. This makes the product environmentally safe and non-toxic to humans. Such white, transparent or colored adhesive-sealants have no smell. Yes, and if desired, they can be dissolved with water.
However, the flaws in the presented substances are also many. It can not be used in wet areas, as well as at low temperatures. Also in the case of deformation of the seams of the structure, the non-resistant acrylic sealant will crack and lose its properties.
Therefore, the scope of application of this type of glue is quite narrow. It can be used for a small repair of furniture, with drywall, baseboards and other dry surfaces indoors.
Applying such a sealant for other purposes, in a few days it is possible 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 for work on various surfaces (painted, rough, varnished). It is more resistant to low temperatures.
Resistance to water from such substances is relative. At hit on a seam of drops of water anything terrible will not occur. But it is not allowed to use sealant on wet joints. Therefore, it cannot be used in the pool.
Glue-sealant transparent with various additives against the development of fungus and microorganisms is ideal for treating the seams of a bathroom or toilet. These substances are somewhat more expensive than the usual white versions, but their inherent qualities are sometimes irreplaceable.
The most famous acrylic adhesives, sealants of waterproof type are the products of TITAN, KLEO Pro, “Moment” and others.
By drying time, these are medium types of substances (up to 24 hours).
The most common type of sealants are silicones. Their properties allow the use of similar products in various types of work.
They can be used on various surfaces. The adhesive sealant “Moment Universal”, “Makroflex SX 101 sanitary” is used for both plastic and metal parts.
Silicone well withstands the adverse effects of temperature extremes, precipitation, ultraviolet radiation. Therefore, this kind of sealant is used even for outdoor work.
Such types of adhesive sealant have high elasticity and strength.
The only drawback of silicone sealants is the inability to paint them in the desired color. In this regard, manufacturers began to produce products in various colors. Therefore, when applying the substance to 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 varieties.
The composition of acidic silicones is designed for processing plastic, wooden, stone and ceramic surfaces. However, as an adhesive sealant for metal, it is unsuitable, as it exposes the surface to rust in a very short time.
It has a pungent odor that erodes when fully dried. It is good to use for processing wood. Substance impregnates such a surface.
Neutral sealant even suitable for metal surfaces. It is used to handle the joints of cold water pipes, sewage and ventilation. Also, such silicone is popular when laying tiles in the 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.
Black bituminous adhesive sealant is one of the most widely used types of products presented. It is unpretentious and reliable.
Most often, this sealant is used for wet surfaces. It may be the joints of the roof or foundation.
Black adhesive sealant is made on the basis of bitumen and rubber. It is also called thiokol or polysulfide species. They are completely insoluble in water. Prevent the formation of fungus.
One of the most famous of these adhesives and sealants are “Germent” and Penosil Bitum Sealant.
Such sealants should not be applied at negative temperatures. Also it can not be painted.
Apply sealant gradually. After each layer, let the substance dry well. Handle the substance with care as it emits harmful substances during installation.
Acrylic latex sealant
This type of sealant is more able to withstand deformation. The seam treated with this substance is strong, dense and has good elasticity.
This product is often used in work with glass, dry plaster, wood, chipboard, as well as on painted surfaces.
Often, acrylic-latex sealants can be found in machined siding, ventilation, door openings and window frames.
One of the advantages that presents the glue-sealant, can be called the ability to staining. With its elasticity, it can be processed after drying with oil paint.
Compared to the rest of the sealants, the presented adhesive has a very good elasticity and resistance to deformation.
This adhesive sealant is often used by motorists, as the substance is not afraid of weather conditions or the effects of chemicals.
It is often used in work with complex surfaces, for example, aluminum, reinforced concrete, ceramics, stone, etc.
The only disadvantage of polyurethane sealant is its toxicity. This substance is caustic and rather dangerous if it is not followed. Most often because of these characteristics, polyurethane sealant is not used for interior work. The main focus for this product is work outside the home.
It is an ideal sealant for the treatment of the facade and roof. Due to its ability to withstand stretching, bending, shearing, this substance is widely known as automotive adhesive sealant. Thanks to the choice of its color, it is possible to apply it to various joints without subsequent coloring.
How to wipe off sealant
For water-insoluble sealants, mechanical impact is considered the simplest method of removal. This method can be applied at home without attracting 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 chemicals that can soften a thick layer of sealant. Then the tool removes the old glue from the seams.
Acrylic waterproof and polyurethane sealants can be removed only by cutting the old layer. They are not affected by various chemicals.
The most well-known chemicals today for removing old sealants are Silicon-Entferner, Soudal Sealant Remove. They allow you to remove silicone from ceramics, enamel and plastic.
Choosing adhesive sealant for specific needs, you should be familiar with all the properties of this type. Universal means of processing seams and surfaces simply do not exist. Highlighting the necessary qualities that a sealant should have, one can choose its variety correctly. Guided by the manufacturer's instructions, you can most effectively apply each type of product presented.
