Fireproof sealants belong to the construction materials, which combine several qualities. Such material can be used to fill joints or various cracks, repair chipped masonry in the fireplace or during other types of work on the surfaces, which are used at high temperatures or come into contact with open fire. Thus, fire sealant is used for internal fireproofing work.
The main areas of application of refractory sealants made on the basis of silicone or acrylic, are works on sealing a variety of gaps formed between the floor and walls. This material is also used for processing joints between the wall and window frames.
But the main purpose of fire sealants is to use them as a filler for panel cavities with fire-resistant status. Also, this material is very widely used in the laying of heat routes, installation of structures made of concrete, steel, brick.
As the main advantage of fire sealants should be noted excellent adhesion to various surfaces, including porous. You should also take into account the fact that acrylic fire sealants are elastic, which allows its use when sealing deformed joints. Such sealants can be applied to both dry and wet surfaces, so you can work with this material in all weather conditions.
All fire sealants have a certain resistance class. As for the types of refractory sealants, they are distinguished on the basis of the base on which they are made. The base material can be silicone or liquid glass.
Choose a sealant to use based on the characteristics of the surface to be treated and the general nature of the work. Generally, all types of refractory sealant have the same properties, but, nevertheless, each of them has its own characteristics, since they have different curing time and withstand temperature threshold, the level of gas tightness and the amount of shrinkage.
Choose fire-resistant sealants for use with great responsibility, because it sometimes depends on the fire safety of the building, its individual rooms, and sometimes the lives of the people in them.
