What is hidden under the word sealant? In fact, this is a composition that can be pasty or viscous, and it is used to fill the compounds, gaps, cracks in various designs. Sealants are made on the basis of polymers and they are intended to achieve effective sealing.
Features of sealant for furnaces.
In addition to their main function — the heating of the room, stoves and fireplaces create comfort, fully justifying the values of the hearth. Crowing firewood in the fireplace, contemplation of the fascinating game of flame pacifies and soothes. A special magic also blows from a quietly buzzing furnace.
Therefore, many owners of private houses and cottages, when building, add stoves and fireplaces. Having these designs in the interior of the house, you need to constantly take care of their condition, monitor heat transfer and safety. An important task in this matter is the meticulous work on the sealing of cracks arising during the operation.
And here a sealant for stoves and fireplaces comes to the rescue, since it is intended for long -term repairs, as well as filling the compounds, formed cracks and cracks in the designs of fireplaces, furnaces, furnaces and chimneys. It has quite advantages, which, without a doubt, experts include:
excellent agdosion, that is, clutch with any materials;
high heat resistance: 1250 — 1500 degrees;
The absence after the cracks is hardened, it also does not crumble;
strength and good resistance to deformations;
elasticity and durability;
absence in its composition asbestos.
Scope.
Heat -resistant sealants are used to perform the following works:
filling out the formed cracks in the furnace and ventilation ducts, fireplaces;
sealing sealing furnaces, fireplaces, chimneys and sieves;
Repair of various building structures and their elements that are exposed to fire.
But you need to pay attention to the fact that its use is unacceptable for the repair of the central heating system, various gas equipment, as well as elastic connections.
Apply sealant on a pre -cleaned surface. Repaired, for example, the fireplace must be thoroughly cleaned from settled particles of dirt and soot. Fat surfaces are advised to degrease with acetone. As for the porous surfaces, it is advisable to moisten them with water before applying for sealant, this will provide the best adhesion of materials.
Types of sealants.
In their composition, sealants can be one -component, two -component and consist of more than two components. In the first version, the sealant is ready for direct use. In the second case, it is supposed to mix the components in clearly provided proportions.
Especially popular are heat -resistant sealants on a silicate basis. Fiberglass is added to their composition, due to which resistance to deformation is achieved, and when sealing cracks and seams, a solid layer is created. It is impenetrable for smoke and gas. Fireproof sealants are of high quality and meet all the requirements for modern materials.
