Why use fiberglass self-adhesive mesh for wall cracking
Fiberglass self-adhesive mesh plays an important role in external wall insulation, but the stubborn problem of wall cracks has been plaguing people for many years. The anti-crack effect, the uniform warp and weft of the fiberglass self-adhesive mesh has a strong tensile breaking strength, and the intersection of the warp and weft is not easy to slip when it is stressed, so that the self-adhesive mesh belt plays a good role on the wall. anti-cracking effect.
The usage of fiberglass self-adhesive mesh in old and new walls is different. Some experienced construction masters do not recommend the use of self-adhesive mesh tape in a large area, but it is not necessary to prevent problems before they occur. Generally, the most commonly used building areas are the connection between the new wall and the old wall, the hollow repair of the wall, the slot to fill the junction, some corner joints, etc., all need to use fiberglass self-adhesive mesh.
Interior wall fiberglass self-adhesive mesh: The interior wall thermal insulation alkali-resistant glass fiber mesh is made of medium-alkali or alkali-free fiberglass self-adhesive mesh tape as the base material and then coated with modified acrylate copolymer glue. It has the characteristics of light weight, high strength, temperature resistance, alkali resistance, waterproof, corrosion resistance, crack resistance and dimensional stability.
The fiberglass self-adhesive mesh can effectively avoid the overall surface tension shrinkage of the plastering layer and the cracking caused by external force. The light and thin self-adhesive mesh belt is often used for wall renovation and interior wall insulation.
