Glass Mat exterior wall insulation coating finishing construction technology

Glass Fiber coated with alkali-resistant polymer emulsion. Glass Mat series products: alkali-resistant GRC fiberglass Glass Mat, alkali-resistant wall and stone Glass Mat, marble Fiber Glass. Glass Mat has good chemical stability and can resist acid, alkali, water, cement erosion and other chemical corrosion.

High strength, high modulus and light weight, so it has good impact resistance. It has good dimensional stability, is stiff, flat, not easy to shrink and deform, and has good positioning. It can prevent mildew and insects. It has the functions of fire prevention, heat preservation, sound insulation and insulation. Construction process of Glass Mat exterior wall insulation paint finish: The reasons for cracking of paint finish exterior insulation wall surface due to construction factors are:
(1) The Glass Mat has dry overlap or insufficient overlap: cracks will form at the overlap.
(2) The Glass Mat is laid close to the insulation layer: it cannot resist cracking, and the plastering mortar layer is prone to cracks.
(3) The four corners of the door and window openings are not covered with fiberglass Fiber Glass along the 45° angle: cracks are prone to appear at the four corners of the door and window openings where stress is concentrated.
(4) Winter application: prone to cracking, hollowing, and falling off.
(5) When pasting the polystyrene board, one end is raised, causing the board surface on the other side to be empty and hollow. During construction, the Glass Mat will be knocked, slapped, or vibrated on the board surface, causing the glue to fall off.
(6) When the reinforcing Fiber Glass material of the surface layer is steel Fiber Glass, if anti-cracking mortar is not used as the surface layer plastering material, but ordinary cement mortar or cement mortar with only a small amount of fiber is used as the surface layer plastering material, then Cracking may occur due to excessive differences in linear expansion coefficients of materials such as steel bars, cement mortar, polystyrene boards, and cold-drawn steel wires in the layers, resulting in inconsistent deformation.
