Exterior wall insulation crack-resistant mortar is an important component of the anti-crack protective layer in the exterior wall insulation system. It is applied to the surface of the insulation layer during construction. During construction, in addition to the tensile bond strength, water immersion tensile bond strength, and compression ratio of anti-cracking mortar, the construction thickness is also very critical.
The construction steps of the anti-crack protective layer in the insulation system are: anti-crack mortar, mesh cloth (or steel wire mesh), anti-crack mortar. Now apply a layer of anti-crack mortar on the insulation layer and press it into the grid. cloth (or steel mesh) and wait 24 hours before applying anti-crack mortar again. And what is the appropriate thickness of the anti-crack mortar for construction? Under normal circumstances, the thickness of the first coat of anti-crack mortar should be controlled at 2-3mm. After the mesh cloth (or steel mesh) is laid, the second coat of anti-crack mortar should be applied. The total thickness of the two coats of anti-crack mortar should be It should be controlled at about 4mm.
The anti-crack protective layer plays the role of protecting the insulation layer, preventing cracking, waterproofing and impact resistance in the thermal insulation system. Therefore, in addition to ensuring the quality of the anti-crack mortar, the construction quality must also be strictly required.
