How to handle the interface of rubber powder polystyrene particle insulation mortar

The interface mortar can ensure the adhesion of the rubber powder polystyrene particle insulation mortar and prevent the rubber powder polystyrene particle insulation mortar from hollowing and cracking. Therefore, it is very important to carry out interface treatment of rubber powder polystyrene particle insulation mortar. Let’s talk about the interface treatment method of rubber powder polystyrene particle insulation mortar.

Interface treatment method of rubber powder polystyrene granule thermal insulation mortar
First spray water to moisten the dry wall base surface to weaken its water absorption capacity, and then apply rubber powder polystyrene granule thermal insulation mortar specially The thickness of the interface mortar is about 1MM. When the special interface mortar for rubber powder polystyrene particle insulation mortar still has good viscosity, apply rubber powder polystyrene particle insulation mortar (the thickness should not exceed 2CM each time). After the first layer of insulation mortar is stable, , apply the second layer of rubber powder polystyrene particle insulation mortar. After the second layer of rubber powder polystyrene particle insulation mortar is stable, spray water to moisten the insulation layer before applying the anti-crack mortar, and then apply the anti-crack mortar. The insulation layer is dry and After the strength of the anti-cracking mortar is stable, the exterior wall can be scraped with anti-cracking putty and painted with exterior wall paint.
