How to treat XPS extruded board?

In the overall construction process of the extruded board, the plastering is also a crucial step, whether it is the ground or the wall laying the extruded board, only the underside plastering and the surface layer plastering, in order to play its greater use value, the following with the extrusion board manufacturers to understand how to deal with the extrusion board plastering.

Before applying polymer mortar to the bottom, clean the bottom surface of the extruded board first, apply the interface agent on the surface, wait for dry until the hand is not sticky, and then apply the polymer mortar evenly on the bottom surface of the extruded board, and try to control the thickness of about 2mm. Before applying polymer mortar on the surface layer, first apply an appropriate amount of binder on the surface of the mesh cloth to bond the fixed mesh cloth, such as after the binder is dry, and then apply polymer mortar on the surface layer, pay attention to control the thickness, if the plaster layer can just cover the mesh cloth, then the thickness is appropriate, generally about 1mm.

If the ash layer is too thick, it is easy to lead to a large gap between the extruded polystyrene board and the wall after the laying and fixing, which affects the use effect in the later period, so it needs to pay more attention.
