How to apply scrapped Monocouche onto smooth concrete

 

 

Case

Little, no suction or no mechanical key

In order that the render bonds to the substrate it will require both suction and a good key coat.

On the concrete surfaces we could face the mould release agent that could affect the adherence of the render.

Crack and debonds

Smooth concrete may offer the worst of all conditions for all rendering, with the possibility of residual traces of release agents and both poor key coat and low suction.
