The surface to be strengthened must by clean and dry. Any holes and cracks are filled in with a suitable plaster. If necessary, the entire substrate is filled over
The best result for the base to be levelled is obtained by fixing the reinforcing fabric with screed mass. First, a layer of screed mass and the reinforcing fabric of the wall surface is pressed onto it with a spatula. The seams of the fabric are overlapped with each other by 10cm. The second layer of screed mass is applied on top of the hardened base screed layer.
We do not recommend the use of ordinary glue or paint to attach the strengthening membrane if the plan is to apply finishing plaster on it. This is because the layer of finishing plaster may moisten the glue surface, causing the strengthening membrane to come off the substrate.
