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
If the substrate is levelled, the best way to attach the strengthening membrane is by using the finishing plaster. The strengthening membrane is pressed against the first layer of the finishing plaster, with the second layer being applied the usual way.
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.
