If on the surface that you are going to facing, there used to be a tile lining,
It is necessary to carefully remove the remains of the solution or glue, which can interfere with the clutch of the new glue with the wall and rinse the surface with alkaline foam. Then apply a deep -permanent primer. The cladding can be started after 24 hours.
If there is an old plaster on the wall, then it is necessary to study its condition, how strong it is, for this you need to “tap” the surface – if a deaf sound, then there are defects. Therefore, it is better to knock her down and reduce her again.
