For the protection of concrete surfaces against acids the first step is to coat the surface with the negative side waterproofing KÖSTER NB 1 Grey or the faster version KÖSTER NB 1 “fast”. The acid protection itself is made with KÖSTER VE (also suitable for damp substrates) or KÖSTER PSM (suitable for dry substrates and easy to apply).
Where acid resistant tiles are to be applied KÖSTER VE can be used as a tile adhesive and grout.
Always adhere to the specifications in the respective Technical Guidelines.
