Direct contact between cement-based tile adhesives and magnesite screeds leads to the destruction of the magnesite screed due to a chemical reaction. Rear moisture permeation from the substrate must be excluded using appropriate measures. Mechanically roughen the magnesite substrate, prime with the epoxy resin ASODUR-GBM and whilst the primer is still wet, broadcast to excess with 0.5 - 1.0 mm quartz sand. Tiles can be installed after waiting a further 12 – 16 hours approximately.
