Warning: Last items in stock!
Treatment of gypsum and anhydrite surfaces before the installation of ceramic tiles or stone material with cementitious adhesives. Mapeprim SP improves the bonding of smoothing and levelling compounds such as Ultraplan and Planolit on very smooth and compact substrates such as ceramic tiles, natural stone and wood. Apply the levelling compounds while Mapeprim SP is still "indentable" and before it has completely hardened.
Use Mapeprim SP on dry substrates and not subject to rising damp.

Mapeprim SP is a primer consisting of two components (A+B). After accurate mixing, application to the substrate, and drying, Mapeprim SP hardens to a compact film resistant to water and ageing.
Since Mapeprim SP is dispersed in water, it therefore presents no inflammability problems and can be stored with no special measures taken.
