Mapei Prosfas Consolidating Compound For Weak Screeds 25kg

Where to use:
Deep consolidation of cementitious substrates with an unstable surface or with poor mechanical characteristics.
Consolidation of cementitious screeds which tend to have a crumbly surface due to hydration defects or a lack of binders.
Impregnation and anti-dust primer on cementitious surfaces.
Technical characteristics:
Prosfas is a blend of silicates in water solution with low viscosity and therefore high penetration properties.
It can penetrate to a depth of several centimetres and when dried, it improves the cohesion of cementitious surfaces.
Prosfas is ready-to-use and need not be diluted.
Application:
Pour the Prosfas on the surface with a sprinkler or pump and distribute it evenly with a broom, brush, or roller until it is completely absorbed.
Very friable or porous substrates may need more than one coat, in which case wait until the previous coat is dry.
