Prosfas Consolidating Compound For Screeds 25kg

Solvent-free, silicatebased consolidator for cementitious substrates, with a high penetration capacity


Surfaces of screeds can be repaired using 0.5 to 0.7 kg/m2 of Prosfas but very porous surfaces may require four to six times as much

PACKAGING  25 kg drums.

Availability: In stock


Prosfas is used for the following: • 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. RECOMMENDATIONS • Do not use Prosfas on non-absorbent or wet surfaces. • Do not use on Mapecem or Mapecem Pronto screeds. • Do not use on anhydrite surfaces. • Do not dilute with water or solvents. • Immediately clean up any drops of Prosfas from ceramic tile, glass, marble, and metal surfaces.


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. Do not allow pools of excess Prosfas to accumulate because they form a shiny anti-adhesive film. To prevent the film from forming, sprinkle sand over the last coat of Prosfas and remove the excess sand when dry. Proceed with levelling or installation of flooring after making sure the surface is dry. Drying time varies with the amount of product used, and ambient temperature and humidity. The recommended application temperature is from +5°C to +35°C.


Hands, tools and surfaces in contact with Prosfas must be cleaned immediately with abundant water. Once it hardens, removal is difficult and can only be done mechanically.
