primer FP•31

water-based acrylic primer for sealing cementitious substrates

Acrylic primer in water dispersion, for stabilizing and sealing cementitious substrates prior to the application of self-levelling compounds (FLOW 1•10 RAPID, FLOW 3•30 ECO•RAPID, FLOW 5•50 RAPID) and levelling floor screeds.
It penetrates deeply in the substrate while at the same time it seals the surface.
It improves adhesion mortar and substrate while significantly reduces the formation of bubbles in the levelling compounds.
It shows very low emission of Volatile Organic Compounds (VOC).


It is used for the stabilization and sealing of cementitious substrates prior the application of self-levelling compounds, industrial floors and levelling floor screeds.


Approximately 0.1-0.2 kg/m2 depending on the dilution rate and the surface’s absorbency.


Available in:

  • 5kg and 20kg plastic containers

Storage: 12 months from production date, if stored in original, sealed container, protected from direct sunlight and frost.
