HYDROPRIMER K5 Casati is a water-soluble coarse-grained Pigmented Primer. Suitable for mineral substrates in general and plasterboard. External / internal use.
Hydroprimer K5 by Casati is a coarse-grained pigmented fixative insulating primer, with good adhesion characteristics even on difficult substrates (eg old paints as long as they are well anchored to the building substrate). Hydroprimer K5 is ideal for new civil plasters, cracked civil plasters, plasterboard, cement or concrete products and suitably prepared coatings. It is an extremely breathable base coat: its application on new substrates does not affect their natural permeability to water vapor.
