ISOMAT PRIMER PU 100 FOR PU 510 17KG

ISOMAT PRIMER-PU 100 is a single-component, solvent-based polyurethane primer for preparing porous substrates before applying compatible polyurethane waterproofing membranes such as ISOFLEX-PU systems. It penetrates deeply into surfaces such as concrete, cement screeds and wood, helping strengthen the substrate and improve membrane adhesion.

The transparent primer creates an effective bonding layer between the surface and the waterproofing system, supporting better durability and long-term performance. It is easy to apply, fast drying and suitable for professional waterproofing preparation on roofs, terraces and other compatible building surfaces.
