Solvent-free hygro-hardening single-component polyurethane primer with ultra-low emission of volatile organic compounds (VOC), for waterproofing cement-based screeds. If a cement-based smoothing treatment must be carried out after F.24 POLIPRIMER has been applied, dust the freshly treated surface with fine quartz so as to create an adequate bond and remove all the loose excess after 36 hours.
Suitable for:
• surface strengthening treatment for both cement- and anhydrite-based screeds, also heated screeds.
• Waterproofing cement-based screeds with up to 5% residual humidity before laying wooden floors.
PROFESSIONAL USE.

Coverage
0.2-0.4 kg/m2 per coat, depending on the porosity of the substrate.
