f o o r r p e e p m i a r M P One-component, rapid drying PVDC based dispersion primer for suppressing residual moisture up to 4.5 CM-% (95% R.H.)
WHERE TO USE Mapeproof Primer is a one component, ready to use system which dries rapidly to provide a waterproof surface membrane; it impedes the passage of residual construction moisture from affecting subsequent floorcovering installations, therefore allowing early installation of floorcoverings. Some application examples • For damp-proofing cement based, moisture-resistant, non-heated substrates where residual moisture content values are up to 4.5 CM-%, before the application of levelling compounds. • For insulating residual construction moisture where relative humidity values are up to 95%. (ASTM F2170)
– no primer or broadcasted sand is required with subsequent levelling compounds; – complies with ASTM D 1308-87 standard for the resistance to urine; – can be resealed and stored with no particular precautions for future use; – not inflammable; – EMICODE EC1 Plus (very low emission); – Blauer Engel - DE-UZ 113. RECOMMENDATIONS • Apply Mapeproof Primer only on internal flooring.
TECHNICAL CHARACTERISTICS Mapeproof Primer is a one component, ready to use polyvinylidene chloride based dispersion primer which dries rapidly to provide a waterproof surface membrane.
• Do not use over anhydrite or other gypsum/sulphate based substrates.
Product properties:
• Not suitable for use on substrates with underfloor heating.
– ready for use; – no mixing is required; – easy to apply by roller; – colour pigmented to aid coverage uniformity; – fast drying; – low consumption/high coverage;
• Do not use on substrates subject to rising damp.
APPLICATION PROCEDURE Preparation of the substrate Substrates must be uniformly sound, free of dust, loose particles, cracks, paint, wax, oil, rust or other products that can interfere with bonding. Screeds and concrete bases over base-ground must be provided with a structural damp proof membrane. The residual moisture content of non-heated cement
