Mapei Mapeproof Primer
10kg

Mapei Mapeproof Primer is a one-component, rapid drying PVDC based dispersion primer for suppressing residual moisture up to 4.5 CM-% (95% R.H.)

WHERE TO USE

Mapei 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)
