Description
Is this the right product?
Use it for: One-part (no mixing), water-based, textured moisture-control membrane, pH blocker and self-leveller primer for indoor concrete, rolled on in two coats. Handles slabs up to 25 lbs MVER (ASTM F1869), 100% RH (ASTM F2170) and pH 14, and no second primer is needed before a self-leveller. Also primes cement or wood before a self-leveller. Goes over absorbent concrete on, above or below grade at least 7 days old (CSP 1 or more), cement-based self-levellers and patches, and (as a sealer or primer only) exterior-grade plywood and other approved wood underlayments. Tinted burgundy so you can see coverage. Patches, adhesives or self-levellers after 1 to 2 hours. Meets the performance requirements of ASTM F3010 and complies with ASTM F3513.
Not for: Outdoors, standing water, non-porous surfaces, slabs over 25 lbs MVER, 100% RH or pH 14, or slabs with hydrostatic moisture or alkali-silica reaction problems. Not over anything containing asbestos. It is a moisture barrier only: Mapei does not warrant it against cracks or debonding from later slab movement, so cracks and joints need their own treatment. Substrate between 10°C and 32°C and at least 2.8°C (5°F) above the dew point.
Use instead: Sealing old carpet or cutback adhesive residue, or blocking pet urine stains and odours: Planiseal MSP. A two-part, 100%-solids epoxy barrier for new slabs from 5 days old: Planiseal VS.
Damp slab holding up your flooring job? Planiseal Max is a moisture barrier and textured primer in one: two rolled coats protect the flooring from slab moisture and high pH, and a Mapei self-leveller can go straight on top with no second primer.
Rated for slabs up to 25 lbs MVER, 100% RH and pH 14, on, above or below grade. It is one-part and water-based, the first coat dries in about 30 minutes, and it is tinted burgundy so you can see where you've rolled.
15.1 L (4 gal) pail · Coverage: about 500 to 600 sq ft per pail (two coats) · Up to 25 lbs MVER and 100% RH · ASTM F3010
Check that the slab is absorbent first: water droplets should darken or soak in, not bead. Apply with a 3/8" nap roller, with the second coat rolled perpendicular to the first.
