Product Description
Wakol PU 280 Moisture Barrier
One-component waterproof primer for priming porous/absorbent and non-porous subfloors and for rigidifying soft subfloor surfaces. WAKOL PU 280 Moisture Barrier is a premium moisture barrier for "green" concrete slabs and for concrete and offers two levels of moisture protection.
One component premium moisture barrier and primer for:
- Porous/absorbent subfloors
- Non-porous/non-absorbent subfloors
- Solidifying soft subfloor surfaces (including gypsum and lightweight concrete)
- “Green” concrete slabs
- Encapsulating non-water-soluble adhesive residue (including “cut-back”)
- Primer / moisture retarder on plywood substrates
- Concrete with residual moisture prior to installation of flooring
Coverage and Application
- One coat will block moisture in concrete slabs up to12 lbs. /1000 sq. ft. / 24 hour (ASTM F 1869) or up to 90 % rH (ASTM F 2170-02)
- Two coats will block moisture in concrete slabs up to 18 lbs. / 1000 sq. ft. / 24 hours (ASTM F 1869) or up to 98 % rH (ASTM F 2170-02). No moisture test required: The concrete must be surface dry, at least 28 days old and must have an intact structural waterproofing membrane beneath the slab.
- Two Coats can also be used to block moisture up to 6 lbs. / 1000 sq. ft. / 24 hours (ASTM F 1869) or up to 85 % rH (ASTM F 2170-02) over-radiant heat.
- Jobsite conditions must meet ASTM, NWFA, or RFCI Guidelines. Doors and windows must be installed and the HVAC running to simulate the living environment climate conditions at work site: 60°F to 75°F / 15°C to 24°C, 40% to 65% relative humidity. Acclimate materials during cold periods properly.
