Primer
Moisture Barrier is a versatile, single-component polyurethane primer designed as a roll-on moisture membrane to reduce vapor transmission on both absorbent and non-absorbent subfloors, including gypsum-based underlayment. In addition to serving as an anti-dust agent, surface consolidator, and Damp-Proof Membrane (DPM) for cement, it provides effective anti-dust treatment for anhydrite and heated subfloors. This polyurethane reactive primer is fully compatible with the entire Forteko system.

Directions for Use

1. Subfloor Preparation
Clean the subfloor thoroughly, removing all oil, grease, wax, paint, or other contaminants. Ensure the subfloor is crack-free. Concrete must be porous (according to per ASTM F3191) so P1000 can penetrate.

2. Moisture Test Subfloor
For concrete floors ensure concrete is under 98% rH with no hydrostatic pressure. **Do not apply on any concrete with hydrostatic pressure. For projects with radiant heat P1000 works up to 85% rH.

3a. Subfloor Preparation - Wood
Apply a single coat of P1000 with a 4-6mm roller. Distribute evenly, using approximately 2.5g to 1000sq. ft. to form a thin, uniform film. Avoid pooling, as this can delay drying and affect adhesive performance.

3b. Subfloor Preparation - Concrete
Apply one or two coats of P1000 with a 4-6mm roller. Distribute evenly, using approximately 2.5g to 1000sq. ft. to form a thin, uniform film. Avoid pooling, as this can delay drying and affecting adhesive performance. If doing 2 coats they should go perpendicular to each other for best coverage. Wait 1-2 hours prior to applying the 2nd hot coat.*Only use on slabs that are cured (30-60 days)

4. Bonding Process
Begin bonding (applying adhesive) 4-6 hours (If humidity is low, preferably wait overnight) after applying P1000, but no later 5 days. Use only reactive adhesives, such as Forteko Trowel Glue T200 or Forteko Sausage Glue S30. If over 5 days, lightly buff for proper adhesion.

5. Product Handling
Do not return leftover product to the original container. Dispose of excess material responsibly.

Gypcrete Usage
For gypcrete P1000 primer can be applied, we suggest conducting a test to determine if a second coat is necessary for additional reinforcement. We recommend testing because gypcrete can be quite porous, which may require extra strengthening, and the installed psi could be lower than the specified value. We require 3 tests on gypcrete prior to using primer and glue on gypcrete.
Important Information
Temperature and Humidity Conditions
Ensure the floor temperature is at least +15°C (59°F) and the room temperature is at least +18°C (65°F). Maintain room humidity between 40% and 65%, with a maximum of 75%. The provided guidelines are based on conditions of approximately 20°C (69°F) and 50% relative humidity.
Compatibility and Restrictions
Do not apply P1000 on floor coverings such as PVC, CV, rubber, or linoleum.
Humidity and Application Quantities
Low humidity or excessive application quantities may extend the drying time of the primer. Confirm the surface is no longer tacky before proceeding with additional work.
