Everbuild - Lumberjack MB Primer

Everbuild Lumberjack MB Primer is a one part, water free, moisture cure polyurethane liquid resin designed for treating concrete floors prior to laying wooden flooring. It is particularly useful for blocking capillary dampness in screeds when the residual moisture content is above that recommended for laying wooden floors (normally above 2.5% as measured by a carbide hygrometer).

Everbuild Lumberjack MB Primer will improve adhesion to difficult substrates such as anhydrite, and floors containing residual adhesive. Prevents moisture coming through the floor and twisting/cupping floorboards.

Coverage:Usage as a waterproofing membrane: Approx. 400 - 500g/m2

As an anti-dust primer: Approx. 100 - 200g/m2

Useful Benefits

Blocks moisture in damp screeds.
Acts as a primer for dusty screeds.
Helps bind the surface of weak screeds.
Forms an excellent patching mortar when mixed 1:9 by weight with sand for repairing cracks and holes in concrete floors.

Application

As a waterproofing membrane: Screeds must be free from oil, wax, dirt and must be adequately cured (minimum 4 weeks old). Apply at least two coats of Everbuild Lumberjack MB Primer by roller or brush at a 90 degree angle to each other allowing at least 4 hours drying between coats. Allow final coat to dry for 24 hours before covering is laid.

As an anti-dust primer or over existing adhesive residues: Remove as much adhesive as possible mechanically. Apply with a roller or brush in a single coat. Allow to dry for 24 hours. The high penetration helps bind the surface.
