Lumberjack M.B 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). This primer will improve adhesion to difficult substrates such as anhydrite and floors containing residual adhesive.
