If you're looking at installing a hardwood floor, and require hardness and stability in the flooring used, this video is for you. Master builder Matt Risinger and EJ Rathburn of Hardwood Designs, the sole source of the flooring from the log to the job site, discuss installing whole-house mesquite flooring. EJ explains how mesquite is chosen for its hardness, twice that of most commonly used oak, and has such stability, it can actually be glued to the subfloor rather than nailed down. EJ also discusses board length based on how mesquite grows and how rich and deep the color is on this flooring, once stained. Because there are natural imperfections in the wood that will need to be filled, the video shows how to use epoxy and chalk as a filler. Risinger gives a builder's perspective on where to install the floor given its longevity of approximately 70 years, in a home where remodels may be done several times during that period. Post-installation of the boards, EJ walks us through the finishing of the flooring. Three passes with a sander takes care of any unevenness that may be due to the subfloor. A quick coat of stain is buffed onto the floor and the next day, the first coat of an oil-based urethane, with a second applied when all construction on the house is finished. See the result of the flooring installation. Not only does the floor hold up with outstanding hardness and stability, the finished flooring is beautiful.
