Wood flooring can also be installed utilizing the glue-down method. This is an especially popular method for solid parquet flooring installations on concrete sub-floors. Additionally, engineered wood flooring may use the glue-down method as well. A layer of mastic is placed onto the sub-floor using a trowel similar to those used in laying ceramic tile. The wood pieces are then laid on top of the glue and hammered into place using a rubber mallet and a protected 2x4 to create a level floor. Often the parquet floor will require sanding and re-finishing after the glue-down installation method due to the small size pieces. Denver Hardwood Flooring
Cupped floors, also called washboarding, develops gradually across the width of the wood strip where the edges of the hardwood planks raise up and the center of the board sinks down. The cause of cupped floors is a moisture imbalance where there is more water on the bottom side of the wood plank than on the top. The only cure is to balance the humidity levels in your home, and to give the surface time to return back to normal. After the floor has stabilized, you can have a professional sand it flat and re-finish it to perfection.
To fix a buckled floorboard, you need to be able to access the floor from below. The way to tackle this problem is to put weight on the buckled area from above — a cement block works well. Then install a 1 1/4-inch screw in the buckled flooring from below. Allow the screw to penetrate only halfway into the flooring, or it may come up through the finished surface. Driving the screw through the subfloor and into the flooring pulls the flooring down against the subfloor and gets rid of the buckled spot. Hardwood Floors
