What is floor preparation and why is it important?
Floor preparation is just as important as installing the floor itself. Realistically it should be considered the most important. Unfortunately many installers don’t place the emphasis as they should. Neglecting floor preparation will often result in failure. It may not be apparent immediately, but over time, hardwood floors will loosen from the sub floor and begin to creak, pop, or have hollow sounds. Methods to correct before the actual installation are several. With wood sub floors minor high spots can be sanded down and low spots filled with an appropriate compound suitable for nailing hardwood floors. Concrete floors will have to be chipped or grinded if there are severe high areas. Low spots filled with a compound that cures quickly.
