Lowe's home improvement expert Mike Kraft is back again to show to help us install laminate wood flooring in our homes. It has been assumed that proper sub-floor preparation has been done. All the tools, equipment, and materials are gone over in detail for your safety. Proper tests for moisture are described which is very important when dealing with concrete. Laminate floors are called "floating floors" because they are not physically joined to the sub-floor and can be installed over many different types of sub-flooring.
