How To Prepare Surface Before Laying New Vinyl Flooring Over Old? - February 23rd 2009
Q: I want to install (in a mud room) the Karndean vinyl flooring strips that look like hardwood. The existing sheet vinyl flooring is in good shape, so is it possible to lay the new vinyl floor directly over the old flooring without having to rip it out?

A: Most vinyl or linoleum floors have embossed patterns or designs of some kind, so it is not recommended to lay new flooring over the old without doing some proper preparations or the design may telegraph up through the face of the new floors.
For best results, wash the old floor with a de-waxing solution such as the Shell Busey Home Cleaning Formula. Next, using a flat trowel, apply a floor levelling compound, filling the embossed pattern areas. Allow 12 hours of curing time before laying your new vinyl flooring.
