Question vinyl installation questions

Is it a common practice to install the vinyl floor over old floor? or should I remove the old before I install the new?

Also, if the seams in the old flooring is warped and is peeling back...does it mean that i have to remove the old flooring indefintely in order to maintain a smooth surface to laydown the new flooring?

Also can i get a clearification about the gap between the flooring and wall? I am suppose to undercut the flooring to leave an 1/8" gap to be hidden by the molding in order to compensate for the expansion and contraction of the vinyl?

Installing vinyl over vinyl

Most vinyl manufacturers recommend a new plywood underlayment in order to maintain product warranties. Installing new vinyl over old that is not firmly attached or is cushion backed may lead to failure of the new vinyl. If the old vinyl is curled, badly torn, loose, then it should be removed or covered over with a new underlayment. If the vinyl is rigid (not cushion backed) and securely attached, then it is possible to install new vinyl over old. Embossed vinyl will require coating with a leveling product in order to provide a super smooth surface for the new vinyl.

Go to for helpful installation information.

Older vinyls and adhesives used before the 1980s may contain asbestos. These should not be disturbed. They are covered over with a new plywood underlayment.
