Installing SPC Over Old Tile, Hardwood or Concrete in Older Rhode Island Homes

Rhode Island has some of the oldest housing in the country, and fixer-uppers here often come with several decades of flooring stacked on top of each other. Good news: rigid-core SPC can often go right over what is there, which saves demo time and disposal fees.

Over ceramic tile: usually yes

If the tile is well stuck down and not cracked or hollow-sounding, you can float over it. Fill grout lines wider than 1/4″ with a patch so they do not telegraph through the plank.

Over hardwood: usually yes

Nail down any loose or squeaky boards and sand high spots. Old wood floors are often out of level near outside walls, so check with a long straight edge.

Over sheet vinyl or linoleum: yes, if it is flat

One layer of well-bonded sheet vinyl is fine to cover. Do not float over cushioned vinyl; it is too soft.

Over carpet: never

Carpet and pad always come out. They are too soft for click joints and trap moisture.

Over concrete: yes, with a vapor barrier

Put down 6 mil poly first, especially in basements and slab-on-grade additions.

Built before 1978? Old paint, some old tiles and old adhesives can contain lead or asbestos. Floating over them without sanding or grinding is often the safest route. Check Rhode Island’s lead-safe rules before you disturb old surfaces in a rental.

Watch the door heights

Adding a new layer raises the floor. Undercut door casings with a jamb saw and check that doors still swing, especially with thicker planks like 8mm Citadel.
