SPC flooring can be installed over concrete, wood subfloors and most existing hard-surface floor coverings.

Unacceptable floor coverings include Carpet (any type), foam underlayment, cushioned-back vinyl, rubber, cork, laminates, free-floating floors, and wooden floors over concrete.

All subfloors must be dry, clean (swept and vacuumed of any debris). Use floor leveling compound if necessaryto achieve the desired flatness. The height difference tolerance is no more than ±1mm.

To install over an existing hard-surface flooring (ceramic tile, resilient tile, etc.) check to see it is well bonded tothe subfloor and flat. Apply cement based leveling compound to flatten surface. Heavily cushioned vinyl flooringor vinyl flooring consisting of multiple layers is not a suitable subfloor for installation. Do not sand existingflooring as it may contain asbestos. Take proper precautions and contact an asbestos abatement company toremove old flooring.

Concrete subfloors must be fully cured for a minimum of 60 days prior to SPC flooring installation and must be tested for moisture. Concrete moisture vapor emissions should not exceed 8lbs (ASTM F1869) or 90%RH (ASTMF2170) with a pH limit of 9. For installations outside of this range, it’s required to use a minimum 6 mil poly film (water barrier sheet/moisture barrier) between concrete and ground. Subfloor moisture prevention limits the potential growth of harmful bacteria and mold.

To ensure optimal installation and performance of your flooring, it's crucial to maintain a suitable subfloor temperature. For all subfloor types, including concrete and wood, the ideal temperature range is between 60°F and 80°F. It's essential to avoid exceeding 112°F, as higher temperatures can negatively impact the flooring's installation and long-term durability.
