Armstrong Flooring products may be installed over a single layer of existing resilient flooring when the proper installation system is used for the new product and the existing resilient flooring meets the proper conditions. Armstrong Flooring does not recommend installing new flooring over existing rubber or slip retardant floors.
Existing Resilient Flooring Conditions:
- Not textured or embossed enough to show through the new installation.
- Only a single layer of flooring.
- Fully and firmly bonded on an approved subfloor and underlayment.
- Waxes, polishes and other finishes must be properly removed with a recommended floor stripper. For existing linoleum, the stripper should not exceed a pH of 10.
- Indentations or damaged areas must be replaced or repaired.
NOTE: The responsibility for determining if the old resilient flooring is well-bonded to the subfloor, and is not textured or embossed enough to show through the final installation rests with the installer. Installations over existing resilient flooring may be more susceptible to indentations.
