Frequently asked questions

Q: Can carpet underlay be used?
A: Yes, carpet underlay can be used on top of 10mm MDF as per Overlay Lite instructions.
Q: Will tile adhesive secure the tiles to the Overlay and if so will it need to be a flexible adhesive?
A: Yes, as with Overlay instructions, use a sealant with flexible adhesive and grout.
Q: Would I need to remove and then replace the skirting board around the underfloor heating?
A: This can be done but is not essential and depends on how high you want your skirting board.
Q: If I am using wooden flooring e.g. laminate/solid wood/engineered wood, will I need to leave an expansion gap?
A: An expansion gap does not need to be left for either the Overlay or the Overlay Lite panels so they can be laid next to a wall.
