Hi, just wondering if we could install Warm Board in an existing cottage that’s built on a concrete slab ? No floor yet, just concrete.
Absolutely! We recommend using split-drive anchors – those will be the best way to fasten. Checkout either our Warmboard-R or Warmboard-S install manuals for more information. https://www.warmboard.com/documents
Let us know if you have any other questions. Have a great day.
