How do I secure the WarmWire strap to a slab?
Drilling holes and fastening the strap with screws is an approved method. If you have backerboard over plywood, you can use nails or screws to hold the strap. The fastest and easiest way, however, is to spray the back of the strap with high-strength spray adhesive. Hot glue is a good alternative to spray adhesive. We also include double-sided tape in our kits (or you can purchase it separately), and this works well, especially over concrete.
