How do I fix the insulated underlay to the subfloor?

Follow these steps to secure the Warmup insulated underlay to the subfloor:

  • Ensure that the base is clean and dry
  • Roll out the underlay, foil face down (you may secure edges using sections of duct tape)
  • Roll out the next section of underlay
  • Remove the protective film from the self adhesive overlap
  • Stick both rows together to create a damp proof situation
  • Repeat until floor area is covered.
