Installation Instructions Baseboard Installation
  1. Split the first row of baseboards in half lengthwise and place the cut edges against the wall.
  2. Lay the first board with its cut edges in the corner, then position the rest end-to-end along the wall.
  3. Leave an 8-10mm expansion gap around the perimeter and any fixed objects.
  4. Continue laying the second row, staggering joints for added stability.
  5. Keep the protective film on the adhesive side until the top boards are ready to be placed.
Top Board Installation
  1. Lay the top boards in the same direction as the baseboards with the adhesive side facing down.
  2. Position the first board in the corner, overlapping both the first and second rows of baseboards.
  3. Peel back only the required amount of protective film to expose the adhesive surface.
  4. Secure the board by tapping it down with a rubber mallet, ensuring tight joints.
  5. Stagger the next rows by alternating full and half-length boards for a gap-free finish.
Final Floor Finish
  • Once installed, glue your final floor covering onto the boards or place it freely on top.
  • Test the foil heater(s) and floor sensor before laying the final floor covering to ensure no damage occurred during installation.

Important Notes

  • Not suitable for wet areas: Do not use in bathrooms, wet rooms, or en-suites as MDF will expand when exposed to moisture.
  • For wet areas, use an underfloor heating mat with a self-leveling compound.
  • Ensure an expansion gap of 8-10mm (16mm at door openings) when continuing into adjoining areas.

Upgrade your underfloor heating system with the Heat-Pak® Dual Overlay System – offering unmatched stability, efficiency, and ease of installation for a comfortable and long-lasting floor finish.
