Floor Preparation
Subfloors previously covered in vinyl, cork or carpeting: all old
flooring and adhesive must be removed. If there is bitumen as a
damp proofing layer, it must be covered with a minimum 50 mm of
sand/cement screed or overboarded with 10 mm Warmup Insulation
Boards, taking care not to puncture the bitumen coating. The screed
must be fully cured and dry before proceeding. If using other damp
proofing or tanking systems, contact the manufacturer for advice.
For optimum performance it is recommended that you use Warmup®
Insulation Boards beneath Warmup StickyMat 3D™. The insulation
will improve the systems response to heating demand, saving energy
and reducing running costs.
