STEP 3.6
Stone or Paver Application
ProMelt Mat: Begin laying out the mat and secure it onto the base with landscape fabric stakes or similar over the mat
tape every 2 feet or so. Make sure it is laid flat. Do not use metallic stakes or staples directly over the heating cable. Be
careful not to damage the heating cable.
ProMelt Cable: Secure plastic mounting cable ties to the gravel base, driving long nails or similar through the head of
the cable tie. These cable ties should be applied at the end of each run and at every 3 to 4 feet. Do not use metallic
cable ties as they may damage the cable.
Lay out the cable and secure with the cable ties.
Step 3.7
Ceramic or Stone Tile Applications
1) Dry-set or Latex-Portland Cement (thin-set) Mortar Application – For this application, the mat or cable is installed in
the slab, no less than 1.5" and no deeper than 2” below the top surface, so follow recommendations in section 3.4 for
mat or cable.
2) Cement Mortar or Thick-set Application – For this application, the cable will be installed in a minimum 1.25” thick
mortar bed above the structural slab.
ProMelt Mat: Begin laying out the mat and securing to the top of the slab by nailing through the tape every 2 feet or
so. Never strike the heating cable with a hammer. Minimum 1.25” mortar bed will be installed over the cables.
ProMelt Cable: Secure CableStrap to the surface of the slab, using nails spaced every 6 to 10 inches. CableStraps
should be placed at either end of the heated area for the initial layout. Additional straps should be placed every 3 to 4
feet to hold the cables in place during application of the thick-set mortar. Minimum 1.25” mortar bed will be installed
over the cables.
STEP 3.8 (ProMelt Mat Only)
If you need to cut and turn the mat, or fill odd areas, you may use scissors to carefully cut the tape holding the heating
cables. Heating cables should be secured at about 3 inches apart, and no less than 2 inches apart.
CAUTION: Be careful not to kink or sharply bend the heating cable.
A minimum bend radius of 1 inch should be maintained.
