Step 8: Embed the heating system using leveling compound.

When the heating system is completely installed, apply a mixture of modified latex thinset compound over the entire heating system. Use a scrap board to spread and level the thinset to the top of the sleepers. Leveling compounds/thin-set/adhesive MUST contain latex compounds and capable of withstanding temperatures of up to 140°F (60°C) when used with underfloor electric heat systems.

Step 9: Install the hardwood flooring.

When the leveling compound has cured, install the hardwood flooring by attaching it to the wood sleepers only. Use caution not to damage the wires with your fasteners.

Step 10: Program the thermostat.

Program the thermostat to a maximum of 81°F (26.5°C) to avoid drying out the wood or causing warping. The thermostat must be regulated by a floor probe positioned between the heating cables. Note the Warmup 4IE thermostat does this automatically when selecting Wood Floors in the menu.

Attach the flooring to the wood sleepers only. Use caution not to damage the wires with your fasteners.

SnapStone Floating Tile Floors

IMG_0136Since 2005, SnapStone porcelain tile floors have been cutting installation time in half, thanks to its innovative interlocking tray system. Developed in Omaha, Nebraska, this patented floating tile floor system features a real porcelain tile permanently bonded to a polymer tray that “snaps” together with the tile tray next to it, eliminating the need for messy mortar, thinset and spacers. The SnapStone installation process is as easy as Prep, Snap, Grout. After ensuring the subfloor is flat, clean and dry, SnapStone can be installed and grouted within a day. A SnapStone floor installation requires only two things: a SnapStone tile and SnapStone’s flexible urethane grout. Perfect for the both the first time DIY’er and seasoned tile contractors alike, a SnapStone floor is suitable for most rooms in the home. Matching raw tile, bullnose and nine grout colors finish off the floor and |room as well. The SnapStone system can be installed over most existing subfloors, such as vinyl, hardwood, laminate or cement. It can also be laid over plywood in a new construction. With three tile collections and nearly 50 colors, you’re sure to find a beautiful floor for your home. Visit
