One of the best ways to prevent job-site accidents when installing WarmWalk radiant floor heating system over tile is to use this plastic trowel to minimize the risk of nicking the heating wire - a common accident when using metal trowels. Optionally, use the flat side of the trowel to float a skim-coat over the mat. Use of this 3/8 in. notched plastic trowel also assures the minimum recommended amount of thin-set mortar is applied over the heating mat.

  • 3/8 in. x 3/8 in. square notch helps insure adequate thin-set coverage over floor heating mat
  • Light weight material makes the job seem easier
  • Cleans easily with water
  • Will not rust

Rated 5.0 out of 5.0 by Great product This is a great product. I put heated flooring in the self leveling underlayment and the wires come up in some areas. Using the plastic trowel was great am very easy to use. I was comfortable with spreading mortar and didn't worry about damaging the wire. Tile looks great March 18, 2014
Rated 5.0 out of 5.0 by Heated Floor Trowel This is the trowel you need for heated floor installation. Too bad the store doesn't carry it. The plastic construction is what will keep the heated floor wire from getting damaged when installing the flooring. March 20, 2014
