Nice toolNice when tiling over the mats as you worry less using this plastic trowel rather than a sharp metal trowel. For $15 there's no reason to chance it using a metal trowel.
Good Tool For A DIYThis tool took all of the worry out of installing floor tile over a warm wire installation.
Great toolBought this trowel with heat mat kit. Tile installer was very pleased by how nice of a job it did spreading the thin set over the mat. It is a must when installing tile over a heat mat system.
