Superior adhesive bonding also increases the efficiency of in floor heating systems since it removes air pockets which inhibit the transfer of heat to the flooring. Collapsible ridge provides maximum coverage is even more valuable in cases where bond failure is more prevalent such as: large format tile installations (8"x8" and up), high moisture areas such as pools & spas, and installations subject to extremes in temperature (i. e. exterior installations, or installations beneath large windows). The rounded shape of the notch reduces the chance of the adhesive "binding" and ripping away the ridges while troweling. The adhesive does not bind in the rounded corners of this notch so the adhesive ridges stay intact. Model # TR14FR Features: 1/4" Slanted Noth Trowel Anti-slip, comfortable rubber handle.
