Now, there’s a better way thanks to the Raimondi Slant Ridge Notch Trowels for tile, the slanted and rounded trowel notch provides many advantages.
11″ Collapsible Ridge
Provide superior adhesive coverage
Anti-slip, comfortable rubber handle
When placing tile on adhesive spread with a slanted ridge, the ridges overlap and collapse (Domino effect) to provide superior adhesive coverage on the back of the tile vs. a standard notched trowel
Superior adhesive bonding also increase the efficiency of in floor heating systems since it removes air pockets which inhibit the transfer of heat to the flooring
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
Note: Dual profile 42 degrees to apply grout and 18 degrees angle to cut excess.
