Marshalltown Square Notched Tile Trowel 16X4 (711SD) is a 16 x 4 inch tile-setting trowel with 1/2 x 1/2 x 1/2-inch square notches on two sides — for spreading mortar at the right thickness for backerboard, plywood, and concrete substrate tile installs. The blade is forged from high-carbon steel and tempered for production-grade durability — the steel takes a working edge, holds shape under repeated impact with brick or block, and resists the corrosion that comes from constant contact with wet mortar.
This trowel handles tile installation work — the square notches set the consistent mortar bed thickness that prevents lippage and bond failure. Marshalltown trowels are the trade-default tool that every working masonry pro and concrete finisher learns on — the brand’s been in tradesman’s hands long enough that union apprentices get one in their first kit. Daily working use; oil the blade after a long pour or wet day to extend service life.
