Selecting the right trowel is a critical part of tile preparation because it dictates the amount of mortar deposited under the tile. Manufacturers provide specific recommendations based on tile dimensions; for instance, small mosaics use a V-notch trowel, while large-format tiles require large square or notched trowels, such as a 1/2-inch by 1/2-inch square notch. The goal is to apply enough mortar to achieve the required coverage without excessive squeeze-out at the grout lines. If the trowel is too small, there won't be enough mortar to support the tile, leading to potential cracking. If the trowel is too large, the excess mortar may push through the grout lines, making installation difficult and potentially affecting the final appearance of the grout. Furthermore, the flatness of the subfloor plays a role; an uneven subfloor may necessitate a larger trowel to fill dips and ensure the tiles remain level. Always consult the technical specifications of both the tile and the mortar to ensure the chosen notch depth complies with industry standards for the specific application.
