Product Information

Use a hose sprayer to clean a trowel. And immediately after that, use a clean sponge with some water to finish cleaning.

In general, pushing in the mortar using the flat side of the trowel is very important for a good chemical bond. You may add more mortar to the substrate and spread the mortar in straight lines, all going in the same direction. This will help provide better spreading of the mortar. The size and spacing of the trowel teeth are the basis to measure tile trowel size. This tells you how much adhesive the trowel will leave on the substrate when you spread it out. The trowel’s tooth shape and spacing determines how much adhesive is sandwiched between the tile and substrate once the tile is fully installed.In general, the number of trowels required for every project varies. It mainly depends on the number of various size tiles you will be installing and how much preparation is required. ● How should one clean a trowel? Take a ¼ x ¼ inch square notch trowel, for example. One might think that since the notch is ¼ inch tall and ¼ inch wide that compressing the tile simply fills in the space. Therefore, half of the ¼ inch high notch fills in the space leaving it ⅛ inch high. A V-notch trowel has V-shaped edges. This is the trowel to use when installing mosaic tile as it leaves the least amount of thin-set on the installation substrate. I’ve even seen another blog use this very calculation but it isn’t correct. They don’t factor in that you are holding the trowel at an angle and not straight up & down. Therefore the mortar that is combed onto the floor isn’t ¼ inch high.

A U-shaped ridge, on the other hand, spreads OUT when embedding a tile into the bed. Pushing a tile into the bed of rounded ridges causes the ridge of adhesive to spread out, from the bottom, with less possibility of trapping air. Which trowel size to use?

In general, use a trowel size that ensures at least a 85% adhesive coverage for a dry area. This is the amount of area under the tile that is covered by the adhesive. And a 95% minimum coverage for a wet area (bath surrounds, showers, etc.). Long-Lasting: Using the correct notch size and shape will help your tiles last longer. Larger, heavier tiles need notches that leave behind a good amount of thin-set, while smaller, lighter tiles do not. U- Notch Trowel ¼” x ¼” – for 4″ x4″ up to 8″ x8″ tile. This is the preferred trowel for those who want a lighter spread for floor tile OR a heavy spread for wall tile. Whether you are installing small mosaic tiles, subway tiles, or large natural stone tiles, notched trowels are essential tools for setting tiles into place. Notched trowels scoop thin-set, a cement-based mortar adhesive, and spread it over floors and walls. The distinctive notches on the sides of the trowel create an even base of ridged mortar. When a tile is placed, the mortar compresses to provide a complete bond between the tile and the wall/floor. This bond will keep tile in place for years.
