What tool is commonly used to remove excess grout from tile surfaces?

The commonly used tool for removing excess grout from tile surfaces is a grout float or sponge. A grout float is specifically designed to apply grout effectively into the joints between tiles and also has a flat surface that allows for easy scraping away of any extra grout from the tile surface after the filling process. The slightly beveled edge of the grout float is particularly effective in wiping off the excess while ensuring the grout fills the joints well.

Additionally, a sponge is often used in combination with the grout float to gently clean the tiles without disturbing the grout in the joints. The sponge can be dampened to assist in removing the grout residue without scratching the tile surface. Therefore, using either or both tools ensures a clean finish and helps maintain the aesthetic of the tiled surface.
