Gout is a substance containing cement, sand, and sometimes epoxy, that is applied between the spaces of adjoining tiles to create a solid surface. Once dry, grout creates a hard surface that will endure for many years. One of the most important aspects of installing wall tile is to properly smooth out the grout during the application process. Smoothing out the tile grout gives the tile an attractive, professional-looking appearance. Smoothing out wall tile grout requires the use of special grout tools that are available at home improvement stores.

Apply the grout to the entire surface of the tiled wall using a grout float. Make sure to work the grout thoroughly into all crevices between the tiles.

Place a squeegee onto the surface of the tiles and position it so that it is diagonal to the grout lines. Pull the squeegee along the entire surface of the wall tile to remove any excess grout from the surface of the tile. Moving the squeegee in a diagonal direction ensures that the edges of the squeegee do not remove grout from the crevices of the tile.

Wait for 10 minutes to allow the grout to harden slightly.

Apply water to a sponge and squeeze out as much of the excess water as possible. Wipe the surface of the tiles gently with the sponge to remove any remaining grout and haze from the tiles. Rub in a circular motion so as not to remove grout from the crevices of the tile.

Rinse the sponge in clean water and rub the entire surface of the wall gently in a direction that is parallel to the grout lines. This helps to smooth out the edges of the grout so that they are slightly below the surface of the tile.

Insert a round finishing tile tool into one of the vertical grout lines near the edge of the tiled wall. Press down gently on the tool and drag it across the entire length of the grout line. Repeat the process with all remaining vertical and horizontal grout lines to smooth out the grout. Allow the grout to dry fully.
