How to Stick Grout on Tile

Clean off any dust, dirt or other residue from the installation of the tile to ensure the grout sticks well. Do this with a soft cloth, vacuum or a broom. Use a tile cleaner if the tile has been in place awhile before you attempt to apply grout.

Read the directions thoroughly on your powdered grout package. It is vital that you mix the correct ratio of powder to water to enable the grout to stick. Use a measuring cup to verify the amounts.

Mix the grout according to the label directions. Test the mixture to determine if it is ready for grouting. The goal is to scoop the grout out with a putty knife and hold it downward at an angle. If the grout drips off the putty knife, it is too thin. Remedy this by adding a small amount of powder, mixing and then testing the grout again. Once it resembles thick cake batter it is ready to spread. Add just a bit more water if it is too stiff to spread easily.

Spread a small amount of grout -- about half a cup -- into the tile with a grout float. Tilt it at a 30-degree angle.

Press the grout into the joints between the tiles with the grout float. Pack the grout in until you feel resistance and then scrape off the excess with the grout float held at a right angle on the surface. Repeat this process over all the tile.

Wipe off any haze or grout residue with a damp sponge when it is firm -- about five to 20 minutes. Wait about 15 to 20 minutes and wipe again. Rinse the sponge and wring it out often during the procedure.

Seal the hardened grout with a grout sealer after three days. This ensures the grout lasts a long time.
