How to grout a shower

Once you allowed the mortar to dry and the tile to sit for the time listed on its packaging, you're ready to move onto the next step: Grouting a shower.

Quick Tip

If grout sticks to the tile, pat it with sponge. Then, take a white nylon scrub pad and scrub the tile. It can remove grout easily.

Once your mortar is dry and your tile is firmly set, remove all of the spacers. Refer to your grout’s packaging for complete mixing and application instructions. Then, use a mixing attachment on a variable-speed drill at low speed to mix the grout according to the instructions on the packaging. If your tiles are stone or terra cotta, wet them before applying grout.

how to grout 1. Apply Grout Don't be afraid to really pack it into the joints. Many people find it easiest to pack the grout into the joints using the small end of the grout float, rather than the long edge. This method works just fine, but remember to use the long end of the float to scrape off excess grout after the joints are filled.

Apply the grout with a grout float, working the grout into the narrow spaces and filling all the joints completely. Work at your own pace and direction that seems natural to you. Holding the grout float at a 45-degree angle to the tile, move it diagonally across the shower floor or ƒif shower wall.

If no grout sticks to your finger, then immediately begin the next phase of grouting. After the grout sets – typically for about 10 minutes – you’ll need to begin cleanup. Slightly dampen a large, small-pore, synthetic sponge. The sponge should not be wet, so make sure you wring it out well. Lightly wipe the sponge across the tile surface, avoiding removing too much grout. Also use the sponge to smooth out the grout joints. If grout pulls out of the joints, you need to allow additional setting time.

4. Wipe away grout haze grouting+tile Wipe away any remaining grout with the sponge and let the grout cure for the required time. Refer to the grout packaging for appropriate cure time. Grout in submerged areas, like showers, take longer to cure. TEC Power Grout RTU cures within 7 days, which means that you can use your shower within a week after the installation is complete. This is a faster cure time than competitors.
