How to Grout a Shower

Before you get started:

  1. Follow the instruction’s recommended drying time—make sure mortar is dry and tile is firmly set.
  2. Remove all tile spacers.
  3. Tile should be clean and dry.
  4. Expansion joints (where tile meets adjacent walls, floors, or fixtures) should not be grouted. Instead, use caulk (see Caulking Section).

Installing Grout

TEC® Skill Set™ Power Grout™ or DesignColor™ Grout with Grout Boost® additive are highly recommended. Both of these solutions come in a wide array of designer colors and are stain-resistant and easy to use.

Refer to grout packaging for product capabilities, instructions and limitations.

Special Grouting Tips:
  • Many people pack the grout into the joints using the small end of the grout float (rather than the long end). This is an appropriate method, however, you should still use the long end to scrape excess grout off of the tile. Touch grout after 30 minutes. Grout should be firm, not soft. If there is no residue on your finger, grout is ready to clean.
  • Use a completely dry sponge for the clean-up steps, otherwise you will likely just be pulling grout out of the joints. First, use a circular motion to loosen grout haze and tool the joints.
  • For a second clean up, use the sponge to wipe the surface diagonally across the tiles and grout joints holding sponge flat to the surface. This should also help to smooth out the grout joints. Do not leave excess water pooled on the joints.
  • Clean the sponge frequently and wring out as much water as possible each time.
  • Replace the bucket of water frequently.
Installing Caulk

Once grout has cured, fill gaps at wall intersections, around tub, fiberglass or acrylic shower bases and fixtures fixtures with TEC® Invision® Ready To Use Caulk. The caulk is formulated to match grout colors.

  1. Apply bead along seam by drawing tube towards you. Maintain steady pressure on the tube.
  2. Lightly smooth bead with a wet finger or putty knife.
