How to Epoxy Sanded Grout

Grout fills in the spaces between tiles.

Epoxy grout is made of epoxy resins and an additional hardener. This grout variety is stain proof, water proof, and resists most chemicals. It sets quickly and comes unmixed, so it can be stored on a shelf for any amount of time. Epoxy grout comes in both sanded and unsanded varieties. Homeowners should always use the sanded variety when applying grout to tile joints that are 1/8 inch or larger. When working with epoxy grout, wear protective gloves.

Things You'll Need

• Bucket
• Grout mixer
• Grout float
• Damp sponge
• Dry towel
• Epoxy film remover

Instructions

1. Empty the two parts of the epoxy grout into a clean bucket, according to the package directions. Mix the epoxy components together with a mechanical grout mixer, until it has the consistency of a thick paste.

2. Scoop out the grout with a hard epoxy grout float and pull the float across the tiles on their diagonal. Hold the float at a 45-degree angle to force the grout into the joints. Continue filling the joints until you have completed a five-foot square area.

3. Scrape up the excess grout in the five-foot area by holding the float perpendicular to the floor. Pull the float across the tiles in a direction perpendicular to the one you used when applying the grout.

4. Wipe the grouted tiles with a damp sponge. Rinse the sponge repeatedly as you clean the tiles.

5. Repeat the grouting, scraping of the excess, and wiping down of the tiles, working in five foot sections at a time. Continue until you have grouted the entire area.

6. Let the grout dry according to the package directions. Wipe the floor with a dry, lint-free cloth. If there is any epoxy film on the tiles, remove it with an epoxy film remover.
