How to Seal Epoxy Grout
Epoxy grout is the best type of grout for use with tiles. It is the most expensive kind of grout, and is not as readily available as other types. It is not as porous as other types of grout material, but it should be sealed in the same way as other grout in order to increase its water resistance.
In order to seal epoxy grout, you need to apply an epoxy grout sealant. The process for accomplishing this task can be found in this article, along with the tools and materials needed to complete this task.
Step 1 - Purchase Materials for Sealing the Epoxy Grout
You need to purchase the epoxy grout, epoxy grout sealant, and other materials needed for the job. You may need to order the epoxy grout and the epoxy grout sealant online if you are unable to find it at the home improvement center.
Step 2 - Clean the Tile
Before you grout the tile, take a wet, soft rag and clean the tile in order to remove any of the tile cement that ended up on the tiles. Wipe the tiles completely and make sure that they are completely dry before you begin the process of applying the epoxy grout.
Step 3 - Apply the Grout to the Tiles
Prepare a mixture of the epoxy grout according to the instructions on the package. With a small amount of the epoxy grout on hand, use the grout float to work the grout into the tile seams. Once you have completed the grouting, let the wall dry for 24 to 48 hours, depending on the directions for the epoxy grout. Clean the tile when it has dried. This will give you an area in which to apply the epoxy grout sealant to the walls.
Step 4 - Apply the Epoxy Grout Sealant
With the tile wall cleaned and dried, apply the epoxy grout sealant. Working with small amounts of sealant, use a grout float to apply the epoxy grout sealant on the grout lines that you created in Step 3. Cover the entire tile wall with the sealant and allow it to dry before continuing to the final step.
Step 5 - Clean the Tiles
With the epoxy grout sealant applied to the walls and dried, clean the tile wall using a wet rag. Wipe the wall completely to remove any of the remaining excess material that was applied during the grout. This will complete the seal of your epoxy grout.
