Bostik Hydroment Epoxy Mortar and Grout

Surface Preparation

Ensure tile is firmly set and mortar completely dry before grouting. Remove all spacers, debris or adhesive from tile joints. Application of a grout release agent may be necessary to prevent staining of tile. For best results, surface of tile should be at room temperature (70°F to 75°F). Do not apply at temperatures below 60°F, or above 85°F. Epoxy materials are affected by temperature variations. Cooler temperatures will decrease workability. Warmer temperatures will reduce sag resistance.

Application

Apply a thin coat of the properly mixed Hydroment Epoxy Mortar & Grout with the flat edge of trowel to achieve a good mechanical bond to the substrate. Comb additional mortar with the appropriate size notched trowel. If any evidence of skinning or setting occurs, re-comb mortar with notched trowel. Apply mortar to an area no greater than can be tiled in 20 to 30 minutes. Apply tile using a twisting motion into a fresh bed of mortar to ensure maximum contact and bond. Periodically check back of tile to ensure proper transfer (minimum 80% coverage

wet, plywood, or heavy or extra heavy service area applications— minimum 95% coverage). A finished mortar bed thickness of 3/32” to 1/8” is required.

Lightly moisten tile with clean, damp sponge before grouting. Spread grout over the face of the tile using a hard rubber epoxy grout float. Work grout back and forth at a 45° angle to the face of the tile to ensure complete filling of the joints. Remove excess grout by holding the rubber float at a 90° angle working diagonally across face of the tile.

Mixing

The Epoxy Mortar and Grout “Unit” is made up of a 6 gallon pail that contains powder aggregate, and two smaller containers which hold pre measured amounts of Epoxy Resin (Part A) and Epoxy Hardener (Part B). Pour the entire contents of the bag into the pail. Combine the liquid components and mix until there are no longer any streaks or lumps using a heavy-duty drill mixer or a commercially available 5-gallon pail mixer. Use a margin trowel or spatula to scrape the sides and bottom of the pail during the mixing process. Most problems with epoxy can be avoided by thorough mixing. Once no color streaks or lumps are EY566visible, continue to mix for an additional 2 to 3 minutes to ensure the epoxy is completely mixed.

Curing

Keep all foot traffic off the installation until tile is firmly set (approximately 12 hours). Set times are dependent upon temperature.

Keep all foot traffic off the installation until grout is firmly set (approximately 12 hours). Keep all heavy duty traffic off the installation until grout has an opportunity to fully set (approximately 72 hours).

Clean-Up

Clean all tools and equipment with soap and water. Do not allow material to dry on surface of tile.
