Bostik Hydroment 1900 Epoxy-Modified Grout and Mortar Admixture

Surface Preparation

USE AS A SETTING SYSTEM:SURFACE PREPARATION: All surfaces must be clean, dry and smooth

free of voids, projections, loose materials, oil, grease, sealers, curing compounds, waxes and all other surface contaminants that may inhibit proper bond. For best results, surface, mortar, and tile should be at room temperature (70°F to 75°F). Do not apply at temperatures below 60°F, or above 85°F.

USE AS A GROUTING SYSTEM: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.

Application

Apply a thin coat of properly mixed Hydroment 1900 Modified Mortar with the flat edge of trowel to achieve a good mechanical bond to the substrate. Comb additional mortar with the appropriate size notch 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 (interior applications-minimum 80% coverage

exterior, wet, or plywood applications--minimum 95% coverage). A finished mortar bed thickness of 3/32" to 1/8" is required.

See Technical Data Sheet for more info.

Lightly moisten tile with clean, damp sponge before grouting. Spread grout over the face of the tile using a rubber 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 the face of the tile.

Mixing

Using a slow speed mixer (<150 rpm), separately mix 1900 Emulsion Resin (Part A) and then 1900 Hardener (Part B). Mix Resin (Part A) with equal volume of Hardener (Part B) until completely and thoroughly mixed. Slowly add required amount of Hydroment Sanded Ceramic Tile Grout (25 lbs. for Single Unit

50 lbs. for Double Unit

250 lbs. for Industrial Unit) and mix until a smooth, uniform consistency is achieved. Allow mixture to stand 15 minutes, and re-mix prior to application. Do not retemper by adding more liquid.

Curing

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

Clean-Up

USE AS A SETTING SYSTEM: Clean all tools and equipment with soap and water. Do not allow material to dry on surface of tile.

USE AS A GROUTING SYSTEM: FINAL CLEAN UP: Depending on humidity and temperature, begin final clean up approximately 1 hour after initial cleaning. Using a damp nylon scrub pad (i.e.: 3M Doodlebug®), wipe diagonally across the face of the tile. Change water and rinse pad frequently to minimize the build up of grout haze. Never use acid cleaners as they may result in irreversible damage to the grout or tile.
