• excellent workability
• convenient/easy to use

• superior compressive strength
• superior flexural and tensile strengths
• superior chemical resistance (to dilute acids, household foods and cleaners, food waste, de-icing salts, gasoline, diesel fuel and other hydrocarbon solvents)
• excellent workability
• easy clean-up
• can be used with all Hydroment grout colors (except white)
• Hydroment CTG, when Mixed with Hydroment 1900, will appear darker and richer in color than when mixed with Hydroment latexes or water.

PRODUCT USES
Hydroment 1900 Epoxy Modified grouting and setting systems are ideally suited for commercial or residential kitchens; countertops and backsplashes; restaurants; bathrooms; malls; concourses; service garages; food processing or packaging plants; or anywhere stain and chemical resistance or superior shear/bond strengths are required.

As A Mortar
When used with Hydroment Sanded Ceramic Tile Grout, 1900 is designed for interior and exterior installations to set all ceramic, quarry, porcelain, granite, slate, cultured marble, pre-cast terrazzo and dimension stone tile. Use over properly prepared concrete; structurally sound, exterior grade plywood (interior/dry use only); cementitious backer board; Ultra-Set^® ; and existing, well bonded vinyl/VCT or ceramic tile. NOTE: Not for use with moisture sensitive stone.

As A Grout
When used with Hydroment Sanded Ceramic Tile Grout, 1900 is designed for interior or exterior installations to grout all ceramic, quarry, porcelain, granite, slate, cultured marble, structurally glazed tile, pre-cast terrazzo and dimension stone tiles where joint width is 1/8” to 1 1/2 ”.

DIRECTIONS FOR USE: Read and understand data sheet completely before installation. Follow applicable ANSI and TCA installation standards.

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.

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.

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.

Application Over Plywood: Maximum joist spacing shall be 16” on center. Plywood shall be Underlayment Exterior Grade or C-C Plugged Exterior Grade plywood (or better). If the existing floor is less than 1” thick, glue and nail 15/32” or 1/2” APA Underlayment Exterior Grade or C-C Plugged Exterior Grade plywood to the floor. Glue and nail using 5D or 6D (1 1/2 ” or 2”) cement coated screw shank nails 6” on center along the panel edges and a maximum of 8” on center each way throughout the panel. Allow 1/8” gap between underlayment sheet edges and all areas that abut walls, drains, posts, etc., these areas shall be filled with mortar when tiles are installed. Clean and rough sand the plywood. Due to the limitations of plywood as a substrate, Hydroment 1900 Modified Mortar is not intended for use on plywood in exterior, wet interior, or applications subject to heavy/commercial traffic

Application over Existing Vinyl/VCT Flooring: Vinyl must be clean, wax-free and well-bonded to substrate. Do not install over cushion-backed or perimeter bonded sheet vinyl. Remove any loose pieces of vinyl or flooring. Ensure the exposed substrate is suitable for application.

Application over Existing Ceramic Tile:
Tile must be clean and well-bonded to substrate. Mechanical abrasion with a Carborundum disk, followed by a clear water wash is recommended. Installation must be thoroughly rinsed and dry before setting the new tile.

Clean-up: Clean all tools and equipment with soap and water. Do not allow material to dry on surface of tile.
Curing: Keep all foot traffic off the installation until tile is firmly set (approximately 12 hours). Set times are dependent upon temperature and humidity.
Grouting: Depending on ambient, slab, and material temperatures, grouting can generally begin after 12 hours with any quality Hydroment grouting system. Allow 48 hours before grouting with any 100% solids epoxy grout.

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.

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 re-temper by adding more liquid.

Application: 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 degree 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 degree angle working diagonally across the face of the tile.

Initial Cleaning: Depending on humidity and temperature, begin initial cleaning after grout becomes firm, usually 45 to 60 minutes. Using a slightly dampened sponge, clean tile by working in a diagonal motion to the grout joints. Rinse sponge frequently using two pails of water, one for rinsing out the heavy residue and the other for rinsing the sponge with clean water. Avoid cleaning with excessive water as it will cause shade variations or efflorescence.

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. Use Hydroment^® Remove^™ or Ceramaseal® Hydroclean^™ for cleaning difficult grout haze. Never use acid cleaners as they may result in irreversible damage to the grout or tile.

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

Curing: Keep all foot traffic off the installation until grout is firmly set (approximately 24 hours).

LIMITATIONS
