Applicable Standards

Detailed installation procedures and use of epoxy mortars may be found in the TCNA Handbook under F-113, F-114, F-115, F-116, F-125, F-128, F-143, F-131, F-132, F-134, F-135, F-200, F-205, TR-711 and TR-712 and in addition, in ANSI A108.6. Exceeds ANSI A118.3 specifications. Conforms to requirements for chemical-resistant, water cleanable tile setting and grouting epoxy found in ANSI A108.6 and ANSI A118.3.

Conformance to Building Codes

Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.

Composition of Product

2-part formula, with Part A liquid epoxy resin and Part B liquid epoxy hardener combined with Portland cement and aggregates. Different liquids are required based on desired color.

Environmental Consideration

Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product can contribute towards LEED® v3 certification:

  • Up to 2 points towards MR Credit 5, Regional Materials
  • Up to 1 point towards IEQ Credit 4.1, Low-Emitting Materials – Adhesives & Sealants

Suitable Substrates

  • Countertops, backsplashes, tub and shower areas, sunken tile tubs and swimming pools that are continually wet
  • Plumb and true masonry, concrete, cured Portland cement mortar beds
  • Bonds directly to brick, ceramic tile, cementitious back units, steel, glass and fiberglass

General Surface Prep

USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.

All surfaces on which tiles are to be set must be dry, structurally sound, and not subject to temperatures below 65° F (18° C) or above 95° F (35° C). Surfaces must be dry and free of all grease, oil, dirt, dust, curing compounds, sealers, coating, efflorescence, old adhesive residues, gypsum-based underlayments and any other foreign matter.

Health Precautions

May irritate eyes. May irritate skin. Do not swallow. Do not get in eyes. Do not get on skin or clothing. Do not breathe fumes. KEEP OUT OF REACH OF CHILDREN. Wear safety glasses and chemical-resistant gloves. First Aid Treatment: If swallowed, call a poison control center or doctor immediately. Do not induce vomiting. If in eyes, rinse with water 15 minutes. If on skin, rinse well with water.

Limitations to the Product

  • Should not be used in an environment with temperature requirements above 250°F (121°C) for any extended period of time.
  • When used to install tile in an area that will be continually wet (e.g. swimming pools, gang showers, etc.), it is recommended that the complete installation be cured 14 days prior to full submersion with chemically treated water.
  • Epoxy, epoxy residue, or wash water will discolor painted or anodized surfaces upon contact. Protect these surfaces from exposure.
  • Vertical grout joint width should not exceed 1/2" (13 mm).
  • Should be tested for possible staining or slight color changes when used with porous, absorptive, textured tile and stone units such as rough textured ceramic tile, natural stone or marble.
  • All epoxies are temperature sensitive. Epoxies are easiest to apply when temperatures are between 70°F and 85°F (21°C and 29°C). Lower temperatures will cause the epoxy to become stiff and more difficult to work and will extend initial set. Higher temperatures will cause the epoxy to become more fluid and will accelerate the set.
  • With all epoxies, a crystallization effect can occur when the liquid gets below 45°F (7°C) and/or has experienced multiple cycles of high and low temperature changes. If material is hard, place the sealed container (with the lid on), in warm tap water at approximately 120°F (49°C) for 10 to 20 minutes, and when re-liquified, let the material return to room temperature before mixing.
  • Not recommended in some manufacturing facilities where heavy solvents are used. Consult Technical Services on questionable installations.
  • Colors may be slightly different than shown on color samples. When color considerations are critical, a mock-up should be constructed prior to final selection and application.
  • The use of non-rinse, enzyme-based cleaners is not recommended because they will break down the organic materials in epoxy grout, causing permanent damage.
  • Note: some glass tile manufacturers do not recommend using epoxy grout during installation. If using glass tile, confirm with the tile manufacturer before proceeding.
  • Not for use in movement joints or changes of plane in the tile installation. In these areas us an appropriate caulk or sealant such as Commercial 100% Silicone Caulk or Polyblend® Ceramic Tile Caulk.

Mixing Procedures

Stir contents of Part "A" thoroughly, then combine entire contents of part "A" and "B" in a clean mixing container. Stir with a margin trowel until thoroughly mixed. Gradually add a 25 lb (11.34 kg) bag of Polyblend® Sanded Grout into premixed liquids. Using a low speed mechanical mixer (300 RPM or less), mix until smooth. Consistency can be adjusted by reducing the amount of powder added up to 25% (17 lbs). Typically narrow joints require less Polyblend®. For vertical installations, add Non-Slump Epoxy Additive according to directions.

Application of Product

Remove all mixed epoxy from container and place in small piles where work is to proceed. This will extend working time. When grouting walls, place epoxy on mortar board placed on the floor. Using an epoxy grout float, pack joint full with epoxy being careful not to leave voids during application. Remove excess epoxy by holding grout float at a 90° angle and pulling the float diagonally across the grout joints. Removing as much epoxy as possible will make final cleaning easier. Avoid gouging joints. Allow joint to set for approximately 15-30 minutes or until they begin to firm. Time will vary depending upon substrate and ambient temperature. Do not allow epoxy to set on face of tile. Apply liberal amounts of clean, cool water to the grouted area. Adding a few drops (maximum) of dishwashing liquid to the water will aid in cleanup. Using a white nylon pad, work in a circular motion to loosen epoxy film and finish joints smoothly. If necessary add more water to aid cleaning. Clean film from tile with a damp cotton towel and clean water. Change rinse water frequently to aid cleanup and minimize epoxy residue left behind. If a film is noticed after final cleanup, allow joints to cure for 2 hours (depending upon temperature) and rinse grouted tile with clean water and hydro sponge.

Curing of Product

Generally, light foot traffic can be allowed in 18 hours at 75°F (24°C), normal foot traffic in 24 hours and heavy foot traffic in 72 hours. Epoxy should be kept dry and protected from exposure to food or other chemicals, that could stain or attack the grout, for 7 days after installation.

Exterior applications must be protected from rain, snow and other wet conditions for at least 7 days with temperature above 50° F (10° C). If inclement weather is expected, protect the work area with tenting at least 1 foot (30 cm) above the finished surface to allow air flow. Enclose and protect exterior installations and maintain >50° F (10° C) temperatures for at least 72 hours for proper cure.

Sealing of Grout

Sealing is not necessary

Cleaning of equipment

Clean tools and hands with water before material dries.


Keep from freezing.

Product Maintenance

For routine cleaning, use TileLab® Grout & Tile Cleaner or TileLab® Heavy-Duty Cleaner & Stripper.
