Products : Grout : Epoxy Grout : 100% Solids Epoxy Grout

100% Solids Epoxy Grout

A two-component system consisting of a resin and hardener that is combined with any Polyblend® Sanded Grout to fill joint widths from 1/8" to 3/8" (3-10 mm). It offers maximum resistance to staining. Delivers a grout that is uniform in color and colorfast. Easy to apply and cleans up easily with water.

Key Features

  • Mix with 25 lb Polyblend Sanded Grout
  • Highly stain and chemical resistant
  • Non-slumping, easy clean-up

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

Composition & Materials

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.


  • Combine with Polyblend Sanded Grout
  • High resistance to staining or chemical attacks
  • Fast clean-up provide easy grout installation
  • For joints 1/8” to 3/8” (3mm to 9 mm) wide.


  • 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.
