Products : Grout : Epoxy Grout : CEG-Lite™ 100% Solids Commercial Epoxy Grout

CEG-Lite™ 100% Solids Commercial Epoxy Grout

CEG-Lite™ 100% Solids Commercial Epoxy Grout provides stain resistance with a fast cure time for a quick return to service. Its lightweight formula makes it easier to spread than typical epoxy grouts and is water-cleanable. CEG-Lite exceeds ANSI A118.3 performance requirements, is suitable for use on vertical joints without an additive, and can also be used as a mortar. Its two-component formula combines a Part A pigmented hardener with a Part B consisting of resins and lightweight aggregates. CEG-Lite is compatible with both CEG-Lite Part A and CEG Part A epoxy grout color pigment and hardener products.

  • Color consistent, stain and chemical resistant
  • Easy to spread and clean-up
  • No sagging in vertical joints
  • Contains recycled LEED contributing materials

Composition & Materials

2-part formula, with Part A pigmented liquid epoxy hardener and Part B liquid epoxy resin combined with aggregates.


  • 2-Part 100% Solids Epoxy
  • No shrinkage
  • Color consistent and stain resistant
  • Easy to spread and water clean-up
  • No additive needed for critical grouting applications
  • Contains recycled materials that may contribute to LEED® credits
  • Exceeds ANSI A118.3 (100% Epoxy) performance requirements


  • 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.
  • 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.
  • 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.
  • Not recommended in some manufacturing facilities where strong solvents are used. Consult Technical Services on questionable installations. CUSTOM recommends the use of CEG-IG™ Commercial Epoxy Grout for these installations.
  • 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.
  • Some ceramic, glass, marble or stone tiles can be scratched or damaged by the silica aggregate filler. Perform a test on a small area prior to use.


Grout mixture requires two separately-sold parts:

  • Part A 1.3 lb (.58 kg) container of pigmented liquid epoxy hardener, available in 27 standard colors
  • Part B 19 lb (8.6 kg) or 9.5 lb (4.3 kg) liquid epoxy resin combined with aggregates
