SGM EGS Mortar Grout System is a 100 percent solid epoxy grout and mortar that is highly chemical resistant, stain-resistant, and yields exceptionally high strength. This system is ideal for use in foodservice locations, laboratories, and other environments that must remain sterile and sanitary at all times. SGM EGS Mortar Grout System is a water-cleanable, three-component system that is designed for setting and grouting ceramic tile and pavers over a wide variety of substrates. Meets ANSI A118.3.

Product Details


When used as a mortar, the substrate must be dry, clean, sound and dimensionally stable. It must be free of loose particles, wax, sealers, curing compounds, and grease. Concrete and cement subfloors must cure for twenty-eight (28) days and be free of moisture.

Recommended Substrates

  • Fully cured dry concrete slabs (twenty-eight days)
  • Portland cement mortar beds
  • Tile over tile
  • Properly prepared VCT or sheet vinyl
  • Exterior grade plywood
  • Cementious backerboard
  • Fiber-based backerboard
  • Other substrates — contact SGM technical department


To bond ceramic tile, marble, et cetera over vinyl asphalt and resilient flooring, floors must be bonded well to its subfloor and free of any wax, oil, dust, or paint particles. Install expansion joints according to local building codes.


Apply the mortar liberally with the flat side of a trowel. Use sufficient pressure to work mortar in for good contact. Fill in gaps left between boards at this time. Then comb with a properly notched trowel to leave uniform ridges. Place tiles while the surface is wet and tacky. Spread only as much mortar as can be covered in twenty (20) minutes or while the surface is wet and tacky. Place tile with twisting motion and beat lightly to achieve a minimum of 100 percent surface contact with each tile.

  • NOTE: Do not apply below 60°F (sixty degrees Fahrenheit).


SGM EGS Mortar Grout System may be used to grout after tiles are firmly set (approximately one to two days). The tile surface must be clean and dry. Porous tiles may require the use of grout release to prevent staining (consult tile manufacturer). Using a hard rubber epoxy float, force grout into joints, leaving it flush with the tile surface. Remove any excess grout from the surface of the tile before the material begins to set. Clean the remaining residue with clean water and a nylon pad. Do not use excessive water during clean up. Warm water will assist in cleanup. Follow ANSI 108.6 specifications.


For optimum results, protect from foot and light traffic for at least 24 hours, normal traffic for 72 hours, and heavy traffic for seven (7) days. Normal, routine cleaning can be accomplished after seven (7) days.


Rubber gloves and protective clothing are recommended. Sensitive skin may have an allergic reaction to epoxy system. Product is an eye irritant. Wash hands thoroughly after handling and before smoking or eating. KEEP OUT OF REACH OF CHILDREN.


Using a clean container, add entire contents of both Part A and Part B simultaneously, then add Part C powder. Mix until a completely consistent, homogeneous color is obtained.

  • NOTE: A slow speed mixer is recommended (approximately 150 RPM), or manually mix with margin trowel or similar. Avoid high speed mixing or prolonged mixing which will shorten pot life and entrain air.


Clean hands, tools, and containers with warm, soapy water. To clean tiles, wait until the grout joint has begun to set then use a nylon buffing pad, rubbing in a circular motion. SGM EGS Mortar Grout System is extremely difficult to remove after setting. Do not allow excess material to dry on the surface of tiles or tools.


Greater than 60 (sixty) minutes.
