Environmental Consideration

Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices.

Suitable Tile Types

  • Brick and stone veneer
  • Cement-based precast terrazzo
  • Natural stone tile

Suitable Substrates

  • Concrete, mortar beds, masonry, Portland cement plaster
  • WonderBoard® Lite cement backerboards
  • Liquid applied waterproofing membranes such as RedGard® and Custom® 9240
  • Crack prevention sheet membranes such as Crack Buster® Pro
  • Exterior Grade Plywood (interior residential and light commercial dry areas)
  • Gypsum wallboard (interior dry areas)
  • Existing ceramic tile
  • Fully-bonded sheet vinyl flooring
  • Plastic laminates
  • Cutback adhesive (see preparation instructions)

General Surface Prep

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

Surfaces must be structurally sound, clean, dry and free from grease, oil, dirt, curing compounds, sealers, adhesives or any other contaminant that would prevent a good bond. Glossy or painted surfaces must be sanded, stripped and cleaned of waxes, dirt or any contaminants. Concrete must be cured 28 days and accept water penetration. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a broomed or brushed finish to enhance the bond. Plywood flooring including those under resilient flooring must be structurally sound and meet all ANSI and deflection requirements. For questions about proper subfloor installation, call Technical Services. Smooth concrete surfaces, existing glazed tile, terrazzo, or polished stone should be roughened or scarified. Sheet vinyl must be-well bonded and stripped of old finish. Roughen the surface by sanding or scarifying, rinse and allow to dry. Expansion joints should never be bridged with setting material. Do not sand flooring materials containing asbestos. Ambient temperature, surfaces and materials should be maintained at a temperature above 50° F (10° C) or below 100° F (38° C) for 72 hours.

Health Precautions

WARNING: Wear rubber gloves and eye protection. Avoid eye contact or prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, flush with water for 15 minutes. Consult physician immediately. Avoid breathing dust. This product contains amorphous silica. Use only with exhaust ventilation or approved respirator. KEEP OUT OF REACH OF CHILDREN. DO NOT TAKE INTERNALLY.

Limitations to the Product

Bonding to Concrete Surfaces

Concrete or plaster must be fully cured and must accept water penetration. Test by sprinkling water on various areas of the substrate. If water penetrates, then a good bond can be achieved; if water beads, surface contaminants are present, and loss of adhesion may occur. Contaminants should be mechanically removed before installation. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a broomed or brushed finish to enhance the bond. Smooth concrete slabs must be mechanically abraded to ensure a good bond.

Bonding to Plywood Surfaces

Plywood floors, including those under resilient flooring, must be structurally sound and must meet all ANSI A108.01 Part 3.4 requirements. See TCNA F150. For questions about proper subfloor installation, call Custom® Building Products.

Bonding to Backerboards

WonderBoard® Lite Backerboard may be installed over plywood subfloors as an alternative to an additional layer of plywood,. Refer to TCNA F144.

Bonding to Existing Surfacing Material

Plywood flooring must be structurally sound and meet all ANSI and deflection requirements. Resilient flooring or plastic laminates must be well-bonded, clean and free of all contaminates. Roughen the surface by sanding or scarifying, rinse and allow to dry. Do not sand flooring containing asbestos. For existing well-bonded ceramic tile, mechanically abrade with carborundum stone. Rinse and allow to dry. When sanding we recommend the use of an approved respirator.

Bonding to Cutback Adhesive

Adhesive layers must be removed as they reduce mortar bond strength to cement surfaces. Use extreme caution as adhesives may contain asbestos fibers. Do not sand or grind adhesive residue, as harmful dust may result. Never use adhesive removers or solvents, as they soften the adhesive and may cause it to penetrate into the concrete. Adhesive residue must be wet-scraped to the finished surface of the concrete, leaving only the transparent staining from the glue. Do a test bond area first, to determine desirable results. Refer to the RFCI Pamphlet, "Recommended Work Practices for Removal of Resilient Floor Coverings", for further information.

Mixing Ratios

Mix 1:1 with 100% Solids Epoxy Grout. After mixing the resin (Part A) and hardener (Part B) together for 100% Solids Epoxy Grout, add Non-Slump Epoxy Additive and mix well. Then add the grout powder according to package directions.

Application of Product

Installation to conform to ANSI A108.6.

Cleaning of equipment

Epoxy must be cleaned from tools with water quickly after application. Do not allow epoxy to cure on surface of tile. Do not attempt to work more than one unit at a time. Larger units may require a two or three man crew to spread or clean.

Storage

Keep from freezing. Close container after each use.

Product Maintenance

Properly installed product requires no special maintenance.

Expected Wear

Properly installed tile will last for more than 60 years.
