Formulated to be used with Thick Bed Mortar or as an additive to a site-mixed sand and cement blends to form a high strength thin-bed mortar. Adds flexibility and shock resistance for use in heavy traffic conditions in industrial, commercial and institutional installations. Frost-resistant, it's excellent for exterior use in cold climates. Also for use in wet areas and underwater installations such as pools and fountains. Use as an additive with Thick Bed Mortar or to a site-mixed sand and cement blend.

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.
Do not take internally. Avoid eye and skin contact. If eye contact occurs, immediately flush with water for 15 minutes and consult a physician.
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.
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.
WonderBoard® Lite Backerboard may be installed over plywood subfloors as an alternative to an additional layer of plywood,. Refer to TCNA F144.
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.
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.
Thoroughly mix a 50 lb (22.68 kg) bag of mortar with 5 quarts (4.73 L) CustomCrete® Latex Mortar Admix to a smooth, paste-like consistency. For a sand/cement site mix, dry blend one 94 lb (42.68 kg) bag of Portland cement with one 100 lb (45.36 kg) bag of #60 silica sand and mix with 5 gallons (18.93 L) of CustomCrete®.
Mix by hand or use a low speed (150-200 RPM) 1/2" (13 mm) drill. Let slake or stand 5-10 minutes, stir again and use. Stir occasionally to keep fluffy, but do not re-temper (add more additive). When properly mixed, troweled ridges will stand with little or no slump.
Refer to the Thick Bed Mortar directions for proper surface preparation and application instructions.
Allow to cure for a minimum of 24 hours before grouting or light traffic, depending upon temperature and humidity. In areas that will be continually wet (e.g. swimming pools, fountains), it's recommended that the completed installation be cured a minimum of 14 days and allowed to thoroughly dry before water submersion. Curing times vary with weather conditions and humidity; special conditions may require curing up to 28 days.
Clean with soap and water before material dries. Cured material is difficult to clean from surfaces.
Keep from freezing. Close container after each use.
Properly installed product requires no special maintenance.
Properly installed tile will last for more than 60 years.
