Products : Setting : Additives : Thin-Set Mortar Admix
A liquid polymer designed to be used in place of water to increase performance of cement mortar beds, non-modified, thin-set mortars and cement-based grouts. It improves working characteristics and performance of cement-based mixes to boost water resistance, shock resistance and freeze-thaw capabilities for tile, stone or masonry installations. Increases performance of non-modified thin-set mortars for setting dense tile and setting over hard-to-bond surfaces. Thin-Set Mortar Admix can be used with non-modified, thin-set mortars such as, CustomBlend® Thin-Set Mortar and Uncoupling Mat Mortar. It can also be used with Saltillo Grout Mix.
When mixed with non-modified thin-set mortars and mortar bed mixes:
Increases performance for:
American National Standards Institute (ANSI) ANSI A108.5; A118.4; A118.11 of the American National Standards for the Installation of Ceramic Tile
Tile Council of North America (TCNA) TCNA Handbook for Ceramic Tile Installation, TCNA Method EJ171

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.
Expansion joints, control joints and cold joints should never be bridged with setting material. They must be brought through the tile work and filled with an appropriate elastomeric sealant.
Contains latex emulsions. Wear rubber gloves and eye protection. Avoid eye and skin contact. If eye contact occurs, immediately flush with water for 15 minutes and consult a physician immediately. If skin contact occurs, wash immediately with soap and water. Dried material becomes extremely difficult to remove. KEEP OUT OF REACH OF CHILDREN.
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.
FOR USE AS AN ADMIX WITH NON-MODIFIED THIN SET MORTAR
Refer to individual product instructions. Mixing details for Thin-Set Mortar Admix will vary dependant upon non-modified mortar used. See the mixing instructions on CustomBlend® or Uncoupling Mat Mortar bag or data sheet for specific directions.
FOR USE WITH PORTLAND CEMENT AND SAND MORTAR MIXES
Thin-Set Mortar Admix may be used as a fortifying additive to site-mixed or bagged Portland cement and sand mixtures common to masonry or floated mortar beds. Mix 1 part Thin-Set Mortar Admix with 1 part clean water and use as a direct replacement for the water requirement in any mortar mix. Thin-Set Mortar Admix can be used full strength for improved performance.
The total amount of liquid added will vary.
FOR USE AS AN UNMODIFIED TILE GROUT ADMIX
When installing tile over wood substrates and when increased tensile and flexural grout qualities are necessary, use Thin-Set Mortar Admix with water. Mix 1 part clean water with 1 part Thin-Set Mortar Admix prior to mixing liquid with Portland cement grout. Remove excess grout from surface of tile as soon as possible after grouting, as latex-fortified grout becomes extremely difficult to remove when dry. Not for use with Custom's® Polyblend® Grout or Prism® SureColor® Grout.
Clean with water before material dries.
Mortar: Clean with water while mortar is fresh.
Grout: Refer to instructions of non-modified grout for installation and cleaning instructions.
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.
