Use of this product can contribute towards LEED® v3certification:Up to 2 points towards MR Credit 5, Regional MaterialsUp to 2 points towards MR Credit 4, Recycled ContentUp to 1 point towards IEQ Credit 4.1, Low­Emitting Materials –Adhesives & Sealants5 InstructionsGeneral Surface PrepSurfaces must be structurally sound. Remove all grease, oil, dirt,curing compounds, sealers, adhesives or any other contaminant thatwould prevent a good bond. Glossy or painted surfaces must besanded, or abraded, and stripped of all contaminants. Concrete mustbe cured 28 days and accept water penetration. Concrete must be freeof efflorescence and not subject to hydrostatic pressure. Concreteslabs should have a coarse finish to enhance the bond. Plywoodflooring including those under resilient flooring must be structurallysound and meet all ANSI and deflection requirements. For questionsabout proper subfloor installation, call Technical Services. Smoothconcrete surfaces, existing glazed tile, terrazzo, or polished stoneshould be scarified. Sheet vinyl must be well bonded and stripped ofold finish. Roughen the surface by sanding or abrading, then rinse andallow to dry. Expansion joints should never be bridged with settingmaterial. Do not sand flooring materials containing asbestos. Ambienttemperature should be maintained above 50° F (10° C) or below 100°F (38° C) for 72 hours to achieve proper bond.Bonding to Concrete SurfacesConcrete or plaster must be fully cured and must accept waterpenetration. Test by sprinkling water on various areas of the substrate.If water penetrates, then a good bond can be achieved; if waterbeads, surface contaminants are present, and loss of adhesion mayoccur. Contaminants should be mechanically removed beforeinstallation. Concrete must be free of efflorescence and not subject tohydrostatic pressure. Concrete slabs should have a coarse finish toenhance the bond. Smooth concrete slabs must be mechanicallyabraded to achieve proper bond.Bonding to Lightweight Cement and Gypsum SurfacesLightweight or gypsum based underlayments must obtain a minimum2000 psi (13.8 MP) compressive strength. The underlayment must besufficiently dry and properly cured to the manufacturer’s specificationsfor permanent, non-moisture permeable coverings. Surfaces to betiled must be structurally sound and subject to deflection not to exceedthe current ANSI Standards. Surfaces shall be free of all grease, oil,dirt, dust, curing compounds, waxes, sealers, efflorescence, or anyother foreign matter.All Lightweight cement or Gypsum surfaces should be primed with aproperly applied sealer or a primer coat of RedGard, consisting of 1part RedGard diluted with 4 parts clean, cool water. Mix in a cleanbucket at low speed to obtain a lump free solution. The primer can bebrushed, rolled or sprayed to achieve an even coat. Apply the primercoat to the floor at a rate of 300 sq. ft.l (7.5 sq. m/L). Drying timedepends on site conditions, but is normally less than 1 hour. Extremelyporous surfaces may require 2 coats. At this point, RedGard can beapplied to the primed lightweight or gypsum based surface. Refer tothe individual product data sheet or packaging directions for applicationinstructions. Expansion joints must be installed in accordance withlocal building codes and ANSI/TCNA guidelines. Refer to TCNA EJ171.Bonding to Plywood SurfacesPlywood floors, including those under resilient flooring, must bestructurally sound and must meet all ANSI A108.01 Part 3.4requirements. Maximum allowable deflection: L/360 tile L/720 stone.See TCNA F150-13 Tile Installations, TCNA F141-13 and F250-13 forStone. For questions about proper subfloor installation requirements,call Custom technical services.Bonding to BackerboardsAs an alternative to an additional layer of plywood, WonderBoardbackerboard may be installed over plywood subfloors for ceramic tileinstallations. Refer to TCNA F144-13 tile installations, TCNA F250-13stone installations. Call Custom technical services when installingnatural stone over plywood subfloor.Bonding to Existing Surfacing MaterialExisting Ceramic Tile, Resilient Flooring or Plastic Laminates: Resilientflooring or plastic laminates must be well bonded, as well as clean andfree of all contaminates. Roughen the surface by sanding or scarifying;rinse and allow to dry. Do not sand flooring that contains asbestos. Forexisting well bonded ceramic tile, mechanically abrade the surface.Rinse and allow to dry. When sanding, an approved respirator shouldbe used.Published Date: 1/31/2014

TILING 09 30 00Porcelain Tile Fortified Thin-Set MortarSetting / TDS-117Bonding to Cutback AdhesiveAdhesive layers must be removed, as they reduce mortar bondstrength to cement surfaces. Use extreme caution; adhesives maycontain asbestos fibers. Do not sand or grind adhesive residue, asharmful dust may result. Never use adhesive removers or solvents, asthey soften the adhesive and may cause it to penetrate into theconcrete. Adhesive residue must be wet scraped to the finishedsurface of the concrete, leaving only the transparent staining from theglue. To determine desirable results, do a test bond area beforestarting. Refer to the RFCI Pamphlet, “Recommended Work Practicesfor Removal of Resilient Floor Coverings” for further information.Expansion Joint placementExpansion joints and cold joints, as described in ANSI A108.01, shouldnever be bridged with setting material. They must be brought throughthe tile work and filled with an appropriate elastomeric sealant, suchas Custom's 100% Silicone. Contact Custom's Technical Services forthe proper treatment of control or saw cut joints. Refer to TCNAEJ171, F125 & F125A.Mixing RatiosMix 6 qts (5.67 L) clean water per 50 lb (22.68 kg) bag of mortar.Mixing ProceduresMix by hand or use a low 150 – 200 rpm speed 1/2" (13 mm) drill toachieve a smooth, paste-like consistency. Let the mixture slake orstand 5 – 10 minutes; stir again and use. Stir occasionally, but do notadd more water. When properly mixed, troweled ridges will standwithout slump.Application of ProductInstallation must conform to ANSI A108.5. Use a properly-sized notchtrowel to ensure proper coverage under tiles. Using the flat side of thetrowel, apply a skim coat of mortar to the surface. With the notch sideof the trowel held at a 45° angle, apply additional mortar to thesurface, combing in one direction. Press the tile firmly into place in aperpendicular motion across ridges, moving back and forth. Theperpendicular motion flattens ridges and closes valleys, allowingmaximum coverage. With some tile, back-buttering is advisable. Adjustthe tile promptly and beat it in with a beating block and rubber mallet.Mortar can be applied up to 1/4" (6 mm) thick after beat in. For thickerapplications, use a medium bed mortar; periodically pull up a tile andcheck the back to ensure proper adhesive coverage. If the material hasskinned over (not sticky to the touch), recomb with the notch trowel; iftoo dry, remove and replace the dry material with fresh material.Curing of ProductCuring time is affected by ambient and surface temperatures andhumidity. Use the following as a guideline. Allow 24 hours beforegrouting or light traffic.Cleaning of equipmentClean with water before the material dries.StorageStore in a cool dry area.Health PrecautionsThis product contains Portland cement and free silica. Avoid eyecontact or prolonged contact with skin. Wash thoroughly afterhandling. If eye contact occurs, flush with water for 15 minutes andconsult a physician. Do not breathe dust; wear a NIOSH approvedrespiratorConformance to Building CodesInstallation must comply with the requirements of all applicable local,state and federal code jurisdictions.6 Availability & CostLocation Item Code Size Color PackageUSA PMG50 50 lb (22.68 kg) Gray BagUSA PMW50 50 lb (22.68 kg) White BagCanada CPMG50 50 lb (22.68 kg) Gray Bag7 Product WarrantyCustom® Building Products warrants to the original consumerpurchaser that its product shall be free from defects in material andworkmanship under normal and proper usage for a period of one yearfollowing the date of original purchase.
