INSTALLATION Surface Preparation All surfaces should be between 40°F (4°C) and 90°F (32°C) and structurally sound, clean and free of all dirt, oil, grease, paint, concrete sealers or curing compounds. Rough or uneven concrete surfaces should be made smooth with LATICRETE Latex Portland Cement Underlayment to provide a wood float (or better) finish. Dry, dusty concrete slabs or masonry should be dampened and excess water swept off. Installation may be made on a damp surface. Note: Latex portland cement mortars do not require a minimum cure time for cement slabs. All slabs must be plumb and true to within 1/4" (6 mm) in 10 ft (3 m). Expansion joints shall be provided through the tile work from all construction or expansion joints in the substrate. Follow ANSI specification A108.01-3.7 "Requirements for Movement Joints: Preparations by Other Trades" or TCNA detail EJ-171 "Movement Joints—Vertical & Horizontal". Do not cover expansion joints with mortar. Mixing Stir LATICRETE 3701 Mortar Admix thoroughly before use. Application Mortar Bed Mixing Mortar Bed—Dry Pack Consistency for floors Mix a 60 lb bag (27 kg) of LATICRETE 226 Thick Bed Mortar to 0.7 gal (2.7 l) of LATICRETE 3701 Mortar Admix. Five (5) gallons (19 l) of LATICRETE 3701 Mortar Admix mixes with approximately 7 bags of LATICRETE 226 Thick Bed Mortar, yielding approximately 45 ft2 (4 m2 ) @ 1" (25 mm) thick. Mix to a stiff, semi-dry consistency (refer to bag for mixing hints). Mix ratio may vary dependent upon weight of finish. Bonded Mortar Bed—Installation Before placing mortar, apply a slurry bond coat made from LATICRETE 254 Platinum or LATICRETE 4237 Latex Additive mixed with LATICRETE 211 Powder. While the slurry bond coat is wet, spread the mortar and compact well. If placing tile immediately, apply a slurry bond coat, made from either LATICRETE 254 Platinum or LATICRETE 4237 Latex Additive mixed with LATICRETE 211 Powder to the mortar. While the slurry bond coat is wet and sticky, place the tile and beat in well. Refer to TDS 143 "Slurry Bond Coats – When & Where to Use" for more information on slurry bond coats. Unbonded Mortar Bed—Installation Before placing mortar , place a cleavage membrane (e.g. 4 mil thick polyethylene sheeting or 15 lbs, builder felt) on the substrate. Place mortar over the cleavage membrane (approximately 1/2 the depth of the mortar bed). Next, place 2" × 2" (50 mm × 50 mm), 16 gauge galvanized welded wire mesh over the mortar. Then, place the balance of the mortar bed. The wire mesh should be suspended in the middle of the mortar bed. Spread the mortar and compact well. Minimum mortar bed thickness shall be 2" (50 mm). If placing tile immediately, apply a slurry bond coat, made from either LATICRETE 254 Platinum or LATICRETE 4237 Latex Additive mixed with LATICRETE 211 Powder to the mortar. While the slurry bond coat is wet and sticky, place the tile and beat in well. Note: A slurry bond coat should also be applied to the edges of mortar beds installed from previous work periods. Application Wall Renders Mixing Wall Renders Mix a 60 lb bag (27 kg) of LATICRETE 226 Thick Bed Mortar to 1 gal (3.8 l) of LATICRETE 3701 Mortar Admix. Five (5) gallons (19 l) of LATICRETE 3701 Mortar Admix mixes with approximately 5 bags of LATICRETE 226 Thick Bed Mortar, yielding approximately 64 ft2 (5.8 m2 ) @ 1/2" (12 mm) thick. Mix to a plastic consistency. Wall Renders—Installation No slurry bond coat is required prior to placing wall renders. Apply wall render with a steel trowel pressing mortar into good contact with the substrate. Apply "scratch coat" first – not to exceed 1/2" (12 mm) thickness. Scratch mortar before it hardens. After "scratch coat" hardens, apply the "brown or float coat" working the mortar into good contact with the scratch coat. Do not exceed 5/8" (15 mm) thickness per lift. Scratch all lifts that will receive additional float coats. Float wall with steel trowel and straight edges to form a plumb and true mortar surface. Allow the completed render coats to cure for 24 hours at 70°F (21° C) prior to the installation of tile. Application Concrete Repair and Resurfacing—Leveling Mortar Consistency Mixing Leveling Mortars Mix a 60 lb bag (27 kg) of LATICRETE 226 Thick Bed Mortar to 1 gal (3.8 l) of LATICRETE 3701 Mortar Admix. Five (5) gallons (19 l) of LATICRETE 3701 Mortar Admix mixes with approximately 5 bags of LATICRETE 226 Thick Bed Mortar, yielding approximately 64 ft2 (5.8 m2 ) @ 1/2" (12 mm) thick. Mix to a plastic consistency. Mix ratio may vary dependent upon weight of finish. Concrete Repair and Resurfacing—Installation Before placing mortar, apply a slurry bond coat made from LATICRETE 254 Platinum or LATICRETE 4237 Latex Additive mixed with LATICRETE 211 Powder. Apply a slurry bond coat to all reinforcing steel and existing clean, sound and stable concrete surfaces just prior to placing the mortar. While the slurry bond coat is wet and sticky place the topping mortar. Compact the surface of the mortar with a flat trowel and ensure all voids are filled. Avoid over troweling. Application Thin-Set Mortar Mixing As a Thin-Set Additive Use approximately 1.5–1.75 gallons (5.7–6.6 l) of LATICRETE® 3701 Mortar Admix to a 50 lbs (22.7 kg) of LATICRETE Thin-Set Mortar. Place LATICRETE 3701 Mortar Admix in a clean plastic pail. Do not dilute. Add LATICRETE Thin-Set Mortar to LATICRETE 3701 Mortar Admix and mix to a smooth, trowelable consistency. Allow mortar to slake for 5–10 minutes. Adjust consistency if necessary. Remix and apply with the proper sized notched trowel. Installation Apply mortar to the substrate with the flat side of the trowel, pressing firmly to work into surface. Comb on additional mortar with the notched side. Note: Use the proper sized notched trowel to ensure full bedding of the tile. Spread as much mortar as can be covered with tile in 15–20 minutes. Back butter large tiles >8" × 8" (>200 × 200 mm) to provide full bedding and firm support. Place tiles into wet, sticky mortar and beat in using a beating block and rubber mallet to embed tile and adjust level. Check mortar for complete coverage by periodically removing a tile and inspecting bedding mortar transfer onto back of tile. If mortar is skinned over (not sticky), remove and replace with fresh mortar. Application Grout Mixing As a Grout Additive Use approximately 1/2 gallon (1.9 l) of LATICRETE 3701 Mortar Admix to 25 lbs (11.3 kg) of LATICRETE 1500 Sanded Grout. Add LATICRETE 1500 Sanded Grout to LATICRETE 3701 Mortar Admix and mix to a smooth, stiff consistency. Use LATICRETE 3701 Mortar Admix full strength for exterior applications; dilute 1/1 with clean water for interior use. Installation Before starting to grout remove spacers and debris in grout joints and remove dust and dirt using a wet sponge. Do not leave water standing in joints. Apply grout release or sealer if necessary. Refer to TDS 400 "LATICRETE Grout Guide" for more information on grouting. Grout installation after a minimum of 24 hours curing time at 70°F (21°C). Dampen tile surface with water. Spread with a sharp, firm rubber grout float. Work the grout paste into the joints until completely filled. Use diagonal strokes to pack the joints. Ensure that joint is filled and the grout is not just sitting on top (i.e. "bridging the joint"). Cold Weather Note: The setting of portland cement mortars and grouts are retarded by low temperatures. Protect finished work for an extended period when installing in cold weather. For faster setting mortar use LATICRETE Thin-Sets with LATICRETE 101 Rapid Latex Admix. Do not set tile when surface temperature is below freezing or when substrate is frozen. Hot Weather Note: The evaporation of moisture in portland cement mortars is accelerated by hot, dry conditions. Apply to dampened surfaces and protect freshly spread mortar and finished work when installing in temperatures over 90°F (32°C). Cleaning Mortar Clean tools and tile work with water while mortar is fresh. Grout Primary Cleaning Remove excess grout from the face of the tiles with the edge of the grout float. Hold the float at a 90° angle and pull it diagonally across the joints and tile to avoid pulling out the material. Grout Secondary Cleaning Remove remaining grout with a damp sponge (not wet) or a damp towel. Work diagonally to the joints. Allow to dry. When the grout joints are firm polish the surface with a coarse nylon pad or coarse cloth and minimal water. Note: Use caution when polishing soft glazed tiles or polished stone.
