INSTALLATION

Surface Preparation
Installation Over Concrete Slabs
  • ALL CONCRETE SURFACES MUST BE SHOT BLASTED/MECHANICALLY ABRADED
  • All surfaces must be primed with LATICRETE® Admix and Primer and should be between 50°F (10°C) and 90°F (32°C). Surfaces should be structurally sound, clean and free from all dirt, oil, grease, adhesives, paint, sealers or curing compounds
  • New concrete surfaces must be at least 28 days old
  • 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
Installation Over Wooden Sub-Floors
  • Installer must verify that deflection under all live, dead and impact loads of interior plywood floors does not exceed industry standards of L/360 for ceramic tile and brick or L/480 for stone installations where L=span length
  • Minimum construction for interior plywood floors:
    SUBFLOOR: 5/8" (15 mm) thick exterior glue plywood, either plain with all sheet edges blocked or tongue and groove, over bridged joists spaced 16" (400 mm) o.c. maximum; fasten plywood 6" (150 mm) o.c. along sheet ends and 8" (200 mm) o.c. along intermediate supports with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 1/8" (3 mm) between sheets and 1/4" (6 mm) between sheets edges; all sheet ends must be supported by a framing member; glue sheets to joists with construction adhesive.

    UNDERLAYMENT: 5/8" (15 mm) thick exterior glue plywood fastened 6" (150 mm) o.c. along sheet ends and 8" (200 mm) o.c. in the panel field (both directions) with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 1/8" (3 mm) to 1/4" (6 mm) between sheets and 1/4" (6 mm) between sheet edges and any abutting surfaces; offset underlayment joints from joints in subfloor and stagger joints between sheet ends; glue underlayment to subfloor with construction adhesive. Refer to Technical Data Sheet 152 "Bonding Ceramic Tile, Stone or Brick Over Wood Floors" for complete details.
  • Prime cleaned and properly prepared surface with LATICRETE Admix and Primer as described in "Priming" section
  • Allow primer to dry accordingly. Install 3.2# galvanized diamond metal lath over entire wood floor. Ensure proper fastening to eliminate any loose sections. Do not install over wet primer
    Note: Galvanized diamond metal lath can be omitted when installing LATICRETE 84 LatiLevel over LATICRETE Floor HEAT
  • Install LATICRETE 84 LatiLevel over floor in accordance with "Application" section below
Installation Over Cutback Adhesive
  • Consult adhesive manufacturer and any governmental agencies for proper removal of any adhesive containing asbestos. Consult the Resilient Floor Covering Institute "Recommended work & practices for removal of resilient floor covering" for removal instructions. All cutback adhesive must be removed by thoroughly shot-blasting the floor prior to installation of LATICRETE 84 LatiLevel
Installation Over Existing Ceramic Tile, Stone or Cement Terrazzo
  • Skim coat existing ceramic tile, cement terrazzo or stone with LATICRETE 254 Platinum Rapid (min. 1/8" [3 mm] thick continuous coating). Allow to dry
  • Prime surface according to "Priming" section and install LATICRETE 84 LatiLevel according to "Application" section
Priming

Use LATICRETE Admix & Primer with every application. Shake thoroughly before using. Pour, mop, or spray primer onto the surface. Apply an even thickness of primer to the prepared substrate using a bristle broom to ensure the primer is absorbed into the substrate, removing any puddles or thick areas. Per 5 qt. (4.8 l) jug of primer, dilute 1:1 with clean potable water in a clean mixing pail. Coverage is approximately 500 ft2 (45 m2 ) when mixed 1:1. If primer dries within 45 minutes, slab is excessively dry and will require another application as directed above. Allow the primer to dry to a clear film usually 1–3 hours, but less than 24 hours before application of LATICRETE 84 LatiLevel . Note: Keep primed surface clean. Do not allow any foot traffic onto surface.

Mixing

Place 4.5–4.75 qts (4.25–4.5 l) of clean potable water into a clean pail. Add one 50 lb (22.7 kg) bag of LATICRETE 84 LatiLevel slowly into the pail; mix as the material is poured. Use a high speed mixer (500 rpm) and mix thoroughly for one minute for a smooth creamy mix with no clumps. Follow all mixing instructions on bag. Be sure to not add too much water. Mix no more than two bags at a time with appropriate water.

Application

Perimeter Isolation Strip
It is essential that all walls and building elements are isolated from the self-leveling underlayment pours to ensure proper expansion allowance against all restraining surfaces.

Note: It is recommended to install a perimeter isolation strip before the installation of LATICRETE® 84 LatiLevel . Attach the perimeter isolation strip to the perimeter wall of the entire subfloor, as well as around the perimeter of any protrusions, in order to isolate the floor and the wall/restraining surfaces. Temporarily fasten perimeter isolation strip in place with staples masking, duct, or carpet tape. The perimeter isolation strip can then be removed after the tiles have set firm. The joints can then be filled with LATICRETE Latasil.
All concrete surfaces are to be shot blasted/mechanically abraded to ensure any contaminants, such as sealers or glue, are removed. Pour or pump the LATICRETE 84 LatiLevel over the primed substrate and spread with a spike roller or gauging rake. Use a smoothing paddle to combine pours and to obtain a flat smooth surface. Floor will be ready for foot traffic in 16 hours. When LATICRETE 84 LatiLevel has hardened, ceramic tile may then be installed using a LATICRETE Latex Thin-Set Mortar. Follow manufacturer's recommendations for installing vinyl tile, linoleum, carpet, wood parquet or seamless epoxy flooring over concrete. Before installing wood or resilient flooring, consult manufacturer for recommendations on substrate moisture content requirements. Allow LATICRETE 84 LatiLevel to dry in accordance with those recommendations. For applications requiring pours between 1" and 1 1/2" (25–38 mm), use LATICRETE 86 LatiLevel.

Cleaning
Clean tools with water while mortar is fresh.
