All surfaces must be between 40º F (4º C) to 95º F (35º C) and structurally sound (deflection not to exceed 1/360 of the span), dry, clean and free from oil, grease, wax, paint, old adhesives, sealers and curing compounds. Any contaminates which inhibit proper bond must be removed. All sub­strates should be plumb and true, for large and heavy tile maximum allowable variation is 1/8 in 10’ from the required plane, with no more than a 1/16 variation in 24”. Patching, leveling or areas requiring a mortar bed should be prepared using appropriate SikaLevel self-leveling, patching, or SikaTile underlayment products. Expansion joints should comply with EJ171 Movement joint guidelines per TCNA and ANSI requirements using an ASTM C920 sealant.

SUBSTRATES:

Concrete Substrates: All concrete substrates should be cured a mini­mum of 28 days and 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. Smooth steel troweled floors should be roughed up using mechanical chipping, scraping, or shot blasting. Porous dry concrete, and porous backer board must be “SSD” (Surface Saturated with water but, dry to the touch) prior to the application of SikaTile®-500 LHT Lite.

Lightweight Cement and Gypsum Surfaces: Lightweight or gypsum-based underlayment’s must obtain a minimum 2000 psi (13.8 MPa) compressive strength. The underlayment must be sufficiently dry and properly cured to the manufacturer’s specifications for permanent, non-moisture permeable coverings. Surfaces to be tiled must be structurally sound and subject to deflection not to exceed current industry standards. All lightweight cement or gypsum surfaces should be primed with a properly applied sealer or a primer coat of SikaTile®-100 Moisture Guard, consisting of 1 part 100 Moisture Guard diluted with 4 parts clean, cool water. Mix in a clean bucket at low speed to obtain a lump free solution. The primer can be brushed, rolled, or sprayed to achieve an even coat. Apply the primer coat to the floor at a rate of 300 ft2/gal (7.5 M2/L). Drying time depends on site conditions but is normally less than 1 hour. Extremely porous surfaces may require 2 coats. At this point, 100 Moisture Guard can be applied to the primed lightweight or gypsum based surface. Refer to the individual product data sheet or packaging directions for application instructions.

Plywood Substrates: Plywood floors, including those under resilient flooring, must be structurally sound and must meet all ANSI A108.01 Part 3.4 requirements. Maximum allowable deflection: L/360 tile L/720 stone. See TCNA F150-21 tile installations, TCNA F141-21 and F250-21 for stone.

Cement Backer Board: Refer to TCNA F144-21 tile installations, TCNA F250-21 stone installations and follow cement board manufacturer’s instructions.

WALLS: For non-sag and slip resistance; In a clean container, add approximately 5 quarts (4.7 liters) of clean potable water, then add the contents of the 50 lb. (22.68 kg) SikaTile®-550 Titan LHT Set. Mix thoroughly by hand or with a slow speed mixer to a smooth, thick, trowelable consistency.

FLOORS:  For use on floors or as a thin set; In a clean container, add approximately 5.75 quarts (5.4 liters) of clean potable water, then add the contents of the 50 lb. (22.68 kg) SikaTile®-550 Titan LHT Set. Mix thoroughly by hand or with a slow speed mixer to a smooth, thick, trowelable consistency. Mortar consistency shall be such that when applied with the recommended notched trowel to the substrate, the ridges formed in the mortar do not flow or slump. During use, stir mortar mix occasionally. Do not add additional water. Do not add latex liquid additives to SikaTile®-550 Titan LHT Set.

Read all installation instructions before installation. Choose a notched trowel with sufficient depth to achieve more than 80% mortar coverage and transfer to substrate and back of tile to both the tile and substrate for all interior applications, and more than 95% for exterior, commercial floor and wet applications, back-butter the tile to meet these requirements. With pressure, apply a coat of mortar by using the flat side of the trowel to key the mortar into the substrate. With the notched side of the trowel, apply additional mortar by combing it in a single direction parallel to the shortest dimension of the tile. Spread only as much mortar as can be tiled before the product skins over. Open time can vary with jobsite conditions. Set tiles firmly into the wet mortar and push the tiles back and forth in a direction perpendicular to trowel lines to collapse the mortar ridges and to help achieve maximum coverage.

MOVEMENT JOINTS:

All expansion, control, construction, cold, saw-cut, isolation, contraction, and seismic joints in the structure should continue through the tilework, including such joints at vertical surfaces, as specified per TCNA Method EJ171 or TTMAC Specification Guide 09 30 00, Detail 301MJ. Do not cover movement joints with mortar.

Product Curing time is affected by ambient and surface temperatures and humidity. Use the following as a guideline. Allow 24-48 hours before grouting and light traffic, and 7 days before heavy or vehicular traffic. As necessary, use plywood or other load distributing protection when moving heavy equipment across tiled assembly.

Clean tools and tile with water before the material dries.
