How do I prepare a concrete floor for a thin-set application?


Make sure that the existing concrete is clean, dry, structurally sound and free from any bond breaking or bond inhibiting materials. Bond inhibiting materials can include, but are not limited to, sealers, waxes, oils, curing compounds, dirt, grease, form release agents, paint, old adhesives, laitence, etc... If these materials are present on the concrete, they must be completely removed prior to any direct bond installations of tile or stone. Additionally, the industry tolerance for substrate flatness is to have variance no greater than ¼” (6mm) in 10 ft (3m). Use a LATICRETE® self-leveling underlayment (e.g. NXT Level Plus), patching material (e.g. NXT Patch or thick bed mortar (e.g. 3701 Fortified Mortar Bed to bring the surface to within required tolerance.

What is the proper construction of plywood floors and what do I use to install tile over exterior glue plywood floors?


The following is the criteria for the proper construction of interior tiled plywood floors:

The total plywood thickness must be a minimum of 1 1/4" (32mm) thick. The subfloor (bottom layer) must be tongue and groove. Either 3/4" (19mm) thick or 5/8" (16mm). For the 3/4" (19mm) subfloor, use a minimum of 1/2" (12mm) underlayment. For the 5/8" (16mm) subfloor, use a minimum of 5/8" (16mm) underlayment.

The subfloor and underlayment sheets must be installed perpendicular to the joists. Leave an 1/8" (3mm) gap between the sheets. You must use and exterior glue type of plywood (CDX) for the underlayment. Douglas fir will provide the best results. See LATICRETE Technical Data Sheet (TDS) 152 "Bonding Ceramic Tile, Stone or Brick Over Wood Floors" for more information on other types of suitable underlayments. The plywood must be fastened a minimum of every 6" (150mm) at the perimeter and every 8" (200mm) in the field. Wafer head galvanized screws provide the best results. The floor joists must be no farther apart than 16" (400mm) on center. They must be a minimum of 2" x 10" in size (50mm X 250mm).

Verify that the wood floor does not exceed the maximum standard for deflection called for by International Building Code (IBC) for commercial installations, International Residential Code (IRC) for residential installations or the applicable building code, historically L/360 under combined live and dead load has been used for ceramic tile. L/480 under combined live and dead loads has been used for stone and agglomerate stone. Simply put, if the floor bounces too much, the tiles can crack and come loose, or the grout can crack and/or powder out.

For best results, use 254 Platinum, 257 Titanium or MULTIMAX™ LITE to install tile directly over exterior glue plywood. LATICRETE TDS 152 "Bonding Ceramic Tile, Stone or Brick Over Wood Floors" gives an overview on the proper construction of plywood floors.

Can I install tile or stone in a swimming pool or other water feature?


Yes. Tile or stone is ideal for use in swimming pools, fountains, spas, and other water features when using LATICRETE products. Since pools and water features are required to hold water, it is always a good idea to install a waterproofing membrane on the substrate to help prevent water loss and to maintain the integrity of the vessel. Please refer to the LATICRETE Tiled Swimming Pools, Fountains and Spas Technical Design Manual for complete information on tiling and maintaining these installations. Allow the tile or stone installation system to sufficiently cure prior to filling pool, fountain, spa, or water feature with water (as stated in TDS 192 "Installation of Ceramic Tile in Swimming Pools"). The LATICRETE products listed below are ideal for use in submerged installations or in steam rooms.

Which LATICRETE products can I use to install tile or stone over a poured gypsum underlayment?


Since gypsum based products are sensitive to water/moisture and can also develop hairline cracking, LATICRETE would recommend the use of a waterproofing/crack suppression membrane (e.g. HYDRO BAN® or 9235 Waterproofing Membrane) over the poured gypsum underlayment prior to installing the tile or stone. LATICRETE waterproofing or crack suppression membranes may be installed directly to the poured gypsum underlayment ONLY if the poured gypsum underlayment has been treated with the underlayment manufacturer's over-spray product. If no over-spray product has been applied to the underlayment, it would be necessary to skim coat the surface with a 1/8" (3mm) thick application of a LATICRETE latex fortified thin-set mortar (e.g. 254 Platinum). The skim coat must be allowed to dry for a minimum of 24 hours prior to the application of the waterproofing/crack suppression membrane. Tile or stone can be installed with a latex fortified thin-set mortar (e.g. 254 Platinum) or an epoxy adhesive (e.g. LATAPOXY® 300 Adhesive) when required. Please note that poured gypsum underlayments are for interior use only!

Which LATICRETE products can I use to install paper-face mounted glass mosaics?


Check with the glass mosaic tile manufacturer for specific installation material requirements for their glass. If latex-based thin-sets are recommended then choose from either of the following methods (as per ANSI A108.14 and ANSI A108.15);

For the conventional two-step process of thin-setting and grouting, use Glass Tile Adhesive Mortar, 254 Platinum (white), or 257 Titanium (white).

For glass mosaic tile which requires an epoxy setting material, use LATAPOXY® 300 Adhesive.

As always, it would be wise to conduct a test area (under actual jobsite conditions) with the intended installation materials to determine suitability and acceptability of the installation system as well as the final appearance.

Which LATICRETE products can I use to install rear mesh mounted glass mosaic tile?


There is currently no industry standard for the glues and meshes used on the back of mosaic tile. In some cases, these glues and/or mesh mountings are sensitive to moisture and alkalinity exposure. Unless the glass manufacturer states, in writing, that the glue and mesh are suitable for installation with a latex fortified cement based adhesive, LATICRETE would recommend the use of a 100% solids epoxy adhesive (e.g. LATAPOXY® 300 Adhesive).

However, ANSI A137.2 "American National Standard Specifications for Glass Tile" states that the minimum shear bond strength for glass tile, tested after 28 days dry, should be 150 psi (1 MPa). When tested after 21 days dry and 7 days submerged the minimum shear bond strength should be 100 psi (0.7 MPa). This standard also states "For back-mounted or edge-mounted assemblies, the glass manufacturer must clearly and definitively state areas of use for which mounting assembly is suitable and warranted." - ANSI A137.2 5.2.2.1.10.2

My thin-set mortar is setting up too fast, what can I do?


It is important to read product data sheet for pot life and open time, based on conditions, for the particular product(s) being used. Understand that hot temperatures will accelerate the cure time, shorten pot life and minimize open time of any adhesive. The basic rule is that for every 18°F (10°C) above 70°F (21°C), a cement based adhesive or grout, and an epoxy based adhesive or grout, will cure twice as fast.

If the mortar in the bucket is beginning to get hard, you may be able to remix the mortar DO NOT ADD WATER!! to redistribute water throughout the mix. If the mortar is too hard, it will be necessary to discard the unused material and mix a new batch.

Some useful hints for hot conditions can be found in LATICRETE TDS 176 "Hot Weather Tiling and Grouting" found at https://laticrete.com.

Which adhesive should I use for porcelain bodied tiles?


Use a high strength latex fortified thin set mortar to install porcelain tiles. (e.g. 254 Platinum, 257 Titanium or, MULTIMAX™ LITE, etc...). Porcelain tiles are very dense and typically have a porosity rate of ≤0.5%. These tiles require the high bond strength that high-performance fortified thin set mortars provide. Please keep in mind that the Tile Council of North America (TCNA) requires the use of latex fortified thin set mortars for the installation of porcelain tiles.

Can I install a mesh-backed or resin-backed stone or agglomerate stone?


Yes. It is important to note that the adhesion of the mesh and/or resin backing to the stone or agglomerate stone is equally, if not more important than the adhesion of the tile adhesive to the mesh and/or resin backing. If the adhesion of the mesh and/or resin backing is minimal, it is very possible that the stone or agglomerate stone can come loose while the mesh and/or resin backing remains bonded to the substrate. Some mesh adhesives may be moisture sensitive and should not be used in certain applications. Check with the stone supplier or agglomerate stone manufacturer for recommended uses and applications.

Consult with the stone supplier or agglomerate stone manufacturer for their recommended installation instructions. To ensure maximum adhesion and performance use LATAPOXY® 300 Adhesive for any mesh and/or resin-backed stone or agglomerate stone.

It is always a good idea, and highly recommended, to conduct a test area (under actual job site conditions) with the specified installation materials, to determine acceptability and suitability of the system.

Which adhesive should I use to install Saltillo tiles?


Use a high strength latex fortified thin set mortar to install Saltillo tiles. (e.g. 254 Platinum, 257 Titanium, or MULTIMAX™ LITE, etc...). Saltillo tiles are very porous and highly absorptive which can quickly draw moisture out of conventional dry-set (ANSI A118.1) thin set mortars. High performance, latex fortified thin set mortars provide a longer working time as well as better adjustability time. Additionally, the moisture should not be drawn out of a latex-foritfied thin set mortar as quickly. This will result in higher bond strength and make the Saltillo installation much more durable.
