S-400 LT (LOW TEMPERATURE) SETTING & GROUTING EPOXY

PRODUCT DESCRIPTION:

S-400 LT is a Tile Council of America formula AARII-HT, epoxy mortar and grout that meets or exceeds requirements of ANSI A118.3 and is USDA approved. S-400 LT is a two-part 100% solids epoxy formulation that allows installation to be completed at 30 degrees F.

S-400 LT has the same physical properties and chemical resistance as S-400.

S-400 LT is sag resistant and should be specified for setting or grouting ceramic tile on any wall or floor installation. This product has exceptional bond strength and will remain rigid and cohesive at temperatures up to 350 degrees F S-400 LT will resist attacks by many acids, alkalies and other chemical compounds that will normally break down cement mortars and grouts.

Floor brick, quarry tile, pavers and ceramic mosaics may be set and grouted with S-400 LT.

NOTE: When more stringent chemical resistance is encountered, S-4000 Furan or S-5000 high chemical resistant epoxy should be used.

USES:

S-400 LT is recommended when a quick-set formula is required in food processing plants, dairies, breweries, chemical laboratories, distilleries and refineries.

LIMITATIONS:

Surface temperature of substrate should be above 30 degrees F during tile installation. Continuous exposure of cured S-400 LT above 350 degrees F is not recommended.

TECHNICAL DATA Physical Properties:

INSTALLATION:

Substrate: S-400 LT is recommended for use on cured concrete, plaster, drywall, masonry surfaces, wonderboard and plywood. Substrate shall be prepared in accordance with ANSI A108.4. Surface to receive S-400 LT must be structurally sound, dry, free of sealers, coatings, oil, dirt and dust. New masonry surfaces should be sufficiently cured, dimensionally stable and free from cracks. It is advisable to brush all surfaces with a stiff brush to remove any loose material that may be encountered. Consult the Tile Council "Handbook for Ceramic Tile Installations" for specific setting descriptions.

Mixing: S-400 LT is furnished in 2 parts and exact proportions and thorough mixing of the parts with one another is absolutely essential for satisfactory curing and performance. Empty contents of Part A (liquid portion) into mixing bucket, add Part B (solids portion) gradually and mix thoroughly using either hand tools or a slow speed power mixer. Care should be taken to avoid whipping air into the mix. Mix until smooth and free of lumps. It is highly recommended that complete units be mixed, however, if necessary to split a unit, weigh out 3 parts of Part B to 1 part of Part A. Clean tools with warm water immediately after use.

Working Characteristics: S-400 LT is ideally installed at temperatures from 32 degrees to 50 degrees F. At higher temperatures, the pot life, open time and clean-up time are reduced; however, it is more fluid and easier to work. At lower temperatures these factors are reversed. Working surface temperature can vary from room temperature and should be taken into consideration. Do not begin application of S-400 LT until the temperature of the room and substrate is above 30 degrees F and rising. Maintain a temperature of 30 degrees F or higher during the curing period.

APPLICATION:

As a Setting Mortar: Spread mixed S-400 LT with a notched trowel, then set tile. Use a 1/8" notched trowel for ceramic mosaics to achieve a 1/16" bed. Use a 1/4" notched trowel for smooth or shallow ribbed pavers providing a finished bed of 1/8". Use a 1/4" x 3/8" square notched trowel for heavy ribbed backed tile such as Quarry Tile.

Full coverage of the setting material on the back of the tile is desirable to prevent broken and cracked tile. The National Tile Contractors Association recommendation to accomplish full coverage is as follows: Apply mortar to substrate using the flat side of the trowel to fill any voids and "key" the material to the substrate. Using the proper sized notched trowel, comb the mortar evenly in one direction only. Do not "swirl". Set the tile in the mortar with the edge of the tile parallel to the comb lines. To remove air voids, push the tile back and forth in the mortar perpendicular to the comb lines.

Once the S-400 LT begins to set, it should be discarded, as proper bonding will not be accomplished. Allow 16 hours to elapse before grouting tile.

As a Grout: With a firm, straight edge rubber trowel (Grout Master) force as much S-400 LT into joints as possible, using sufficient pressure and flow to avoid air pockets or voids. Before the S-400 LT loses its plasticity, remove excess with rubber trowel in a squeegee fashion working diagonally to joints to facilitate removal without pulling material from joints. For final clean-up, use Scotch-Brite pad and a minimum amount of water. Water with a small amount of mild soap added will speed clean-up. Clean completely, as S-400 LT is difficult to remove after it begins to set.

CAUTION:

Protect from all traffic for 10-12 hours, heavy traffic for 24-48 hours.

PROTECTING NEW TILEWORK:

To avoid damage to finished tilework, schedule floor installations to begin only after all structural work, building enclosure, and overhead finishing work, such as ceilings, painting, mechanical and electrical work are completed. Keep all traffic off of finished tile floors until it has fully cured, or provide up to 3/4" thick plywood protection over Kraft paper to protect floors before installation materials have fully cured.

COVERAGE:

CLEAN-UP:

Final clean-up, use Scotch-Brite pad and plenty of cool to warm (not hot) water.

COLORS:

#961 Gray, and #991 Black.

PACKAGING:

S-400 LT is available in 1 and 3 gallon sizes.

SPECIFICATIONS:

Material: Setting mortar and tile grout shall be S-400 LT, a two-component mix consisting of specially graded silica aggregate (#7 on M.O.H. Scale of Hardness), color-fast pigments, a special blend of fast-acting hardeners and liquid epoxy resin, and be free of water and organic solvents; as manufactured by Summitville Tiles, Inc., Summitville, Ohio.
