Limitations
Not for installing green marble or other moisture-sensitive stone tile; use TEC Skill Set Marble Mortar. For non-green marble tile applications, use white thin set mortars. Not for use over rubber, strip wood floors, oriented strand board, particle board or lauan plywood. For CDX plywood, use TEC Skill Set Mortar Additive with TEC Skill Set Floor & Wall Mortar. Do not apply over single-layer wood floors. Certain natural stone tiles may be affected by mortar shadowing or staining. Test a small area prior to use to determine suitability.

Surface Preparation
All substrates must be dry, structurally sound with maximum deflection per industry standards of L/360 for ceramic tile installations and L/720 for natural stone installations under all live and dead loads; and be free from oil, grease, dust, paint, sealers or concrete curing compounds. All contaminants should be removed prior to installation of tile. Surface protrusions and tile glazes shall be removed by sanding, scraping or scarifying. After preparation, remove all dust by vacuuming. Note: Vinyl asbestos tile or any substrate containing asbestos shall not be sanded, scored or scarified because of the potential health hazard of breathing dust. Any substrate containing asbestos must be handled in accordance with existing EPA regulations. Contact your local EPA office.

 

Notes: Expansion joints must be provided in the tile work over all construction, control and expansion joints in the backing and where backing materials change. Follow ANSI A108.01 Section 3.7 Requirements for Expansion Joints.

Maximum variations in all substrates must not exceed 1/4" in 10 ft. (6 mm in 3 m) or 1/16" in 1 ft. (1.5 mm in 0.3 m) from the required plane. For non-level, interior surfaces use TEC® Skill Set™ Self Leveling Underlayment.

 

Mixing
For best results, maintain all tiling materials, substrates, room and adhesives at 50°-70°F (10-21°C) for 24 hours before and 48 hours after installation. Avoid breathing dust and contact with eyes and skin. Avoid using high speed mixing, not to exceed 300 rpm, to prevent entraining air. Add powder to liquid for ease of mixing.

In a clean mixing container, slowly add product to clean, cool, water as specified in the chart below.

Size Water
25 lbs. (11.34 kg) 2.5-3 quarts (2.37-2.84 L)
50 lbs. (22.68 kg) 1.25-1.5 gallons (4.73-5.68 L)

Mix material for 2-4 minutes to a thick creamy consistency. Use immediately.

 

Application
Apply mortar using flat side of trowel to promote better substrate contact, then comb in one direction with the notched side of the trowel. Spread only an area that can be tiled while surface is still tacky (typically 10-15 minutes). Press tiles into setting bed, then push in a direction perpendicular to the notched trowel ridges to achieve optimum coverage. Apply mortar in a heavy enough layer so that complete contact (no voids) between mortar and tile is accomplished when tile is positioned. It may be necessary to "back-butter" large tiles to achieve complete coverage and firm support. Periodically remove and check a tile to assure proper coverage. Keep a minimum of 2/3 of the joint depth between tiles for grouting.

Open time and tile hand adjustability may vary with job site conditions. Stir occasionally during use to maintain the smooth, creamy consistency of the product. Do not add additional water.

 

Drying Time
Grouting may be accomplished when tiles are held firmly in place, typically 21/2 to 3 hours after installation is completed. No traffic is permitted over the tiles prior to grouting. Cold temperatures or high humidity may extend curing time. Unglazed tiles may require sealing prior to grouting so discoloration will not occur. The use of TEC grout products are highly recommended. DesignColor™ Grout mixed with Grout Boost® Stain Resistant Grout Additive or Power Grout™ are available in a wide array of designer colors, these products provide stain resistance, high performance and ease of use.

 

Clean-up
Clean tools, hands, and excess materials from face of tile, while mortar is still fresh, with warm soapy water.
