SGM Fast Set Thin-Set Mortar (Polymer Modified) is a latex-Portland cement mortar formulated to produce a rapid set time for the installation of ceramic, mosaic, pavers, quarry, and dimension stone (absorptive, semi-vitreous, and vitreous) tiles. This product enables an experienced tile setter to set and grout within two (2) to four (4) hours and open to traffic within six (6) hours. SGM Fast Set Thin-Set Mortar (Polymer Modified) is ideal for use in areas that require a minimum downtime or in cold temperature installation and tile repairs. The use of calcium aluminate cement and re-dispersible powder additives are used to accelerate set time, improve adhesion, provide greater bond strength, and resistance to impact or shock.
INSTALLATION
SURFACE PREPARATION
CAUTION
Product is alkaline on contact with water. Use paddle for mixing to avoid splashing into eyes or contact with skin. During mixing or application avoid contact with eyes. In case of such contact, flood eyes repeatedly with water and CALL A PHYSICIAN. Wash thoroughly after handling and before smoking or eating. Do not take internally. CONTAINS FREE SILICA — DO NOT BREATHE DUST. Prolonged exposure to dust may cause delayed lung disease (Silicosis). WARNING: This product may expose you to chemicals, including silica, which the State of California recognizes as a cause of cancer. For more information, visit the Proposition 65 Warnings Website (www.P65Warnings.ca.gov). Use NIOSH approved masks at all times to handle silica dust. KEEP OUT OF REACH OF CHILDREN.
MIXING
Add SGM Fast Set Thin-Set Mortar (Polymer Modified) powder to approximately ¾ gallon (2.85 L) cool, clean, potable water per twenty-five (25) lbs. (11.35 Kg) bag. Machine mixing with a slow speed drill and mixing paddle is preferred (250—350 RPM). Higher speeds are not recommended and will entrain air. Mix the two (2) components together thoroughly until smooth. The proper consistency is obtained when the mortar is applied with the notched trowel to the substrate and the ridges formed do not flow or slump. Allow the mortar to slake for five (5) minutes, and then re-mix before use. Do not add any additional water, latex, or powder after the mortar has slaked. Re-mix mortar occasionally during use and discard after initial set in bucket.
APPLICATION
Detailed installation procedures may be found in the TCNA Handbook and ANSI 108.5. All materials and effected areas should remain above 50°F / 10°C (fifty degrees Fahrenheit / ten degrees Celsius) or below 100°F / 38°C (100 degrees Fahrenheit / 38 degrees Celsius) 24-hours prior and 72-hours after placement. Apply mixed mortar liberally with the flat side of the trowel, using sufficient pressure to key into the substrate; then apply additional mortar with the notched edge of trowel leaving enough mortar to give 100 percent coverage with the back of the tile. Place tile while the surface is wet and tacky and spread mortar over an area no greater than can be covered with tile before the mortar skins over. Place tiles with a twisting motion and beat lightly before the initial set takes place to fully embed in the mortar. Mortar that has formed a skin should be re-troweled before applying tile. Some irregular tiles may require back-buttering. During the setting of tile, it is recommended to periodically remove a tile and check to see that sufficient transfer of mortar is being attained. Industry standards require a minimum of 3/32 inch (2 mm) mortar thickness after beat in. Do not adjust tiles after they have been set more than ten (10) to fifteen (15) minutes.
A ¼ inch gap shall be left around vertical abutments to allow for structural movement and filled with appropriate elastomeric sealant.
CLEANING
Use water to remove uncured mortar.
CURING AND GROUTING
The minimum cure is reached in twelve (12) to twenty-four (24) hours. Setting may vary according to atmospheric conditions. Normal grouting should be done forty-eight (48) hours later.
COVERAGE
Approximately:
SHELF LIFE
