- Installation
All installations must be set in accordance with the most recent publication of the Tile Council of North America’s “TCNA Handbook for Ceramic, Glass, and Stone Tile Installation” and the following guidelines.
Approved Substrates
Properly prepared concrete, concrete block, plumb and true masonry, gypsum board, cement backer board, cured Portland cement beds and exterior grade plywood (primed, interior floors only).
Do Not Use Over: Hardwood, masonite, chipboard, flakeboard, presswood, asbestos board, vinyl flooring, lauan plywood, OSB, metal, gypsum-based levelers, glass, plastic or other similarly unstable substrates.
Note:
Not for use with Green Marble or similar moisture sensitive tiles prone to "curling".
When installing over exterior grade plywood the surface must be first primed with Super-Weld.
Carpentry Requirements For Plywood Floors (Interior Only):
1) Installation requires two layers of APA exterior plywood, underlayment grade or better, with a minimum total thickness of 1 1/4". Fasten layers with screw nails located 6" centers along plywood edges and 8" centers each way throughout the sheet.
2) The subfloor must consist of a minimum of 5/8" exterior plywood or 1" nominal boards over bridged floor joists 16" on center with a maximum deflection of 1/360 of the span.
3) The top layer must consist of a minimum of 5/8" exterior plywood with offset end and edge joints at least two inches from the subfloor joints.
4) Leave a 1/8" to 1/4" space between top layer sheet edges and all materials they about such as walls, drains, posts, etc. These joints should be filled with the setting mortar when tiles are being installed. Adjacent edges of plywood must not be more than 1/32" above or below each other.
5) Install plywood with rough or knotty side exposed to enhance mechanical adhesion of thin-set mortar to plywood.
6) Prime all plywood surfaces to be tiled with Super-Weld. Apply Marble Master when primer has dried to touch.- Mixing
1) For a 25 pound bag pour approximately 1 gallon of cool, clean water into a clean mixing container.
2) Gradually add powder while slowly mixing using a slow speed bucket mixer or mortar box. Do not use high-speed drills.
3) Continue mixing for about 3-5 minutes or until the mixture becomes a thick, smooth, paste-like consistency.
4) Allow mixture to slake (stand) for 10-15 minutes.
5) Then remix 1-2 minutes before applying.
Note: Mixture should be stirred occasionally during use, do not retemper. Pot life is approximately 1-2 hours depending on temperature and humidity.- Application
All surfaces must be clean and free of dust, grease, wax, and foreign matter. Using pressure, apply a thin skim coat with flat edge of trowel. Then using the proper sized notched trowel apply a second coat to form ridges. Trowel only in an area that can be tiled before the mortar skins over (15-20 minutes). If mortar skins over, remove and apply fresh mortar. Apply dry tiles with pressure and a slight twisting motion. Immediately beat tiles in to ensure maximum contact and bond. After setting several tiles, remove one or two and inspect, making sure tile backs are 100% covered with mortar. Back buttering of tiles may be necessary to insure 100% coverage. Do not use at temperatures below 45°F (7°C) or above 95°F (35°C).
Grouting
May be accomplished in 24 hours if tiles are firmly set and kneeling boards are used. To ensure quality joints, use one of Super-Tek’s high performance grouts.

Technical Details & Test Data
- Curing
All traffic should be kept off of floors for a minimum of 48 hours. Jobsite temperature must remain between 45°F and 95°F for a minimum of 72 hours after installation.

Packaging & Availability
- Packaging
25 lb. (11.5 Kg.) multi-wall paper bag, available in white
Coverage
Marble and ceramic mosaics: 3/16" x 3/16" V-notched (saw tooth) trowel. Approximate coverage 50-55 sq.ft. per bag.
Marble, granite, stone and ceramic tiles up to 6"x6" in size: 1/4" x 1/4" x 1/4" Square-notched trowel. Approximate coverage 35-40 sq.ft. per bag.
Marble, granite, stone and ceramic tiles (including lug-backed tiles) up to 12"x12" in size: 1/4" x 3/8" x 1/4" Square-notched trowel. Approximate coverage 25-30 sq.ft. per bag.
Note: When installing tiles larger than 12"x12" use appropriate size trowel to ensure 100% coverage of tile back (i.e. 3/4" U-notched trowel). Coverage will vary.
Storage & Handling
- Shelf Life
One year when stored in original packaging in a dry, ventilated place. Exposure to moisture will shorten the shelf life.
