INSTALLATION:
The following recommendations comply with the 2006 TCNA (Tile Council of North America) Handbook Guidelines.

RECOMMENDED SUBSTRATES
Well cured mortar beds-ANSI A108.1B (cured a minimum of 7 days).
Cementitious backer units(CBU) ¨CANSI A118.9 (Note: An ANSI A108A-2.1.8 membrane is required behind all CBU installations in wet areas. Concrete slabs (on grade) cured for 28 days minimum. Gypsum board (dry areas only)-ASTM C 1396 or ASTM C1396M-04.

NOTE: Directly bonding glass tiles to wood substrates is not recommended.
All surfaces to receive tile shall be left clean, and free of dust, Oil, grease, paint, tar, was curing agent, sealer, adhesive residue, form release agent or any oother deleterious substance and debris which may prevent or reduce adhesion.

Glass tile high expansion and contraction requires the installation of movement joints per EJ171-5, page 68.

SETTING MATERIAL
We recommend any high grade flexible mortar system (latex modified) as a setting material for mosaic glass tiles. For grouts, a premium polymer-modified unsanded grout for joints from 1/16¡± (1.5mm) to 1/8¡± (3mm) wide. For grout lines larger than 1/8¡± (3mm) wide use sanded grout.

INSTALLATION
1. Mix setting materials according to manufactures¡¯ instructions.
2. Apply setting materials to the substrate using the notched side of a 3/16¡±x5/32¡±x3/16 V-notched trowel.
3. Using the flat side of the trowel, smooth out all ridges to achieve a consistent, even 1/8¡± thick coverage.
4. Apply glass mosaics to the freshly troweled material with the PAPER-SIDE OUT.
5. Using a rubber float or equivalent tool, gently press the tile into the adhesive and flatten sheets to each oother to insure complete contact. Do not push the sheet too deeply into the setting materials, as to cause the setting materials to ooze up between the spaces between the tile
6. Adjust tile sheets for correct alignment and even spacing between sheets. Do not allow setting material to dry or skin over before completing this process.
7. Allow sufficient time to set prior to removing paper (approximately 20-30 minutes).
8. Using a wet sponge, apply warm water to the paper to soften the glue, allowing the paper to release. Avoid using too much water, Gently peel back the paper.
9. Clean all excess setting material with a damp sponge, Clean all excess setting material that may have remained on the tile surface. Wipe away any haze that may have remained behind.
10. After 24 hours, mix grout, following manufacturer¡¯s instructions.
11. Grout openings between tiles and sheets.
12. Clean all excess grout immediately with a damp Sponge.
13. Polish off any remaining haze with a dry cloth or towel.
14. After grouting, protect area from light foot traffic and light water exposure for at least 72 hours. Protect area from heavy traffic and regular use for at least 7 days.
