Installation & Assembly

2. Various kinds of Wallboards - Walls of this type must be firm, with no warping or

"give". "Dry wall" should be waterproofed if it is not already.

3. Plywood - Ensure that plywood is clean and without imperfection

4. Smooth Concrete - Ensure that concrete is clean and without imperfection

5. Tiled or others - Removing existing tile needs professional treatment. Talk to your local

glass mosaic dealer or other professional tile installers.

Any painted walls must be well scratched to have a better adhesive effect. These walls are ready

to receive tile when the surface is CLEAN, grease and soap free, WATERPROOF, DRY and

FLAT, with no loose particles of paint, plaster, dust, etc. This may require washing, sanding,

scraping or filling.

The performance of a properly installed thin-set tile application is dependent upon the durability

and dimensional stability of the substrate to which it is bonded. The following recommendations

are from the Tile Council of America (TCA) Handbook for Ceramic Tile Installation 2002

(www.tileusa.com) and are general in nature. Please reference the specification that applies to

your project.
