Installation Use & Care Manual

To ensure a successful installation and proper adhesion, GBM has compiled the

following installation and setting material instructions. GBM will not provide any

guarantee implied or written for any product not installed in accordance with this

information. This is a general installation guide and may not represent the specific

installation guide of the product you purchased, for more details, please refer to the

product specific installation guidelines.

Due to the handmade nature of GBM glass tiles, variations in the shape, color,

shade and tone should be expected. Please inspect each box prior to installation

to verify lot consistency to assure acceptable shade variations.

IMPORTANT! READ before INSTALLATION!

Do not use any setting compounds such as mastics or epoxies that contain

petroleum distillates. Do not dilute admixtures with water.

GBM glass tiles can be installed on interior or exterior wall surfaces in wet or dry

locations. GBM glass tiles cannot be installed over flexible surfaces. They are not

recommended for floor applications (unless indicated for floor use) and should not be

exposed to extreme abrasion, thermal shock or extreme impact.

Although GBM glass tiles are designed to withstand a variety of potential hazards,

carefully place your tiles before setting to avoid surface scratches or scraping the back

of the tile with tools.

Proper installation and use of materials is required to avoid stress on the glass.

Proper installation requires that the substrate be dried and cured, and the walls be

properly rendered. Most concrete cures in approximately 28 days, depending on

atmospheric conditions and mix design.

Be sure to follow the recommended cure times as indicated by the Tile Council of

America handbook for tile installation.

INSTALLATION REQUIREMENTS

All materials should be used in accordance with manufacturers’ directions.

THINSET/MORTAR

INSTASET Instant Adhesive Mastic (WHSPSA-ROLL), a commercial grade heavy duty

thinset membrane may be used to adhere any tile/mosaic to the substrate. This method

allows for immediate grout application, eliminates problems with thinset shrinkage, and

acts as a tile crack isolation membrane. This installation method is also rated for shower wall installations. High performance, high polymer based non-sag thinset mortar - glue applied - with a trowel 1/4 in. x 3/16 in. V-Notch Trowel can also be used. Respect the deadline before grouting according to the mortar / glue chosen. Please follow the mortar manufacturer's guideline for actual recommended usage and applications.

Then, while holding the tile face up, separate the tile with a downward motion allowing the cut edge to sever the tile membrane. GBM glass tiles can also be cut with a wet saw. If using a wet saw, be sure to use a glass compatible diamond blade in good condition. A blade for cutting glass has smaller diamonds than a tile blade and has a continuous rim. Most blades designed for ceramic tiles are coarse and will chip the glass.
