INFORMATION & GUIDELINES FOR THE INSTALLATION OF PILLOW GLASS

RECOMMENDED INSTALLATION

Pillow Glass mosaics are designed for almost any commercial and residential interior and exterior

application including walls, ceilings, water features, countertops, backsplashes and more. It is not

recommended for areas that may be subject to heavy impact, heavy abrasion, and areas where

temperatures can exceed 130 degrees Fahrenheit. This product is not suitable for floor

applications.

There will be some variation in size and surface shape between each pillowed square, this

variation is considered to be a desired feature in the Pillow Glass.

NOTE: this document contains only guidelines for the installation process. A professional installer

should always be consulted to discuss the specific parameters surrounding your project.

CURVED SURFACES

SOLISTONE Pillow Glass mosaics can be installed around gently curved surfaces. Some

manipulation of the tiles may be required in order to create uniformity between each sheet. The

glass comes with a plastic front or mesh back which can easily be cut with a utility knife.

SUBSTRATES

All substrates should be firmly fixed, flat, clean, dry and free of contaminants such as dust, oil,

paint, sealers etc. to ensure proper adhesion. Painted surfaces must be scuffed or sanded for the

product and adhesive to bond correctly. Wet areas need special attention and require

appropriate substrates, e.g. concrete, cement boards (compressed sheet), and/or treated

plywood. The use of reinforced waterproof membranes is suggested.

WATERPROOF MEMBRANES

Waterproof membranes prevent leakage of water through to the sub-floor framing and/or

habitable spaces below. Particular attention must be paid to: carrying the membrane up the wall,

outside shower boxes, installation of bond breakers, and sealing around penetrations. It is

strongly recommended that membrane systems be used in all wet areas. Some systems may

involve the use of a primer.

CUTTING

The glass can easily be cut with a curved splitting clamp or a glass cutter. The mesh back or

plastic front can easily be cut with a utility knife. To create a more seamless look the glass

pebbles can be removed from the mesh by hand and readjusted if necessary.

ADHESIVE Follow the adhesive manufacturer’s instructions carefully. We do not recommend one brand of adhesive over another. Please check with your local tile supply store for alternative and comparable products. The manufacturer's literature will explain if the adhesive product is suitable for interiors and/or exteriors, as well as walls and floors. Most thinset mortars with a latex additive (multi purpose and polymer modified thinsets) are adequate for installing glass.

GROUTING Grout should be designed for external or internal conditions, whichever may be the case. Nonsanded grout is generally recommended for any grout joint 1/8” or smaller. Grouts are ordinarily a water mix but where some flexibility may be needed, a latex additive or similar product should be used. It is important to wait the interval recommended by the adhesive manufacturer before grouting to minimize dirt ingress between the squares and avoid the opportunity for dislodging.
