Stonblend GSI is a nominal 3/16 in./5 mm flooring system that offers a cost-effective alternative to ter­razzo. It combines decorative looks with excellent chemical and wear resistance and cleanability. Its surface provides a moderate degree of slip resistance while remaining resistant to staining, marring, and yellowing. It is comprised of:

A two-component, penetrating, UV resistant epoxy primer

A three-component, troweled mortar consisting of epoxy resin, curing agent and colored quartz silica aggregate

A two-component, clear, UV resistant epoxy sealer

A two-component, clear UV resistant, leveling epoxy sealer

A two-component, non-reflective, waterborne, aliphatic polyurethane coating

Applications vary from light manufacturing, such as food and pharmaceutical processing, to laboratories, hallways, offices and holding areas in healthcare, educational and correctional facilities. Its easy-to-maintain, low gloss finish enhances Stonblend GSI's appeal wherever functional, attractive flooring is required.

Stonblend GSI, in conjunction with its appropriate primer, is suitable for application over properly prepared concrete, wood or steel surfaces. Not recommended for use over asphalt, mastic, gypsum based products, brick or painted surfaces. These must first be removed by mechanical means to expose the substrate prior to priming and overlay-ment.

To ensure that the entire system is watertight, the use of Stonhard's Stonproof ME7 membrane system is required with strict adherence to application instructions.
