Glass Surface Applications

Description 

Glass feature surfacing is a thermal set 2-part UV stable polyurethane resin blended with a design mix of crushed or beaded recycled glass (typically 8mm-10mm) to create a continuous surfacing system. 

Uses 

Glass surfacing is ideal for interior and exterior glass paving, stunning highlights, and logos. These applications can also be used in conjunction with Interior Stone Surfacing.

Suitable Surfaces 

These applications are designed to be overlaid on concrete, asphalt and timber floors in addition to balconies, podiums, etc. For more details, you can refer to the Overlay of Concrete, Timber flooring and Asphalt Specification Advice Sheets or Permeable Pavement Specification Advice Sheets. 

Safety 

Essential safety details are provided by the Material Safety Data Sheet, which recommends wearing basic equipment like gloves, goggles, overalls, and safety footwear. 

Surface Preparation 

All areas to be treated with crushed glass paving should be clean, dry, and free from oil, grease, vegetation, chewing gum, loose matter and all other contaminants that may impair the adhesion of the binder to the substrate. All new concrete substrates must be subjected to a minimum curing period of 28 days and primed with Rockseal Concrete Primer. 

Mixing 

A cement mixer is required to blend the bagged aggregate. The part A and B resin is then mixed in a separate mixing vessel using an electric drill and paddle. Resin mix is then added to the cement mixer and combined with the aggregate. Once mixed, the crushed glass paving materials are dispensed to a wheelbarrow and taken to the work site ready for trowelling. 

Storage 

All resins and aggregates for Glass Feature Surfacing applications must be stored in a clean and dry environment. Refer to storage instructions and use-by date on your kit for specific details on how to best store your leftover materials. 

Application 

Glass paving installations are applied with hand trowels by trained and accredited applicators. The mixed material is dispensed, and an asphalt rake, lute or gauge rake may be used to assist in evenly spreading the material. Material should be compacted with trowels to provide an even consistency and level. The trowel should be regularly wiped clean to avoid resin build up and to achieve best results. At this stage, when required, dust with glass for anti-slip finishes. Repeat process to completion. Do not walk on surface until completely set and tack free. Do not traffic surface with vehicles for 3 days. 

Clean Up 

To clean and maintain your interior and exterior glass paving, you should use mineral spirits to effectively remove dirt, grime, and debris. 

Coverage 



Technical Data 

Standard Pack Size 

A standard package for glass paving includes a 100kg kit of Resin and Aggregate. Other kits are available to provide greater amounts for larger areas of coverage. 

Cure Time 

Standard-grade resin pavement requires 3- 5 hrs at 20ºC to effectively cure and form a strong bond. Other grades of resin pavement may require more time to cure.
