The non-UV-stable grade of Addaset. Identical performance in every respect except that the resin darkens under UV. Specify it only where the colour shift is acceptable or the area is sheltered.
Where it is used
Sheltered pedestrian areasAreas where a darkening resin is acceptable or intendedBudget-driven driveway and patio work
Substrates
Concrete — clean, dry, free of laitance, oil, grease and loose particlesAsphalt — clean and dryJoints reflected through the surface
Application data
Coverage, thickness, mix and cure, as declared by the manufacturer. Site conditions in the Gulf sit at the top of most of these ranges — allow for it in the programme.

Where not to use it
The limits are as much a part of the specification as the performance. Everything here is stated on the manufacturer's data sheet.
The resin will darken when exposed to UV — this is inherent, not a defectApplication range is narrower: +5 °C to 25 °CDo not apply in wet conditions
Specification clause
Resin bound surfacing: Addagrip Addaset Non UVR polyurethane resin bound surface course, [10] mm aggregate laid [22] mm thick to the approved sample panel. Contractor to advise the Architect in writing that the resin darkens under UV exposure. Permeability to BS EN 12697-40:2005. Applied between +5 °C and 25 °C. 7 days full chemical cure.
Square brackets mark the choices that belong to the project. Send us the finishes schedule and we will return the clause completed, with the sample and mock-up programme against it.
Documents
