Application Types
A-Grip UV has been developed for use as a high performance, decorative paving system. Commonly used on driveways, pathways, patios, conservatory & pool surrounds, access roads and both commercial and domestic exterior surfacing applications.
Method of Application
A-Grip UV is mixed with an approved blend of washed, dried decorative aggregates and then trowel applied on to a suitable substrate. The applied screed will then cure to produce a highly decorative, hardwearing, porous surface.
Packaging and Mix Ratio
A-Grip UV is supplied as a pre-measured, 6.5kg two component kit that should be mixed with a 100kg blend of approved aggregates (6% resin to 94% aggregate). Component ‘A’ is supplied in a 5Ltr plastic bottle and component ‘B’ is supplied in a 3Ltr white plastic bucket. A-Grip UV+ is available as a 7.5kg kit size (7% resin to 93% aggregate) however all performance standards and tests are based on the standard 6.5kg kit size.
Coverage Rates
The coverage rate of A-Grip UV is dependent upon the selected aggregate blend and required application depth. As a general ‘rule-of-thumb’ the average coverage rate for a single kit (100kg of aggregate) mix laid at a minimum 20mm depth is 3.30m². The following table details the coverage rates of our approved aggregate blends at varying application depths.

Aggregate Selection
A-Grip UV must only be used with the aggregates specified in the ‘Approved Aggregates’ document. All aggregates are tested for performance, specially washed and dried for use with a decorative bound resin. It should be noted that different aggregate types can provide very different performance standards. The A-Grip UV approved aggregates and blends have been tested to ensure the desired appearance provides suitable performance for the required end use. All our aggregates can be purchased and delivered with the A-Grip UV resin. We do not recommend the use of any non-approved aggregates or blends.
A-Grip UV Curing Times
| Initial cure @ 22°c (Unworkable) | 30-60 minutes |
| Surface cure @ 22°c (Fit for Foot Traffic) | 12-24 Hours |
| End cure @ 22°c (Fit for Full Traffic) | 24-48 Hours |
| Full Cure @ 22°c (Maximum Strength) | 5-7 Days |
Substrate Suitability
The following table details the minimum application depths for A-Grip UV resin bound surfacing and the underlying base types. For a more detailed breakdown of suitable substrate specifications please consult the A-Grip UV specification and installation guidance documents. Our advised penetration value (pen number) for bitumen (BS4987) and hot rolled asphalt substrates (BS EN 13108) is 70-100. Any pen value greater than 100 is
potentially at risk of softening in extreme temperatures whilst any pen value exceeding 150 would be too soft and result in reflective cracking.
