Aggregate Stone Binder - Non UV Resin 6.5Kg kit, 2 Part system for Resin Bound Aggregates.This two Part kit is to be used when laying Decorative Aggregates for areas like Driveways, Patios and Paths.
Polystone ARO is the standard grade of stone binder. This grade is not UV stable and will gradually give the finished screed a permanent golden/honey coloured hue over the first few months after installation. As a consequence it is best to limit this product to use with buff/yellow/golden/brown aggregates like Golden Pea or Golden Quartz. Red Granite seems to complement Polystone ARO well and Green Granite gives a dark almost black appearance as the resin matures.
It is recommended that before using unfamiliar aggregates, installers should trial the screeds by making sample slabs and leaving them outside in a sunny aspect for a few months so the final effect can be realized.
This Kit should be used with 100KGS of Decorative Aggregates to give you a surface area of 3 M squared at 20mm deep.
Most installers will use a 75% of 2-5 mm aggregate with
25% of 1-3 mm aggregate. 5% coarse silica sand or fine ground glass can be added to the screed during mixing to help with the anti-slip properties of the finished installation. Adding these fines to the mix is preferable to broadcasting them as
it is difficult to broadcast the fines evenly. This can lead to
a variation in appearance on the surface of the screed which appears to the eye as shade differences across the surface.
