Most commonly used in resin bound gravel mixes, this finely graded (0.2-0.36mm) sand is kiln-dried to ensure the lowest moisture content possible to reduce the risk of reaction with polyurethane resin binders. It can be added to the mix in a forced action mixer or sprinkled over the upper surface when still tacky. THe Chelford 52 sand can help to further improve the strength of resin bound gravel surfacing or add texture to provide an anti-slip surface. This can be most useful when laying a resin bound gravel driveway which is on an incline to prevent tyres or feet from slipping on the surface.
Typical applications require one 6.25kg bag to be used per 100kg resin mix and will add anti-slip to approximately 3.3m? when the resin bound gravel mix is laid at a depth of 18mm.
