Most commonly used in resin bound gravel mixes, this finely graded (0.2-0.36mm) sand has been kiln-dried to ensure the lowest moisture content possible. It is dried to help reduce the risk of reaction with a polyurethane resin binders. Either added to the mix in a forced action mixer or sprinkled over the surface when it’s still sticky, 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 or pathway on an incline to prevent tyres and people from slipping.
When used traditionally, we estimate that one 6.25kg bag can be used per 100kg resin mix and this will an anti-slip quality to a 3.3m² resin bound gravel area when laid at 18mm deep.
