What is the Resin Bonded System?
The Resin Bonded system uses a durable polyurethane resin which is applied to Concrete, Tarmac, Wood or Metal to bond the washed and dried aggregate to the surface. This system provides a loose gravel appearance without the common trouble of stone migrating along paths and into houses.
Available with a 2-5mm or a 1-3mm sized aggregate, this system offers a high friction finish suitable for patios and pathways. Unlike the BoundWorx® Resin Bound system, resin bonded surfaces are not smooth or permeable, but the traction provided by the bonded aggregate makes it a great choice for disabled access areas where greater grip is required.
The surface to be laid on must be clean, dry, and structurally strong enough for the intended use. New surfaces should be left for a minimum of four weeks for moisture or oils to cure out. If in doubt as to surface strength a core sample should be taken.
Macadam and Asphalt should be laid up to a 6mm or 10mm close graded wearing course. New Macadam or Asphalt should be sealed with our Resin Bond Acrylic Sealer to seal the surface and prevent the absorption of the resin as it is applied. The same Acrylic mixture can be used to level an indented surface.
Concrete surfaces should be abraded or etched to remove laitence (the dusty material on the surface of new concrete) and our Resin Bond WB Primer should be applied by roller to prime the surface.
The hardener is mixed thoroughly with the resin using a 110v drill and paddle mixer. The resin mixture is then poured onto the surface at a rate determined by the aggregate size. The resin is spread across the surface using a serrated squeegee. As the serrations in the resin start to level, the aggregate is gently scattered over the resin until it is saturated. Apply additional aggregate to areas where the resin bleeds through to the surface.
The following day, the excess aggregate is swept off to reveal a finish which has the appearance and texture of loose aggregate but has the advantage of being durably fixed in place.
