The Resin Bonded Aggregate system uses a coloured resin applied to Concrete, Tarmac, Wood or Metal to hold an aggregate. In appearance it is like a loose aggregate but without the problems of shifting stone. Its very durable. As well as paths and drives this system can provide a friction finish for disabled ramps. The following link is to a range of finishes available in this system.
Preparation
Surface must be clean and dry and of strong enough construction 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.
Concrete surfaces should be abraded or etched to remove laitence (the dusty material on the surface of new concrete) Resin Bond PU Primer applied at 4sqm per kg by roller.
New Macadam or Asphalt should be sealed with Resin Bond Acrylic Mixture to seal the interstices between the stone to stop the resin soaking away as it applied.
Application
The resin is thoroughly mixed with its hardener using a drill and paddle mixer (110V). The resin is poured across the surface at a rate determined by the aggregate size.
The Resin is spread using a serrated squeegee.
As the serrations fall from the resin the aggregate is gently scattered in until the resin saturated, if any resin is seen to bleed through more aggregate is scattered on.
The following day excess aggregate is swept off to reveal a finish which has the appearance of loose aggregate but is durably stuck in place.
