Lots of folk ask us the difference between Resin Bound and Resin Bonded Coverings
In resin bound surfacing the aggregate is mixed with the resin in a specially designed mixer. The material is then trowelled down to a smooth finish similar to a screed (with no loose stones). Depths are specified depending on use, normally 12mm, 16mm, 18mm or 24mm.
Resin bonded surfacing is a scatter system which provides texture and the appearance of loose gravel.
A layer of resin applied to a suitable surface and covered with loose aggregate. Once cured the remaining loose stones are removed. Thickness is governed by aggregate size. i.e. 1-3mm aggregate will have a nominal depth of 4mm.
There are benefits to both, Resin Bonded would give more grip on foot and Resin Bonded perhaps looks more finished and smooth.
