It is generally accepted that the two main methods of application for resin bounded aggregate finish. These are Resin Bound and Resin Bonded
Resin Bonded Aggregates
This type of application refers to process of scattering loose dried aggregates onto a coating of resin after the resin has been applied to the surface. It is often referred to as a scattercoat, broadcast or coat system. This method involves applying the resin over a suitable base using a squeegee, and then 'scattering' the chosen gravel or aggregate over the tacky resin before it sets. Some systems use pre-coated aggregates, while others rely on applying a resin over the scattered stone to seal the system.
Resin Bound Aggregates
Often referred to as hand trowelled this system sees the aggregate blended within the resin prior to application and is trowelled to a smooth level finish. Design elements such as logos or numbers can be incorporated into the finished area by using contrasting stone colours to create the desired finish.
This method relies on the aggregate and the resin being agitated together in mixer, and then spread over the prepared base with hand floats, screeding bars and trowels. This type of application generally ensures an adequate thickness is applied to the entire area and is a fairly common method of application.
The above systems ensure that the resin sets relatively quickly in most cases within 60 minutes. This means that the resin and aggregate need to be applied correctly with smoothing out and levelling carried out prior to the resin setting and becoming too stiff to manipulate.
