Resin bound patios, driveways, paths and paths are long-lasting and easy to maintain.
Two main types are used for driveways: UV stable polyurethane, and non-UV stabilised polyurethane. UV stable resin is more refined. It is therefore a better quality resin. Therefore, it is the most costly of both.
What is the real difference between these two? It is very simple. UV stable or aliphatic polyurethanes (or aliphatic for scientists out there) retain their clear colour and aren’t affected by UV radiation. Non UV Polyurethanes (aromatic for scientists) change to a darker brown colour if exposed to UV. UV is the best option if you want your resin-bound surface to remain the same colour. UV is essential if you use a light or colored aggregate blend. The finished product will not be the same as the one you chose.
Non-UV can be fine if the aggregate is yellow/brown. However there is a possibility of colour variations due to shading. ).
Non-UV stability systems can become fragile over time from UV exposure according to some reports. However the industry started as entirely Non-UV, and has since been strong and long-lasting. Non-UV resins are often stronger than UV stabilised resins. Use materials with a proven track record.
