Gravel Resin - What Should I Use?
Gravel Resins for Resin Bound
When considering laying the Resin Bound system it is critical that the resin used is suitable for the application it is being used for.
There are many different resins available on the market, however it can be broken down into two main types - UV Stable (Aliphatic) and Non-UV Stable (Aromatic).
Please note, we only recommend the use of UV stable resins in application of resin bound.
What are the key differences?
Resin technology is a sophisticated process, this mixed with dried aggregates creates a beautiful and durable system. This is achieved by choosing the correct components to mix.
AROMATIC - NON UV STABLE
Aromatic non-UV stable resins are used predominately due to price, as they are a cheaper alternative to the aliphatic UV stable resins, however the hidden cost of using a non UV stable resin is that the surface can degrade and the original colour of the surface will change and degrade.
Although in theory aromatic resin is a stronger resin this does not mean it is better, in fact the strength of the resin can in some circumstances lead to cracking. The main issue is the instability of the resin colour. The light instability occurs very quickly and this change will create a variable shading and clouding in the surface. Once the sunlight starts effecting the resin, it is not only the colour that becomes affected but the also the long term strength. This can lead to the surface becoming brittle and starting to break up.
Aromatic resins are acceptable for use in resin bonded applications, where the stone is broadcast across the resin and therefore the sunlight does not affect the appearance or strength of the finished surface.
Benefits of UV Stable Aliphatic Resin
UV Stable - The benefits of using a UV stable resin is the protection it gives against the damaging UV in sunlight. It prevents the issues of colour change and break down in the surface and the surface.
Flexibility - This resin also has a degree of flexibility which allows the surface to move without cracking.
Moisture tolerant - This resin can withstand moisture in as little as 4 hours when laid at 20 degrees.
SUDS compliant - both types of resin will create a SUDS compliant surface.
The only choice for a reliable and sustainable surface is an Aliphatic UV stable resin.

What can go wrong with Aromatic non-UV stable resin?
The picture here shows where staining has occurred due to using non-UV stable resin. The resin rich areas have created a "stained" appearance that has manifested following the effect of sunlight on the non UV resin. This has occurred as the hardeners used are a dark brown as opposed to a colourless hardener used in the UV stable resin.
Resin Bonded Aggregates from Derbyshire Aggregates only approve the use of UV Stable Aliphatic resin for use in Resin bound systems.
