The main differences are thickness that the systems are applied, application method, appearance and aggregates used.
Thickness - A resin bound system is applied between 12-25mm thick. A resin bonded system is applied as a thin veneer of resin and then aggregate on top approximately 5mm thick depending on aggregate size.
Application- Resin Bound is trowel applied. Resin Bonded systems is where the resin is applied and then the aggregate is scattered on top of the wet resin.
Appearance - Resin Bound Systems are fairly flat and even. Resin Bonded Systems are rough in texture taking on the texture and appearance of the aggregate as this sits on top of the resin.
Aggregates- Resin Bound systems use a combination of 2 or more grades of aggregates that are different sizes (2-5mm and 1-3mm). Resin Bonded systems normally use one size grade of aggregate such as a 1-3mm.
Polyurethanes are Quicker curing, especially at lower temperatures, are less affected by extremes of temperature and offer greater flexibility. They are also less affected by age embrittlement and less prone to debonding. Epoxies are generally brittle in nature.
Bound Resin is permeable as it has many voids across its entire surface area, making it more effective than other SUDS compliant systems. The water is able to soak through the surface, filtering through the voids and drain away.
The sub base must also be SUDS compliant therefore we have a specific SUDS base build up specification detailing the requirements.
We recommend that you use a forced action mixer for best results.
The minimum temperature that resin can be applied at is 5°C. If Resin is to be applied on a hot day it is best laid early morning or late afternoon as the resin will become thin in excess heat and could potentially drain away
On good surfaces a primer is not required, but on a friable or dusty surface then we do recommend that the surface is brushed and primer is applied. Primer C is an effective primer.
In simple terms the two resin components are first mixed together using a drill and paddle. The resultant resin is then poured into a forced action mixer that has be pre-charged with the selected aggregate. The resin and aggregate are then mixed until all of the aggregate has been fully coated. This mix is then transported to the application area and roughly distributed. Finally it is compacted and finished using a trowel.
It really depends on the end use of the installation but we recommend:
15mm - if the installation is to be used by pedestrians only or the sub base is strong and sound and can withstand the expected loads.
15-18mm - for a standard driveway - with light to medium traffic
25mm - for an installation area that is expected to withstand heavy vehicles
If you are unsure as to how thick you should install the system please contact us.
Typically 100kg is required for one 7kg pack of Trade Buff Resin or 6.5kg pack of UVR Resin. Aggregate is normally sold in 25kg bags, therefore one pack requires 4 bags of aggregate.
Yes – Resin Drives have two types of resin the Trade Buff and UVR Resin. UVR is an aliphatic polyurethane system which is highly light stable and is exceptionally resistant to discolouration after exposure to light. It is best suited for use with light coloured aggregates or other aggregates where colour stability is a key requirement.
