What the 'Luter' does
When laying a resin driveway, or any other surface, your installation team should consist of three people. These are:
- The Mixer
- The Luter
- The Troweller
Each has a series of key roles and responsibilities to ensure your work is completed safely, effectively and without wasting any time or money.
The Luter has three main responsibilities:
- Emptying the completed mix from the mixer into the wheelbarrow.
- Tipping manageable quantities of the material between the batons of your site, carefully judging the correct amounts to apply.
- Evenly spreading the mix between the batons with a lute, ensuring consistent and smooth coverage.
The Luter must inspect the surface that has been previously trowelled out and check for any trowel marks or inconsistencies in the surface. This must be done from every possible angle. Any anomalies can be easily rectified at this stage before the mix has cured.
Achieving an Optimum Strength Surface
In order to ensure your surface is strong, a resin bound installation should consist of the following:
- UV stable resin/hardener: 2.14kg per square metre (approx. 3.5 square metre coverage).
- A blend of 25% 1-3mm stone and 75% 2-5mm stone.
- 1.78kg fine kiln dried sand per square metre (C52 sand).
- Finely crushed glass or C52 sand to apply slip resistance to the surface.
- A temperature of 15 degrees centigrade for the duration of the installation. A catalyse is required for temperatures below 15 degrees centigrade.
- No rainfall.
- Air temperature above 5 degrees centigrade and humidity below 80%.
- Surface temperate should be 3 degrees centigrade higher than dew point temperature. Use a hydrometer to check this.
- Ensure all preparation work has been completed.
