What the 'Mixer' does

This is based on the Derbyshire Specialist Aggregates 7.5kg Mix Design

Be Clean – Be Consistent – Be Safe

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 Mixer is responsible for the following:

1. Place the first Standard Bag of 2-5mm stone and the Standard Bag of 1-3m stone.
2. Add the pre-mixed resin.
3. Add the two remaining bags of 2.5mm stone.
4. Slowly add the bag of sand.

Stages 2 to 4 must be mixed for the same duration every mix. Failure to do this will cause colour variation in the mix. Use a stopwatch when mixing.

This should be no more than 5 minutes once the resin has been added. Once the sand has been added, make sure it has been distributed evenly through the mix.

5. Switch the mixer off and empty the mix into your lined barrow.
6. Ensure all mix is scraped out of the mixer, taking special care to remove it from the blades and from the door of the mixer.
7. The ‘Luter’ then takes the mix to the ‘Troweller’

Important notes

• The Mixer cleans the mixing equipment down and checks that it is in good order.
• It is important to clean the mixer thoroughly each time to avoid build-up of resin – this avoids a lengthy and difficult clean up at the end of the day.
• Regular cleaning avoids contamination and clumping – residue from previous mixes could end up in a new mix. The old mix will have started to cure and will cause problems for the trowelled when they are laying the mix.
• Wipe the mixer round thoroughly with white spirit until all residue from the previous mix has been removed.
• Check the blades are not worn; excessive wear will result in an uneven mix and a longer mixing time.

Tip: Lightly spray the inside of the mixer with WD40 when clean – this will stop the resin sticking so much to the mixer.
