BoundWorx® Accelerator is our Resin Bound catalyst. On cooler winter days, it is wise to add a little more catalyst to speed cure times. On a cool day the mixture will remain workable for up to three hours without extra catalyst being added.

Our BoundWorx® Resin Bound finish should always be laid in dry conditions onto a dry clean surface above 5°C otherwise the cure will be very slow.

To avoid blooming or foaming, do not lay if atmospheric moisture is above 85%. If close to this, ensure some extra catalyst is used.

For general guidance we suggest the following inclusion rate on a normal project where you are laying at up to two pulls of material (you lay a second mix before you get back to your wet edge).

Suggested Catalyst Addition Rates

At 5-9°C use 1-2ml approx. of catalyst per mix/unit.

At 10-12°C use 0.5-1ml approx. of catalyst per mix/unit.

We suggest that if you use the lower end of the scale to start with and check that you have plenty of working time, towards the end of the day perhaps increase as it approaches the cold of evening.

Material will be hard (but may still be tacky) in 4-7 hours using these rates.

Of course, we are here to help should you need any further technical advice.
