Our workshop powder coats in many colours - how can we reuse powder spray?

Reusing powder overspray can cause a slight problem for those who paint with several colours. To prevent cross-colour contamination, the entire powder booth, reclaim recovery system, and powder spray gun must be cleaned of the old colour before the new colour is used. This can take a lot of time, depending on the number of guns used, as well as both the spray booth and recovery system size. The decision not to clean between colour changes, known as “Spray to Waste,” is strictly an economical choice. Obviously, if you choose to clean, the value of the powder saved must be more than the cost of labour and lost production time There are two clean-ups in a single colour change: the clean-up from the original colour to the new colour, and the clean-up returning back to the original colour.
