Hi British gypsum. Can you tell me if its possible to re***d the set on your spray finish. It would be beneficial to spray plaster on in one go in the morning, clean the machine once and spend the rest of the day finishing the set. It makes more sense than spraying small amounts as you have multi finish for this.
Hi PFTWales, thanks for the question, the simple answer to this would be yes - however, there are some consideratrions to bear in mind. The applied thickness is only approx 2mm, so the longer the setting time is, the more risks of unintended consequences creep in. These include background suction affecting it (particularly a problem if the effect isn't consistent across the wall/ceiling), or drying out by evaporation too much/too soon in summer (in extreme cases this would cause "fire-cracking", "dry-out", etc and maybe adhesion failure).
An alternative way to look at the problem behind the question is this: depending on the building layout and size, it is often possible to spray-apply small amounts frequently, in a semi-continuous way. This keeps "resetting the clock" regarding when the machine needs cleaning out thoroughly. It potentially takes some getting used to for people who have perfected the usual hand-applied, batch-based process (it feels like a slow start to the day), but it can be very productive and might be worth a try?
Let me know how you get on
