I use clean water to clean the nozzle just spray true it a couple of times, that works fine. If it dries up use a needle to get it back open again.\ said:Ron, it's a complete mystery to me too. I figured that even if the PVA didn't work, then the water I diluted it with would react with the plaster and cause it to set. I also thought the emulsion I first used would have provided an adequate seal for the polystyrene.Anyway, I'll try one more time with neat PVA. If you hear a loud scream tomorrow, you'll know it didn't work!
Richi - I've got a couple of spare spray bottles and I had thought of mixing up some PVA in water to use as a spray adhesive. How do you stop the glue setting in the nozzle after using it?
