Cleaning spray gun between coats ?

flanajb · 15 May 2011

Hi,

I am about to start spray priming a piece of furniture with Morrell's water based primer and wondered how other sprayers deal with cleaning the gun between coats ?

I believe that you need to leave 1 hour between coats and as the piece is not that large I am not sure it will take one hour, so I was wondering what I can do to avoid having to clean the gun between the coats ?

Any tips welcomed.

Thanks

Justin

well i've never done this, so will be interesting to see how far people go to get their finish, spraying as we speak 28 table tops, ac cat, not cleaned my gun once yet today, i left it for an hour at lunch, still spraying perfectly fine.

Yes for short periods of time it is fine to leave the paint in the gun for an hour or so between coats. If the next coat was to be in say three or four hours I would take it out of the pot and spray some thinner through until I was ready for the next session. Of course if you are using PU I would take it out of the pot in between as this dries in around three hours. HTH. :wink:

Certainly does help and thanks. Just one quick one, what is PU ?

I am using morrell's water based primer. I suppose I better get cracking rather than sitting on the computer drinking coffee!

Thanks

sorry should have mentioned that i clean my gun out after i have finished using it, its very rare that i need to leave it for more than 1 hour or so.

Does the surface change when it's ready for a 2nd coat? The paint I bought (some industrial Akzo-Noble acrylic paint, meant for windows and such other outdoor things) changes from very glossy to satin look - the paint dealer said it's ready for 2nd paint then. That actually does not take that fast, so I've been able to start from the 1st pieces and once I've done the whole round - the 1st ones are dry already - I can just keep spraying. This of course on the number of pieces you have, I had something like 35 today.
