Hi, is it possible to spray on a 3-1 pva mix from a 5lt garden spray gun if so, will it need to be cleaned through after use to stop it from glogging up ..... cheers

I suspect you would have to water the PVA down so much to get it thin enough to spray. I am not sure the chemical make up would allow it to be atomised??? I have enough trouble with spraying paint :lol:

I think thats a very long shot!

a 3:1 pva mix would be quite gloopy, garden sprayers are designed for water with a bit of weedkiller.

Easy, we spray block pavior sealer through a sprayer regulary, similar thickness to diluted pva, I also spray wax oil with them.

Just the simple case of unscrew the spray head, remove the brass end, it will either have a very narrow slot or minute hole, just drill it out a big bigger to suit.
Ive also just removed it, then replaced when finished.
We just run soapy water through it, but with pva clean the head with a drop of white spirit.

no but we used to spray egg whites onto newly built stone fireplaces to seal the stone and stop it dusting.
