I would use exterior paint, however the paint is for Chroma Key-ing (a very specific colour that computers use when doing some video editing) so I definitely need to use this paint, but I need it to survive the elements! Any help really appreciated, thanks )
Thanks for your reply Geoff. I don'm mind with or without shine. Matt would be better but I could cope with it either way. Under normal circumstances I would of course use masonry/outdoor paint however, as I said in my question, because it is special paint, I don't have that option, so need to look at putting some sort of coating on the top of it to protect it.
Hi Boyboy, I'm not sure? I know what you're thinking and I think an exterior varnish should do the trick...I'm just not sure if it would act as a solvent to the emulsion and damage the base colour on application. What do you think? )
