Lol. how on earth do you lose the lid for a paint tin?
I'd suggest a couple of layers of cling film with an elastic band around the top to keep it as air tight as possible?
You could always buy a paint kettle, which is what your painters will have used. They come with plastic lids (like tuppaware i guess). But they probably cost more than your paint is worth, so stick to the cling film
A painter will have to advise on thinning your gloss for you, but a paint kettle....is...err...a paint kettle. It's just tupperware (or metal) for paint. I really can't see there being big differences in quality.
Is there a lot of gloss paint left and is it expensive stuff?
If not, then it may not be worth all the fuss just to save it. Buy new!
jam jar or pickle jar with tightly fitted lid. Wash out the old tin with a drop of your thinners and tip that into the jar.
White spirit is thinners for most oil paint. Some paints are thinned with water. If you can't tell, try a drop on a bit of stick or something.
Hi John. That sounds like the oil-based version so will require white spirit to thin it. Easiest way to tell if it's oil-based is what the tin says to wash brushes in. Wash brushes in white spirit = oil-based paint = white spirit to thin paint / wash brushes in water = water based paint = water to thin paint.
