Polka Dot Paint   (+5, -1)  [vote for, against]
Oil and Water don't mix

A small amount of oil based paint in a water based. Stir vigorously. The oil paint will form into droplets. Pour into a shallow pan. Use a roller.

Are you able to roll out paint with one pass?

I've seen it done, doesn't give you a lot of paint. Perhaps cleaning the rollers with a little water would take the dots away so you would be ready for another pass.

Oh dear I see spots. Reminds me of that damn dog next door.

It generally requires multiple passes over the same area, usually overlapped and/or done from slightly different angles, to apply the paint with an acceptable thickness and finish quality. The repeated passes would cover the dots.

Why only one pass? Have layers of dots, nice dimensional effect.

You won't though, you'll just end up with a muddled mess. For polka-dots to really work they need to be relatively well defined.

What if you were to mix tiny water soluble beads filled with your oil color/s to water based paint just before you paint? If you rolled it out quickly before the capsules broke, I think the oil will repel the water paint in little circles.
Best part is that you wouldn't know what the paint job would look like until after they had all finished popping.

Very cool. And before UB reminds you, alot is a lot, not alot.

Pa've, we're not talking zolotone, here.

They'd be as small as you mix them. From what I'm seeing you can paint them with a paint brush with minor skill. As for the one coat thing, why not paint an undercoat first then put the polka dot paint on top.

2 Fries, I was considering that because its similar to what is done with glazes.

This idea is based upon my friend who put me up to this, saying "Ok, you wanna impress me? Why don't you figure out how to do polka dot paint." So there, the paint is polka dot, it's just that painting with it that will take a bit more skill but it is doable, much like the multi-color swirl patterns in the bindings of old books.

This reminds me of my apprenticeship - striped paint. No, they didn't catch me out.

Hammerite has a similar effect?
