PVA means poly-vinyl-acetate to me. That nasty old white glue that
everyone sells for too much money for the performance you get out of
it.

When it was first introduced, I remember it was referred to as "rubber
based" paint as opposed to "oil based paint". Now it is called "acrylic
latex paint" versus "alkyd oil paint". Names tend to vary in different
regions of the world. Latex is thinned and washed up with water, oil paint
is thinned and washed up with solvent.

Let the paint settle out, decant the thinner. It works as well as fresh
for cleaning the brush. With care, you won't have any thinner to dump;
it'll all evaporate by the time you need a new can.

Oil-based color is richer, deeper than latex. WAY richer and deeper. You'd
expect it from pigmented varnish compared to pigmented rubber.

It is possible that, if you in South Africa follow the British
conventions, the water based latex paint would be called emulsion.

Thanks for that. That would equate to what we call PVA. A water based
interior and exterior paint.

Thanks to all the others who replied

Anyway now I know. <G>

G'day Phil,

we call latex "acrylic" which is described as"

"Acrylic paints are a synthetic media made by suspending pigment in
synthetic polymer emulsified by water. They are essentially plastic paints
that are water-soluble and have good adhesive qualities. They are very
stable. They resist oxidization and chemical decomposition, and will not
yellow over time."

SA and OZ are somewhat similar so I expect you use the same name.

cheers,

Greg

Could you be more specific as to why? I could see someone arguing as to the
performance of an oil based paint, but how could the cleanup be
easier/better for oil-based paint? Even if you dont mind the smell of paint
thinner, there is still the fact that you cant pour the excess paint or
dirty thinner down the drain without breaking laws in just about every
state. (Not to mention polluting).

Why do you prefer the oil-based cleanup?

Latex paint is a water based rather than an oil based product.

Believe it or not, it was introduced right after WWII as an interior flat
finish product for houses.

Those early efforts were to say the least, less than spectacular.

Latex paints have come a long way since then.

Today they are the primary paint for the architectural market. (Houses,
industrial buildings, etc)

Latex is replacing oil based paint almost everywhere in the US, because of
environmental issues.

Latex forms a skins and bonds to the surface as opposed to oil based which
penetrates the surface when forming a bond.

I'm not a paint chemist so some of the details might not be totally up to
snuff, but the general idea is accurate.

That is why I use 2 Coffee cans of thinner, 1 for the initial clean up and
the second for the final cleaning. The second one gets dumped into the
first on the next day and filled fresh again.

Sticks better too IMHO. Also IMHO you can scrub it harder after it has
cured.

Yeah I do that too, really helps the paint flow off the brush. I find that
Wooster brushes have good seals and don't let the water or thinner run down
the brush handle if you get too much on the brush. Oddly, Purdy lets lots
of thinner or water run down the handle. I suspect they have no seal.

Gudday Phil, if I were to reply every time we kicked your *rse in sport
you'd be swamped!

Lol,

cheers mate,

white glue, yup.

also the gazillion other members of that chemical family tree, ranging
from some really expensive archival grade adhesives to yellow glue to,
yes, latex paint

What people have failed to mention to you, is that latex paint cleans up
with water. That's as long as the paint hasn't completely dried. That means
that your brushes, your hands, your paint tray all clean up with a little
rubbing by running them under the water tap. That's its biggest benefit as
far as I'm concerned.

I've found that preconditioning the brush prior to dipping into the
finish is a BIG step in cleaning as well as preventing the bristles
from stiffening by stopping the finish from drying near the ferrule.
I was raised used oil based stuff as that is what was available and
early WB stuff was a giant step backwards. Not so today! WB stuff
works now and is what I've switched to. Still have MS on the shelf
for infrequent needs.

Personally I will prefer oil based clean up as opposed to latex clean up.

In the beginning, I hated the thought of dealing with oil based paints until
I painted a couple of houses.
To address the waste, I live in Houston TX, we have centers to deposit the
waste thinner at no charge. With that in mind, having helped a friend paint
house interiors for the last 7 years, I have found that cleaning a brush
regularly during the day, "at least at lunch time and the end of the day",
dropping the brush in 2 separate cans of thinner and then rinsing the brush
in soap and water takes about 3 minutes for a totally clean brush. We can
make a gallon of thinner last a week when painting every day. When using
brushes to cut in the walls with latex paint, the clean up normally takes 3
time longer with soap and water. The thinner on oil based paints takes the
work out of clean up. Additionally, when actually painting and you have the
inevitable spatter or drip on the floor, oil based wipes up immediately with
a thinner soaked rag as opposed to latex smearing around with a wet rag.
I'll take a small oil based cleanup on carpet any day over the same clean up
with latex paint.
