Anyone know if plain old white barn paint will adhere (and stay
adhered for a few years) to bare concrete without any kind of priming?

I just sealed a couple of my exterior-facing basement walls against
moisture, and the whiteness makes quite a difference to the brightness
levels down there compared to gray concrete - so it got me thinking
about doing some of the internal walls with the barn paint that I
have.

Maybe it'll just all fall off, though, or maybe it'll go chalky and
leave marks on anything that rubs up against it... but OTOH it's not
like it has to cope with sunlight or rain, so it's probably just a
case of how well it'll stick to concrete instead of wood.

Eventually, and once I know I've got all the moisture issues under
control, I'll sheetrock down there and make the space more habitable
- in the meantime it just needs to be functional, but not pretty :-)


Contemporary outside paints no longer go "chalky." Paints were, back in the
day, formulated to undergo controlled shedding of their exterior surface.
When the paint turned "chalky", a bit was washed off with the rain, taking
stains and dirt with it. The result: The painted surface looked better.
