I'm in Pennsylvania and need to paint my porch steps. The paint store
told me I don't need a separate primer, that I should do an undercoat of
1 part mineral spirits and 9 parts paint (oil-based porch paint), then
put on a top coat of full-strength paint. The instructions on the can
say I need to wait 24 between coats. The weather has been so wacky--we
never get two solid days of sun lately. Do I need to wait a whole 24
hours after the primer coat, since it'll be thinner because of the
The 24 hours is the drying time, in optimum conditions. You might have to
wait several days for it to dry and then a couple more to put the new coat
on. Hurrying it will only result in doing it again sooner than later.
Okay, thanks. In other words, I will need, at minimum, two consecutive
dry days, which doesn't look likely, according to the weather forecast.
Is it bad to do the undercoat and then the top coat a few days later
when the rain lets up again?
The can says to use a primer; the paint store personnel said I didn't
need to buy a separate can of primer--that I could mix 1 part mineral
spirits to 9 parts paint and use that as a primer coat. Is it necessary
to add sand to the final coat to prevent slipping on the steps?
If you dont want to slip add a no slip additive - sand.
Its necessary to use sandpaper [sand the paint by hand ] if you wait for
the recoat as the can says.
Porch and floor paint [ which I hope you have ] dont usualy recommend
a different product as primer. Just thinning as you are doing.
