painting steps, rain, etc.

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 mineral spirits?

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?

Did the can say 1 part thinner 9 paint ? If you wait you just have to sand as the film gets hard,

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.
