Nerdy paint question...

    I try to wait at least 48 hours before adding paint to an already painted surface. But when is the best time to sand the previous coat?

    Assuming the paint is dry enough to sand in 24 hours, might there be a benefit to sanding after 24 hours? The paint is softer than it would be at 48 hours, so it'll be easier to scuff up the surface (though you'll need to sand more lightly). And might scuffing the surface expose some of the inside to air? and thus speed up the drying/curing process?

    Or is it better to wait 48 hours before sanding.

    Howie,
    You're thinking too much again. If the paint is dry, you sand. If it's not, you don't. Go have a cold one, relax. Repeat if necessary. You'll feel better. Sand tomorrow.

    See you at Assembly.

    If sanding makes dust, I am ready to paint. If the paper gums, I let it dry longer. Same for varnish.

    At least, that's how I do it.

    If in doubt, Howie, read the instructions on the can.

    Dries faster if you pull up a chair and watch it, or... is that slower.
