    Hi Betty,
    I always use wall putty or joint compound to fill cracks before painting. Paint most likely won't fill the cracks. I just smear it on with a putty knife, smooth it down and let it dry. Once it's dry, I sand it and then sponge it lightly so that it's smooth. Then I paint some primer on it, let it dry and it's ready to go. I hope that helps. Wishing you the best.

    Hi! You definitely want to fill the cracks. The paint will coat the cracks but It won’t level them out.
    I hope that helps

    Use spackling paste, available at hardware stores and home centers. Linda gave good advice re: application technique. Sand lightly, to avoid removing too much compond. Wipe a tack cloth over surface to remove the sanding dust, then prime and paint.
