Re: kids drew on every wall with crayons
An oil-based sealing primer is going to be a must. Acrylic latex primers will not adhere well to the waxy residue the crayons leave behind.
EDIT: I've learned that a shellac-based primers is an even better options. I haven't tried it myself. Someone said latex primers are good, but I'm skeptical. I guess you could try it and see. Whatever primer you try, paint it on, let it cure at least a week, then try to wash it off. If it comes off easily, forget it. If it is hard to wash off or doesn't come off at all, you may have good results.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
