Re: Taking off old finish on old cabinets.
I haven't heard of "liquid sand" but I have heard of deglosser. I'm guessing they're the same thing. I only mention this to help you in your quest by giving you extra terms to ask for.
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.
