Can anyone provide tips on fixing tiny cracks in a cultured marble 80s vanity sink surface, known as crazing, before painting it?

Hey there! I could really use some advice on how to repair my bathroom sink. It’s an 80’s vanity made of cultured marble, and I think it has what they call “crazing” – you know, those small cracks that don’t go all the way through. I’ve heard about bleaching it, but I’m hoping to fill in or smooth out the cracks since I’m thinking about painting the vanity top. Any help would be appreciated! Thanks!
That doesn’t seem to be marble; it resembles cast iron with a cracked finish.
Mentioned that cultured marble and fiberglass tend to exhibit this issue.
She’s no longer available – consider purchasing a new one from Wayfair, check out the clearance section for good deals. If you or a friend have an EIN, signing up for Business can get you a significant discount. It’s unlikely that this can be fixed. Opting for a reglaze or a rustoleum product is only a temporary solution. It’s more practical to invest your money and time in a replacement, even if it’s from IKEA, as it will last longer.
I see Marshall’s point about replacing the item, but if you really want to patch it up, you might want to clean it thoroughly first to ensure proper adhesion. Applying bondo or a thick 2 part epoxy could also help.
It’d be much easier to simply replace it.
The patches can be costly and will give off a patched look. Accept it as is or search for a pre-owned replacement on Marketplace.
Instead of refinishing, consider checking alibaba for individual sellers. Their prices beat everyone else’s by a long shot (worth the search).
