First off, I apologize for the pictures. It was devilishly hard to get a picture of the damaged areas and I don’t think it turned out so well.
I just got a coffee table to my girlfriend. I finished the table with Deft gloss brushing lacquer. I put on several coats. After the last coat I let it sit for a couple of weeks. Then I rubbed the finish out using sandpaper and mineral spirits. I let it set another couple of weeks, possibly more.
Everything went fine until we got pizza. We put some pizza boxes on the table. When we lifted the boxes there was what looks like damage to the lacquer. There are patchy areas of dullness anywhere the pizza boxes were. It’s as if someone spilled some lacquer thinner on there or it was sanded with 220 grit sandpaper.
Water spots have not been a problem. The finish appears to be water resistant. I even tested it with orange juice to see if acids would eat into it. Nope.
I thought at first it might be the coat of wax I had put on there melting. But I’ve rubbed and rubbed at these spots, including water and spray cleaner. Made no difference.
It would appear the lacquer has been damaged. But I don’t see how. I gave it plenty of time to cure before rubbing and even more afterwards. I have finished other stuff with this lacquer and the other stuff isn’t giving me a problem. In fact, there’s another table I made with Deft brushing lacquer. It went through the same regimen. I put the pizza boxes on it for destructive testing. It’s perfectly fine.
Does anyone have an idea as to what’s going on here? I can always brush on another coat of lacquer but I want to know if this will haooen again.
It’s supposed to be a workaday coffee table. It should be something that doesn’t have to be handled delicately. It should able to take use and some abuse. I realize nitro lacquer isn’t as tough as polyurethane but it’s pretty durable. And the majority of factory made furniture is finished with lacquer.
I took some digital pictures. The damage can only be seen in a raking light and so it’s difficult to make the damage out. I tried to point it out but it’s still hard to see. But to the naked eye it’s extremely obvious. I can even feel the roughness.
My assumption at this point is that the heat damaged it. What happens when she puts a hot coffee cup on her coffee table?
Insight would be appreciated. Thank you.
