Topic tags/keywords: nitrocellulose lacor repair

I have done a little research but need some guidance on this. My step-son tried to clean his new table top and damaged the finish (about a 6 inch circular spot) and then to make matter worse he scratched another section (8 inch scratch (in the finish only, not the wood).

The finish looks like a mat or satin finish on dark wood. Can you recommend some reading and/or steps to how we can fix it? Should we even attempt to fix this or take it to a pro? I have some skill with brush/rub on rinishes but am not skilled at fixing any finishes other than strip and restart.

Merry Christmas to you all :)

Lacquer is very forgiving because it burns into the old coat. If the ding is not into the wood, just brush on some lacquer – get brushing lacquer if you can. Apply several coats so you get good buildup. Then take a flat sanding block and 800 to 1,000 grit wet or dry sandpaper. Use a little water and sand the bump down to flush with the rest of the finish. Then get some white polishing compound from the auto parts store and use a small damp rag to rub it out. Finish with auto glaze for a better shine. Then wax. You’ll never be able to see the repair.

Lacquer dries very quickly but I like to do the above over several days to a week, just to let the lacquer harden. If you do it too fast, you’ll get a flat surface but a few days later the lacquer will finish drying and you’ll have an indent where your ding was.

I have been looking at sprayers for a while but retired this year so I am being careful with my spending (unlike our Gov :)

I have my eye on this:
But I am not sure Santa has decided on the sprayer I need yet.

Just be aware of “fish eye”, the dreaded and evil result of applying lacquer to wood surfaces that have been exposed to furniture polishes (like pledge) that contain silicone.
