repairing lacquer finish.

[_lotusbleu]

I've had someone drop off a table that has had the finish damaged by solvents, leaving two white marks on the top.

what's the best way to go about repairing the finish?
I got some polyvine wood lacquer - will it just be a case of touching up the damaged spots with it?



thanks for any advice!

Do you know what the solvent spilled was? It wouldn't be nail polish remover would it?

If so you could try spraying them lightly with cellulose thinners and then letting it evaporate, with a bit of luck when the existing lacquer rehardens the white marks will have gone. This can be repeated if necessary if the first go improved things but didn't get it all.

And without that "bit of luck" it'll go all wrinkly and scabby, or you'll remove the two milky patches but be left with two matt patches that won't be remedied with a dab of Polyvine.

Another wizard wheeze you'll find on the internet is using a hot iron and a towel, good plan...until you start lifting the veneer.

Konig have some half decent solutions for lacquer repairs without a spray shop, they're not cheap but if you email them they may give you some advice that they'll stand behind. Unlike the advice you'll get on-line, when internet advice goes Pete Tong you're on your own!

Solvent treatment is an established method for fixing certain defects in solvent-borne finishes, i.e. shellac and lacquer, as I'm sure custard knows. And this is a recommended course of action (one of a number) in at least three finishing books for pale marks caused by water.

Google finish reamalgamation for more.

I have failed to get this right more times than I would want to count One of my hobbies (early money maker) for 30 odd years has been making and repairing acoustic and electric guitars. Wide range of finishes. Unless you know what the original finish was you are left with tests in inconspicuous areas. You can waste a lot of time patching up compared with a refinish (not on something valuable).

I've done plenty of "pullovers", on both shellac and lacquer, which is how I know real life isn't like a Bob Flexner book!
