Removing a laquer finish

I've just had some oak doors made which have had a clear semi-matt lacquer applied and I really don't like it. It feels as though it takes away any life from the wood giving it an almost 'fake' feel that could be mistaken for laminate. It's not laminate, but do you know what I mean?

I've a lovely oak box sash window upstairs that's just the opposite - it's dead matt and I think either untreated, or maybe oiled somehow, but that's all.

Would it be possible to remove the lacquer from the new doors? And if so how? And would it be advisable to oil them afterwards, or just to leave them to slowly develop the natural look I'm after?

Thanks

WELCOME TO THE FORUM

You may not have to remove the lacquer. You might try rubbing with a smooth bronze wool, or a synthetic "wool", or a synthetic microfiber pad. This may dull it down enough to be acceptable.

If not, a chemical stripper would do the job, or using lacquer thinner which would be a bit more labor intensive.

Nitrocellulose lacquer will come off with lacquer thinner. Pre cat lacquer or stronger will need a stripper.

Measure Twice Cut Once -- It's a lot easier to cut more off then it is to cut MORON.
Finishing is 3 parts chemistry and 1 part VooDoo http://lrgwood.com

I hope you don't mind if I offer a suggestion. Leo isn't around at the moment. Can't tell what part of the world you reside as you have listed no location. So, I'll give a general answer as to products.

The finish you want to remove is basically a water based polyurethane. A chemical stripper should be used. There are water based strippers, like Citristrip, and there are MC (methylene chloride) based strippers. The waterbased strippers are easier to use and some can be used indoors. The MC based strippers work faster and are highly toxic.

For cleaning of residue after stripping, you could use lacquer thinner.

I don't know what that finish that you are using is, and neather does Google. So like CM said you can use a stripper.

Leo, I'm surprised you didn't know that was WB poly. Google doesn't know because Google doesn't do finishing.

I knew it was WB, but I never heard of it and they have all kinds of weird names for things these days. I pretty much use only ML Campbell products. And most of what I hear about other standard products. Target, Gemini, ICA, SW, MLC and a few others that are industry standards.

Thanks for your help both of you, much appreciated.

I'm in Brighton, UK by-the-way.

I did call the company who make the lacquer/varnish and the technical advisor suggested that I sand it off as there's only two coats of it on there, and he feared that with oak there was a chance of staining or discolouration if I used a stripper.

Do you think that sounds like a viable option? There aren't any complicated mouldings, so it shouldn't be too tricky.

That's too much sanding for me. Sanding doesn't get what's in the pores. I would use a stripper. I don't agree with the staining from the stripper.
