Will Chestnut Spirit Stain be compatability with Oil Varnish

[Tetsuaiga]

Sorry if this has been asked before.

I was thinking of using this but then read it can be thinned with cellulose thinner, making me imagine that's what in it already.

I intend to use an oil varnish - tru oil finish after but I seem to remember reading cellulose or cellulose thinner itself will react with oils and burn through them or something like that.

Perhaps I could make a barrier coat between the finishes with shellac?

I have not used Chestnut stains but if you allow it to dry completely ( several hours ) I can't see that you would have problems, if it does have cellulose thinners in it, the cellulose will evaporate. The only stains I can think of that would give problems would be an oil or naphtha stain.

Thanks. I might give these a try and see what happens.

Spirit Stain doesn't contain cellulose, but it is a suitable dilutant for it in the absence of Spirit Thinners.

As said, once the solvent has evaporated there would be no problem; applying a cellulose product over an oil would be asking for trouble.

Great to know thanks.

Best to stain first then coat with Oil afterwards otherwise the oil will resist the stain, once the stain is dry though the oil will not bother it at all.

I must confirm Terry's assessment on Oil and cellulose products, I made a small pot that I coloured with Chestnut's stain and finished with their acrylic lacquer (cellulose solvent) and even though it had dried thoroughly, when I later applied an oil finish to the interior (I could not properly spray the inside it was too small) the oil penetrated to the outer skin and blistered the lacquer, it took a great deal of work to get the outside back into shape. I won't do that again!
