Got some questions on shellac. I’ve been using it as my preferred finish for years, but I’m still not clear on a couple of things. I normally use the regular Zinser shellac (clear or amber depending on what I want), but recently I bought some of their sealcoat because I planned to put a final coat of poly over it for a table I’m working on (though I ended up buying some Deft brushing lacquer instead, since I hear good things about it).
I’ve seen it said here that Zinser shellac is a 3# cut and that Zinser Sealcoat (dewaxed shellac) is a 2# cut. I’ve also seen it said here that the regular shellac is a 2# cut and that the sealcoat is a 1# cut. So which is it? Certainly the sealcoat is thinner… I poured some into a jar and thinned it 50/50 with DNA as I normally do for the first couple of coats of regular shellac, and boy, was that thin! Took quite a few coats to get close to where I wanted, and even then I wasn’t satisfied, so I put some uncut regular shellac on the legs (I’m going with shellac alone everywhere but the table top).
I know that dewaxed shellac is the appropriate type if it’s going to be topcoated with anything else, but what, if any, is the advantage to waxed shellac? I prefer the look to the dewaxed I used on this project, but I don’t know if that’s due to the wax or due to the very thin mix.
