cheers all,

i build small boxes and my finish of choice is lacquer. however i have to use so many coats to get a good finish because it soaks into the wood. is there any finish i could use under the lacquer to seal the wood resulting in fewer coats of lacquer.

Like AlaskaGuy suggests, the amount of solids varies in different lacquer products. There are some high solid lacquers sold in aerosol cans too.

The “Brushing Lacquer” is a lot thicker, in my experience, and covers better.

Perhaps a blotch control method would work. Read here. Only if you dont color the wood. The glue size or thinned wb finish will raise the grain and require a light sanding. Properly wiped off either will not interfere with the lacquer.

I also make many small boxes. Mine are made of cedar, which is a soft wood and absorbs finish a lot. I gave up on using lacquer and now I apply one coat of shellac, I wipe it on. I then sand it smooth with my orbital sander using 180 grit. I then apply two coats of wipe on poly sanding between coats only if necessary. Shellac will also work under lacquer.

Is that the de-waxed sanding sealer shellac or just regular shellac? I’ve always been afraid of putting anything over the regular shellac since I figure the wax in it would prevent a good bond.

You are correct, the wax will cause problems for some finishes. But de-waxed shellac is fine. It’s sold by Zinsser as “SealCoat” in a pre-mixed variety.

Sealing with regular shellac (with wax) will be okay if you are following with oil-based. The SealCoat, which as William Shelley pointed out, is de-waxed, would be good under either oil- or water-based. I’ve used the SealCoat several times. It’s a 2 lb. cut and it’s a little sticky, so I’ve thinned it 50/50 with denatured alcohol and wiped on several coats. It’ll raise the grain a bit, so may want to give a light sanding before continuing on with your lacquer.
