It actually crossed my mind that you might be an American living in Spain Welcome to these forums, and let us know how your home made sanding sealer is working for you. Richard Coers. Lacquer sanding sealer is lacquer with zinc stearate added for the powdery easy sanding component. It might sound stupid to some of you but, I like using either tung oil, danish oil, or walnut oil on my bowls. I also like to wet sand because I hate dust so i've been using whatever oil I use on that particular piece for my sanding lubricant but this gets really expensive with the tung oil and walnut oil since it takes a good bit to wet sand properly.
I don't want to use water for wet sanding but i'm wondering if I use anything besides the oil I plan on using on the piece it will mess with the finish. Bill Boehme Administrator Staff member. My opinion about lubricating sandpaper with oil when sanding wood is that it just masks sanding scratches and dulls the figure in the wood. The sludge of oil and wood dust and oil packs the pores and helps to mask fine scratches and seems like it also reduces the effectiveness of the sandpaper because of clogging.
It is good that you are concerned about breathing dust because it is a real health hazard. I think that there are a number of effective ways of dealing with wood dust. Wearing a dust mask or respirator is something that you ought to be doing anyway while turning. Using a dust collector or shop vac funnel near the work while sanding also help a lot in capturing dust. A fan at your back also helps. I sand outdoors so that I don't have to contend with a dusty environment in the shop.
Varnish over oil gives a nice finish, but I would allow sufficient time for the oil to cure. For walnut oil this means a month or two. Tung oil is also slow drying and might take several weeks.

For instance, lacquers come in many different formulations and many brands will have a separate sanding sealer that is meant to complement their finish. Dewaxed shellac is often considered to be a universal sanding sealer.
If your favorite finish does not have a complementary sealer, dewaxed shellac is a good choice. This provides good soaking into the grain before full bodied finish coats are applied. Sanding a first coat of oil into the wood and wiping off the excess will seal the wood pores. Sealers are manufactured for varying purposes, such as grain filling, flexibility for the topcoats and, of course, ease of sanding. Used alone, they might provide a quick build and an attractive finish in several coats, but this is seldom a good idea because they do not have the durability that topcoats provide.
Because sealers are meant to be a foundation for the topcoats, it is best to use only one or two coats before top coating, and it is not a good plan to try to sandwich them between layers of topcoats.
