I’m trying to get a little info about the process and supplies needed for wet sanding smaller projects. I believe I’ve heard some use tung oil with wet sand paper? Can anyone back me up on that?? If not how do you smart fellers do it. Thanks for the replies..

If you are wet sanding a finished project, then use water, or turpentine with sandpaper. If you are doing it as a first coat for the finish, then use boiled linseed oil or tung oil cut 50/50 with mineral spirits, then after you sand the surface, wipe it off lightly against the grain. The slurry will act like a grain filler.

Ryno, you did not say what finish you are using, for poly I will wet sand with water inbetween coats. For shellac I wll use mineral oil to wet sand inbetween coats.

Hey Ryno
What ever finish your using let it dry as long as possible, then use water with just a few drops of dish soap and clean your surface frequently and use 400 grit or finer.

Murphy Oil Soap and water. Just a few drops as a surfactant. Not a detergent, just a lube.
There used to be a product called Flaxsoap. A vegetable-based product we used in the piano refinishing shop as a sanding lube.

I was taught when a boy doing up car bodies to use soap and water worked a treat prior to spraying My uncle Tommy taught me this way and it worked fine.Alistair

If I’m using the tung oil and sandpaper as the first step, do I really have to use wet/dry sandpaper. Is this an obvious question?? And I was thinking about using 60 or 100 grit for this step. Does this sound reasonable?? Thanks for all the good info..

If you are wet sanding you should be using 220 grit wet dry sandpaper, not 60 or 100. That’s way too coarse.

ryno, once you get through the grits 60 80 110 220…then you wetsand with the tungoil or blo to help fill the pores…but you have to dry sand it up so the surface is smooth first.

Generally I use mineral spirits or water with wet/dry paper in the 400, 600, 1000 grit. After that I use miineral spirits with pumice and rottenstone. The rottenstone can put a gloss finish to flat varnish.
