Finishing: Wet Sanding With Penetrating Oils

Way way back in college I worked for an antique business in their
restoration shop before I knew what restoration really was. At the
time I was going to be a rock star and had to support myself. I found the job
at this shop listed on the student center bulletin board. Having taken
woodworking in the eighth grade I thought this would be a good fit since I still
have my first ever project hanging over my desk. Here are some tips on a very cool technique I learned at this restoration shop that actually accomplishes
several things at the same time:
-
This type of wet sanding is not for very course grained woods like oak or ash.
-
Tighter grained woods like walnut, mahogany, crotch cut and burls do very well.
-
There are many brands of penetrating oils to work with, I like Minwax Puritan Pine
or Minwax Natural.
-
First, wet the (unfinished) area to be sanded with oil liberally to keep it completely wet
at all times. (1-2 sq.ft.)
-
Using a sanding block with 1200 wet/dry paper, sand in a circular motion with moderate
pressure. Sand the area thoroughly keeping the surface wet at all times.
-
Wipe off the oil and take a look at the piece in raking light. If you see the grain
pours/pattern then repeat this again until there is no grain and the surface is completely
smooth.
-
Wipe down the surface again and check the results. Repeat as necessary until the grain is
completely smooth and the surface is reflective.
-
Once dried for several days, apply a topcoat of your choice.
-
This technique accomplishes several steps at once. Sanding the surface very smooth,
applying a sealer coat, making the grain come alive and lastly, forcing the oil/sanding
dust mixture into the pores acting as a pore filler all at once.
-
As always, be sure to practice on scrap and safety first!! Place all oily rags in water!!!
