Hi Peter – I posted this message on the finishing knot also – but I wasn’t sure if you answered questions on that forum.
Help! I am finishing a table that my husband just made with sapele veneers. I wanted a ‘glass like’ finish, so I used the pumice and linseed oil technique as described in Jeff Jewitt’s article regarding wood fillers. I followed the directions, but noticed tView Imagehat after the linseed oil dried, I had a light gray film left on the surface. I thought maybe I could lightly sand it off with 600 grit carbide sandpaper – which didn’t work. I then tried using a little paint thinner to wipe it off – which looked great while wet, but dried with the same gray film – this time with wipe marks. I’m not sure where to go from here – any suggestions? I’m desperate! Thanks! |

A pumice and oil fill can sometimes be tricky. One thing I would add to the pumice is a pinch of dry pigment that is close to the color my finished wood will be.
You can find dry pigments from Homestead or Woodworkers Supply. At WWS they are sold as Fresco powders. I don't know what your wood color is but consider burnt umber pigment for this step. You won't need much pigment to make a difference. About a 41 ratio will work.(4 parts pumice,1 part color)
The streaks on the surface are probably the oil reacting to the solvent. A little elbow grease and a grey scotch pad might take care of that.
Did you seal (washcoat) the surface of the wood prior to filling?
You said when you wet it the haze went away. The finish you use should have the same effect. (Theoretically)
My main concern would be that the pores are filled enough. If they are still shallow, you may consider refilling them the same way or use one of the fillers on the market that are pre colored. ( I'm talking oil based here) Behlens makes one called PoreoPac.
What are you using for a finish?
I'm assuming by the tone of your question, you skipped making a sample board and proceeded directly to the piece. Welcome to the learning curve. Don't feel bad, we've all done the same thing at one time or another. A sample is the best time you can spend (and it does take time)
Keep me posted on progress.
Peter
