I built a table top from book-matched walnut slabs. I coated it with BLO because I liked the way it brought out the grain and then topped with General Finishes High performance to create durability. BIG mistake as this was a water based poly on top of the oil and it didn’t dry evenly. (Let’s not beat me up over this ok?)
My next step then was to sand it down to bare wood, reapply BLO but then top with dewaxed shellac before the General Finishes. I did this on a test piece and it looked great. Unfortunately, even with three coats of shellac, the table is still blotchy and I believe it’s because the previous coat of water based finish penetrated and blocked the pores unevenly.
So I’m going to sand it down again and am looking for advice on how to get rid of the blotching? Running test pieces doesn’t seem to prove one technique over another as the work piece has been altered so much. So I need advice based on experience. Things I’m considering are:
1) sand off enough to get below the damaged pores. (I don’t know if this is possible as it probably soaked in quite deep in some areas) and start over again
2) somehow even-out the blotchyness by soaking in all the wood with something, presumably water based.
3) revert to an oil based poly but what do I do with the base to bring out the color?
I’m pretty lost here and this is an extremely costly mistake I’m trying to rectify. I appreciate any knowledgeable help.
