Hey Gang, I was asked to finish an 8 foot long, 16 inch wide walnut slab to be used as an serving/eating bar in a friend’s kitchen. She wants me to retain the cavity area and fill it with a clear resin. The cavity has a partial bottom so I would need to create a temporary dam on the underside until the resin hardens. I have never done this and have lots of questions.
First thing is what are some recommendations for filling this void with something clear. Are there epoxy kits manufactured just for things like this? What finishes are , or are not, compatible? I wonder if the stuff I routinely use (General Finishes Arm-R—Seal, or Waterlox) may cause “fogging” when applied over clear filler. (I plan to contact the finish manufacturers for compatibility questions once I determine what I’ll use for the filler but I wonder if anyone out there has had any success or failures trying this).
Can these fillers be sanded without leaving scratches on the surface? (I have decent sanders and a wide selection of papers). Do the fillers always adhere to the wood or can they separate due to humidity induced wood movement? The slab was kiln dried but is residing in an uncontrolled environment (lumber dealer) right now. At my house it will also be at ambient humidity but my friend’s house will be air-conditioned.
