Zinsser Bin Shellac is a high VOC sealer that will seal the off gassing and bond well to most oil-based polyurethanes. Unfortunately, it takes about two weeks to off-gas. However, our AFM Polyureseal BP will block the emissions and bond well to the shellac and provide a better abrasion resistant surface. Yes, this is an expensive two step process, but it beats the expense and huge mess involved in sanding off the oil-based poly. It's the only solution we have found that works.
