Bona AmberSeal is a specially formulated waterborne sealer for use with all Bona waterborne finishes. This sealer is formulated to give an oil look which highlights the natural color of the wood, minimizes grain raise and tannin bleed, provides a build layer, and prevents the finish from penetrating into the wood surface and and reduces side boanding to prevent panalizing of the individual wood boards. Virtually odorless and nonflammable.
