Bona NaturalSeal is a waterborne sanding sealer made to keep the look of unfinished wood. A small amount of white pigment offsets the darkening a clear coat normally causes, so the floor looks raw even after it is sealed and finished. Bona pairs it with a matte finish such as Traffic HD RAW or Traffic HD Extra Matte.

Where to use it
On bare, freshly sanded wood where you want a natural, unfinished look. It is not recommended over stain. The sealer itself is non-yellowing, but a yellowish tint may show through if it is used with oil-based products.
How to apply
- Shake well before using. Do not thin.
- Apply with the grain using a Bona floor coater (T-bar), roller or cut-in pad, keeping a wet edge.
- Hold the coverage rate. Do not spread it too thin; uneven coverage can cause blotchiness or color variation.
- Let it dry, then apply 2 coats of a Bona waterborne finish. Use a separate clean applicator for sealer and for finish.
- Abrading between coats is not needed unless more than 48 hours have passed. For the smoothest result, abrade with Bona Conditioning Pads and 180–240 grit Bona Diamond abrasives.
Results vary with wood species, especially oily and resinous exotics. Always prepare a sample or test area first.
