Bona Dri-Fast sealer is designed as base or primer coat only! Just because it says “sealer” in its name doesn’t mean you should use it for all your coats. In the wood floor world, “sealer” refers to the first coat that goes onto the bare wood. These are formulated to be runnier and they bond into wood better than the higher-solid topcoats. Topcoats also bond better to this than they do to the wood itself.
The value of this particular sealer is that, even though it is an oil-based (aka solvent-based) finish, we can use it under either oil-based or waterborne topcoats. Yes, really. We use it as a way to get that beautiful, warm amber color that oil-based finishes give to wood, while allowing us to use better, stronger, and much less toxic waterborne finish coats over the top. We aren’t using this off-label – it was designed to do this! That makes Bona DriFast our favorite “amberizer” under all the Bona topcoats that we sell (Mega and Traffic) and under all the Pallmann topcoats (Pall-X 96 and Pall-X Power). It plays well with others.
But, you still have to be careful – jumping from one solvent base product to another still must be done thoughtfully. The label may say “DriFast”, but if you plan to use it under a waterborne topcoat, you have to wait a full 12 hours and you must lightly sand it at 180grit, and then remove all that sanding dust.
