How To Use Grain Fillers – Finishing 101 Series

How To Use Grain Fillers - Finishing 101 Series
To achieve a smooth and mirror like finish on open grained woods, you should use a grain filler. In this video I show you how to use the grain filler from Aqua Coat.

– Sand the surface to 150 grit using my orbital sander
– Apply a seal coat of dewaxed shellac to two of the 3 sample boards
– Apply stain/dye to the third sample board. When the stain/dye dries, apply a coat of dewaxed shellac.
– Using a plastic spreader, apply a very thin coat of Aqua Coat grain filler, wiping off the excess across the grain. Let it dry for 45 minutes to an hour.
– After the first coat of grain filler dries, sand the surface with 320 grit sandpaper.
– Apply 2 more coats of grain filler the same way as described above and let it dry.
– Apply your top coat of choice.

  1. Why would you pay for oak wood if you want to fill in all the grain and then paint it (not stain it)? Why?

  2. Can you do a video to fill the pores with Aquacoat, followed by staining to color matching the filled pores?

  3. I've seen quite a few demos with this product, but this is the first I've seen that uses a shellac sealer first. Any particular reason/benefit for sealing with shellac before the grain fill step?

  4. Great video with lots of info.
    Would you advise this grainfiller also on burl? I need to finish some boxes with maple and walnut burl veneer and think this could be a solution for a smooth finish. Do you have any advise?

  5. Interesting what a difference that makes, especially on the painted piece. Good video!

  6. Thanks for the demo on how to use grain fillers, Sean. I noticed you applied it cross grain, I presume that with the grain would drag it out?

  7. Great looking finishes there Sean. I'm going to have to try that Aqua Coat out myself.

  8. Wondering if this filler would work on a turned bowl? Seems like it should. Would be especially helpful on oak pieces.

  9. That one reason i hate working with oak is finishing never turns out the way i like. Have to chk this stuff out thanks Sean!🍻👍👍
