Minwax® Ultimate Floor Finish Preview

Professional Quality Urethane That’s Incredibly Easy To Use

Over the years I’ve spent countless hours applying urethane to furniture, floors and trim work. The task was often tedious, extremely odorous and difficult to get professional looking results. Also, because traditional “clear coatings” on wood involved solvent-based polyurethanes cleanup was extremely difficult and messy. I’m happy to say those days are just about over with the development of water based coatings.

I recently had the opportunity to use Minwax® Ultimate Floor Finish on some Southern Yellow Pine stair treads and the results really impressed me. Many of you may not be overly excited about a water based “urethane” but I think you really should give it a shot.

Ultimate Floor Finish Features

The following are a few of the features and benefits from the Minwax® Ultimate Floor Finish:

  • Provides a crystal clear finish – unlike more traditional urethane products, Ultimate Floor Finish is crystal clear so it won’t change the natural color of wood.
  • Self-Crosslinking technology ensures a tough floor finish.
  • Non-ambering
  • DIY Friendly
  • Recoat in only two hours allowing some projects to be completed in one day
  • Does not require sanding between coats.
  • Exceptional flow and leveling – easy application
  • Lower in odor than traditional solvent-based polyurethanes
  • Cleans up with soap and warm water

Using Minwax® Ultimate Floor Finish

As I mentioned earlier I used the Minwax® Ultimate Floor Finish to finish a set of basement stairs in my home. The stair treads are Southern Yellow Pine which is a very light colored wood (great for testing how clear the finish is). Applying the finish to the stairs included the following steps:

  • Light sanding of the wood treads with 220 grit sand paper.
  • Removing dust and debris with a tack cloth.
  • Applying one coat of Minwax® Sanding Sealer.
  • Applying two coats of Minwax® Ultimate Floor Finish (waiting 2 hours between coats).
  • I chose to let the treads sit for a couple of day.
  • Light sanding with 320 grit sand paper.
  • Clean with tack cloth.
  • Apply final coat of Minwax® Ultimate Floor Finish.

Minwax® clearly states you do not have to sand between coats as long as you do not wait longer than 24 hours. I waited longer than that so I chose to sand prior to the final coat. After applying this new product from Minwax® I had the following general thoughts:

  • In the can the product looks like a semi-transparent “milky” liquid. Don’t let that fool you because it does indeed dry crystal clear.
  • The product dries really fast. Within about 30 minutes or so the surface appeared to be dry.
  • I was really impressed with how smooth the surface was each time after applying the finish. The liquid “lays” down really flat and doesn’t show brush marks (I used foam brushes for the application).
  • I couldn’t notice any odor at all from this product.
  • Cleanup is as easy as rinsing your tools and hands in hot soapy water.

Overall Impression of Minwax® Ultimate Floor Finish

I am totally a believer in water based urethane products now. The Minwax® Ultimate Floor Finish is really easy to apply, dries super fast, doesn’t smell, and it’s very easy to clean up. The finish looks amazing and so far it’s holding up very well with no signs of scratches or blemishes. This is definitely a product I’d recommend for both Professionals and DIY’ers.

    Looks great! Basement stairs never looked so good.

    Is this the same product as
    Minwax 16666 Water-Based Polyurethane For Floors?

    Hello!
    I was wondering though – we have oak stairs in our house which were already stained and there is some clear finish over top. Also, as they curve, there is a kind of ledge in the corner halfway up on which you can put some statement décor. It has a much thicker layer of clear finish.

    I’m wondering if this product would work to refinish/touch up the stairs (which are wearing faster than the ledge, of course), railing, etc. I’m concerned that they used oil-based – I presume I cannot use water-based over top then.

    What do you suggest?
    My staining projects usually involve either untreated wood or something I’ve stripped and sanded, so I’m hoping I don’t have to strip the stairs to just touch up the top coating.

    I was wondering how long ago you completed this project and how the stairs are holding up. So many people say that water based urethanes don’t last as long so I wanted to see how your experience has been.

  5. Ev says:

    Did you find that this finish brought out the grain?

  6. James says:

    Thanks for posting your experience with this product. I was debating if I should use it and your article convinced me to give it a try, I am happy with the results.

  7. Michael Kirkpatrick says:

    What kind of brush did you use?

  8. Laura Manns says:

    Minwax recommends waiting 24 hours for light foot traffic and 7 days for heavy traffic and rugs. We just completed 3 coats of the floor finish in our new home. How long should we wait to move in?

  9. Trace says:

    Is it ok to use it over dark walnut stain? I keep seeing it stated that it’s best to use over light or natural color floors?

  10. Sarah says:

    Thanks for your preview! We have old oak floors and I want to paint them (don’t be mad) and then “distress” them. Do you think this seal would work on top of paint? Acrylic or oil based paint? THANK YOU

    Thoughts on using this product on a dining room table top? I have used this on stairs and love the finish. Durable enough for a table?

  12. Elaine Kell says:

    Can the Minwax ultimate floor finish be sanded before 24 hours if brush strokes or tacky areas are seen.

  13. Elizabeth says:

    I just used this product on my stairs. I stained them a dark gray. After the 1st coat, I noticed small cracks on some steps and not on others. Also, in some areas it had a cloudy hue. I followed all of the directions to a tee, my stairs were completely dry prior to staining and I waited 24 hours before putting the ultimate floor finish (satin) on them after I stained them. I’m not sure how to fix this! I’d appreciate any advice. I’m afraid to put on a second coat.

    Want to use it on support beams in my home & pillars/post will it stay on surface or sag ?
