General Finishes High Performance is one of the hardest, most durable consumer polyurethane topcoats on the market today. It is non-yellowing and offers easy water cleanup. This is the flat version, with almost no sheen at all, and is ideal for antiques, rustic furniture, milk paints, or any application where a protective layer is needed without adding gloss. It contains all the consumer-friendly characteristics of PolyAcrylic Blend. In addition, it contains a UV Stabilizer to protect it from breaking down in sunlight and to protect the underlying stains from fading. With its pure polyurethane durability, it's a great choice for hardwood floors.


Direction for use:

  • Oil-based stains must be dried for a minimum of 48 hours before applying General Finishes High Performance
  • Use a foam brush or paint pad applicator
  • Apply enough material to provide a wet film, using smooth, even strokes with the grain
  • Sand between coats using 320- or 400-grit sandpaper
  • Remove dust before recoating
  • A minimum of 3 coats is recommended, with additional coats for increased durability and depth

Great product!
I love the product. Application was so easy and while I'm a very neat person, I know the table is now truly protected from spills. It was easy to apply, quick drying and makes the grain look beautiful. I applied 3 coats as per the instructions. I was originally going to apply flat out flat after application to make it look even more like the original finish but this product leaves such a light sheen that I don't know why anyone would be so anal as to actually do so. I purposely paid good attention to the look of the table before I applied the product and I think this product truly had minimal impact on altering the woods appearance which is great. I love my table!! Woohoo!

Eric J on Mar 10, 2016
I used this product over the gel stain. Worked very good, it did give more of a glossy finish than I wanted but still looked good. Very durable.
Lisa W on Mar 6, 2016
I'm painting my cabinets white, and then antiquing them with a glaze. In order to seal the paint and glaze to a durable finish, I needed a product that is non-yellowing, which is extremely hard to find, as well as a product that is matte, since matte will look best with the antique look. Glad I finally found this product! Can't wait to get started!
Jana S on Mar 3, 2016
We chose this to place a top coat on the flat black that we painted our fireplace. Then, we decided to use this as the sealant for the dresser we distressed. While doing so, we ran out since we originally only bought the pint for a smaller project. Very happy with it so far!

SHERRI R on Feb 3, 2016
Needed as flat (no sheen) finish as possible...
Adam P on Jan 22, 2016
I have used this before and is the best polyurethane I have ever used. Although it says flat, the finish is really more of a soft satin finish. I think it is the perfect finish for the projects I do which is mostly small tables and benches.
Walter L on Jan 13, 2016
Using with Java gel stain. The satin topcoat had a little too much shine for my wife's preference.

Donna T on Jul 5, 2015
Have heard more than a lot of great things about this product, and is one of the few poly finishes I can find that is flat and not "satin". I want a zero-shine finish. I've also heard buffing this with #0000 steel wool makes it look even more flat.
Eric M on Jun 16, 2015
Gives a look similar to a wax finish and doesn't streak like a lot of products do. I can add a little distilled water if its dragging and drying to fast.
Nona M on Jun 14, 2015
Washable.
Amber K on May 31, 2015

Can this product be used on General Finishes High Performance Polyurethane Top Coat? The directions for the Extender says it can be used on any water-based finish, but the webpage for the High Performance Top Coat on this site says not to thin. Confused.

Can this product be sprayed with a HVLP sprayer?
Troy M on Aug 18, 2016
BEST ANSWER: It must depend on your sprayer. I sprayed it directly from the can (no thinning) with my Fuji Mini Mite 4 sprayer with no issues and had fantastic results.
Would you recommend this over a chalk painted piece to match the look of waxing it?
A shopper on Jun 18, 2015
BEST ANSWER: Since I'm not sure what you mean by "chalk painted," I'm not sure my application will help you. I have used the three GF High Performance Top Coat sheens in several projects and highly recommend them. I used the flat finish to protect a piece painted with GF's Milk Paint product, which is also a terrific product. If you want to protect your painted project as I did, the High Performance Top Coat finishes would be superior to wax. If you're just trying to duplicate the sheen of wax, you could still do so, but I would recommend that you start with the gloss or semi-gloss product and use very fine synthetic finishing pads to degloss the finish. You will just have to experiment until you achieve your goal.
What will happen if I do not sand between coats?
Carol W on Nov 8, 2015
BEST ANSWER: Being water based, you will get roughness from raised grain. After the first coat has been sanded you could probably go without sanding if you recoat within a few hours. I'd do a minimum of 3 coats.
Will this resist Sun uv problems any better than Gel topcoat wipe on?
A shopper on Apr 16, 2015
BEST ANSWER: Yes, it contains a UV Stabilizer to protect it from breaking down in sunlight and to protect the underlying stains from fading.
While everyone is using this product over a finished wood, can it be applied to raw wood successfully without ambering over time?
Laura L on May 20, 2017
BEST ANSWER: This has been the clearest finish I have used. I have not seen any amber tint yet and it has been a couple of years. And yes, it can be put over raw wood
WHAT IS THE DIFFERENCE BETWEEN FLAT HIGH PERFORMANCE POLYURTHANE AND FLAT OUT FLAT TOPCOAT?
jane a on Aug 30, 2017

Can I use this over oil based paint?
Kim M on Apr 13, 2019
BEST ANSWER: I have applied this finish over many old finishes with no problems. I am sure many of them were oil based paints and other oil base finishes. However I have not applied oil base paint and then covered it with this finish. In my opinion this product will seal and provide the perfect finish on any previously painted piece. It is the finish I use on all my projects no matter if it made with new lumber or reclaimed lumber with old paint.
I would like to use the flat finish on my floor but someone told me that flat finish would not hold up well. Should I use a satin finish instead?
SherryGore G on Feb 15, 2018
BEST ANSWER: I would highly recommend this product for floors. As far as the 'flat' finish goes, I noticed that this is actually more like satin. I think it's somewhat true that in order to get a truly flat finish, the durability will be compromised, and it will burnish and scratch easily, based on some other brands I've tried that offered more of a flat finish. They just seemed 'softer' than this product, and I wasn't impressed. I would recommend this product for floors. If you don't mind a slight sheen, you will love it. You will get a satin finish, in the end, but this stuff holds up amazingly well.
Can you apply this over oil based stain ?
Lisa R on Feb 9, 2019
BEST ANSWER: But it says it’s water based , this is why I’m confused ??
I'm just a little confused. This is a water based product but you're calling it a "polyurethane." How is it different then a polyacrylic? Because I am looking .
A shopper on Jun 23, 2015
BEST ANSWER: Polyurethanes can be oil or water based. I'm not sure how it differs from Polyacrylic. I'd contact GF specifically. They were very prompt and helpful with answering all my questions. I can tell you I used the HP in Flat for kitchen cabinets (over their gel stain) and was very pleased. I originally bought the Satin, but the sheen appeared semi gloss to me and wasn't the look I was going for. IMO, the Flat finish is closer to a Satin. It's very easy to apply. I used a foam brush. You don't have to overwork and it self levels. I did four coats on my cabinets and they're holding up very well 6 mo. later. Dries very hard. Easy clean up since it's water based. Hope that helps!
I used this product for a counter/bar area on walnut. I have 6 coats but it still appears thin will this be durable enough for drinks etc? Or should I apply something like minwax and buff?
Marco O on Apr 8, 2018

I have a natural cherry table top for a dining table. I've heard polycrylic will not bring out the natural beauty of cherry. Can this be used over a tung oil or something like that which would first bring out the beauty, then the polycrylic would protect it from moisture etc?
Eric S on Nov 1, 2015
BEST ANSWER: This would serve the same protective purpose as polycrylic, so there would be no need to use both. This goes on more smoothly than polycrylic. They have excellent customer service- I would call and ask about using over tung oil. My guess is that it shouldn't go over oil.
can i use this product on flooring?

BEST ANSWER: yes
is the general water base polyurethane available in gallon sizes?
dan b on Nov 5, 2017
I put an oil based polyurethane on my wood floors. My dogs have scratched the finish - and I may have put it on too thick in some places. I want to take it off and replace it with something that doesn't show scratches so obviously. The wood doesn't seem to be scratched. What would you suggest?
