Used this on natural white oak as the oil-based poly I used on test scraps yellowed the wood more than I was going for. This slightly darkened the white oak, just a little, which left it pretty nice with no yellowing, as this is water-based. Spraying it on with a cheap HVLP spray gun attached to my air compressor, it was fast and easy to get 4 coats on. It leveled very smoothly and flat. Dewhisker your project first as this is water-based and it'll raise the grain of the wood. I did that by spraying it with a water bottle, waiting half and hour, and then sanding it flat. After the first two coat of this polycryclic, I also LIGHTLY sanded the surface with 400 grit sandpaper on a sanding block - very slightly swipes over the surface, just one or two swipes, and that took it down smooth. Following coats did not need any sanding. The Ultra Flat barely has a sheen to it, which is what I was going for. Glad I went with the Ultra Flat! Will definitely be using more of this in the future.

It's polyurethane it does its job.

I put this on a butcher block table in my ceramics studio that frequently gets wet. Water wipes right up, and my dark clay doesn’t stain the surface. It didn’t change the color of the wood very much, which is what I was after. I used about three coats, sanding in between each one, and it’s been incredibly durable so far.

I am constructional professional and use a variety of application-driven finishes in my personal and professional life. I recently built a range-hood for a residential kitchen remodel that required a smooth, flat finish. Minmax's Ultra-Flat Polycrylic seems like a reasonable choice. The prep process is simple- dependent upon your substrate; in my case, right over latex paint that had been drying/curing for 2 days. Application was straight-forward with a note- water-based clear finishes afford very little working time before they tack. For a large surface- particularly a large, flat surface, you have to work quickly and methodically and know when to not over-brush/roll. Once the bristles or nap start to stick/resist, you're done! I find that Minwax finishes do a solid job of self-leveling/smoothing so once you feel the drag, stop and let the product lay itself down. You get some inherent assistance by formulation since it applies kind of cloudy/milky out of the can and turns more translucent, to ultimately transparent as curing/drying takes place. As you can ideally see in the project pictures, after three coats, the finish is smooth and homogenous (even though over intentionally semi-rustic surfaces). Polycrylic has some "build" to it, so if you like it to look like a coating as much as sheen, you're good to go- with more coats making for more of a film-feel. The film-build can present a challenge if you're tape-masking. Be careful not to peel your finish off by timing your pull correctly, or carefully scoring transition lines. Clean-up is super simple since its water-based; a little soap, water, and work and brushes/rollers/tools come perfectly clean. However- and the reason for the one star ding- as you can hopefully also see in the pictures, I am not sure I agree with "Ultra Flat." It generates more of a matte finish. A true flat clear- especially "ultra" flat- is exceedingly difficult to achieve and may require some mechanical abrasion/scuffing to really knock down sheen. All-in-all, I am pleased with the product and its performance thus far.

Finish was exactly what I was wanting. Stir it (a lot) to get all of the clumps dissolved.

I use this for projects I make and sell from small decor to painted resin jewelry. I have read the satin and glossy finishes offer better protection so I do several coats with that first and then finish with this ultra flat. It isn't available to buy in store anywhere near me only the satin and glossy are. I would highly recommend it as one can really does last for many projects.

Love this brand of polyacrylic and needing an ultra dull finish which is harder to find

I am grateful to Minwax for making the polycrylic in "ultra flat". When I used "flat" it was too glossy. It saved my furniture painting project.

He usado este producto antes y me encanta, pero cuando recibí mi pedido dentro del paquete, la lata tenía un problema y la mayor parte del producto estaba en la bolsa, no en la lata. El empaque debe ser mucho mejor.Tuve que devolver el producto dañado para obtener un reembolso.

Great product very durable and easy to use. Leaves an excellent protective coat with no sheen. Excellent water clean up.

Arrived on time and great product for matt finish.

Time will tell how it lasts but all good at a few weeks

Bought this after seeing DIY youtubers in america use them with great success. I'm onto my second tin now, and even though I use it very often, I still get about a year out of each tin. It's super easy to apply, very clear, very strong and has a great finish. I use them for craft projects, Christmas baubles and furniture makeovers. I love that even beginners can use it successfully and there is a huge margin for error, and it doesn't show streaks and brush strokes hardly at all. Very happy!

I bought this because I put a matt polyacrylic on a cabinet I painted. After re painting again in chalk paint I coated with the Miniwax ultra flat and it has dried with a shine on it!!! Really dissappointed and I have just wasted my money as it is just as shiny if not more then the matte polyacrylic I applied!!!
