Foundation ArmorArmor AR350 Low Gloss Wet Look Concrete Sealer 5 Gallon - Professional Grade Color Enhancing Solvent Based Acrylic Sealer for Exterior Concrete and Pavers - 50 VOC

Great product to seal aggregate patio. Restores shine. Easy to apply. Dries in about 3-4 hours.

I had a new exposed aggregate patio poured this summer, and knew I wanted to seal it both for protection and the color that it brings out in the material. When dry, my patio appears grey with brown exposed pebbles...but when wet appears brown which is what I wanted. After days of research, I settled on this product. To make application easier, I bought a roller frame, 4 foot extension handle, a paint tray plus 2 disposable inserts, a couple of 3 inch paint brushes, and a 6 pack of 3/8 inch roller covers. After completing the project, the only thing I would change is to say that you will only need one roller cover for each application.I prepped the patio by sweeping it several times before the first application to remove dust and debris (new patio, so I did not see the need to power wash). My space is bounded on 3 sides by either house or iron fence, and I planned to work towards the open edge as I went. I found it easiest to cut in 3 of the bounded sides of the patio by hand with a paint brush. I then poured some of the 5 gallon can into the paint tray and went to work methodically working in from all the edges while making sure I did not apply any behind me. It went on quickly and easily, and I got any excess of the roller in the tray before applying so there would not be any pooling on the concrete. I worked my way to the open edge to finish things off. The takeaway from the first application was that sweeping the patio was not enough to clear all of the small debris. I ended up with a fair amount on the roller, and had to pick pieces of grass out of the sealer as I went. The whole first application took me less than an hour start to finish on a 225 square foot surface.I waited the required 24 hours for the second application. I knew I needed to get the invisible debris off the patio better this time, so I decided to use a leaf blower to work out towards all the edges. I repeated the application just as I had the prior day, starting with cutting in all the edges with the paint brush. I finished the second application in about 40 minutes, and found hardly any issues with debris on the roller or surface. The leaf blower was a success, and I recommend it wholeheartedly.The surface sheen looked uneven after the first application, but looked great after the second. I am extremely pleased with the result...a matte finish wet look. Water now beads on the surface when it rains, and the patio looks amazing. I will definitely be using this product in the future, but probably in smaller quantity. I used maybe half of a 5 gallon for the entire project.

I can't rave enough about this product. I have an exterior patio to our house. It's a fairly large patio and has flagstone natural stone throughout. Our house is about 13 years old and the stone was all dull and the stone has lightened considerably. It always looks dirty when dry but when wet looks really great. That's when I started researching online products that will darken stone and seal it and give it a wet look. I saw the great reviews on Amazon as well as saw some videos on YouTube.I was still a bit skeptical as the product isn't cheap at $225+ plus all the supplies and also the time. But I figured it would be worth the investment to try it. First step is I power washed the entire flooring with a SunJoe power washer (excellent that I also purchased on Amazon). I let it completely dry 2 days and then I got a sprayer and sprayed down the Armor AR350 and then took a roller and evenly distributed the solvent.Immediately I saw it darken the stone and gave it a wet look. I got tempted to just use one coat as it looked great with one coat. But I followed the instructions and I put down another coat after 24 hours. I'm glad I put down a 2nd coat as it looks better with another coat and I'm sure it will last at least another year with another coat.It totally waterproofed the stone and water beads up. I think it will be much easier to clean the patio as dirt can't easily stick to the stone now. I did an entry way as well as the entire outdoor patio. It's about 1,500 sq. feet and I just had enough with the 5 gallons to do 2 coats.My wife was skeptical before I started but she is so happy that I completed the project. There is a bigger satisfaction because I did it myself. This is a really easy DIY project and well worth it. I posted some before and after photos.

I've used this sealer for a few years now on my patio. It is easy to use-for me the hardest part is finding two days in a row with no rain so you can wash the surface one day and give it 24 hours to dry before applying this sealer the next evening. It is important that you wait until the sun has set and the surface temp is below 85 degrees....hotter than that and you will get bubbles. (I have, and they pop easily and you won't notice where they were after that, so not a huge problem.)While it does "last," meaning that it's still there after a hot summer and crappy winter (I'm in NE Ohio,) I find the sealer dulls after a year. (See the pic where I've applied fresh sealer in comparison to last year's sealer.) Because it looks so amazing with a fresh coat, I do mine every spring.I simply hit the patio the day before with some Simple Green, use a surface cleaner with my cheapie electric pressure washer, and then rinse off with a wide nozzle. (You could get away with a brush and a hose.)I use an 18" roller and get great results, and I can knock the job out in an hour or so.This year I added Foundation Armor's fine anti-slip additive and it gives my patio a bit of grit to make it less slippery when wet. I just added some to the roller tray after each refill and mixed it in with a paint stick.The sealer works good. I wish it would last a little longer so I could do the job every other year, but I'm addicted to the new shiny look it gives to my patio every spring. (People are shocked to hear my patio is seven years old now!)
