Rated 5.0 out of 5.0 by Amazing find! This was in my local store's new special buy area in the front of the store. I just happened to walk by and notice it. My wood stairs on the porch were in rough shape so I need to give them a real good cleaning. More important was how I was going to protect them after. I used outdoor bleach and a pressure washer to clean the mildew (see pictures). After letting it completely dry for a day I came back to apply the Armor Waterproofer. I was a little nervous because instructions say weather has to be at least 50 degrees, I was at 52 since it is late fall here in New England. Application is easy. The nozzle cleanly pours out the product and does not make a mess. The liquid product goes on milky white so you can see where it has been brushed. It fully dries clear and you wouldn't even know it was on the wood. I went out 2 days later to pour some water on the wood to test it and it beads up perfectly. I am very happy I purchased this!

Rated 5.0 out of 5.0 by Works quite well, excellent value This product works quite well. I applied this over freshly powerwashed and pointed (tiny missing mortar bits fixed) brick. Before application, the brick absorbed water like a sponge. After application, water beads up amazingly well and literally rolls off. It is water-based and appears to be best applied as a fine spray in a light layer. The instructions stated to back brush, but I found it better to wipe over it with a cotton towel as it absorbs excess drops of this waterproofer. Excess waterproofer will leave spots on the brickwork if dries so it is best to remove it while wet. If you spray near windows, it is a fair bit of work to remove it - either any decent cleaner when wet or elbow grease when it is dry. After 24 hours, it works quite well. I cannot tell about its longevity, but me and my mother managed to do an entire 1 story brick house in one day. Used total 5 gallons - better coverage than expected. More work than expected, but the results are well worth it. June 7, 2014
Rated 5.0 out of 5.0 by Applies easily and seals wood great. Really like this product. Easy to apply and clean up. Seals wood great and water really beads up on treated surface. Has not discolored or changed the wood color at all. April 2, 2014
Rated 5.0 out of 5.0 by this is the best for the best price This is the best sealer out of 3 products i tried. This spring I pressure washed my sidewalk , driveway and patio. not knowiing what the coverage would be I purchased this product first. I only bought 2 gallons and needed 5 to do all my areas, i had a gallon left over frrom last year. I returned to Home Depot in my local area and they did not stock this brand. I bought 2 additional gallons of another product and paid twice the cost of the first.The following day it rained and to my suprise this sealer at half the cost of the next one beaded water while the $20.00 plus product looked like nothing was applied. I hope it stands up in the long run but at first glance this is what I will use on all my concrete work in the future. Make sure you check locations before you go out in search as i found it in only 2 stores in the Portland market that carry this specific brand. I hope all stores switch to this product but in the mean time I will buy enough to do my home next year in case Home Depot decides not to carry it in the future. Regarding ordor I used it outside so I guessed at the low odor question. Value is outstanding and coverage is as advertised. May 3, 2012
Rated 5.0 out of 5.0 by Good Value; Seems to Work Well We put this on our patio and sidewalk -- large area with brick pavers. Used a sprayer on the patio which was much easier than using a roller (which I did on the sidewalk). Product went on easily, dried quickly and seems to be working. We had no discoloration. The patio was powerwashed first, to remove all debris and discoloration. I realize these products don't last for years but our hope is that the patio and sidewalk will be protected somewhat. This product does not give a glossy can't tell it's there until the water beads up. Photo shows beading after an overnight rain; some of the water has evaporated. June 23, 2013
Rated 1.0 out of 5.0 by Not for shaded concrete I put this down on an area that gets a fair amount of shade and mildew tends to grow on the concrete. I cleaned the area with a clorine solution and stiff bristle broom and let it dry a week. After applying this the water beaded up longer than Thompsons Water Seal or another sealer that I had professionally installed. However, the area coated seemed to look like the concrete was wet underneath, and takes forever to dry. The mildew returned withing 2 months worse than 9 month's untreated!!! Not sure I have the time to remove with mineral spirits - hopefully it dies quickly. I would never use again. Thankfully I only used 1 gallon as a test. January 20, 2015
Rated 1.0 out of 5.0 by Not for Concrete I cannot recommend this product for any sort of concrete waterproofing. It does bead water but it also discolors the concrete. Getting it off once applied takes 3x as long as putting it down. May 9, 2013
Rated 3.0 out of 5.0 by Seems to be effective and protective I applied the armor clear to a piece of wood that I had attached to a garden hose reel cart to create a stable surface, so that the cart would not tip over when I pulled out the hose. So it was to remain outside on a continuing basis, and would get wet whenever the hose was in use. Firstly, the quantity 1 gallon, for the price, 10 bucks, made this a great value. The sealant/protectant went on easily with a paintbrush, the drying time was fast, and the clean up was a snap. The liquid however was watery thin, and was absorbed into the pores of the wood. I would have preferred a thicker, gooier, varnish like substance that encapsulated the surface of the wood to create a thick impermeable membrane. I may apply several additional coats to create a thicker barrier. So far the water for the most part does bead up and run off rather than soaking into the wood, but only extended time outside will determine if this product is as effective as it claims to be.
