Product Overview
The Armor SC25 is a proprietary water-based Siliconate water repellent and impregnating sealer for white or very light concrete. It penetrates and chemically bonds deep within the substrate to form a hydrophobic barrier within the pores. It provides long lasting protection against deterioration or staining caused by water absorption, salt and freeze-thaw cycles. Once sealed, substrate become less susceptible to cracking, spalling, pitting, staining, mold, mildew, algae and efflorescence. The Armor SC25 will not impair the natural breathing characteristics of treated substrates, nor will it produce a film or coating.

Stay Away. Ruined my nice new floor. DO NOT BUY!!!!
Followed directions to the letter. Etched floor. Waited. Applied this product. Went on like water and left streak marks all over. Whatever mist or splash that got on the surrounding area left marks. I rolled on as well as sprayed. Rolling left ridiculous marks. Spraying didn't help either. Left splatter spray where I stopped and started. Brushed out puddles as directed. I let it dry and came back to find massive white marks all over my new floor. See photos. Did NOT dry clear as advertised. These marks didn't wipe off, they needed deep scrubbed to get just some off. Looks like crap. I had to scrub all day to get what I could off. I believe the product scrubbed off as well because it doesn't bead water anymore. $200 for 5 gallons. Glad I only used one. I'm taking the rest back for a refund. Total waste of money and time. Find something better than this crap. Keep searching.

I did some research on penetrating sealers and decided to go with the Foundation Armor to seal my new concrete garage floor, sidewalk, and patio. It has only been on for 2 weeks so we will see how it holds up after 2 years but it is performing as expected so far. The application process was as simple as it gets, pour it into a garden sprayer and spray it on the concrete. Soaks in and is dry in about an hour. Instructions say to give it 24 hours before driving on. Cement dried back to it's natural color for the most part. In a couple of spots I applied too much product and it left a white film, but no big deal... just got out my stiff broom and it came right off with a little pressure.
Picture is of my exterior sidewalk, water beads right up.

Premium price for mediocre performance.
I bought 2 gallons of this stuff to seal my 250 sq ft garage. I scrubbed two thick coatings of this sealer with a brush and still water finds its way in the concrete.
As of now I do not recommend this product to anybody.
Foundation Armor you need to step up your game.

This is the second time I have purchased this product. The first time was for my garage floor. This time it is for an outdoor patio and sidewalk. We prefer the natural look of concrete so we chose the clear/matte finish. The product does sink into the concrete instead of building up a barrier that sits on top of it. So there is no chance of peeling. So far, so good. We have had a little rain and my dog has added his two-cents worth. In both cases, everything beaded up. It is easy to keep clean with regular sweeping and occasional hosing off. I definitely recommend this product.

I needed something that got rid of this fine powdery dust after my floor got wet from a recent hurricane, so I gave this a whirl. It didn't completely eliminate the dust, but it definitely reduced it. So the white footprints everywhere else aren't so prominent anymore.
Simple prep, I just vacuumed the dust up. Easy application, I used a 1gallon sprayer. Technical support was very helpful when I called to get clarification on drying time, although they did unfortunately interrupt the best Journey song EVER while I was waiting in their phone queue (for about a minute). The only fault I have with it, is the high price.

I used this product today on my garage floor and it was nice. Very easy to use, spray on really good. My floor looks nice. The reason that I did not give it 5 stars is the cost. Other than that it a good product.

I recently applied 5 gallons of SC25 to a new broom finished concrete driveway with a garden sprayer. This product was extremely easy to apply and the finished product was exactly as is was advertised with excellent water repellency. The Foundation Armor customer service department was extremely helpful with their product selection.

I've recently had new pavers installer across the front and along the side of my property. To protect the work from future staining, I wanted to seal them. After searching the internet, I came across Foundation Armor. I'd like to say that it applied as easily as indicated. Because it's a water based penetrating sealer, it didn't change the appearance of the papers and clean up was with soap and water.
