About This Product

The Armor SX5000 is a professional-grade solvent-based silane-siloxane water repellent concrete sealer. It chemically reacts below the surface to form a hydrophobic barrier that helps to reduce damage and deterioration caused by water absorption. It will not leave behind a surface film or coating, and will help to maintain the natural, unsealed appearance. The Armor SX5000 is a great choice for porous, unsealed, and properly prepped concrete, brick, pavers, and most natural stone.

Highlights

  • Penetrates below the surface and chemically reacts within the pores to create a hydrophobic water-repellent barrier
  • Works below the surface without creating a visible film or coating and is designed to maintain the natural look, color and feel of properly prepared surfaces
  • Reduces the absorption of surface water, therefore reducing damage and deterioration caused by surface water absorption
  • Easily applied to a properly prepared surface with a solvent-resistant pump sprayer
  • Designed for use on porous, unsealed, and properly prepped concrete, brick, pavers, and most natural stone
  • Helps to reduce damage caused by freeze-thaw cycles, and water absorption from the use of de-icing salts
  • Helps to reduce the formation of mold and mildew, by reduce water saturation of the concrete
  • Can last below the surface for up to 7-10 years; however, reapplication may be needed sooner on more porous or heavily exposed surfaces to maintain optimal hydrophobicity.
  • Great for driveways, walkways, patios, pool decks, and more
  • Online price includes PaintCare fee in the following states: CA, CO, CT, DC, ME, MN, OR, RI, VT, WA

Questions & Answers

Does it contain any acetone product
BySep 24, 2026
1 Answer | 
Answer This Question

The SX5000 solvent formula contains a significant amount of acetone and should be applied with an acetone pump sprayer fitted with EPDM rubber seals and hose.

    Coverage by footage
    BySep 3, 2026
    1 Answer | 
    Answer This Question

    Coverage depends on surface porosity. A gallon might cover 80 to 100 square feet with two coats on porous concrete(example: brushed concrete) vs 200+ square feet with just one coat on a denser slab(example: smooth/slick garage floor). If needed, a 16oz sample can be purchased to confirm results prior to placing a larger order.

          how do you apply it ? with a paint roller ?
          ByAug 22, 2026
          1 Answer | 
          Answer This Question

          It's best to apply with an acetone resistant pump sprayer fitted with EPDM seals and hose (example: Armor Sprayer). It's too thin to roll and dries extremely fast, so spraying is best. Sprayer should have a .5gpm nozzle (fan or adjustable cone).

            expected square foot coverage by gallon
            ByAug 20, 2026
            1 Answer | 
            Answer This Question

            Coverage varies depending on surface porosity. On porous surfaces, a gallon usually covers around 90 to 100 square feet with two coats. Very smooth/slick power troweled surfaces might only require one coat and a gallon could cover 250+ square feet.

              Can this be used on color concrete that has not been sealed
              ByAug 18, 2026
              1 Answer | 
              Answer This Question

              Applying the SX5000 to concrete that has an integral color(mixed in) or an acid stain color should not an issue. For other concrete color products please check with the color manufacturer.

                How long after you seal it can it be driven on? I’m in Southwest Florida.

                1 Answer | 
                Answer This Question

                It's best to wait till the following day before driving on the surface.

                  SX5000WB is a Great Product
                  I wanted to seal both stamped & regular concrete to protect my investment of patio, walkway & driveway. I read through multiple product reviews & found that the SX5000WB should meet my needs. The concrete was installed 7 years prior & no one had re-sealed it since the original installation. I power washed all surfaces in preparation to remove a buildup of dirt that had collected. Once the surfaces dried completely, after a few days, I began the application process. I wetted the surface with the product, using a pump sprayer & back rolled as I progressed using a 1/2” paint roller on an extension pole. I only applied a 40-50 sq ft section at a time, so I could assure that the surface was coated appropriately. This worked out very well. I made sure the temperature did not exceed 85 degrees. During the 1st rain, I was pleasantly surprised about how well the water beaded up & ran off rather than soaking in as it had previously been doing prior to sealing. The ordering process was easy through the website & the product did not cost anymore than had I purchased it @ a big box store. Shipment arrived in just 3 days. There are other less expensive products out there, but sometimes cheap is not the way to go. Especially when you consider your preparation time or longevity of not having to re-apply in 1-2 years for a lesser quantity product. I strongly recommend the water based SX5000WB for ease of application, durability & easy cleanup. You won’t be disappointed.

                    Hi FredUtah, thank you for being a repeat customer! We are happy to hear that you loved the product so much that you came back to order more! I know there were a few programs that were ongoing but have since ended. Home Depot had a program a couple of years ago where they offered $1,000 to one reviewer for posting a photo! Hopefully programs like that will be offered again! I hope you have a great day!

                      Great product
                      I recently used Foundation Armor Solvent Base Concrete Sealer on my driveway and patio, and I’m thoroughly impressed with the results! This sealer is a game-changer for anyone looking to protect and enhance their concrete surfaces

                        Used to seal my driveway.
                        We live in a mountainous snowy area, so protecting our driveway was important. We used this product. It worked. As a bonus, they provided a $10 refund for submitting a review - think of it as a a $10 discount to make the pricing more inline with other options! Score!

                          Water Beads!
                          We put this down a couple months ago and it PERFORMS! Keeps the water beaded and off of our concrete beautifully. I've never seen anything like it, it's like wax for concrete. You can't tell it's there and it doesn't change the color, but it works great.

                              Sealant was easy to apply and work work with. Coverage was even and dry time was shown in the instructions. I sprayed mine on using a Dewalt sprayer which worked well. Cleanup with soap and warm water was simple and effective.

                                There is absolutely no noticeable difference in terms of appearance. But I think the repellent effect might be working. I followed the directions to the last word, but I am not satisfied because I was expecting at least a slight glow. I think this product is like wearing expensive underwear only you and your significant other know you are wearing a $250 underwear and nobody else notices.

                                  Hawaii has wet issues common to our area. Tried different products but failed to seal for more than 3 months. Got the recommendation of Foundation Armor from a mason friend on the mainland. His years of use and results sold me. The application was easy, followed 24 hours of no moister to let it set and one year later so far it looks like when we first applied. Wow. Nothing better.
