  • REDUCES WATER ABSROPTION BY UP TO 95%: The Armor SX5000 WB chemically reacts to form a water-repellent barrier below the surface that will reduce the absorption of water and other liquids by up to 95%.
  • WONT CHANGE THE LOOK OR COLOR: Formulated with high-quality US-manufactured resins, the Armor SX5000 WB is designed to protect concrete, brick, pavers, stone, and masonry without changing the look, color, or feel. The substrate will look and feel exactly as it did before it was sealed!

The Armor SX5000 WB is a great penetrating sealer for unsealed concrete, brick, paver, and natural stone sidewalks and walkways. Coverage: Porous Surfaces: Up to 175 FT2/gallon in one coat. Smooth Surfaces (once properly prepped): Up to 200-225 FT2/gallon in one coat. Coverage will vary depending on porosity, surface condition, application method, and the amount of material applied by the applicator. The above coverage rates are estimates and will vary. Two coats are suggested for even coverage and appearance. Less porous surfaces, such as bluestone, flagstone, and slate, may only require one coat. Surface Preparation: The Armor SX5000 WB should be applied to a completely clean and dry surface. If the surface was cleaned with water or pressure washed prior to application, allow the surface to dry for at least 24 hours before sealing. While the surface may appear dry and feel dry to touch, water below the surface trapped in the pores can cause the same issues. While pressure washing the surface is typically sufficient, spot treatment may be necessary for deep or older stains. If a cleaner is used, it is important to make sure that all cleaning residue has been removed and that the PH of the surface has not been altered to avoid the formation of dark spots. If the surface is smooth troweled, or does not easily accept water, acid etching may be required prior to applying sealer. It is always suggested to apply the Armor SX5000 WB to a test area to verify absorption, coverage, compatibility, and project suitability. The Armor SX5000 WB is designed specifically for unsealed concrete and masonry surfaces. Do not apply this product over a surface recently sealed with a penetrating sealer, or previously sealed with a film-forming sealer or coating. The Armor SX5000 WB can be applied over surfaces treated with a Silicate sealer so long as it has been at least 7 days. It can also be re-applied to a surface previously treated with a Silane-Siloxane sealer so long as it has been a few years, and the surface is able to quickly and easily absorb water. Application: A commercial pump sprayer is recommended to achieve the best coverage and results. Be sure the psi is no greater than 20. Use a .3-.5 GPM adjustable cone tip. Sprayer Suggestion: Armor Industrial Sprayer, ASIN B0CDXT17PD. Apply the first coat of Armor SX5000 WB, ensuring the entire surface is evenly saturated. Wait at least 10-15 minutes, then apply the second coat. Do not flood the surface or allow puddles to form, this will result in over application and the formation of dark spots on the surface. Less porous surfaces, such as bluestone, flagstone, and slate, may only require one coat. Substrates sealed with Armor SX5000 WB may be coated with silicone emulsion paints and many oil based paints once the surface has had 72 hours to dry. Testing is always necessary and recommended to assure proper adhesion. Adhesion may be improved if the surface is pressure washed and allowed to dry prior to application. Armor SX5000 WB is not a paint primer. Adhesion of cementitious coatings, stucco, plaster, etc., may be adversely affected. These types of substrate treatments should be installed and allowed to fully cure before applying Armor SX5000 WB. Always test to verify compatibility. Time of Day: The temperature of the air and surface must be 55-85 degrees F during application. If freezing conditions exist prior to application, it is highly recommended that the substrate be allowed to fully thaw. Should this recommendation not be followed, the product may not yield adequate protective properties. Once applied, the surface should be kept dry for at least 24 hours. Clean-Up: Use warm water and soap. Dispose of containers in accordance with local and federal regulations. Technical Data and SDS Sheet: Prior to applying, please refer to the Technical Data Sheet and the Safety Data Sheet posted on the manufacturer's website. If you have questions before purchasing or applying, please don't hesitate to reach out to a Foundation Armor representative.

  • Great value!
Excellent product! Chose to roll two separate driveways, used 1/2 inch nap rollers. Application is very easy, clean up even easier. With two applications, coverage is very even and driveways look great. Water does not necessarily bead but definitely rolls off. Said to last > 5 years, if so I"ll give it 6 stars. ... show more

  • It works exactly as it is described!
I put in a new large double driveway with slightly lighter coloring in the mix about 6 years ago and wanted to maintain the new looking appearance of the driveway as it is a main visual element looking at our house from the street. I did considerable research on sealers and every contractor and company has their own favorite. I also wanted something that did not have to be redone every year or two in order to minimize ongoing maintenance. This product stated it has a life of 7 to 10 years which fit my criteria. I read others reviews, contacted the manufacturer with questions and was satisfied. I used SX5000 WB and purchased a quality backpack SOLO sprayer for application. I applied it to my open face (light brush finish) concrete driveway and patio closely following the recommendations for preparation and application. After three years it has both met and exceeded my expectations and looks great. No dark mold, or scaling, is clean looking, attractive, and quickly shed water for the first year and a half to two. That was anticipated to lessen per the manufacturer though. It still sheds water and drys faster than normal driveways without this sealant but not as it did the first year or two. As I over purchased what I needed and had an unopened five gallons left over, I then offered and ended up doing about half of my neighbors driveway. The difference is so obvious comparing the cleaned and sealed section of his compared to the original portion. Now three years later, I just did a light re-coating on mine again and anticipate water will bead and run off as it originally did. Checking with the manufacturer, they said this was OK as long as it was a very light application as the original sealant is still in the substrate and working. They were super helpful and knowledgeable each time. Lastly, with a good sprayer, and getting the prep work done, and following the instructions, super easy and quick to apply. So, I’m sold, driveway looks great, and this is probably the last time I’ll have to do this. Jack - Rainy Washington ... show more

  • A must for a paver patio
This sealer is truly the best product on the market today. It goes on very easy & works like a charm. I used a 2 gallon pump sprayer & a paint roller to spread any excess. There was no change in color on most of my pavers. Some of my pavers didn’t absorb the sealer like others. Once it cured after 24 hours, I used a scouring pad & light sand paper to remove the excess that dried on the surface. This method worked flawlessly and helped blend with the rest of the pavers. This method caused no damage to the paver itself & didn’t effect the sealer’s performance. After the first rain storm, the water just beaded up as I expected. My recommendation is to use the guide of 1 gallon for 100 sq. ft. not the 175. The pavers sucked up the sealer like a sponge, so be prepared to have extra product to finish your project. It was easy to clean up once finished, since I chose the water based over the solvent based one. There wasn’t anything odor at all. I highly recommend this sealer. It is worth the higher price compared to other brands. Don’t be penny wise and dollar foolish. Your saving on the labor, buy the best! ... show more

  • So far, so good So far, so good
This product was used to seal a new pool deck of Tremron brick pavers. I used a Chapin backpack sprayer (rechargeable) and it worked like a charm. A little “Home Depot” pesticide sprayer will not work because it delivers too little product, and you’ll be stopping every few minutes to re-pressurize the sprayer. You need some volume and to keep going. This product applied exactly as they said. It had almost no discernible odor, sprayed super evenly, and was a “snap” to clean up. The directions are easy to follow and you can’t screw up, you just need a good backpack sprayer. The application coverage was accurate to what they stated. The material did a nice job tightening up the sand between the pavers. The sealant did NOT affect the color, or sheen of the pavers. They look exactly the same as they did before I sealed them. It’s only been a month, so I don’t know how well it will last, but so far it works great. Here in Florida we get a good amount of summer rain, and the water isn’t absorbing into the pavers at all. If it lasts 5-7 years I’ll be back for more and let you know. I did A LOT of research on “sealers” before I purchased this, and believe it’s the “right” product for this application ... show more

  • IMPRESSIVE
This stuff is GREAT. A little expensive, but you obviously get what you pay for. I had bought a small sample of this product about 5 years ago and sprayed it on a small section of my concrete driveway for a test. Over the years that area stayed free of mildew and stains from oak tree pollen while I had problems with staining on the rest of the driveway. I bought two 5 gallon buckets for the rest of my driveway. I applied it with a 2 gallon garden sprayer. It went on easily and has made a tremendous improvement in my driveway's appearance. I will quickly make up the cost by cutting pressure washing costs significantly. I highly recommend this product. ... show more

  • Does a good job
Easy to apply and works great. Was a little disappointed when I first applied, because it seemed like it just evaporated. However, when it rained the water beaded up and I realized it had soaked into the concrete. Seems a bit expensive, but worth the effort to protect the concrete from the weather.

  • Very easy to apply and works just like the company said it would.
First, I wanna say how easy this product was to apply to the driveway. I literally bought a $30 electronic sprayer and it worked perfect. I put on one coat without it running 15 min laterI applied a second coat. It’s been six months and I can definitely tell the concrete is still sealed! There was really no odour and with my particular liquid does not change the finish of your driveway stays the natural color. The consistency of the chemical is similar to water. ... show more

  • Worth the money
The material comes in a 5 gallon bucket that is easy to open and manage. After pressure washing a couple of days before, I applied it to my driveway with a basic garden sprayer they sell at the big box stores, and then rolled it with a 3/8 inch nap roller to ensure good coverage and remove any puddles. It dries quite quickly - in about an hour in our desert climate, and once it is dry, you can't see any difference. I did two coats. Although the driveway looks the same, the results were great - water beads up and does not penetrate. This stuff is not cheapest sealer you can buy, but I got better results than I've gotten from any of the less expensive sealers they sell at the big box stores. Very happy with the results. ... show more
