  • PROFESSIONAL GRADE SILANE SILOXANE SEALER: The Armor SX5000 WB is a professional-grade water-based silane siloxane sealer designed for use on unsealed concrete, brick, paver, bluestone, flagstone, slate, natural stone, and masonry.
  • 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!
  • LONG LASTING PROTECTION: The Armor SX5000 WB Silane-Siloxane concrete sealer chemically reacts to form a water-repellent barrier below the surface that can last for up to 7-10 years. By reducing the absorption of water through the surface, damage caused by water absorption is also reduced. Sealed surfaces are more resistant to cracking, spalling, ice damage, salt damage, organic surface growth, and staining.

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.

Highly Effective Sealant, Easy to Apply
Size: 1 Gallon
I replaced an asphalt driveway with concrete at significant expense. I researched how to seal the concrete and found Foundation Armor SX5000WB. My experience with this sealant is positive. - I applied the sealant with the HDX 2 Gallon Multi-Purpose Lawn and Garden Pump Sprayer. I was going to purchase a more expensive DeWalt two gallon sprayer, but I called their support line and was told that this chemical is not recommended in their sprayer. The HDX sprayer has an apparently high failure rate per its reviews, but the unit's low cost meant that needing two of them to finish the job wasn't a significant contributor to the total cost of the project. Concrete is expensive. For the record, the HDX sprayer did the job. - I applied two coats. The instructions with the sealant say to wait 10-15 minutes between coats. The new concrete absorbed the first coat so quickly that it appeared "dry" in places within 2-4 minutes. As work progressed I shortened the interval between coats to about five minutes. This worked very well. - Coverage was about 175 square feet/gallon, in line with the manufacturer's stated coverage. - The sealant pools easily, especially the second coat. I used paper towels to dab excess away as needed. - The sealant didn't change the color of the driveway. - The performance of this sealant is simply astonishing. Prior to application of the sealant, water would be absorbed by the porous concrete, which would become very dark when wet. After application, water beads and pools on top of the sealant and the concrete barely changes color. The seal on top of the concrete is so good that in cool weather and limited sunlight, water may still be pooled on the driveway 2-3 *days* after rainfall. - The only drawback is that leaves that fall onto the wet-for-a-long-time driveway have turned into tea leaves. I have leaf prints all over the driveway. <shrug>. I can live with that. I'm going to use this stuff to seal my 70-year-old chimney. It's great. ... show more

Fantastic product!
Size: 1 Gallon
Wonderful product with clear instructions. After pressure washing my concrete patio and driveway, applied a total of 6-gallons (2 coats). I kept a 9” microfiber roller with extension on hand to manage any puddling (minimal) from the sprayer. After a day, the concrete is noticeably SEALED and fabulous to walk on and sweep and hose off dirt and debris. I have a bit of OCD when it comes to a clean outdoors and this product is worth every cent! ... show more

Good
Size: 1 Gallon
A mason friend referred this to me. I used this on two separate finishes, slate tile and engineered stone. The stone absorbed the sealer faster and I used two application as suggested. The slate however beaded as soon as I applied it, so for that I had to use a foam applicator and work it in. The next day it rained and I could see the bead on the surface of the tile. Overall I'm very pleased with it. ... show more

Great results on an interior brick wall
Size: 1 Gallon
Even though I really liked the look of my unsealed interior brick wall, it was shedding so much dust that I finally decided it was time to seal it. I happened to see the newly sealed brick walls of a renovated local business and asked them what they used to seal it because I wanted something that was a matte finish just like that. They recommended Foundation Armor SX5000WB. I picked the least humid day and the forecast predicted 3 more days with no rain so I could leave my windows open the entire time. I prepped the area with painter’s tape, plastic and drop cloths. The application process was challenging on a vertical wall (I had to use a paintbrush because of its location) and the product is very watery (and milky initially) so I started at the bottom and worked my way up. On the first coat, I wiggled the brush onto every brick and mortar line, holding a large sponge underneath to catch most of the drips that didn’t sink in; the second coat was just a quick skim over the entire wall immediately after, while it was still semi-wet. My coverage area was 85 sq ft but with both coats, I only used a bit more than half of a gallon. The result is amazing. The final color did come out slightly darker but not glossy at all. I had a few very dark obvious bricks anyway so now everything looks much more consistent and I’m getting used to it. I wore a painting respirator but honestly, when I took it off, I couldn’t smell anything (it's better to be safe though). It has only been done for a week but I can already see that I am going to have less brick dust going forward. I can definitely recommend this sealer! ... show more

GREAT product!!
Size: 1 Gallon
Price not bad either comparing to the competition but the reviews and results far better than all the others. To me worth the extra few dollars per gallon. Product was well described, perfectly described as far as application (EASY) and results. We’ll see if the seven year minimum holds up, but have no doubt we definitely buy it again Actually miss calculated what I needed so would be ordering a few more gallons this week considering what i needed (2 coats recommended) for a walkway, paver coating can’t go wrong definitely highly recommend it ... show more

Excellent product,incredible customer service.
Size: 1 Gallon
I bought the water base sealer and applied it to my concrete griffen statues.These are made from concrete but becuase of the deatil in them they are not finshed to a perfectly smooth surface as is a driveway,at first I noticed the water was absorbing into the conrete in much of the areas,leaving only some water beads.I tested the surface with water spray 24 hours after i applied it.however,if I had waited one more day,I would have seen the water beaded up more.It needed more time to dry.I did apply a coat of the solvent base sealer over the water base and this really made a difference.now its 100 % protected and water is beading up everywhere.NO water absorbtion at all now.This stuff is awesome,Customer service guys explained everything to me.I had a very porus concrete material that acted like a spong sucking this stuff up.But I think the key here is waiting at least 48 hours for it to dry and depending on your surface you have it may require an extra coat so it fills up all the tiny holes.Im sure a concrete driveway would require much less of this product becuase the surface is much smoother and finished making for much less absorbtion.a great sealer.worth the cost.the customer sercice was incredibly helpful and stood by their product in every way and were a pleasure to deal with.I will buy from them again.great choice,IM super happy,thank you ... show more

Seems to work initially - no idea on longevity at this time
Size: 1 Gallon
Bought and used 7gallons of this product. Sprayer broke so I rolled the concrete around my pool and it darkened a little bit, but looks really good. came out even in color all around. I then cleaned my front drive and sidewalk and sprayed them one coat (ran out of product - had to buy more). Rolled the 2nd coat as the first had light/dark colors - and still does even after rolling. And it didnt help that it rained immediately after I completed rolling on the 2nd coat. I hope it absorbed in anyway. My concrete is 46 years old, so I think its more porous in some places than others which may be causing the dark spots, but it really seems to be due to the spray pattern - just cant tell. I do recommend this product so far. I have no idea if it will last the 7-10 years it claims. A previous product I had used lasted around 3.5 years, but it was not a commercial grade product (eagle satin). Heres to hoping this works as advertised and keeps the concrete clean!(er) UPDATE - After hurricane Helene moved thru, left a lot of leaf debris on the driveway. I removed it after brewing in the rain for 3 days, and concrete is stained pretty badly from the leaves. Will continue to monitor, but previous brand Eagle did not allow staining at all. Will report back if stains lift over time with additional rain and sun. ... show more
