Review: Outstanding protection - This product is incredible. In florida I have to power wash the concrete walkways 2-3 times a year to remove the algae, fungus and other fauna that grows in the wet humid conditions. This year i applied the Armor product in April and the concrete looks like I just power washed it. I was easy to use, keeps the water from penetrating and the fauna from growing. It is expensive but very effective and I will be applying to more concrete next spring.
Review: Highly Effective Sealant, Easy to Apply - 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. . I can live with that. I'm going to use this stuff to seal my 70-year-old chimney. It's great.

## Features

- 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%.
- WON’T 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.
- READY TO USE: The Armor SX5000 WB is ready-to-use and can be applied to a properly cleaned and prepped unsealed surface with pump sprayer. One gallon covers up to 175-225 square feet per gallon. Foundation Armor cleaners and sprayers are available separately.
- EASY TO MAINTAIN: The Armor SX5000 WB works entirely below the surface so there is no surface film or coating to maintain. When it is time to reseal, simply apply 1-2 coats of the Armor SX5000 WB to a clean, dry, and absorbent surface with a pump sprayer.
- WATER BASED FORMULA: The Armor SX5000 WB is water-based. It is easy to use, 0 VOC, and has no odor. Clean-up is quick and easy, and can be done with soap and water.

## Questions & Answers

**Q: Can you use the water based product on a chimney that had been previously  treated with  a solvent based siloxane treatment?**
A: Great question, as long as the previously sealed surface is capable of absorbing water it will soak in the SX5000WB(might not take as much sealer for a touch-up job).

**Q: Can I apply a second coat a week after the first coat?**
A: I applied my second coat about 2 weeks after the first coat. The outcome was the same as expected as if the second coat was applied as directed. I did notice that in between the first and second coats, I observed areas not 100% sealed on my surface. However, this was completely rectified following the application of the second coat. After several downpours, my deck has remained completely sealed.

**Q: How effective for sealing existing exterior concrete walls showing signs of water damage.**
A: Very effective. Used it on my brick chimney. Rain and snow seemed to slide right off with no absorbtion. Goes on clear so you can not see it.

**Q: It rained unexpectedly hours after applied and concrete lools discolored.  Will it dry normal or stay discolored? How can we fix?**
A: Give the surface several days to a week and re-evaluate to see if appearance improves.  It's possible that the rain caused some of the active ingredients to migrate/build in certain areas.  If the surface doesn't improve, please call Foundation Armor tech support M-F EST 9am to 5pm for assistance. There are sodium hydroxide cleaners capable of removing surface deposits(dark spots) if needed.

### ⭐⭐⭐⭐ Sealing stone entrance
*by J***. on June 20, 2023*

Bought Armor SX5000 WB to seal the stone floor and wall of my front entrance. Water base is easy to apply and no harmful smell. Soaks in very quickly and you need to apply the second coat immediately so it too will penetrate. Results: No change of stone color, good beading waterproofing. Good product.
