Armor S2000 Sodium Silicate Concrete Densifier and Surface Hardener - 1 Gallon - Ready to Use

Seals deeply and strengthens as well as protects your concrete. This product is great for garage floors because it seals them permanently against oil, salt, and other concrete damaging agents. It applies easily with a sprayer after mixing with hot water. This is NOT a cosmetic surface sealing agent, it penetrates up to 4" deep binding to any calcium and silicates to reduce water absorption up to 98%, giving high resistance to efflorescence, yielding a 45% increase in compressive strength, a 45 % increase in surface hardness, and finally, a >200% increase in wear resistance! We sealed our 1350 sq foot concrete slab barn floor with 1 gallon of Foundation Armor S2000 mixed with 3 gallons of hot water, using a garden sprayer and a long handled brush to spread any puddled or over-sprayed areas.

This is my second time using the product. In both cases the before and after are the same story. Before we had signs of efflorescence and concrete shedding from basement walls. The product is easy to apply with a spray and goes on evenly. After it dried the shedding was gone. Three years later and no occurrence of efflorescene and no more shedding. Just applied it at another location and expecting the same results there,

Easy application with foam paint brush roller. It does leave a slight wet look as shown in the photo. This does not bother me but may not be desirable to others. I plan to use their sealant next.

Went on very easy with a paint roller. After letting it sit for two days I see no difference but now I have a white powdery floor.

Applied per instructions. Product is superb. The product lays down perfectly. Two this coats were applied. Without hesitation I would buy again. I am planning to using Armor products for all our concrete applications. Finally, someone makes these products in one gallon containers!! Kudo to the Armor folks! I’m sick of only buying five gallon containers.

I thought I was getting a dilutable product that would make 4 gallons. What I recived was one gallon undilutable which was not enough to do my project. I have foung another product that will work. They also have the same picture indicating 4 gallons on Home Depot's page so I don't think this is a complete accident.

I wish I had a picture of my 1000sqft floor before I applied this product because I'd sue them. I grinded my floor (spent thousands with grinder rental) and it looked gorgeous, ready for a densifier. Followed the instructions. This product destroyed my floor.

I spoke with tech support before ordered this and explained our dusting problem (it was excessive). He explained how to prep the surface properly and then apply to liquid. It bubbled upon contact, and the dust was noticeably less after 1 day (70% improvement). Our concrete had cured exceptionally poorly, and he suggested we might need a second treatment. The difference was so noticeable on the first treatment, that we did a second floor prep and will do second treatment. During the second floor prep, the floor was significantly less absorbent to water. Please note, this does not correct any surface imperfections from poor application of concrete. It does definitely harden the surface.
