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. Review: Quick, simple and effective - 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, ## Features - PROFESSIONAL GRADE SODIUM SILICATE SEALER: The Armor S2000 chemically reacts with the free lime and calcium in the concrete to form a permanent Calcium Silicate Hydrate crystalline structure within the pores. - INCREASES STRENGTH UP TO 45%: The CSH crystals formed during the chemical reaction will help to increase the strength of concrete by up to 45%. - REDUCES DUSTING AND DETERIORATION: The increased strength and density gained by the formation of the CSH crystals in the pores will help to reduce dusting and deterioration caused by surface abrasion. - WON’T CHANGE THE LOOK OR COLOR: The Armor S2000 works entirely below the surface and won’t leave behind a visible film or coating. The concrete will look and feel natural. - LONG LASTING: The CSH crystals left in the pores of the concrete are permanent and can only be removed by means of mechanical grinding. - READY TO USE: The Armor S2000 is ready to use. Simply add to a sprayer and apply! One gallon covers up to 200 square feet per gallon. Smooth, absorbent surfaces can get up to 400 square feet per gallon. - EASY TO MAINTAIN: There is no maintenance with the Armor S2000. Once applied, you don’t need to apply it again unless you desire an even stronger surface. - VERSATILE: The Armor S2000 is great for use on existing concrete. It is also used by many concrete professionals on new concrete pours to help increase the strength and density during the curing process. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007NMK7II | | Best Sellers Rank | #96,505 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #47 in Concrete | | Brand | Foundation Armor | | Brand Name | Foundation Armor | | Color | Clear | | Compatible Material | Concrete | | Customer Reviews | 4.0 out of 5 stars 49 Reviews | | Included Components | Concrete Densifier and Surface Hardener | | Item Form | Liquid | | Item Weight | 9 pounds | | Manufacturer | Foundation Armor | | Material | Silicate | | Material Type | Silicate | | Model | S2000 - 1 Gallon Ready to Use | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 1M-D7A7-3ECP | | Style | S2000 | | Style Name | S2000 | | Surface Recommendation | Concrete | | UPC | 610370080221 | | Unit Count | 128 Fluid Ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Foundation Armor - **Item Weight:** 9 pounds - **Material:** Silicate - **Style:** S2000 - **Water Resistance Level:** Water Resistant ## Images ![Armor S2000 Sodium Silicate Concrete Densifier and Surface Hardener - 1 Gallon - Ready to Use - Image 1](https://m.media-amazon.com/images/I/71gkdWcyfdL.jpg) ![Armor S2000 Sodium Silicate Concrete Densifier and Surface Hardener - 1 Gallon - Ready to Use - Image 2](https://m.media-amazon.com/images/I/81-w+I0YT1L.jpg) ![Armor S2000 Sodium Silicate Concrete Densifier and Surface Hardener - 1 Gallon - Ready to Use - Image 3](https://m.media-amazon.com/images/I/810F5yRTziL.jpg) ![Armor S2000 Sodium Silicate Concrete Densifier and Surface Hardener - 1 Gallon - Ready to Use - Image 4](https://m.media-amazon.com/images/I/81Lwi--2J1L.jpg) ![Armor S2000 Sodium Silicate Concrete Densifier and Surface Hardener - 1 Gallon - Ready to Use - Image 5](https://m.media-amazon.com/images/I/91Y6zpOS-IL.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: should i use this first then water proof or vice versa?thank you** A: The S2000 should be used on unsealed/porous concrete at least 5 days prior to applying a water repellent product. **Q: I want to re-seal my driveway 25 x 75 pavers are 1 inch thick on top of a sand base. Will this product work?** A: The Armor S2000 should not be applied to previously sealed pavers or colored concrete. **Q: My 1 year old driveway has been dusting since the day it was poured (maybe due to heavy rain). Will this reduce dusting? This is my only need, thanks.** A: The S2000 hardens healthy concrete and usually helps reduce dusting but may not stop it completely. If the S2000 is used and dusting continues, consider an acrylic coating that can physically form a hard/thin surface film for additional abrasion resistance. **Q: What sorts of precautions do I need to take when handling / applying this? For my safety.** A: Wear goggles and a mask if you are spraying and wind will be a factor (blowing back at you). If the product contacts your skin wash off with soap and water. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Penetrating hardener, sealer, and bonding agent for all concrete surfaces. *by A***N on December 7, 2013* Seals deeply and strengthens as well as protects your concrete.

It does leave a slight wet look as shown in the photo. This does not bother me but may not be desirable to others.
