Sodium silicate concrete sealer for increasing the strength and density of concrete.
The Armor S2000 is a sodium silicate densifier designed to increase the strength and reduce the porosity of poured concrete surfaces. It penetrates deep into the substrate where it chemically reacts to form a calcium silicate hydrate barrier within the pores that reduces increases the strength and density of the concrete by up to 45%. It will help to reduce concrete dusting, and reduce the movement of subsurface water and moisture through the concrete.
The Armor S2000 is made from high quality, non-recycled, US manufactured resins. It is designed for unsealed concrete surfaces. It works entirely below the surface, won’t change the look or color of the substrate, and won’t leave a surface film.
The Armor S2000 is a great choice for a variety of interior and exterior concrete applications, including:
The S2000 can be applied to a variety of interior and exterior concrete surfaces, including:
The Armor S2000 is designed specifically to be used on unsealed concrete, brick, and masonry. It can’t be applied to surfaces recently applied with a water repellent sealer, or surfaces previously sealed with a film-forming sealer or coating.
The Armor S2000 is designed to work entirely below the surface. It will not change the look or color of the substrate and it will not leave a visible surface film.
The Armor S2000 is not a water repellent sealer and doesn’t offer any water repellency benefits. If you are looking for a water repellent sealer, instead consider the Armor SC25 or Armor SX5000 WB. If you are looking for a wet look, low gloss, or high gloss, consider instead the Armor WL550 for a matte wet look, the Armor AR350 for a low gloss wet look, or the Armor AR500 for a high gloss wet look.
The calcium silicate hydrate (CSH) formed from the chemical reaction between the free lime and calcium in the pores of the concrete and the S2000 will never break down. Calcium silicate hydrate is the same thing that forms when concrete is originally cured. The Armor S2000 simply takes the unreacted free lime and calcium and uses it to fill gaps in the concrete with a crystalline barrier (CSH).
The size of the barrier formed is dependent on several factors including 1) how much free lime and calcium is present in the concrete, 2) the porosity of the concrete, 3) the amount of material applied to concrete, by who and how. The size of the barrier formed will ultimately determine the actual strength and density increase.
The Armor S2000 should be applied with a HVLP pump sprayer. For best results, avoid applying with a roller. For consistent coverage, two coats should be applied back to back, while the surface is still wet.
Avoid letting the sealer puddle. If unreacted material is left on the surface, the calcium silicate hydrate will form on the surface and can only be removed through mechanical grinding.
Time of Day
To allow for proper absorption and reaction, the Armor S2000 should only be applied in the early evening (around 5 PM or later) when air and surface temperatures are declining, and when the sun is no longer positioned over the surface.
The Armor S2000 should be applied to a completely clean surface. While pressure washing the surface is typically sufficient, spot treatment may be necessary for deep or older stains. 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 S2000 to a test area to verify absorption, coverage, compatibility, and project suitability.
The Armor S2000 is designed specifically for unsealed concrete surfaces. Do not apply this product over a surface recently sealed with a water repellent sealer, or previously sealed with a film-forming sealer or coating. Do not apply the sealer to red clay brick, medium to dark gray concrete, concrete pavers, exposed aggregate concrete, natural stone or other masonry.

Porous Surfaces: up to 200 FT2 in one coat.
Smooth Surfaces (once properly prepped): up to 400 FT2 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.
