The Armor L3000 is designed specifically for use on unsealed concrete surfaces. It should not be applied to pavers, brick, stone, masonry, or any material other than concrete. It can’t be applied over any existing sealers or coatings.

The Armor L3000 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 L3000 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 L3000 will never break down. Calcium silicate hydrate is the same thing that forms when concrete is originally cured. The Armor L3000 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.
