Types of Penetrating Sealers

Under the category of penetrating selaers, there are a few different types of products:

1. Densifiers: Densifiers are typically sodium or lithium silicate based sealers. They penetrate into the surface and chemically react below the surface to form Caclium Silicate Hydrate (CSH) within the pores. Densifiers will not change the look or color of the concrete and the CSH formed is permanent. The CSH formed can't be predicted or controlled which is why multiple coats are often required. The size of the CSH structure is dependent on the posity of the concrete, the PH of the concrete during the time of application, the porosity and density of the concrete, how it was applied, and other factors. The CSH formed is microscopic and can't be seen with the human eye.

Armor S2000: Concentrated sodium silicate based sealer. Dilute with up to 3 gallons of water.

Armor L3000: Concentrated lithium silicate based sealer. Dilute with up to 3 gallons of water.

Sodium and Lithium silicates produce the same CSH structure. The difference between the two is that Lithium silicates react faster and have an easier time penetrating through dense surfaces where as the sodium silicate sealers work better in applications where moisture is present.

2. Water Repellent Sealers: Water repellent sealers are typically Silane sealers, Siloxane sealers, or Silane-Siloxane blend sealers. The benefit to going with a Silane-Siloxane blend is that you get the benefits of each type of sealer, without any of the weaknesses. Silane-Siloxane blend water repellents chemically react below the surface to form a hydrophobic barrier that repels water and other liquids. By reducing the absorption of water you prevent a variety of issues caused by water absorption including cracking, spalling, pitting, deterioration, staining, ice and salt damage, and the growth of mold and mildew. Silane-Siloxane sealers won't change the look of the concrete and they won't leave behind a surface film. Silane-Siloxane sealers are often applied after Silicate sealers to protect the concrete, and before acrylic sealers to reduce moisture movement and extend the life of the acrylic sealer.

Armor SX5000: Solvent based, high solids, Department of Transportation approved water repellent sealer for concrete, brick, stone, masonry, and tile.

Armor SX5000 WB: Water based water repellent sealer for concrete, brick, stone, masonry, and tile.

3. Acrylic Sealers: Acrylic sealers are refered to as sealers because they penetrate in order to bond. They are better classified as coaitngs however because they leave behind a noticeable surface film. Acrylic sealers are what give concrete a wet look, satin sheen, or high gloss finish.

Armor AR350: Wet look sealer designed to give substrates the appearance of being "wet". Enhances with a satin sheen finish, available in clear and color options.

Armor AR500: High gloss pure acrylic sealer designed to enhance and protect interior and exterior concrete and paver surfaces.

Armor AX25: Siloxane infused high gloss acrylic sealer designed to enhance and protect interior and exterior concrete and paver surfaces.

Armor LV25 and WB25: High gloss acrylic cure and seals designed to cure and seal interior and exterior concrete surfaces.

Tips to Consider When Purchasing a Penetrating Sealer

1. The porosity of the concrete determines how deep a sealer can penetrate, not the sealer. In a perfect world, all sealers would penetrate through an 8" slab, but that isn't the case. A typical sealer will penetrate around 1/8-1/2 inch. It could penetrate deeper than that, but it is unrealistic to expect a 4, or even 2 inch penetration.

2. Don't fall victim to false warranty claims. While the quality of the material will contribute to better performance, the actual life of the product is determined by the chemical used, how much material was applied, how and who applied the material, and the porosity of the surface.

3. Understand the chemical base before shopping out the product. In order to determine which product is better and why, you need to understand how the product works.
