The two most common types of concrete floor sealers are silicate based sealers and silane-siloxane water repellent sealers. Each type of sealer functions very differently from the other.

Concrete Floor Sealer: Silicates

Silicate based concrete floor sealers are sodium or lithium silicate based sealers densigned to increase the strength and density of concrete floors. They are very popular sealers because they are inexpensive to purchase and very easy to use. Silicate sealers are designed to increase the strength and density of the concrete. That is their primary use and should be their primary purpose. They chemically react to form a microscopic crystalline barrier within the pores. Silicate based sealers will help to reduce dusting, and through densification can reduce seepage, but other than that, silicates are  not designed to offer any additional performance benefits. If you want to water to bead off the surface you need a silane-siloxane water repellent, if you want a wet look or high gloss then you need a coating.

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

Concrete Floor Sealer: Silane-Siloxane

Silane-Siloxane water repellents reduce the absorption of water and other liquids, preventing a variety of issues including cracking, spalling, pitting, dusting, staining, ice and salt damage, and the growth of mold and mildew. They can be applied directly to the bare concrete surface, or to surfaces previously sealed with a silicate densifier. They are slightly more than a silicate based densifier, but they offer more benefits. Silane-Siloxane sealers can also help to reduce moisture movement through a concrete slab.

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

Concrete Floor Sealer: Concrete Coatings

If you want a wet look, satin sheen, or high gloss finish you want a concrete coating, not a concrete sealer. Coatings can enhance, or cover, a concrete floor and leave behind a decorative finish.
