When it comes to sealing pavers there are two types of sealers that can be used. The first type is a penetrating sealer that won't change the look or color of the pavers and the second type of sealer is an acrylic based sealer that will leave the pavers with a wet look, satin sheen, or high gloss finish.
Penetrating Paver Sealers
There are two types of penetrating sealers that can be used. The first type of penetrating sealer is a densifier and the second type of penetrating sealer is a water repellent sealer. In most cases, a densifier is not necessary. While densifiers will increase the surface strength of the pavers, they will offer no other benefits. The second type of penetratin sealer is a water repellent sealer. Water repellent sealers, like the Armor SX5000, are the best type of sealers to use on pavers if you want a sealer that won't change the look or color of the pavers, and won't leave behind a slippery surface film or coating. Water repellent sealers like the Armor SX5000, chemically react to form a hydrophobic barrier within the pores that will cause water and other liquids to bead off the surface. By reduce water absorption you can prevent a variety of issues such as cracking, spalling, pitting, ice and salt damage, and the growth of mold and mildew.
Acrylic Paver Sealers
Acrylic pavers sealers will penetrate into the pavers in order to bond. The film or coaitng left behind will give the pavers a wet look, satin sheen, or high gloss finish. Not all acrylic sealers are the same! Some coatings, like Foundation Armor acrylics, use higher quality resins and solvents in their formulations which will allow the sealer to penetrate deeper, bond better, perform better, and last longer.

Brick Paver Sealers
When it comes to concrete pavers, almost any type of sealer can be used. If however you are trying to seal red brick, you want to stick to a water repellent sealer. Red brick is made from clay and clay is very porous. Brick allows for large amounts of moisture to pass through and for that reason, virtually any type of acrylic sealer applied to brick will peel.
