Foundation Armor water repellent sealers are designed to protect concrete, brick, pavers, natural stone, and porous masonry from below the surface. They chemically react to form a hydrophobic barrier within the pores that will reduce the absorption of water and other liquids by up to 95%.  Concrete and masonry sealed with a Foundation Armor water repellent sealer will see a reduction in damage and deterioration caused by water absorption such as cracking, spalling, pitting, and the growth of mold and mildew.  Foundation Armor water repellent sealers work entirely below the surface and won’t leave a visible film or coating. The Armor SX5000 WB and Armor SX5000 are great water repellents for a natural, unsealed look and the Armor WL550 is a great water repellent if you are looking for a slight color enhancement.
