Water repellent sealers penetrate into the surface of the concrete, brick, and masonry where they chemically react to form a hydrophobic barrier within the pores. The water repellent barrier formed won’t change the look or color of the surface, and it won’t leave behind a visible surface film. Surfaces sealed with a water repellent sealer will look exactly as they did before being sealed.
There are several types of water repellent sealers, but the two best water repellent sealers are Silane-Siloxane sealers and siliconate sealers.
Best Silane-Siloxane Water Repellent Sealer
Silane-Siloxane water repellent sealers are the best type of water repellent sealer to use. They can be used to seal virtually all types of concrete and masonry including poured concrete, brick, granite, slate, flagstone, and pavers. They are easy to apply and have been used on both commercial and residential applications. Silane-Siloxane water repellent sealers are great sealers for concrete driveways, paver patios, garage floors, bridge decks, and more.

Best Siliconate Water Repellent Sealer
Siliconate water repellent sealers are cost effective water repellents because they require only one heavy coat. They are easy to apply and offer many of the same benefits Silane-Siloxane water repellents do. Siliconate sealers can not be applied to all concrete and masonry. They work best when applied to white or light gray concrete and should not be applied to dense or trowel finished concrete, brick, pavers, slate, flagstone, or stone. When applied to these types of materials they can leave behind a white crystalline residue that can be very hard, and sometimes impossible, to remove.
