Silane-siloxane sealers are one of the most popular types of concrete sealers used to seal concrete. They are easy to apply, work entirely below the surface, and can provide years of life and protection before the need to reseal.
What is a Silane-Siloxane Sealer and How Does It Work?
Silane-Siloxane sealers chemically react to form a hydrophobic barrier within the pores of the concrete that repels water and other liquids. They work to reduce the absorption of water and liquids, therefore reducing damage and deterioration caused by water absorption. You typically can’t tell whether concrete is sealed with a silane-siloxane sealer because they don’t leave behind a visible or slippery surface film or coating. Concrete sealed with a silane-siloxane sealer will look exactly as it did before being sealed.
Why Seal Concrete With a Silane-Siloxane Sealer?
Silane-siloxane sealers are great concrete sealers because they protect the concrete without changing how it looks. Here are some of the many benefits of silane-siloxane concrete sealers:
- They reduce damage caused by water and ice
- They reduce damage caused by water resulting from the use of de-icing salts
- They reduce staining caused by water absorption
- They reduce cracking and spalling caused by freeze-thaw cycles
- They reduce mold and mildew caused by water saturation
- They are easy to apply and can last for years
What Types of Concrete Can a Silane-Siloxane Concrete Sealer Be Used On?
Silane-siloxane concrete sealers can be applied to a variety of concrete surfaces including concrete driveways, concrete pool decks, concrete patios, concrete floors, concrete walls, and more. They can also be used to seal brick, pavers, and natural stone.
What are The Best Silane-Siloxane Concrete Sealers?
With so many silane-siloxane sealers, it can be hard to choose the best silane-siloxane sealer for your concrete application. There are a few things to consider when choosing the best sealer:
- Is the sealer professional-grade? Professional grade products, and products primarily used in industrial applications, are formulated with higher quality materials and typically contain more solids.
- Does the sealer have a lot of reviews? Reviews are always a great place to look. Consider the amount of reviews, quality of reviews, and review photos.
- Does the manufacturer offer great customer support? Who you purchase the sealer from is just as important as the sealer itself. You want to make sure the manufacturer has friendly, helpful, and available support staff incase you have any questions about the product or application.
- How does the product work? The best way to see how a sealer will perform on your concrete is to purchase a small sample and apply it to a test area.
