Best Silane/Siloxane Sealers

Best Silane Siloxane Concrete Sealers

While all Silane/Siloxane sealers contain both silane sealer and siloxane sealer, they couldn’t differ more when it comes to formula, life, and performance. The reason Silane/Siloxane sealers differ so much from one manufacturer to the next is that they all contain a different level of active materials.

You can usually tell how much active materials a Silane/Siloxane sealer contains by reading the SDS sheet or the Technical Data Sheet. You will find that most in-store sealers contain only 2-8% solids and sell for around $150 or less, and most online or pro-grade sealers contain 20-40% solids and sell for $250 or less. Pro-grade brands contain up to 20X more active materials than most in-store Silane-Siloxane sealers. This difference is evident in life and performance. In-store Silane-Siloxane sealers need to be resealed every 1-2 years, while pro-grade sealers need to be resealed every 7-10 years.

Frequently asked questions about Silane Siloxane Sealers:

  1. Are water based Silane-siloxane sealers better than solvent based Silane-Siloxane sealers? One isn’t necessarily better than the other. Water based Silane-Siloxane sealers have a larger molecule and solvent based have a smaller so water based are commonly used on porous brick or masonry surfaces.
  2. Why not apply a 100% solids solution? Most silane-siloxane sealers don’t go over 40% solids because when you go higher than 40% solids, especially on a residential application, you can run into issues with dark spots on the concrete.
  3. Should I use a roller or sprayer? You will get better coverage with a sprayer than you will with a roller, but rollers can be used.
  4. What you can you seal with a Silane-Siloxane sealer? You can seal concrete, brick, pavers, granite, stone, stucco, and porous masonry.
  5. How is a silane-siloxane sealer different from a silane sealer or a siloxane sealer alone? Silane sealers work better below the surface, siloxane sealers work better on the surface, and silane-siloxane sealers work better above AND below the surface.
