The Eagle Seal Satin Seal concrete sealer is a non-yellowing acrylic sealer that offers to provide an appropriate level of protection for all types of concrete. However, the Satin Seal is only an acrylic sealer, according to information found on its SDS sheets. Therefore, it is not an appropriate choice for any and every type of concrete; rather, it is appropriate for certain projects that require a surface-level sealer.
The Satin Seal will bond to the concrete’s surface, featuring large particles of acrylic sealant that will not penetrate past the tiny surface pores natural to all concrete. While a penetrating sealer will, of course, penetrate to chemically react within the concrete to provide protection, a surface-level sealer, like the Satin Seal, remains on the surface of the concrete to function like a raincoat. It will repel up to a certain level of water and salts, though it will not provide long-lasting protection. Similarly, the Satin Seal is really only appropriate for delicate types of concrete, such as pavers and brick, whose more porous nature render penetrating sealers ineffective.
Therefore, despite the claims of the Satin Seal concrete sealer, it is not an appropriate choice for all types of concrete. Instead of following the claims of manufacturers and distributors, make sure you do your own research online to find out the best type of concrete sealer for your particular project.
