The most durable concrete sealants on the market are sodium and lithium silicate concrete sealants, such as Armor S2000 and Armor L3000 sealants. These types of sealants are designed to chemically react below the surface to form a permanent calcium silicate hydrate (CSH) barrier within the pores. Silicates last forever and will never break down. Silicate sealants react chemically beneath the concrete surface to create a calcium silicate hydrate (CSH) structure within the pores.
All silicate sealants, regardless of manufacturer, create the same CSH structure. Once fully cured, the structure of CSH can never be broken down or removed. Silane siloxane sealants last 5 to 10 years. Products in this category vary greatly from manufacturer to manufacturer.
Everything from resin quality to percentage of solids will contribute not only to the durability of a silane siloxane sealant, but also to its performance. While silane siloxane sealants can last 5 to 10 years, many store bought silane siloxane sealants will only last up to 6 months. As a polyaspartic, GP-20 has the best attributes that will benefit all types of concrete sealing projects. Provides excellent hardness and abrasion resistance.
Of all the types of concrete sealants available, this is by far the strongest sealant that can protect a concrete surface for as long as possible. However, if you are just looking for more light to medium duty concrete sealants, you have more options of the other types, such as acrylic concrete sealants, penetrating sealants, polyurethane sealants, and epoxy sealants. This concrete sealant product leaves a completely transparent and natural finish, so once you apply it, you won't even know it's there, except when water and fluids spill onto the surface and form like a freshly waxed car. Once the water thaws and contracts, the concrete tries to return to its original position and may come off.
If you don't want your concrete to look different, a clear concrete sealer that penetrates beyond the surface won't change its appearance. I put the vinyl plank flooring Home Depot Life Proof directly on the concrete because they told me I didn't need a moisture barrier. Concrete Construction noted that “when properly applied, penetrating sealants can serve as chloride screens and as moisture protection to improve the durability against destructive corrosion of embedded reinforcement and freeze-thaw damage. Salt, usually caused by rainwater in coastal areas or applied as a thawing medium, causes damage to the interior of the concrete and can discolor and crack the driveway.
It is a water-based silane and siloxane rain protector that penetrates concrete and protects it from water and moisture. Penetrates into the pores of concrete to protect it from water damage with a stable, water-resistant shield inside the concrete surface. SuperSeal25 is a semi-gloss concrete sealer that can be used for brick pavers, exposed aggregates and stamped concrete patios. In addition, Siloxa-Tek 8500 concrete sealant is more expensive than some of the other concrete sealants we reviewed, but the quality and longevity were second to none, making it a worthwhile investment.
The concrete sealant not only uses quality silanes (isoctyltriethoxysilane), it is also a well-formulated mixture of silane and siloxane. SUPER SEAL-M provides water repellency to porous building materials such as bricks, stone, concrete blocks, mortar and grout.
