The concrete floor’s durability is a primary concern in any structural development, including the pool deck and basement floor. This is especially true if your concrete driveway or patio is aging – maybe you’ve tried painting?
The best concrete sealers are designed to protect the surface floor from corrosion, physical damage, and surface staining. Exposing the concrete to various elements and hard wear may cause faster wear.
But with the best penetrating concrete sealer, you can easily enhance, protect, and seal the concrete surfaces. So, I’ve reviewed the editor’s top penetrating concrete sealer based on water absorption, quality, and durability.
Reviews: 7 Best Penetrating Concrete Sealer in 2020
SX5000 is a water-based breathable silane-siloxane high penetrating sealer used on the unsealed surface, both interior and exterior surfaces – with low VOCs.
The sealer is highly formulated to chemically react and form a water-proof barrier, reducing water penetration up to 95%. The transport department approves it as a concrete sealer and suitable for roads and bridges to reduce water absorption damage.
The SX5000 is suitable on bricks, horizontal surfaces, masonry concrete, and seals without changing the surface’s looks. It is non-slippery and does not change the color or the face of the surface applied on.
The sealer contains active ingredients five times more than similar products in the market and can be applied either using a roller or a sprayer.
SX5000 is breathable and works under the surface while still maintaining the old natural look of the surface.
It is manufactured with non-recycled resins and is durable, lasting up to 10 years on the surface. There are four common kinds of concrete sealers; these are acrylics, penetrating sealers, polyurethanes, & epoxies – with many subtypes as well.
