Polyaspartic sealers are a relatively new phenomenon that are increasingly becoming more popular as part of epoxy floor systems. However, they are also standalone products that may be the perfect choice for your particular concrete project. While acrylic sealers are great for decorative concrete and penetrating sealers are perfect for surfaces like basement floors that need deep protection, polyaspartics are slightly different.

Polyaspartic sealers are a surface level sealer, like acrylics and epoxies. Rather than penetrate into the concrete, they will remain on the surface to be applied comprehensively to cover the concrete surfaces they are meant to protect. They tend to be solvent-based, rather than water-based, providing thorough and lasting protection.

Polyaspartics are technically a type of urethane sealers. Urethanes, such as aliphatic urethanes, tend to be one- or two-component polymers that have varying solids contents. This means they are a perfect choice for floors and other concrete surfaces with high traffic and risk of abrasions, scratches, and spills. Polyaspartics feature excellent hardness and abrasion resistance, all while repelling chemical and moisture stains.

Polyaspartics are fast becoming recognized as a miracle material. They demonstrate excellent flexibility, able to bridge small cracks and protect already cracked surfaces. Similarly, they can be applied at almost any temperature, always featuring incredible bond strength to the concrete substrate. They are long-lasting, clear, and they can easily be applied over an epoxy basecoat or a number of epoxy basecoats.

The best quality polyaspartics possess, however, is its incredibly fast tack-free dry time. Drying in as little as one hour, depending on the particular conditions of each project, polyaspartics are the best choice for retail stores, industrial warehouses, business parks, and other places whose concrete is in need of help. Simply apply the polyaspartic coating overnight, and the floor will be dry and ready to use by the morning. The high level of protection afforded by polyaspartics, in conjunction with their exceptionally fast dry time, make them an ideal choice for many concrete sealing situations.

Our Take: One of the best polyaspartics is Polyaspartic 745 with a super fast dry time of 1-3 hours
