The Polyseal Plus is a concrete sealing product manufactured by ChemMasters. The product itself is an aliphatic urethane product featuring a high solids content. This means the product performs very well, though it also dangerous and potentially harmful, for both you and the environment. Be sure to check with your state’s environmental regulations, as the Polyseal Plus features a high VOC content, which is regulated by at least sixteen different states.

The Polyseal Plus is an aliphatic urethane. Aliphatic urethanes are high quality products that are surface level sealers. The Polyseal Plus will, once applied, adhere to the surface of the concrete substrate given proper application techniques. Urethanes are extremely durable, and the Polyseal Plus offers extreme weathering and abrasion resistance, like all other urethanes, all while guaranteeing color stability and non-yellow UV protection from the sun’s potentially harmful rays. Furthermore, the Polyseal Plus can be appled to decorative concrete, as well as the stronger stuff, making it a versatile product – however, if you have a product specifically calling for a sealer that works primarily with decorative concrete, you’re better off choosing a more specified concrete sealer.

The final consideration with the Polyseal Plus is its strong odor and fumes upon application. Make sure you are in a well ventilated area when applying the Polyseal Plus, as the urethane’s fumes can be potentially hazardous to your lungs. That being said, the Polyseal Plus is no more dangerous than most other solvent-based sealers, so these are just natural and necessary precautions.
