Polyurethane Floors

Polyurethanes sealers are nearly twice as thick as an acrylic sealer and form a high-build protective film on the concrete surface that provides excellent resistance to abrasion and chemicals. They are available in water- and solvent-based versions and a range of sheen levels. They can be used on both interior and exterior concrete to impart a transparent, non-yellowing, highly durable finish.
 
Applications
 
  • Typical applications for polyurethane sealers include:
  • Floors in high-traffic areas, to provide good resistance to scuffs and staining
  • To enhance the beauty of colored, stamped or exposed-aggregate concrete
  • Concrete countertops
  • Most polyurethanes are moisture intolerant until they cure, so they should not be applied to surfaces if any water is present. A chemical reaction will occur that results in foaming and bubbling. They also don't allow for moisture vapor to move out of the concrete, which could present problems on some exterior concrete surfaces, such as driveways.
