National Sealing Co is the largest paver sealing company in the US with well over 2M square feet protected. In addition to offering common paver sealer, National Sealing offers a durable coating process. Typical paver sealers will last 1-1.5 years. Our durable coating process will last between 3-5 years. Our process is a multi-component process which is mixed on site. This coating hardens and forms a durable barrier and is much more resistant to harmful UV rays than common paver sealer.
In addition, we have developed a dyeing process to restore faded pavers. This process can be seen on our site as well as You Tube.
