This account wanted a sealer that would be durable for exterior marble. All sealers will last 1-1.5 years. We manufacture a durable, multi-component coating that is lasting 3-4x common sealers. The durable commercial coating was used instead of sealer.
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.
