While this isn’t a benefit to the physical pavement, it can be useful. If you don’t believe me, try sweeping your concrete sidewalk with a push broom, then sweep a portion of the freshly seal-coated pavement with the same broom. Where the concrete tugs on the broom, the sealed pavement allows the broom to glide more easily across the surface. Colorado weather can be harsh on cars, driveways, and parking lots… Thus the cleaner and easier to clean surface that more inviting it looks to guests and potential clients.
