TYPICAL DRY FILM THICKNESS
Variable, although generally a film of NPA exterior coating is about 20 times the thickness of a normal paint film.

The NPA system is so thick and substantial that it can take up to 2 to 3 weeks to fully cure and dry. Customers must avoid placing ladders or any other objects onto the wall surface during this time.
