* It is recommended to apply the first coat over a cool surface, without excessive heat, such as the morning hours. It the surface is to be continuously walked on or driven over, apply a third coat and allow to dry 72 hours. When the surface to be waterproofed is very deteriorated or has cracks the use of a perforated polyester fiber mesh is necessary with the application of the first coat while it is still humid making sure not to leave any bubbles. Allow to dry 4 hours and then continue with the process.
