Mapei PlaniLevel™ 450 is a calcium-aluminate-based, quick-setting, self-drying self-leveling underlayment and repair mix for interior concrete and engineer-approved floors. It has high compressive strength and is abrasion-resistant.
It can be installed from 1/16" to 1-1/2" and withstands light foot traffic after 2 to 3 hours and rubber-wheel vehicle traffic after 3 days. It must be covered with a finished floor system; it is not a wear surface.
All substrates must be primed with the appropriate Mapei primer before the underlayment is applied.
