Mapei PlaniLevel™ 360 is a standard-performance, calcium-aluminate-based self-leveling underlayment and repair mix for interior concrete and engineer-approved floors. It is used to level, smooth and repair floors before traditional floor coverings are installed.
It can be pumped or poured. Light foot traffic is possible after about 4 to 5 hours, depending on temperature and humidity. For deeper fills of 1" to 5", clean non-reactive pea gravel can be pre-placed or mixed in, per the data sheet.
All substrates must be primed with the appropriate Mapei primer (Primer L, Primer T or ECO Prim Grip) before the underlayment is applied.
