Mapei PlaniLevel 420

PlaniLevel™ 420 is a high-compressive-strength, calcium-aluminate self-leveling underlayment designed to level, smooth and repair interior floors before installing finish floor coverings. Engineered for concrete, cement mortar beds, cement backer units, plywood/OSB and properly prepared wood subfloors, it delivers excellent flow for easy placement and a flat, durable surface. Ideal for residential, commercial, heavy-commercial and institutional projects, PlaniLevel 420 can be placed from 1/8" to 1" neat (up to 5" with aggregate) and is self-curing to reduce downtime. When used over properly primed substrates, it helps correct uneven slabs and refurbish worn interiors, providing a strong, reliable base ready for tile in as little as 24 hours and other floor coverings after proper drying.
