Mapei Topcem - Hydraulic Binder for Screeds
Fast-Setting Hydraulic Binder for Screeds Ready for Flooring in 24 Hours
Mapei Topcem is a special hydraulic binder formulated for the preparation of fast-drying, shrinkage-compensated screeds. When mixed with aggregate and water on site, Topcem produces screeds that are ready to receive flooring in as little as 24 hours (ceramics) and 4 days (resilient or wood flooring). Ideal for both bonded and unbonded screeds, Topcem is the perfect solution where time-sensitive floor installations are required in residential, commercial, or industrial settings.
Key Features & Benefits
- Rapid Drying: Allows ceramic flooring after 24 hours and wood/resilient flooring after 4 days.
- Shrinkage-Compensated: Reduces the risk of cracking and ensures dimensional stability.
- High Strength: Provides excellent mechanical resistance and surface hardness.
- On-Site Mixing: Simple to use with standard screed sand and water.
- Flexible Application: Suitable for bonded, unbonded, or floating screeds with insulation or underfloor heating systems.
