Hydraulic Binder for Controlled Shrinkage Screeds from MAPEI

Special hydraulic binder for normal setting, fast drying (4 days) and controlled shrinkage screeds
Formation of bonded, unbonded and floating screeds on both existing and new concrete prior to the installation of PVC, linoleum, ceramic tiles, natural stone, carpet or timber flooring where rapid drying is required for short installation times. Suitable for indoor and outdoor use.

Some application examples:
- Formation of screeds set to light foot traffic after 12 hours and completely dry after 4 days, for laying resilient flooring and 4 days for timber flooring.
- Formation of screeds on which ceramic tiles can be installed after 24 hours and natural stone after 2 days.
- Patching and repairing floor screeds where rapid restoration is required.
- Preparation of screeds incorporating underfloor heating systems without the need for polymer additives.
Technical Characteristics
Topcem is a special hydraulic binder which, when mixed with graded aggregates and water, can produce mortars that can harden in approximately 24 hours, and dry in approximately 4 days.
Recommendations
- Do not mix Topcem with other cement, lime, gypsum or Mapecem etc.
- Do not leave Topcem dry-mixed with aggregates, immediately add the correct quantity of water to the mix.
- Do not mix Topcem just with fine sand, use aggregates graded from 0 to 8 mm (for screeds up to 5-6 cm thick).
