Special plasticising and water-reducing acrylic admixture for heated and cooling cementitious screeds.
Available in a 10kg unit.
Mapescreed 704 is a liquid admixture made from acrylic polymers (with no formaldehyde) developed in the MAPEI Research & Development laboratories. When added at a rate of 1-1.5% in weight of the cement to a conventional screed mix (aggregates - cement - water), it improves plasticity and workability, reduces porosity and hygrometric shrinkage,
accelerates the development of mechanical strength, improves thermal conductivity and reduces drying times.
This product is very easy to use which makes it ideal for mixing screed using mechanical-computerised mixers, such as modern fixed silos or silos on trucks.
Areas of Use
For internal and external screeds on which ceramic, natural stone, parquet, resilient, carpet, etc. flooring is to be laid.
Some application examples
· Low-shrinkage screeds that must set to foot traffic in 12-24 h.
· Screeds with a high level of mechanical strength after only 7 days.
