Mapescreed 704 - Special acrylic-based plasticising and water-reducing admixture for cementitious screeds
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.
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.
