Mapescreed 704 – Special acrylic-based admixture
Mapescreed 704 – Special acrylic-based admixture for plasticising and water-reducing admixture for use in cementitious screeds. 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.
Mapescreed 704 – Special acrylic-based admixture Uses
For internal and external screeds on which ceramic, natural stone, parquet, resilient, carpet, etc. flooring is to be laid. Any type of substrate is suitable for sand-cement screed mortar containing Mapescreed 704. To reduce the risk of rising damp, we recommend isolating the screed with sheets of polyethylene or similar material. If there is a high level of moisture, integrate the isolating system with a waterproof membrane. Existing cementitious, stone and ceramic substrates must be strong, dry and free of cracks and must have no oil stains or traces of wax, paint or gypsum.
