Mapei Mapescreed 704 is a special acrylic-based plasticising and water-reducing admixture for cementitious screeds, for internal and external screeds on which ceramic, natural stone, parquet, resilient, carpet, etc. flooring is to be laid.
Suitable for:
- 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
For professional use only.

Features & Benefits
- 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
- Very easy to use which makes it ideal for mixing screed using mechanical-computerised mixers, such as modern fixed silos or silos on trucks
Preparation & Application
- 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
- Blend the cement, aggregates (0/6), water and Mapescreed 704 mix together in a mixer for around two minutes
- The mix must be applied and floated as soon as possible after mixing and within an hour from the start of preparation
- Special care must be taken on the amount of mixing water added. The mix must have a screed mortar consistency that, when tamped, becomes compact with a smooth, cohesive surface with no bleeding
- Screed mortar may be mixed with the following:
- Planetary mixer
- Standard site mixer
- Worm-screw mixer
- Mixer truck
- Automatic pressure pump
- We advise against mixing by hand; this method does not guarantee that the Mapescreed 704 is evenly dispersed throughout the mix and more water could be required to obtain the consistency required
- Before laying flooring sensitive to moisture, check the level of residual moisture in the screed with an electric or calcium carbide hygrometer
- Consumption: 1-1.5 kg every 100 kg of cement
Limitations
- Do not add Mapescreed 704 to lime or gypsum-based mortar
- Do not add to special hydraulic binders such as Mapecem or Topcem
- Protect screeds from air currents direct sunlight, freezing weather, rain, etc. for the first 24-48 hours after laying
- Protect Mapescreed 704 from frost
