Special plasticizing and water-reducing admix for cementitious screeds, including heating and cooling screeds. It is used to produce internal and external bonded, unbonded and floating screeds, including UFH, suitable for receiving ceramic tiles after only 7 days and natural stone, wood, carpet, resilient and resin flooring after 14 days.
It is a watery solution of acrylic polymers (without formaldehyde) developed in the MAPEI laboratories. When the product is added to conventional screed mixes (aggregates, cement, water) at a rate of 1.5% on the weight of the cement, it improves their plasticity and workability, reduces porosity and hygrometric shrinkage, speeds up and increases development of mechanical strength, improves thermal conductivity, reduces drying times and allows the first heating cycle to be carried out after only 15 days.
