STRATOSEY mixed with from 0 to 8 mm sand and water, turns into a mixture to be used in the construction of floating or bonded screeds on new or old slabs. When processed at a temperature of +23 °C, it gives the screeds particular characteristics: rapid hardening without undergoing appreciable shrinkage, rapid drying of the mixing water and residual humidity, high initial and final mechanical strengths that are much higher than those obtained with traditional screeds. STRATOSEY screeds must be separated from pillars and perimeter walls using, for example, expanded polystyrene or cork. Suitable for building screeds over heating systems. The use of STRATOSEY shortens the commissioning time of the system. When STRATOSEY screeds are crossed by pipes that significantly reduce their thickness, it is essential to reinforce the areas concerned with a light hexagonal wire mesh to avoid dangerous weakening of the screed. Very large surfaces must be interrupted with suitable fractioning joints. Any existing joints on the substrate must always be placed on the STRATOSEY screed.
After 8 hours the screed can be walked on; after 24 hours it is possible to lay the ceramic; after 3 days natural stones; after 5 days if the residual humidity does not exceed 2% in weight it is possible to lay wooden floors.
The residual moisture of the screed in STRATOSEY must be measured with a carbide hygrometer, which provides reliable moisture data by weight.
