The versatile screed of Anhydritec!

Screed deadlines are critical, Gyvlon can be installed at up to 200 m² per hour. After pouring, Gyvlon® Screed products can receive foot traffic from 24 to 48 hours. Drying time for a screed is approximately 1mm per day, up to 40mm. Beyond 40mm, 0.5mm per day. Under floor heating, may also be used to reduce the screed drying time. After 48 hours, the building must be properly ventilated.

Flowing screed requires fewer expansion joints than cementitious screeds. Reducing expansion joints preserves the look of the floor finish. Durability of the screed ensures the best possible surface for a final floor finish. As a free flowing and self-compacting screed, Gyvlon screed is versatile for the majority of build types and is compatible with most acoustic and thermal insulations.
