Description

Anhydrite screed specially formulated to offer a strong and durable thin topping to a solid interior substrate, such as in situ concrete, beam and block or precast concrete plank. It is designed to meet class A for impact resistance and due to its ultra-thin depth it can be dried quickly, allowing rapid return to service and application of finished floor coverings.

Gypsol TS-20 thin flowing screed is perfectly suited to flooring applications where height is extremely restricted and offers a lightweight cost effective alternative to smoothing compounds. The screed is designed to be laid to a minimum depth of 20 mm and can be used either bonded directly to a solid substrate prepared in accordance with BS 8204-7 or un-bonded on a polythene membrane.
