What is the best method for damp proofing anhydrite screeds?
With UZIN PE 425.
The industry has seen a growth in the use of anhydrite screeds (also known as calcium sulphate or gypsum screeds) but there has always been a problem with adequately protecting against residual moisture, especially if the relative humidity is above 85%. UZIN has developed a solution for damp proofing anhydrite screeds for residual moisture up to 95% RH. With UZIN PE 425 projects can be expedited without the long delays previously caused by damp anhydrite screeds.
