Installing floors over anhydrite, calcium sulphate and gypsum screeds
Anhydrite screeds, also referred to as calcium sulphate or gypsum screeds are becoming more prevalent because they provide a cost effective and eco-friendly alternative to labour intensive sand cement screeds.
UZIN produces a range of mutually compatible calcium sulphate based products such as smoothing compounds and rapid repair mortars as well as primers, adhesives and a unique damp proofing system. UZIN also have solutions to repair cracks and stress induced joints.
The entire range has been rigorously tested and used in a number of projects across the UK.
Damp proofing anhydrite screeds
Waiting for damp anhydrite screeds to dry are now a thing of the past. UZIN has developed a solution to protect calcium sulphate screeds against residual moisture up to 95 % RH. The system allows projects to be completed much quicker and avoids delays.
Crack repair systems
Floors need to be installed quickly and be available to other trades in the shortest time possible. Cracks may develop within anhydrite screeds depending on the climate and site conditions, which can cause problems and delays. Cracks and stress induced joints must be closed prior to the installation of the new floor covering. UZIN’s range of crack repair systems are ideal for remedial repairs and allows screeds to be renovated quickly and easily.
