NORCROS PRO-GYP BASE ADHESIVE FOR FASTER TILING ON TO ANHYDRITE SCREEDS

Norcros Adhesives, manufacturer of tiling adhesives, grouts and surface preparation products, offers a great solution for tiling on to anhydrite (calcium sulfate) screeds.

Norcros Pro Gyp-Base Adhesive is designed for fixing tiles to the Norcros Pro Gyp-Base Fast Track Sealer. The adhesive can be applied once the sealer has dried. It is an off-white cement-based, flexible, fibre-reinforced, thin bed cementitious adhesive specially formulated for fixing fully vitrified porcelain, ceramic and natural stone tiles to the anhydrite screed sealer.

The adhesive has a setting time of three hours at 20oC, permitting early trafficking of the tiled installation. It also has excellent thermal ageing properties making it suitable for use on heated floors.

The Pro Gyp-Base Fast Track Sealer and Pro Gyp-Base Adhesive system provides a fast track tile installation system on to anhydrite screeds, without detracting from the overall screed strength and it is suitable for use on either heated or unheated anhydrite screeds.

Screeds must have reached a Relative Humidity of not greater than 95% (generally achieved 7 days after the screed has been poured) before the system is applied. The sealer system comprises a 2-part water-based resin primer, a hybrid moisture suppressant and a gritted primer. It is supplied in a 15kg kit which contains everything required to prepare and seal approximately a 25sq marea. An initial coat of primer should be allowed to dry for a minimum of two hours before a second coat is applied at right angles to the first to ensure 100% coverage. This is allowed to dry for 24 hours. The moisture suppressant and gritted primer applied to the primer coat require a total of three hours drying time before tiling can commence.
