WHAT’S NEW?
Norcros Adhesives fills us in on the company’s latest news, introducing recent product launches and a new state-of-the-art website.
Norcros Adhesives, the manufacturer of tiling adhesives, grouts and surface preparation products, is launching a number of new products which will be of interest to the contract flooring sector. It is also introducing a new website which uses state-of-the-art web design and integrates with the company’s increasingly important social media channels.
A key new product for the sector is Pro Gyp-Base Fast Track Sealer, which greatly reduces the minimum drying times normally applicable for anhydrite (calcium sulfate) screeds. The new product comprises a three-stage preparation system for fixing ceramic and porcelain tiles on to screeded surfaces. It is sold as a kit containing all the elements necessary to achieve a successful bond, including a primer, moisture suppressant and gritted primer.
Used together, the system allows for fast-track tile installation without detracting from the overall screed strength. It also avoids the need for a special tile to gypsum adhesive, which is normally required for tiling on to anhydrite screeds to prevent the tiles from debonding.
Pro Gyp-Base Fast Track Sealer can be used on either heated or unheated anhydrite screeds. A 15kg kit contains everything required to prepare and seal an area covering approximately 25 square metres. In an ambient temperature of 20o
C, drying times are down to two hours for the first
primer coat and 24 hours for the second primer coat. The moisture suppressant and gritted primer require a total of three hours drying time before tiling commences. Screeds need to be a minimum of seven days old and have a maximum relative humidity of 95%.
After drying, tiles may be fixed with the new Norcros Pro Gyp-Base Adhesive. This is a white cement-based, flexible, fibre-reinforced, thin bed cementitious adhesive specially formulated for fixing fully vitrified porcelain, ceramic and stone tiles to Norcros Pro Gyp-Base Fast Track Anhydrite Screed Sealer. It has a setting time of three hours at 20o
C
permitting early trafficking of the tiled installation. The adhesive has excellent thermal ageing properties making it suitable for use on heated floors. It is sold in a 20kg pack.
“This new system from Norcros Adhesives is designed to tackle one of the key issues associated with the increasingly popular anhydrite screeds, namely extended drying times, which can be up to 80 days for a 60mm screed,” says Mandy Searle, technical services at Norcros Adhesives. “This new system solution should prove a real benefit on-site for flooring contractors and tile fixers.”

Meanwhile, on the grouts side of the business, the company is relaunching its successful 4 into 1 range with new improved formulations, new colours, new packaging and marketing support.
In recent years the Norcros 4 into 1 Grouts and Sealants range has become established as one of the leading ranges on the market, known for technical excellence and ease of use.
The new range has been considerably expanded and now includes a total of 15 colours. The products have been reformulated to be efflorescence-resistant and water- repellant. Efflorescence is the movement of salts within a porous material, including tiles and grout, to the surface of the material where it can leave an unsightly deposit. In some tiling installations it can be a real problem which negatively affects the aesthetic appearance of a tiled surface.
The formulation of the new grouts contains Norcros Stop Mould Antibacterial additives to protect against mould and discolouration, which can occur when wet areas are grouted.
