Norcros 20kg Pro 50 Leveling Compound
Norcros Pro 50 Levelling Compound is a single part, fibre reinforced self smoothing floor underlayment.
It is suitable for use from 3mm to 50mm in one application without the need for additional granite chippings. The product is suitable for levelling a variety of substrates including concrete, screed, flooring grade asphalt terrazzo and existing quarry and vinyl tiles. It is ideal for use with undertile heating mats where it may be used to cover the wired elements, providing a level substrate to tile to and also protecting the heating elements during the fixing process.
The product is also suitable for use on timber floors which must be overlaid with a minimum 15-18mm thick WBP or Marine-grade plywood screw fixed at maximum 300mm centres to both joists and existing boards. The plywood should be primed with neat Norcros Prime Bond which should be allowed to dry prior to application of the levelling compound.
It is essential to ensure that the floor is sufficiently rigid and deflection free to support the additional weight of tiling before commencing. The excellent levelling and flow properties of the product make it ideal for preparing sub floors prior to fixing ceramic or natural stone tiles or soft floor coverings such as carpet vinyl and timber. It has a setting time of 4 hours at 20 degrees Celsius permitting early foot traffic and fast track tile fixing.
