The product can be used for the reinstatement of existing floors or as a final wearing course on new concrete floors where specified floor tolerances have not been achieved or where, for speed of installation, the concrete floor has been left with a rough screed finish. It is suitable for use across a wide range of industrial environments such as warehouses, light to medium engineering operations, food processing plants, car parks etc. It may be used either as a stand-alone system, or depending upon the end use of the floor, in conjunction with the Nitoflor and Durafloor range of resin based floor coatings. Advantages „ Very fast application and rapid cure - minimises factory downtime „ Economic - more cost effective than equivalent resin based systems „ Dimensionally stable - can be installed in large jointless areas „ Self smoothing - minimal finishing required „ Durable - smooth dense surface, resistant to forklift truck traffic „ Water vapour permeable - allows installation on floors subject to rising damp „ One pack product, applied by pump - eliminates on-site batching and ensures consistency of mixed product Technical Support Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance. Standards Compliance Cemtop XD complies with the requirements for a Class O surface, as defined in paragraph A8 (b) of Approved Document B, ‘Fire’, to the Building Regulations 1985. BS 476: Part 6: 1989 ‘Method of Test for Fire Propagation for Products’ - Fire Propagation Index, I=2.0. BS 476: Part 7: 1987 ‘Surface Spread of Flame Test for Materials’ - Class 1 Surface Spread of Flame. Description Cemtop XD cement based floor surfacing system consists of a blend of selected cements and hard wearing aggregates modified with polymers and flow agents. It is used in conjunction with Durafloor Level Prime, a water based styrene-acrylate copolymer primer. It is supplied as a grey powder which requires only the addition of water to produce a self smoothing, free flowing material. The product is designed for installation using a continuous mixer pump or mixing by hand. Design Criteria Cemtop XD is designed for application at a minimum thickness of 6 mm. It can be applied onto a clean, sound and well prepared concrete floor which is free from loose material, oil, grease, paint etc and has either a minimum 25 MPa compressive strength or a surface tensile strength value in excess of 1.25 MPa. If the strength of the concrete floor is below these values please contact your local Parchem branch for advice. Where thicknesses of Cemtop XD in excess of 12 mm are required it is recommended that Cemtop GP underlayment is used as a base layer, at a minimum thickness of 7 mm beneath the Cemtop XD. When Cemtop XD is being used as a single layer, standalone system the concrete must be sufficiently dry to allow absorption of the primer. If the product is being overcoated with an impermeable topping, such as an epoxy screed, the relative humidity of the concrete floor must not be greater than 75% at the time of installation. The relative humidity must not be greater than 80% if a Nitoflor resin based coating is being applied. New concrete should be at least 14 days old. Please consult Parchem for advice on the suitability of other floor surfaces. January 2008
