New concrete should be at least 14 days old. Consult Parchem for advice on the suitability of other substrates or where thickness exceeds 200 mm. Properties The values given below are average figures based on 4.5 litres of water added per 20 kg bag of Durafloor Levelbase. Actual values obtained on site may show minor variations from those quoted. Physical properties Compressive strength (70 mm cubes cured @ 23°C 40% RH): 1 day 3 days 7 days 28 days 221 Durafloor® Levelbase Floor underlay, economical sub-base build mortar (up to 200 mm thickness) Uses Durafloor Levelbase is designed as a heavy duty sub-base underlay which forms a smooth, hard surface to be used under Durafloor Leveltop and Fosroc Cemtop GP & XD where deep sections are required. Durafloor Levelbase can be used in both new construction and refurbishment projects. Advantages „ Economical „ Very fast application by pump, enables large areas of floor to be completed in a working day „ Can be applied directly onto prepared concrete floors, eliminates traditional sand cement screeds „ Dimensionally stable, can be installed in large areas „ Excellent adhesion to prepared substrates „ Rapid hardening and curing allows speedy access for overcoating with Durafloor Leveltop, Cemtop GP or XD „ One pack product, applied by pump eliminates on-site batching and ensures consistency of mixed product Description Durafloor Levelbase consists of a blend of selected cements and aggregates modified with polymers and flow agents. It is used in conjunction with Durafloor Level Prime. Durafloor Levelbase 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 by a continuous mixer pump, but can also be applied by hand. Technical Support Parchem offers a comprehensive range of high performance, high quality flooring, jointing and repair products for both new and existing floor surfaces. In addition, Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance. Design Criteria Durafloor Levelbase is designed for application thicknesses of up to 200 mm. Thicker application is possible however your local Parchem sales office should be consulted for specific advice in this situation. Durafloor Levelbase can be applied to clean, sound and well prepared concrete substrates which are free from loose material, oil, grease, paint etc. and has a minimum compressive strength of 20 MPa. November 2013 Page 1 15 MPa 20 MPa 23 MPa 30 MPa Time to foot traffic @ 23°C: 4 hours Time to overlaying @ 23°C: 24 hours* * for thicknesses up to 200 mm Maintenance If damage has occurred to Durafloor Levelbase prior to the installation of the final floor finish, repair of that area can be achieved by removing any loose material, prime the repair area with Durafloor Level Prime, allow to dry and repair with Durafloor Levelbase. Application Instructions Although Durafloor Levelbase has been designed for application by pump, the product can also be mixed and applied by hand. Preparation The substrate should be clean, sound and free from loose material and contamination such as plaster, oil, paint and grease. New concrete should be at least 14 days old. Excess laitance should be removed by light scabbling or captive shot blasting followed by vacuuming to remove dust debris. Oil and grease must be removed. Large cracks and holes may be filled using a mix consisting of equal volumes of Durafloor Levelbase and clean sharp sand made up to a trowellable mortar by the addition of a small amount of water. Prime the substrate with Durafloor Level Prime prior to repair. Priming The object of priming is to seal the substrate to prevent air release from the subfloor rising and forming bubbles and November 2013
