Installation must not be attempted without reading the Cemtop XD Application Guide and the relevant Technical Data Sheet which give full details of the procedures for priming and application of the subsequent Cemtop XD overlay. Durafloor level prime Where Cemtop XD is being used as a wearing course, two coats of primer are recommended to ensure that the substrate is fully sealed and to minimise the likelihood of pinholes in the topping. The first primer application is carried out after the existing concrete floor has been prepared and cleaned. Durafloor Level Prime is diluted in the ratio of 1 : 5 (primer to clean water by volume). It is applied and worked into the floor by broom. The primer should not be applied by roller or spray. The second coat of primer should be diluted in the ratio of 1 : 3 (primer to clean water by volume). It should be carried out when the first coat is dry. If the floor is porous, it may be necessary to prime a third time at a ratio of 1 : 3. The primer must be well brushed into the surface. Ponding of the primer must be avoided because this can lead to failure at the bond line. The same priming procedure is adopted for both industrial and commercial applications. During application the area must be well ventilated to speed the drying of the primer. The application of Cemtop XD can proceed as soon as the second application of primer has dried. Where a dual layer Cemtop system is being applied, the base layer should be primed with Durafloor Level Prime as soon as it has hardened. Cleaning Durafloor Level Prime should be removed from tools, equipment and mixers with clean water immediately after use. Dried material can only be removed mechanically. Limitation Durafloor Level Prime is suitable for use on sound concrete and cementitious screeds that are free from surface contamination and have been well prepared. It should not be used on oil contaminated concrete or existing epoxy toppings. If Cemtop XD is to be applied over an epoxy coating, or any other substrate please contact your local Parchem sales office for advice. Durafloor Level Prime and Cemtop XD should not be applied when the surface temperature of the substrate is below 10°C, or likely to fall below 10°C within 48 hours of application. 273 Durafloor® Level Prime High performance primer for Cemtop XD, Cemtop GP, Durafloor Leveltop, Durafloor Leveltop Rapid & Durafloor Levelbase Uses Durafloor Level Prime is the recommended primer for the Cemtop XD cementitious flooring systems when applied to concrete and cementitious screeds. The primer film forms and seals the substrate to prevent air release which could otherwise cause pinholes in the floor topping. In addition it “wets” out the substrate, promotes adhesion and prevents desiccation of the Cemtop. Advantages „ Excellent adhesion to concrete and cementitious screeds „ Excellent water resistance after film formation „ Economic, easy to use with no restrictive pot life Description A water-based styrene-acrylate copolymer emulsion, formulated to achieve specific performance characteristics. It is supplied as a single component white liquid. Design criteria For the majority of applications in both the industrial and commercial sectors, two coats of primer are recommended. If the floor is extremely porous, a third coat may be necessary. Properties Typical values Specific gravity: 1.02 Solids content: 44 - 46% Drying time at 20°C: 2 - 4 hours Maximum time between coats at 20°C: 24 hours Maximum overlay time at 20°C: 8 hours Minimum application temperature: 10°C Application Instructions Durafloor Level Prime is the primer for Cemtop XD, Cemtop GP, Durafloor Leveltop, Durafloor Leveltop Rapid and Durafloor Levelbase. For specific dilution factors and application procedures regarding Durafloor Level Prime, please refer to the relevant Technical Data Sheet. Cemtop The installation of Cemtop XD is a specialist activity. It is recommended that the system be applied by a Parchem contractor who has been fully trained in the use of the November 2013 Page 1 November 2013
