Technical Leaflet after 24 h at 23°C after 7 days at +23°C > 3 N/mm2 (breaking point of concrete) cleaned with water Description EPOXYPRIMER-500 is a two-component, water-based epoxy system. It provides high hardness and abrasion resistance. It can be applied on dry or slightly damp substrates, without standing water. It is classified as SR-B2,0 according to EN 13813. EPOXYPRIMER-500 is used as a primer of ISOFLEX-PU 500 and other polyurethane systems, when applied on non-absorptive substrates or old waterproofing layers. It may also be used as a primer, as well as for preparing (with the addition of quartz sand) a repairing (filling) material for cement-based substrates, such as concrete or cement-screeds, that will be covered with DUROFLOOR epoxy resins. Successive layer: Final strength: Adhesion: Cleaning of tools: Tools should be immediately after use. 1. Substrate preparation The substrates to be coated should be: • Stable. • Free of materials that prevent bonding, e.g. dust, loose particles, grease etc. • Protected from underneath moisture attack. In case of applying epoxy resins of DUROFLOOR system, they should meet the following requirements: Concrete quality: at least C20/25 Cement screed quality: cement content Basis: Color: Viscosity (A): Viscosity (B): Viscosity (A+B): Density (A): Density (B): Density (A+B): Mixing ratio (A:B): Pot Life: Minimum hardening temperature: Walkability: In addition, substrates should be prepared by brushing, grinding, milling, sand blasting, water blasting, shot blasting etc., depending on their nature. Then, the surface should be well cleaned from dust with a high-suction vacuum cleaner. 2. Mixing of the components Components A (resin) and B (hardener) are packed in two separate containers, having the correct predetermined mixing ratio by weight. The whole quantity of component B is added into component A. The two components should be mixed for about 2-3 minutes with a low-speed mixer (300 rpm), until the mixture becomes uniform. It is important to stir the mixture thoroughly near the sides and bottom of the container, to achieve uniform dispersion of the hardener. The addition of water (1030% by weight) will then ensure that the mixture obtains the desired workability.

3. Application-Consumption Depending on the application, EPOXYPRIMER-500 may be used in the following ways: a) As a primer of ISOFLEX-PU 500 The substrate is primed with EPOXYPRIMER-500, thinned with water up to 30% by weight. The product is applied by brush or roller in one coat. Consumption: 150-200 g/m2. Depending on the weather conditions, IsOfLEX-PU 500 is applied within 24-48 hours from priming, as soon as the moisture content falls below 4%. b) As a primer of epoxy resins The substrate is primed with EPOXYPRIMER-500, thinned with water up to 30% by weight. The product is applied by...
