68 Selection of the appropriate binding resin for each application Depending on the application (interior or exterior, floors or wall, etc.), there is the appropriate binding resin with which the QUARTZ DECO aggregates are mixed, in order to create the decorative coating. Interior application on floors and steps, as well as their application in bathrooms, showers, and swimming pools, use the epoxy binding resin QUARTZ DECO EPOXY. Exterior application on floors and steps use the polyurethane binding resin QUARTZ DECO PU. Application on walls on interior and exterior surfaces, mix them with the hybrid binding resin QUARTZ DECO HYBRID. For additional information, consult the relevant technical brochures that you will find at www.durostick.com The Substrate, Inspection, and Preparation The careful preparation of the substrate for the stone carpet and granite plaster systems, as well as other linings proposed for application, is crucial for the final result. All application surfaces must be sound, free from loose materials, dust, grease, oils, and they also must be completely dry. In addition, it is essential that the floor substrate is flat and structurally adequate. The moisture content of the substrate should not exceed 5% and the relative humidity in the application area should be less than 65%. The application of the mixture is done on properly prepared surfaces, according to the instructions on the binding resin that is suitable for each application. Surface preparation before the application on floors, stairs, and swimming pools. If the application is related to a floor surface that is not perfectly flat and must be evened to a thickness of 1-2cm, the application of the flexible, quick-setting, cementitious adhesive (C2TE/S1) DUROFAST FLEX of DUROSTICK is recommended. If leveling is required in larger thicknesses than 2-5cm, first prime the substrate with the acrylic emulsion D-20 of DUROSTICK, and then use the fiber-reinforced cement mortar D-6 of DUROSTICK. It is important to apply the cement screed while the emulsion is fresh, in order for it to act as a bonding bridge. For exterior applications, first waterproof the substrate with the brushable, cementitious waterproofer D-1 or D-1 FLEX of DUROSTICK. The above-mentioned, treated surfaces, as well as surfaces made of tiles, marble, mosaic, etc. are finally prepared with the epoxy primer WATERPROOF EPOXY PRIMER AQUA. The application of the quartz mixture follows up to 12 hours after the application of the primer. QUARTZ AGGREGATES APPLICATION GUIDE
