GENERAL INFORMATION

Düraamen Epoxy, Polyurethane and Polyaspartic coatings are high performance coating systems that provide protection against dirt and chemical penetration to concrete floors. They are available in various performance levels. Contact your Düraamen Representative for assistance with proper material choice for specific performance criteria.

SURFACE PREPARATION

Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared as outlined in Düraamen’s TECHNICAL BULLETIN #1. Specific attention should be paid to the following:

• Concrete placement
• Curing and finishing techniques of the concrete substrate
• Age of concrete
• Previous contamination of the substrate
• Present condition of the substrate
• Surface profile required for the system (ICRI CSP 2-5 is typical, varies by system)

Also, the temperature and humidity conditions of the area to receive the flooring system should be checked. An optimum room temperature of 75°F with a minimum slab temperature of 50°F is required for proper cure of the resin flooring system.

Installation over existing resin coatings: The existing resin flooring or coating must have acceptable adhesion to the substrate and have similar physical properties to the new coating (e.g., epoxy over epoxy, urethane over epoxy/urethane, acrylic over acrylic, etc.). The hardness and physical condition of the existing coating will dictate the required surface preparation. Harder resins will require more extensive sanding or may require diamond grinding. The surface must be thoroughly cleaned of any dirt, oil or other contaminates, followed with aggressive sanding/grinding using 60-80 mesh sand paper, abrasive screen or diamonds. Vacuum and damp mop any dust. The goal is to impart a textured profile in the existing coating or floor system to provide a mechanical bond for the new resin application. Cracks and divots should be routed or chipped out and filled with epoxy resin. Acrylic coatings on exterior decks applied to a textured surface can not be sanded without removing the texture, pressure washing and solvent wiping may be the only viable option. The intercoat adhesion of acrylic coatings is not ideal even with sanding, which will dictate that more frequent reapplications be done in the future. Once every year or two is typical.
