Epoxy primer; It is a primer system developed for use on interior and exterior surfaces, concrete and cement-based mineral surfaces and highly absorbent floors. It can be applied as a primer for Kenncoat brand epoxy, polyurethane, acrylic and polyurea floor coverings, and can be used in combining epoxy-based leveling mortars and mortar coatings. It also acts as aggregate or repair mortar and increases adhesion on metal surfaces.

Before starting the mixing process, ensure that product temperatures are between + 15⁰C and + 25⁰C. Before mixing, mix components A and B with a mechanical mixer at a very low speed. Gradually add component B to component A and mix until a homogeneous consistency is reached (About 3-5 minutes). If used as repair mortar, add aggregate after mixing components A and B. Pour into a clean, dry container and stir for a few more minutes. Avoid high speed mixing and do not add any solvents, thinners to the mixture during the application procedure.
Avoid application under extreme heat, sun, wind, rain, when the surface temperature is below + 10⁰C or above + 30⁰C. In extremely cold conditions, heaters should be used to increase the workability of the environment and the product.
After mixing, primer; It can be applied to the surface using a brush, roller, trowel or squeegee. Make sure a continuous, non-porous coating covers the substrate. Apply two coats if necessary. In order to increase the adhesion of the epoxy or PU layer to be coated on the surface, aggregate (200-500 micron thickness) can be applied by mixing it into the primer or by sprinkling it after being applied to the surface. The mixed product should be applied within 20-30 minutes. The waiting time between coats must be at least 10 hours and at most 48 hours at +20 ° C. If waited for more than 48 hours, the surface should be sanded. The product must be left to dry completely for at least 7 days to reach its maximum mechanical and chemical resistance. Reaction times are prolonged at lower temperatures, increasing pot life, coating interval and working time. High temperatures increase chemical reactions and the time mentioned above decreases accordingly. After application, the material should be protected from direct contact with water for at least 24 hours. Contact with water during this period may result in a carbonated surface and/or surface stickiness that must be removed. In such cases, the general coating must be removed from the floor and renewed. Epoxy and polyurethane floor systems should be installed by experts.
Cleaning of the equipment used should be done with organic solvents such as thinner and butyl acetate.
