Surface preparation before  treatment

The surface to be primed must be dry, free of rust, moss, oils and other dirt. To remove peeling paint and rust from previously painted surfaces, sandblasting (to a degree no less than Sa² according to ISO 8501-1) or manual cleaning with a steel brush or sandpaper is recommended. OPS Pro can be used to remove old paint. Be sure to wash the cleaned surface with Katto Cleaner before priming, then rinse with water and allow to dry.


Mix well before use. Apply 1 coat of paint with a brush or a spray. Use a nozzle size 0.015 - 0.019 inch when working with a high pressure spray. When spraying, add 5-10% of water to paint. The temperature of the surface to be painted must not be below +10° С and above +40° С. The relative humidity must be below 80%. The painting work should be timed so that the treated surface can dry before the evening dew appears. It is not advisable to work in hot weather, direct sunlight, too cold weather, rain, fog. Please follow the instructions for use of the above products.
