    The substrate should be smooth, solid, clean, dry without sharp concave and convex points, honeycomb, pocking marks, peeling, free of bulges, greasy before application.

    It is better coating 2 times with scraper. When the first coat isn’t sticky, the second coat can be applied, the first layer is recommended being applied in thinner layer for better releasing gas generated during reaction. The second coat should be applied in different direction to the first coat. The optimal coating rate is 2.0kg/m² for thickness of 1.5mm.

    Attention of operation

    Wear suitable protective clothing, gloves and eye/face protection. After contact with skin, wash immediately with plenty of water and soap. In case of accident or if you feel unwell, seek medical advice immediately.
