4. Application Guide
Surface preparation
Thoroughly clean the substrate surface, removing oil and rust. Blast steel to Sa2½ (ISO 8501-1), surface profile 40-75 μm. Concrete substrate moisture content<6%，Sanding去除浮浆。Old coating需清除松脱部分并拉毛deal with.
Mixing / compounding
According to the mix ratio indicated on the product label, add the hardener (component B) slowly to the base (component A) and mechanically stir for 3-5 minutes until uniform. Let stand to mature for 10-15 minutes before use. Use up within the specified pot life after mixing.
Application method
Recommended air spray (gun orifice 1.5-2.0 mm, pressure 0.4-0.6 MPa) or airless spray (nozzle 0.38-0.53 mm, pressure 15-25 MPa). Small areas may be brushed or rolled. Keep each coat dry film thickness within the specified range.
Curing Conditions
Self-curing at room temperature (23°C), with relative humidity meeting requirements. Low temperature (<5°C)或高湿(>Construction is prohibited under conditions of 85% (humidity). Performance testing shall be conducted after complete curing.
