2. Painted Surface 

Ensure the condition of the painted surface is free from defect, dry, clean and free from contaminants. Repair any defect and repaint the surface with suitable paint if required. Leave it to dry for at least 24 hours. Ensure the paint and the color is in good condition before applying Rainbow White Board Paint.

Application Method: Polyester Brush / High Density Foam Roller / Conventional Spray or Airless Spray。
For DIY Users, we recommend to apply using high density foam roller, also known as dense foam paint roller. Mix the Base and Hardener at the ratio of 4:1, Stir Well. Apply the mixture smoothly onto the Paint coating and leave to dry. Use roller tray or paint pan to prevent under-loading or over-loading of roller. We suggest interval application of the coating in vertical, then horizontal direction to reduce streak, drips and lap marks. Repeat the application direction when more coat is required. Successive coat can be apply after 2 hours, if re-application is after 5 days, we suggest to sand the surface with 400 sand paper before application to scuff the surface in order to increase adhesive. At least two coats is required for better result. If you want the smoothest finish possible, then wait until the first coat is dry (around 2 hours), very lightly sand with very fine sand paper (Suggest using 400 – 800 sand paper) to remove any dust and bumps, wipe it clean with a slightly damp cloth or tact rag, let it dry or buff it dry with a dry cloth, then apply the next coat. Ensure dust free surroundings during application process and during drying time. (drying times differ due to humidity and room temperature)
