How long should primer really be left before sanding?
With TULDA PT30 Multiprimer, correct flash-off and drying times are essential to achieving the right surface for the next stage of the repair.
Apply 1–3 coats, allowing 5–10 minutes flash-off between coats at 20°C. Once applied, allow a minimum drying time of 2–3 hours at 20°C, or 20 minutes at 60°C.
Once ready, the recommended sanding range is P360–P500 dry or P600–P1000 wet.
PT30 is a 2K HS acrylic primer developed for high build, easy sanding and professional refinishing.
