Star Nails Resin Activator Spray 240ml is a fast setting activator. This fantastic formulation is less aggressive than traditional spray on activators, so it can be sprayed at a much closer distance resulting in a quick, smooth finish. Spray onto each layer of resin approximately 15cm from the nails between each layer of resin to set the nails hard. The activator can be sprayed twice on each layer to speed up the cure time.
