How to Use

Ensure the surface is clean, dry and free from dust, grease or loose debris before application. Shake the can thoroughly for 2–3 minutes once the mixing ball is heard. Hold or invert the can approximately 10–15 centimetres from the surface and spray using steady, continuous movement for consistent line width and opacity. For sharper edges and accurate layouts, use masking or line marking stencils where required. Allow adequate drying time before exposing marked areas to heavy traffic or adverse weather conditions. For best performance, apply in dry conditions at temperatures above 15°C.
