If applying to unpainted grout ensure the Dulux Renovation Range Grout Pen is free from grease, dirt and other contaminates. The durability of the tip will decrease when used over unpainted grout.

Shake well with cap on before use and press down on the tip several times to get the paint to flow. Hold pen at 45-degree angle to the grout line. On vertical surfaces, paint from the bottom and work upward. When the paint flow thins, wipe the tip with a soft cloth and press the tip several times to reactivate paint flow. Apply two coats at least one hour apart. Keep capped and horizontal when not in use.
