• Prime any bare metal with 1 coat of Dulux Trade Metalshield Quick Dry Metal Primer.

• Followed by 1 coat of Weathershield Exterior High Gloss.
• Apply with a brush only. For health and safety reasons relating to solvent based paints, do not spray.

Where a special process colour is to be used, or where there is a.strong colour change, more coats will be needed. When painting resinous wood or woodwork with a history of blistering, it is best use only light colours, especially on south facing elevations. To get the most benefits from this system, use as directed on good quality timber that conforms to BS EN 942: 1996, in conjunction with good component design.

Q. Why do I need a flexible primer?

A. The undercoat has excellent flexibility, which allows it to expand and contract with the substrate as temperature and humidity levels fluctuate. This flexibility helps to prevent cracking, peeling, and flaking, ensuring a long-lasting finish.
