Surface Preparation

Correct surface preparation is essential for achieving a durable and professional-looking exterior paint finish.

Before application:

• Ensure the surface is clean, sound and suitably dry.
• Remove loose, peeling or flaking paint.
• Remove dirt, dust and surface contaminants.
• Repair cracks and damaged areas with appropriate repair products.
• Treat mould or algae appropriately where present.
• Identify and correct sources of persistent moisture or damp.
• Prepare previously painted surfaces according to Dulux recommendations.
• Apply a suitable primer or sealer where required.

Applying paint to an unstable or incorrectly prepared surface can negatively affect adhesion, appearance and long-term performance.

Application Recommendations

Stir the paint thoroughly before use and during application where required.

Apply using a suitable brush, roller or manufacturer-approved application method.

Follow the current Dulux instructions regarding:

• Surface preparation
• Primer requirements
• Number of coats
• Thinning requirements
• Drying time
• Recoating intervals
• Recommended application method
• Temperature requirements
• Suitable weather conditions

Avoid exterior painting when rain or unsuitable weather conditions are expected during application or before the coating has adequately dried.

Coverage

The actual coverage obtained from a 20L container can vary depending on:

• Surface porosity
• Surface texture
• Application method
• Existing coatings
• Condition of the substrate
• Surface preparation
• Number of coats required
• Recommended spreading rate

For accurate quantity calculations, consult the current Dulux Weatherguard technical information for the manufacturer’s recommended theoretical spreading rate.

Colour Consistency

For larger painting projects, purchase sufficient paint to complete the required area.

Before starting, check that all containers are the correct Portland colour. Where recommended, boxing or combining paint from multiple containers can help maintain greater colour consistency across large continuous wall areas.

Care and Maintenance

Exterior painted surfaces should be periodically inspected for dirt, biological growth, cracking or deterioration.

Clean compatible painted surfaces according to Dulux recommendations and repair damaged sections when required.

Avoid aggressive cleaning methods, harsh chemicals or abrasive equipment that may damage the paint coating.
