Advanced Maxiflex™ Technology

The Dulux Weatherguard Castille Exterior Paint incorporates Maxiflex™ technology, designed to provide lasting elasticity and help bridge fine hairline cracks.

Exterior walls experience temperature changes and minor movement, which can contribute to the development of small surface cracks.

The flexible coating helps cover hairline cracks smaller than 0.2mm while maintaining a protective decorative finish.

Larger cracks and structural defects must be repaired using appropriate materials before painting.

Fine-Textured Matt Finish

The Dulux Weatherguard Castille 20L features a fine-textured matt finish that helps conceal minor imperfections in plastered surfaces.

Its subtle texture creates an attractive exterior appearance while reducing the visibility of small surface irregularities.

The warm Castille shade works particularly well with neutral trims, natural stone, brickwork and contemporary exterior colour schemes.

Actual colour appearance may vary depending on lighting, surface texture and screen settings.

Ideal Applications

Dulux Weatherguard Castille is suitable for properly prepared and compatible exterior surfaces, including:

• Exterior plastered walls

• Cement-rendered surfaces

• Concrete walls

• Fibre-cement surfaces

• Residential exterior walls

• Boundary walls

• Commercial building exteriors

• Suitable previously painted masonry surfaces

Other substrates may require specialised preparation and compatible primers.

Long-Lasting Exterior Weather Protection

The Dulux Weatherguard Castille 20L is formulated to provide durable protection against environmental exposure.

Exterior walls are continuously exposed to rain, sunlight, wind and temperature fluctuations. These conditions can gradually affect the appearance and performance of ordinary coatings.

Dulux Weatherguard helps maintain a protective finish while providing excellent water resistance and flexibility.

Its textured coating also helps improve the appearance of minor plaster imperfections, making it suitable for exterior renovation projects.

Surface Preparation and Application

Correct surface preparation is essential for achieving a durable, attractive finish.

Before applying Dulux Weatherguard Castille 20L, ensure that the surface is clean, sound and thoroughly dry.

For best results:

• Remove loose or flaking paint.

• Clean away dirt, dust, grease and other contaminants.

• Treat mould and algae using suitable cleaning products.

• Repair cracks and damaged plaster before painting.

• Apply the recommended primer or sealer where necessary.

• Stir the paint thoroughly before application.

• Apply using a suitable brush or roller.

• Apply two coats according to the manufacturer’s recommendations.

• Allow sufficient drying time between coats.

• Avoid painting during rain or unsuitable weather conditions.

The fine-textured formulation is intended for brush or roller application. Spray application is not recommended.

Coverage and Quantity Planning

The Dulux Weatherguard Castille 20L offers an approximate spreading rate of 4–6m² per litre per coat, depending on the surface condition and application method.

A 20-litre container may cover approximately:

• One coat: 80–120m²

• Two coats: 40–60m²

Actual coverage may vary depending on surface texture, porosity and application thickness.

The coating is generally touch-dry in approximately one hour, with a recommended recoating interval of around four hours under suitable conditions.

Always confirm the manufacturer’s current recommendations before application.
