Where’s the job?

Overview

• Weather-resistant coatings protect external wall surfaces from harsh weather, moisture and UV damage.

• Skill level: 3 / 5 (requires surface preparation, appropriate safety measures and careful product application).

• Typical duration: 0.5 – 1 day depending on surface area and number of coats.

Safety First

• Wear appropriate PPE including gloves, eye protection and a face mask when working with solvents and chemicals.

• Use sturdy ladders or scaffolding to safely reach higher areas.

• Ensure adequate ventilation when applying coatings, especially in enclosed outdoor spaces.

• Follow manufacturer guidelines on mixing, application temperatures and drying times.

Tools & Materials

Step-by-Step

1. Clean the surface – remove dirt, mould and any loose debris using a pressure washer or stiff brush.

2. Inspect and repair – fill in cracks and holes with appropriate filler to ensure a smooth surface.

3. Apply primer – use a primer suited to external surfaces to improve coating adhesion.

4. Mix and apply coating – follow the manufacturer’s instructions for mixing and apply evenly with a roller, brush or sprayer.

5. Allow to dry – ensure sufficient curing time between coats for durability.

6. Inspect final finish – check for even coverage and recoat any areas if necessary.

Completion Checks

• Check that the coating is evenly applied with no missed spots or drips.

• Ensure that curing times have been fully observed before exposing the wall to weather.

• Final inspection confirms a durable, weatherproof finish on all external surfaces.

When to Call a Pro Instead

For extensive surface areas, high elevations or if the wall shows signs of structural weakness, a qualified professional can ensure proper surface preparation, safety compliance and longevity of the finish.
