Process For Painting Exterior Surfaces
- Adequately cleaning surfaces – The first step involves pressure cleaning all exterior surfaces with an anti-mold and anti-fungus solution. A clean surface is essential for new paints or primers to stick well.
- Scraping and sanding – Before we can begin painting, it’s necessary to prepare the surfaces to get the best finish. When our painters are undertaking this part of the process, they use scrapers with special tungsten blades to remove previous paint coating, which has poor adhesion. We then use a mechanical sander to smooth out the area. Finally, sanding the surface is essential as it scuffs the surface to create adhesion for the following new coatings.
- Filling and caulking – Filling refers to fixing up any holes in the surface or gaps where the different building materials meet and can help inhibit any moisture from entering behind the new paint coating, protecting your surface.
- Priming the surface – We conduct priming to all previously painted enamel surfaces, and any area sanded back to bare as part of the preparation process. Priming exterior surfaces is vital to creating adhesion for the new coatings to stick. In addition, to extend the lifespan of the new paint job, priming all previously painted surfaces may be necessary if your paint coatings are heavily degraded.
- Applying premium topcoats – We always recommend applying two coatings of self-priming ultra-premium grade paint, such as Dulux Weathershield. It’s essential to understand how different sheen levels can protect and extend the life of the new paint.
Factors that can affect the cost of your exterior paint project
- Surface Preparation – When the previous coatings have mould and mildew growth or are heavily degraded, our paint team will require a significant amount of additional time preparing the surface. This can involve scraping and sanding away previous paint coatings that may be cracking, peeling and flaking. Given the extra time and work involved, this will increase the overall cost to paint your home or building.
- Existing Hazardous Coating – Any house or building built before 1978 will contain lead-based paint. Lead was used in paint in the early to late 19th century and can be extremely dangerous when it breaks down. Therefore, we use special safety precautions and methods when sanding and scraping a project with lead-based paint. These safety measures help ensure everyone on-site and located nearby is kept safe.

- Site Access – How easy or difficult it is to gain access to the exterior of your home or building can affect the cost of your project. For example, if there is no street parking available and our painters have to pay for parking, this will increase costs. Suppose you manage or own a commercial property where we can only paint when tenants are not on-site. In that case, this may mean paying our painters overtime rates and the job taking longer to complete.
- Height Access – When painting exterior surfaces, height access can either be easy to access or sometimes it can be highly challenging. For example, suppose your exterior painting job has easy access for painters trestles, and the building height is within their limits. In that case, you shouldn’t have too many issues. If, however, we need to hire mechanical height access equipment or purpose-built scaffolding to reach surfaces safely, this can escalate costs quickly.
- Paint Coatings – While many people are looking for budget alternatives to save money, it’s essential to realise that using cheaper paint is likely to negatively affect your investment when it comes to painting the exterior of your home or building. Cheaper paints won’t help to protect your exterior surfaces from the elements and can mean you will need to repaint sooner than you think. On all exterior surfaces, we recommend using Dulux Weathershield, typically in a low-sheen or semi-gloss finish. If your external surface is masonry render, we highly recommend using a high build elastomeric coating. This special coating looks like paint but is much thicker, which means it offers enhanced crack bridging performance and offers greater protection for your external walls.
- General Repairs -Depending on the condition of your home, you may need to organise some general repairs before we can paint. When the exterior surface of your home is weatherboard, you may need to allow for repairs to rotted timber. A specialised carpenter or builder usually looks after these repairs. Alternatively, if the exterior is predominately masonry, such as brick or renders, repairs may be necessary before we can begin. For example, repairing expansion joints, removing drummy areas or completing patch repairs to dents and scratches may be required.
Factors that can help you keep costs down include:
- Good condition – If your exterior surfaces are in good condition and don’t require a lot of preparation, this can help decrease the overall cost of painting the exterior of a house or building.
- Same colours – Generally, if you’re repainting a building but keeping the same colour scheme, a one coat refresh can suffice as long as you’re repainting more frequently. Applying coat refreshes can help reduce your costs, providing your exterior surfaces are in good condition and require minimal preparation.
- Low set dwellings – Painting the exterior of a low set dwelling requires little to no scaffolding or speciality height access equipment. No scaffolding helps to keep your costs down, as there are no set-up or dismantling costs.
