What to consider before painting your house exterior

From the Resene decorating blog

Is your house in need of a fresh finish on the outside? Or perhaps it’s just time for a makeover?

Planning is the most important part of painting your house. It might not be as much fun as picking the colour, but it will ensure all your efforts result in a long-lasting, high-performance – and beautiful – finish.

A textured home exterior and patio

Whatever exterior surface you are painting, planning and preparation are essential to getting a good, long-lasting final result.

Here are some key things to consider before painting your house, or garage, exterior.

Pre-project planning:

A deep green front door

Before painting weatherboards give them a thorough check for any signs of rot, mould or moss and replace any damaged ones.

Repainting your home exterior and patio

Plan to paint in fine weather, not too hot, but warm enough for the paint to try.

Pre-painting prep

Top tip: Don’t waterblast wood cladding as it can damage the surface. Instead clean well with Resene Timber and Deck Wash.

Repainting outdoor areas with high-gloss finishes

High-gloss finishes can show up imperfections on older or textures surfaces. Opt for matte or low sheen if that is an issue in your exterior project.

When to paint

Some things to try if you’re not sure it’s warm enough for your paint to dry:

Top tip: Start ahead of the sun and work your way around the building keeping ahead of the sun as you go.


Here’s a checklist of painting tools. You may not need all of them depending on the nature of your project.

Break down your paint project into smaller parts so you can finish one section before moving onto the next. This will help you feel like you are making progress as well as keep on track.
