When it comes to painting, a lot of people think it’s just about slapping on a fresh coat and calling it a day. But any good painter will tell you there’s a whole lot more to it if you want a finish that lasts and looks professional. Preparation is everything. If you rush into painting without getting the surface right, you’ll end up with peeling paint, uneven coverage, or worse – a job that needs redoing way sooner than it should.
First things first, cleaning the surface is a must. Dust, dirt, and grease can stop paint from sticking properly. For interiors, a sugar soap wash gets rid of built-up grime, while exteriors often need a good waterblast. If there’s mould or mildew, that needs to be treated too – painting over it won’t solve the problem, it’ll just show up again later.
Next up is sanding and filling. Rough surfaces or old flaking paint need to be sanded back to create a smooth base. If there are any cracks, gaps, or holes, they need filling with the right product – not all fillers are created equal, and using the wrong one can lead to shrinking or cracking later on. Once that’s done, another light sand helps blend everything in before priming.
Speaking of primer, this step is often overlooked, but it makes a huge difference. It helps the topcoat stick better and evens out any colour variations. On bare timber, it stops tannins from bleeding through, and on plaster, it seals the surface so the paint doesn’t soak in unevenly.
When it comes to actually applying the paint, technique matters. Cutting in properly around edges before rolling ensures sharp, clean lines. Using the right roller or brush for the job can also make a big difference in achieving a smooth, even finish. And of course, applying multiple thin coats is always better than one thick one – it dries better, adheres properly, and looks far more professional.
Choosing the right paint for the job is just as important as how you apply it. Interior paints come in different finishes for a reason – flat paints hide imperfections but aren’t as durable, while semi-gloss or gloss options are easier to clean but show more marks. Exterior paints need to be tough enough to handle the weather, especially in New Zealand, where UV exposure can be harsh. Using low-quality paint might save money upfront, but it won’t last, meaning you’ll be repainting much sooner than you should.
A quality paint job isn’t just about looks – it’s about protection too. Paint shields surfaces from moisture, sun damage, and general wear and tear. Taking the time to prep properly and use the right materials makes all the difference between a job that lasts for years and one that starts failing after a season or two.
At the end of the day, painting is one of those things where you get what you put in. A rushed job will always show, while a well-prepared, carefully executed one will not only look better but stand up to the test of time. If you’re not confident in getting it right, it’s worth calling in a professional – because fixing a bad paint job is often harder (and more expensive) than doing it right the first time.
