Spraying painting used to be synonymous with graffiti on external walls but thanks to some clever new solutions, it’s increasingly popular indoors as well.
Here we’ve grouped together the best tips, tricks and techniques you need to know if you want to transform your interior walls while making it look easy.
- Ventilation is key when it comes to interior spraying painting, both for the way the paint dries and your health
- A smooth motion a suitable distance away from the wall of at least a foot will achieve the best results
- Humidity and damp will cause your paint to run and spoil even the most accurately applied finish
- If you’re in doubt, keep the paint layers thin and build up with several coating to avoid pooling and running
Now that we’ve outlined a few of the basics, let’s dive right into the full range of fundamentals you need to know about. And if that sounds a little too much like hard work, you can always hire the experts to take care of everything while you sit back and put your feet up.
The choice is yours my friend!
Preparation is the secret to interior wall spray painting
Dusty, dirty and flaky walls can all do with a touch of TLC at the best of times, but spraying directly on top of them certainly won’t do the job.
The dust and dirt will spoil the finish and the flaky parts of the wall will just fall off and leave things looking worse before you know it.
Clearly you don’t want to be in that situation, so you need to know how to prep and clean your walls. A stiff handheld brush will knock off light flakes and debris, while a mild household detergent or mineral-based spirit will take care of the rest.
Just make sure you have adequate ventilation while the spirits evaporate to protect your health and wellbeing.
Obviously if you have something more serious like cracks and holes, you’ll need to reach for your filler. Make sure to sand it back so it’s smooth and flush to the surrounding wall, otherwise it will stand out like a sore thumb.
There’s no shame in a quick tester
Pick a patch you don’t mind redoing and practise your technique a couple of times. One of the most common issues is trying to do too much too soon, which is why plenty of novice interior spray painters end up rushing their work.
If you look at the pros who achieve the best finishes, they virtually all have the exact same technique. Smooth, steady and continuous motion is what we need here folks, otherwise you’ll pool the paint by covering some bits too slowly, and spread it out too much by moving too fast.
By having a quick practice session you can also work out the ideal distance to stand away from the wall.
Begin about one foot away as a starting point and then move closer and further away, paying attention to what happens to the paint that hits the wall. In no time at all you’ll find the sweet spot for your particular paint and delivery system.
We need to talk about ventilation
Breathing in too many fumes and particulates from spray paint is never good for your health, which is why ventilation and freely moving air is really important. The other reason is that if it’s too humid inside your space, you’ll find that the paint just doesn’t dry.
Excess moisture in the surrounding area will leach into the paint, causing it to run and drip on your walls if you’re not careful. You want a warm, dry and clean room to work in.
Getting these three things in order at the beginning will make sure that you can achieve the finish you’ve seen online or in the catalogues.
Thin coats do not require you to thin out the paint
When someone talks about “thin paint” you would be forgiven for thinking they’re suggesting you water it down.
While this is what you do with watercolours when you’re painting for leisure, you don’t want to do this with interior wall paint because you will change the way it dries and the finish it delivers.
Thin coats in the context of spray paint means standing around a foot back from the wall so the paint that leaves your delivery system is dispersed over a wider area.
This will deliver a thinner coat to the wall, but the paint itself has not been thinned out.
Why does this matter? Because if you stand too close and apply a very thick level of spray paint to an interior wall, it will pool on the surface and quickly start running down the wall. Once that happens you’re assured of a blotchy, uneven finish.
Order matters when you’re spray painting interior surfaces
Start by spray the first coat on your walls and then move to the ceiling and apply two full coats to it. Next up you’ll want 2-3 coats on your woodwork and trim before taping off and finishing the fine details with a brush or roller.
When you come to spray any given area, band it off by spraying the outer edges first and then moving in to fill the space in the middle. The key is to keep the spraying system’s tip right in the corner, allowing the spray to overlap on both sides.
This simple order of events will allow you to make quick and tidy progress without sacrificing the quality of your finish.
Do you need to use primer when spray painting indoors?
Often you won’t need one but there are certain specific combinations of spray-based paints and existing top surfaces that will work better with a primer.
