Most air sprayers can be used either indoors or outdoors, and all of the models that we’ve looked at here can be used in both areas. This means you can easily use them on a wide range of different surfaces such as on furniture or even door frames and baseboards. The big thing to appreciate here is that a sprayer isn’t as accurate as a brush. Due to this, preparation is going to be vital and you need to ensure all areas you don’t want to paint are very well covered. You’ll also want to wear a mask along with covering your skin. If you’re working with fine paints at high power then it may take a while for the particles to land. It’s worth bearing this in mind as you’ll simply need to take extra care when you’re working indoors.
