If you want to know how to paint a house fast, well using an airless spray gun is currently the fastest method painting drywall sheetrock plasterboard, whatever you call it….. Preparation is very important ensuring everything is ready to paint & is sanded. You must make sure everything is masked and taped up to ensure you dont get paint on anything you shouldn’t. Next step is make sure the areas are free from dust & contaminants by using a vacuum, so you dont blow dust from the spraygun onto a freshly painted wall. Once dry it can be difficult to sand off and the wall can actually feel like sandpaper itself.
