Knowing When and How to Sand Before Painting

So, it’s clear that you should sand a surface before painting it. That said, you might wonder at what point should you perform this task. As previously mentioned, painting preparation involves several steps, so where does sanding come into play?

In truth, you might find yourself sanding at various points of the process, depending on the specific project. If you’re repairing drywall prior to home interior painting, for instance, you’ll want to sand down the dried caulk/joint compound so the patch job is flush with the rest of the wall.

In most cases, your initial sanding should take place after you’ve cleaned a given surface. It’s worth noting that coarse sandpaper can also get rid of dirt and debris via friction and heat, but water and detergent often do a better job of eliminating these substances. So, if you’re planning on painting your home’s face, exterior power washing should be the first thing on your checklist. Then, once dried, you can sand surfaces that need it most. This one-two-punch of cleaning and sanding will ensure the strongest adhesion for your paint.
