Repainting the inside of your home can feel like a fresh start—new color, new vibe, maybe even a new season. But before you pop open that can of paint, there are a few things that often get overlooked. And skipping them? That can mean poor coverage, uneven textures, or paint that starts chipping way too soon. The prep stage is where the magic (or the mess) begins.
Wall Prep: More Than Just a Quick Wipe Down
Let’s start with surface prep. Most folks assume a simple wipe with a damp cloth is enough, but according to data from the Painting Contractors Association, improper surface preparation is the top cause of early paint failure. That means things like dust, grease, or leftover soap residue can cause your paint to bubble, peel, or crack. Walls should be cleaned with a mild detergent or degreaser—especially in high-traffic spots like hallways, kitchens, or around light switches. And if you’re painting over a glossy finish? It needs to be scuffed up so the new layer can actually grip.
The Patch Job You Didn’t Know You Needed
Take a walk around your space with the light hitting at an angle. See those small dents or nail holes? They’ll stick out like a sore thumb once the paint dries. Patching and sanding are crucial, even for tiny flaws. It’s a step many skip, but it plays a big role in that pro-level finish. Your walls are like a canvas—if the base isn’t smooth, the final look won’t be either.
Primer Isn’t Optional
Think of primer as insurance for your paint. It helps seal porous surfaces, blocks stains, and creates an even tone—especially if you’re going from dark to light colors. If your walls have water stains, smoke damage, or were previously painted in a bold hue, priming is a must. Skipping primer might save time now, but it’ll cost you later when the color starts fading unevenly.
Temperature, Humidity, and Other “Invisible” Issues
Paint doesn’t play well with extreme temps or moisture. If you’re painting during a humid Delaware summer or in a poorly ventilated room, the paint might take longer to dry and could even develop mildew. Professional painters keep an eye on humidity levels and often use dehumidifiers or fans to create a controlled environment.
Don’t Forget These Before You Grab a Brush:
- Clean the walls thoroughly, not just with water—use a degreaser if needed.
- Patch and sand even the tiniest dings for a smooth base.
- Use the right primer depending on surface condition and paint color.
- Control your environment—avoid painting in rooms that are too humid or too cold.
