“One-coat coverage” is one of the most expensive little promises in home improvement, especially once you see your wall in daylight. We talk with Mile High Coatings founder and president David Nanninga about the most common DIY painting mistakes he sees and how to avoid them before you burn a weekend and still end up with streaks, thin spots, or a patchy finish.

We dig into why Colorado interiors so often need two coats, and how knockdown drywall texture makes rollers miss tiny crevices on the first pass. David also breaks down the three paint application methods, brush vs roller vs sprayer, and explains why the surface you’re painting matters as much as the color you pick. If you’ve ever wondered why doors and smooth trim show brush marks, or why a wall looks “fine” until light hits it, this will click fast.

Then we get practical about painter’s tape: tack levels, how long you can leave it on, and why textured walls invite paint to seep under the edge. David shares simple ways pros seal tape lines for a cleaner cut. Finally, we tackle the heartbreak of touch-up paint that never matches, plus whether old leftover paint is worth using when you move into a new place.
