The 5 Biggest Painting Mistakes Homeowners Make (And How to Avoid Them)

The 5 Biggest Painting Mistakes Homeowners Make (And How to Avoid Them)

By A Girl and Her Brush Interiors

We’ve all been there—standing in the paint aisle, overwhelmed by 100 shades of “white,” finally picking one, and then… disaster. The color looks completely different on the wall, there are streaks everywhere, and now you’re regretting ever starting this project.

Painting seems simple enough, right? Dip the brush, slap it on, done. But as a pro painter, I can tell you that most DIYers (and even some pros!) make common mistakes that can ruin the final look. Before you pick up that roller, let’s talk about the five biggest painting mistakes and how you can avoid them like a pro.

1. Skipping the Prep Work

I get it. You’re excited to start. But not prepping your walls is the #1 way to end up with a bad paint job. Dust, grease, and old paint drips all show through, and don’t even get me started on the importance of primer.

🔥 Pro Fix:

  • Clean walls with mild soap and water.
  • Patch any holes or imperfections.
  • Sand rough areas and old drips for a smooth finish.
  • ALWAYS prime if you’re painting over dark colors or glossy surfaces.

2. Choosing the Wrong Paint Type & Finish

Not all paint is created equal. Using the wrong finish in the wrong place can lead to streaks, peeling, or impossible-to-clean walls. Look for great quality paints and the different perks each offers!

🔥 Pro Fix:

  • Flat/matte – Best for low-traffic areas (living rooms, bedrooms).
  • Eggshell/satin – Great for walls that need easy cleaning (hallways, dining rooms).
  • Semi-gloss – Perfect for kitchens, bathrooms, trim, and doors (hello, wipeable!).
  • Washable Matte - You can also find washable mattes where you don't have the shiny finish but it's still WIPEABLE!! 

3. Using Cheap Brushes & Rollers

A $2 brush will leave you with streaks, uneven coverage, and bristle hairs stuck in your paint.

🔥 Pro Fix: Invest in quality tools! A good angled brush and a high-quality roller will give you a smooth, pro-level finish. ALSO, try an 18" roller... you will thank me later!!

4. Not Using Painter’s Tape Correctly

You either skip it (BIG mistake) or remove it at the wrong time, leading to messy edges.

🔥 Pro Fix:

  • Use high-quality painter’s tape (no, not masking tape! - FROGTAPE).
  • Apply firmly to create a tight seal.
  • Remove while the paint is still slightly wet to avoid peeling.

5. Rushing the Job

Painting is an art, not a race. Skipping drying times or doing one thick coat instead of two thin coats will leave you with drips, streaks, and regrets.

🔥 Pro Fix:

  • Be patient! Allow 2-4 hours between coats.
  • Do multiple thin coats instead of one thick one.
  • If using a roller, use long, even strokes in a W pattern for the best coverage.

Final Thoughts

Painting is one of the easiest ways to transform your home—but only if done the right way! Avoid these mistakes, take your time, and you’ll end up with a flawless, professional-looking result.
