1. Skipping Surface Prep (Especially Before Painting)
✅ The mistake: Painting over dirty, glossy, or damaged walls.
✅ Why it matters: The paint doesn’t stick, peels off, or looks uneven.
Fix: Always clean, patch, sand, and prime. It makes a massive difference.

2. Rushing Drywall Repairs
✅ The mistake: Slapping on compound and painting it the same day.
✅ Why it matters: The patch shrinks, shows through paint, or creates weird textures.
Fix: Use multiple thin coats, let each dry fully, and sand smooth.

3. Not Using a Stud Finder
✅ The mistake: Screwing directly into drywall and hoping for the best.
✅ Why it matters: Your shelves, TV, or cabinets eventually rip out of the wall.
Fix: Use a stud finder every time.

4. Underestimating Time and Tools
✅ The mistake: Starting a project at 5pm with the wrong screwdriver and a YouTube video.
✅ Why it matters: You burn out, break something, or quit halfway.
Fix: Budget more time than you think — and check your tools first.

5. Ignoring Humidity and Temperature
✅ The mistake: Installing flooring, caulking, or painting in extreme heat or cold.
✅ Why it matters: Materials expand, contract, or fail to bond properly.
Fix: Always check the product’s working conditions — they matter more than you think.
6. Skipping Tape When You Actually Need It
✅ The mistake: Trying to “cut in by hand” around tricky edges without painter’s tape.
✅ Why it matters: Wavy lines, paint on the ceiling, and regret.
Fix: Use painter’s tape on ceilings, trim, tile edges, and awkward corners.

7. Starting a Project Without a Plan
✅ The mistake: Buying materials before you measure, prep, or check code.
✅ Why it matters: You waste time, overspend, or miss something crucial.
Fix: Slow down. Sketch it out, take real measurements, and know your steps before you start.
