Prepping Your Walls Like a Pro: A Step-by-Step Painting Checklist 

It’s tempting to dive right into painting, especially when you’ve picked out the perfect color and want instant results. But one of the biggest differences between a DIY job and a professional-looking finish comes down to one thing: prep. 

We worked with a client, Derek, who had painted his living room himself. The color choice was spot-on, but peeling paint and roller streaks started showing within months. 

Why? Poor prep. 

When he brought us in for round two, we made sure to properly clean, patch, prime, and protect -- and the difference was night and day. 

Whether you’re painting yourself or hiring a pro, prepping your walls properly will make or break the final result. Here’s your step-by-step guide. 

Step 1: Clear and Protect the Area

• Move furniture out or to the center of the room and cover it with plastic sheets

• Lay down drop cloths to protect floors

• Remove wall décor, outlet covers, and switch plates
  

Pro Tip: Use painter’s tape to protect baseboards, trim, and any areas you don’t want painted

Step 2: Clean the Walls Thoroughly

Paint won’t stick properly to walls with dust, dirt, or grease.

• Wipe walls down with a damp sponge and mild soap

• In kitchens or bathrooms, use a degreaser

• Let the walls dry completely before moving on
  
  

Step 3: Repair Holes, Dents, and Cracks

You don’t want your new paint highlighting old damage.

• Fill holes with spackle or joint compound

• Sand smooth once dry

• Repeat for any surface imperfections (including drywall tape seams)
  
  

Step 4: Sand for a Smooth Surface

Even if you haven’t patched anything, sanding helps paint adhere better.

• Lightly sand glossy surfaces to dull the sheen

• Use a sanding pole for large areas and a sanding sponge for corners

• Wipe walls with a tack cloth or damp rag afterward to remove dust
  
  

Step 5: Prime Where Needed

Not all walls require primer -- but many do. Use primer if:

• You’ve repaired damaged areas

• You’re painting over dark or bold colors

• The surface is stained or porous (like new drywall or bare wood)

• You’re switching from oil-based to latex paint
  
  

Step 6: Final Check Before You Paint

• Make sure the surface is clean, smooth, and dry

• Confirm you’ve taped off edges and trim

• Stir paint thoroughly and use quality brushes or rollers
  

Optional Bonus Prep: Consider a tinted primer to help with better coverage when switching colors

Summary and Conclusion

Paint is only as good as the surface it goes on. By following this simple prep checklist, you’ll ensure better adhesion, smoother coverage, and a more professional finish that lasts.
