Proper preparation is the foundation of every successful paint job. Before any color touches the wall, surfaces must be cleaned, repaired, and smoothed to ensure flawless coverage and long lasting durability. This FAQ answers the top questions homeowners ask about paint prep, sanding, and surface repair, with helpful Randall’s links included throughout.
Why is surface preparation so important before painting?
Prep work ensures paint adheres correctly, looks smooth, and lasts longer. Skipping prep can lead to peeling, uneven texture, flashing, and premature wear.
What does paint prep usually include?
Prep work often involves
- Cleaning surfaces
- Patching holes and cracks
- Sanding rough areas
- Repairing damaged drywall
- Caulking gaps
- Priming as needed
Painters evaluate the surface condition to determine which steps are required.
Do painters handle sanding and repairs or should homeowners do it?
Professional painters typically handle all sanding, filling, patching, priming, and surface correction. Homeowners can help by removing decor, unplugging electronics, and clearing workspaces to make the process efficient.

When is sanding necessary?
Sanding is essential when
- Walls have rough texture
- Paint is peeling
- Glossy surfaces need a scuff for adhesion
- Repairs have been made with patching compound
Sanding helps create an even, uniform surface for primer and paint.
How do I know if my walls need repair before painting?
Look for
- Nail pops
- Dents and dings
- Cracks
- Bubbled paint
- Water damage
- Uneven texture
If any of these are present, repairs should be completed before painting begins.
What products are used for repairing walls?

Do water stains or smoke stains need special prep?
Yes. Stains require stain blocking primer to prevent discoloration from bleeding through the topcoat. Without primer, stains will reappear even after painting.
When is priming required after surface repair?
Priming is necessary when
- New drywall is installed
- Stains are present
- Surfaces are patched
- Bare wood or metal is exposed
- Dark or bold colors need to be covered
Primer seals repairs and provides a consistent base for paint.
How long does prep work take?
Smaller rooms may require one to two hours. Larger spaces or homes with extensive repairs may need significantly more time. Painters determine the schedule during the consultation.
Can sanding create dust and mess?
Sanding does create some dust, but professionals minimize this by using drop cloths, vacuum sanders, and controlled cleanup methods. Good prep practices protect furniture, floors, and adjacent rooms.
What should homeowners do to prepare for the prep phase?
You can
- Move small items away from walls
- Remove pictures and shelves
- Clear tables and surfaces
- Keep pets and children away from the work zone
Painters take care of protective coverings and larger items.
How do professionals ensure walls are ready for paint?
They inspect the surface under proper lighting, run hands over repaired areas, and check for smoothness. Any flaws are sanded again or re-patched before primer goes on.
What happens if a surface is not prepped correctly?
You may experience issues such as
- Peeling
- Uneven sheen
- Visible pitches
- Cracks reappearing
- Poor adhesion
Proper prep prevents these problems and ensures a professional finish.
