Buy once, paint better

Cheap foam brushes and overloaded trays cause drips and texture. A short, solid kit costs less than a wasted gallon of finish paint. Use this list before you shop — then calculate gallons with the paint calculator.

Must-have painting tools

Optional but worth it: paint edger for ceilings, microfiber cloths, TSP substitute for cleaning, and a roller spinner for cleanup.

  • 9-inch roller frame + quality covers (3/8" nap for smooth walls; 1/2–3/4" for light texture)
  • 2–2.5 inch angled sash brush for cutting in (buy one good brush, not three cheap ones)
  • Paint tray + liners (or a 5-gallon bucket with roller screen for larger rooms)
  • Extension pole for walls and ceilings
  • Painter’s tape (blue or green) + plastic or canvas drop cloths
  • Putty knife, sandpaper (120–220), caulk for trim gaps
  • Screwdriver for outlet covers; ladder or sturdy step stool

Match roller nap to the surface

Worn covers leave fuzz in the film. Replace covers when they mat or shed — one spare cover per color is cheap insurance.

  • Smooth drywall / light orange peel → 3/8 inch nap
  • Medium texture / popcorn touch-ups → 1/2 to 3/4 inch
  • Ceilings → often same nap as walls; use a dedicated cover to avoid lint transfer
  • Trim → brush only, or mini foam rollers for flat door panels

Prep supplies before the paint aisle

Cleaning solution, patch compound, and primer are prep — buy them before finish paint so you are not stuck mid-project. See how to prep walls for painting and how to choose primer.

Frequently asked questions

What brush size for cutting in walls?

A 2 to 2.5 inch angled sash brush is the DIY standard for walls and ceilings. Larger brushes hold more paint but are harder to control along trim.

Do I need an expensive roller frame?

A sturdy metal frame that locks the cover matters more than brand prestige. Spend on covers — they control texture and coverage.

Canvas or plastic drop cloths?

Canvas stays put and absorbs drips on floors. Plastic is fine for furniture and for covering carpet when taped carefully — it can be slippery underfoot on hard floors.
