4–6 hrs $60–$150 CAD pricing

What you'll need

Tools

  • 2.5" angled sash brush
  • 9" roller frame + 1/2" nap sleeves (2)
  • Roller tray + liners
  • Painter's tape (e.g. FrogTape)
  • Drop cloths
  • Spackle + putty knife
  • Sanding sponge (220 grit)
  • Step ladder

Materials (per ~12x12 room, 2 coats)

  • ~1 gallon premium interior latex (Behr Marquee, Benjamin Moore Regal, or CIL Smart3 — all stocked at Home Depot/Rona/Canadian Tire)
  • Primer only if covering dark colour or fresh drywall

Step 1 — Prep the room (45 min)

Move furniture to the centre, cover with plastic. Lay drop cloths along walls. Remove switch plates and outlet covers.

Step 2 — Patch and sand (30 min)

Fill nail holes with spackle. Let dry 20 min, sand smooth. Wipe walls with a damp microfibre cloth.

Step 3 — Tape edges (20 min)

Tape ceiling line, baseboards, and door/window trim. Press firmly with a putty knife for a clean seal.

Step 4 — Cut in (45 min)

Using the angled brush, paint a 2–3" band along ceilings, corners, and trim. Work in 4-foot sections so the edge stays wet.

Step 5 — Roll the walls (1 hr)

Load the roller evenly. Roll in a large "W", then fill in without lifting. Always finish each section with light top-to-bottom strokes for an even finish.

Step 6 — Second coat (after 4 hrs)

Repeat cut-in and rolling. Most modern paints need 2 coats for full coverage.

Step 7 — Pull tape & touch up

Remove tape while paint is still slightly tacky for crisp lines. Touch up any missed spots with the brush.

Pro tips

  • Buy ONE premium gallon instead of two cheap ones — coverage and durability are dramatically better.
  • Box your paint (mix multiple cans together) if you bought more than one — eliminates colour variation.
  • Save the can label — colour codes fade. Snap a photo too.
Editorial note. Wear appropriate PPE. When in doubt — especially with electrical, gas, or structural work — hire a licensed Canadian tradesperson. See our safety policy.
