Interior Painting Done Right: Cut In & Roll

Good paint work is mostly prep and patience. The painting itself follows a simple order: prep, prime, cut in, then roll. Get that sequence right and you'll skip the drips, roller marks, and ragged edges that give away a rushed job.

Prep: the part that actually matters

1. Clear and cover. Move furniture out or to the center, drop-cloth the floor, and take down switch and outlet covers.
2. Clean the walls. Wipe off dust, grease, and cobwebs. Paint won't bond to a dirty wall. Kitchens especially need a degreasing wash.
3. Patch and sand. Fill nail holes and dings (see our patch guide), sand smooth, and wipe off the dust.
4. Tape your lines. Run painter's tape along trim, ceilings, and anywhere you want a crisp edge. Press the edge down firmly so paint can't bleed under.

Prime when it counts

Prime new drywall, patches, stains, and big color changes. Primer seals the surface, blocks stains from bleeding through, and gives the color coat something even to grab, so patches don't "flash" as dull spots. Over a clean, similar-color wall in good shape, a quality paint-and-primer may be enough.

Cut in the edges

"Cutting in" is painting the borders with a brush where a roller can't reach, along the ceiling, corners, and trim. Load an angled brush, tap off the excess, and lay a steady band a couple inches wide. Do the cutting in for a wall, then roll that wall while the cut-in edge is still wet so they blend, this is the trick to no visible line between brush and roller.

Roll without lap marks

1. Load the roller evenly in the tray so it's coated but not dripping.
2. Work in sections. Roll a "W" or "M" a few feet wide, then fill it in without lifting, spreading the paint out.
3. Keep a wet edge. Always roll back into the paint you just laid before it dries. Rolling over half-dry paint is what leaves those streaky lap marks.
4. Finish each section with light, top-to-bottom passes to even the texture.

Know when to call a pro

Painting a room is a rewarding DIY project. Call for a hand when it's high or hard-to-reach work (stairwells, vaulted ceilings, exterior heights), when paint is peeling over a moisture problem (fix the moisture first), or when the home was built before 1978 and the work disturbs old paint, since lead-safe rules apply. And if you'd simply rather have a whole-house repaint done fast and crisp, that's what we're here for.
