Paint supplies to buy before the next gallon

Painter’s tape, a 1/2-inch roller cover for typical walls, and a canvas drop cloth. The gallon of paint is not the supply that keeps paint off the floor.

Buy painter’s tape, a 9-inch roller cover with about a 1/2-inch nap, and a canvas drop cloth before you open the can. Wait on specialty sprays, sprayers, and a nap long enough for stucco unless the wall is actually that rough.

Walls you are about to patch may have started as a hanging job: studs and anchors. The rest of the category is at home improvement.

The supplies that show up in the finish

Paint quality matters. So does the edge. Tape that is burnished down, left to set, and pulled on time beats a steady hand on glass and stained trim. A cheap cover sheds fiber into the wall; the nap length decides whether the paint looks like a wall or a popcorn ceiling.

Drop cloths are the unglamorous line item. Canvas costs more than a plastic roll and gets used on the next room. Plastic belongs over furniture you cannot move, not under your shoes.

Tape, cover, cloth

The cover needs a 9-inch frame. That buy is in the roller frame guide. The line where the wall meets the trim is a sash brush, not a roller. Ceilings are a pole problem before they are a taller ladder.

After the walls dry

Sanding dust from the prep belongs in a shop vac. A household vacuum filter is a poor place for drywall fines.

Frequently asked questions

What roller nap should I buy for interior walls?
About 3/8 to 1/2 inch for smooth and lightly textured walls. Longer naps hold more paint and leave more stipple; save those for rough stucco and brick.
How long can painter’s tape stay up?
ScotchBlue Original is made to release cleanly within about 14 days. Pull it back on itself at a low angle once the paint is dry to the touch. Leaving any tape up for weeks is how edges tear.
Is a plastic drop cloth enough?
Plastic is fine under a ladder for a minute. On the floor you walk, canvas stays put and soaks up drips instead of tracking them.
