Paint Trim or Walls First? And Other Painting Questions Answered
Professional painters share their secrets for producing a great-looking interior paint job. The work will go faster with less hassle too.
Roll Paint Along the Edges for Consistent Texture
Use a 3-in. roller with a nap that’s the same thickness that was used for the rest of the wall painting. Roll as close as you can without bumping the opposite wall or slopping paint onto the trim. Finish brushing on the paint and rolling it out in one area before moving on to the next section. Next, check out these 29 painting tool hacks to make your painting projects a breeze.
Prime and Texture Wall Patches to Avoid a Blotchy Finish
Primer seals the patch so paint won’t sink in and look dull. To match texture, prime with a roller, feathering out the edges. Choose a nap thickness to match the surrounding wall texture (a 3/8-in. nap roller for smooth walls; 1/2-in. for textured). Plus: See the game-changing painting tools our editors love.
Let Paint Dry, Then Cut the Tape Loose for a Perfect Edge
Once paint is dry, you can’t just pull the tape off the trim. Paint forms a film between the wall and the tape, and removing the tape tears pieces of dried paint off the wall. So before pulling off the tape, cut it loose.
Wait for the paint to completely dry at least 24 hours, then use a sharp utility knife or box cutter knife to slice through the film. Start in an inconspicuous area to make sure the paint is hard enough to slice cleanly. If you cut the paint while it’s still gummy, you’ll make a mess. As you cut the paint, pull up the tape at a 45-degree angle. Get more secrets of professional painters.
To Avoid Lap Marks when Wall Painting
To maintain a wet edge, paint an entire wall all at once. Start at one end, running the roller up and down the full height of the wall, moving over slightly with each stroke. Move backward where necessary to even out thick spots or runs. Don’t let the roller become nearly dry; reload it often so that it’s always at least half loaded. Keep the open side of the roller frame facing the area that’s already painted. That puts less pressure on the open side of the roller, so you’re less likely to leave paint ridges. Looking to paint your doors next, these are the tips you need to know.
Feather Out the Paint Where You Can’t Keep a Wet Edge
You can’t cover large areas like ceilings, extra-tall walls or stairwells in single, continuous strokes, so the best way to minimize lap marks on these areas is to feather out the paint along the edges that you can’t keep wet. The thinner, feathered coat of paint will avoid the buildup that causes the lap mark.
To paint a large section without leaving lap marks, roll the nearly dry roller in different directions along the dry edge, feathering out the paint as you go. After completing the entire length of the wall or ceiling, move to the next section and paint over the feathered edges. For the second coat, apply the paint in the opposite direction. This crisscrossing paint application sharply reduces (if not eliminates) lap marks.
Use Cotton Drop Cloths Rather Than Plastic
But even with canvas or rosin-paper drop cloths, large spills still need to get wiped up right away or they’ll seep through. Clean spills with paper towels or cloth rags. Likewise, if you splatter paint on any other surface, wipe it up immediately.
Sand Trim Between Coats for an Ultra-Smooth Finish
Mix Several Cans of Paint in a Large Bucket for Consistent Color
For large wall painting jobs, use the bucket and a roller screen rather than a roller tray. It’s much faster to load your roller with the screen than to use a roller pan. Simply dunk it into the paint bucket, then roll it along the screen until it stops dripping. Next, check out our favorite 5 gallon bucket hacks.
Clean Dirty Surfaces So the Paint Can Form a Strong Bond
Wipe on the cleaner in a circular motion using a lint-free cloth or abrasive pad. Start at the bottom and work up. After the surface is clean, fill in any nicks and holes, then sand them smooth before painting walls. The cleaners are available at paint stores, home centers and on Amazon. Be sure to wear rubber gloves and eye protection. Here are more tips for prepping walls before painting.
Paint the Trim First, Then the Ceilings and Walls
When painting the trim, you don’t have to be neat. Just concentrate on getting a smooth finish on the wood. Don’t worry if the door and trim paint gets slopped onto the walls. You’ll cover it later when painting walls. Once the trim is completely painted and dry (at least 24 hours), tape it off (using an ‘easy release’ painter’s tape), then paint the ceiling, then continue on to wall painting.
