General Main Points on Interior House Painting
Here are a few tips to make your painting projects go smoother and faster while giving you a professional-looking finish that you'll be proud of. You'll also find ingenious tips that can cut your cleanup time in half and extend the life of your paint brushes.
1. Lap marks are those ugly stripes caused by uneven layers of paint buildup. They occur when you roll over paint that’s already partly dry. The key to avoiding lap marks is to maintain a “wet edge,” so each stroke of your roller overlaps the previous stroke before the paint can begin to dry.
To maintain a wet edge, start near a corner and run 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.
2. Paint color may vary slightly from one can to the next. If you have to open a new can in the middle of a wall, the difference may be noticeable. Mixing the paints together eliminates the problem. It’s best to estimate the amount of paint you’ll need and mix it.
When coverage is difficult to estimate, add more rather than less. You can always pour the leftover back into cans. For large 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 the roller into the paint bucket, then roll it along the screen until it stops dripping.
3. 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.
4. Pros usually follow a certain order when painting a room. They paint the trim first, then the ceiling, then the walls. That’s because it’s easier and faster to tape off the trim than to tape off the 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 trim paint gets onto the walls. You’ll cover it later when painting the walls. Once the trim is completely painted and dry (at least 24 hours), tape it off, then paint the ceiling, then the walls.
5. If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs.
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. The cleaners are available at paint stores and home centers. Be sure to wear rubber gloves and eye protection.
6. Corners and areas next to trim that are painted only with a brush have a notice- ably different texture than the surrounding paint. To ensure the finished texture will be consistent in these areas, brush on the paint, then immediately roll it out before the paint dries.
7. Spills and spatters happen, regardless of how careful you are. It’s a lot easier to pre- pare for them than to wipe them out of your carpeting or off your wood floor later. All it takes is canvas drop cloths in your work area. The thick canvas stays in place, so you don’t need to tape it, and you can use it to cover any surface. Plastic drop cloths are slippery to walk on or set a ladder on and don’t stay in place. Even worse, paint spills on plastic stay wet, and they can end up on your shoes and get tracked through the house. Canvas is slippery on hard ﬂoors, so rosin paper is better over vinyl, tile and hard- wood. Tape the sheets together and to the ﬂoor to provide a nonslip surface.
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.
