How to Prep for Painting: Furniture Protection

Unless you're working in an empty room, you'll likely have to move furniture out of your way at some point of the interior paint prep process. If you skip this step, you risk damaging the furniture or discovering the rough outline of a dresser or bed frame on the wall when you finally do redecorate. A similar problem pops up in bathrooms, where the wall color often makes an abrupt stop at the side of the toilet tank.Move items away from the wall towards the center of the room or remove them entirely. Cover the furniture with painter's plastic. And identify the items most vulnerable to paint damage, such as items with fabric upholstery, and take special care with them. If paint drips do get past your defenses, refer to avoid and remove paint drips to learn how to deal with them.

How to Prep for Painting: Wall Plate Removal

Once the furniture has been pulled away from the walls, you'll be able to see all the light switch and outlet covers. Remove them, along with any vent and return covers.Why interior paint prep matters: While you certainly can choose to paint over or around these items, the visual separation between the wall and the cover plates will be blurred. This leaves a ragged and unprofessional look to these items that are often highly visible. Also, when you do need to remove an outlet cover down the road, a paint covered outlet can lead to tearing and pulling loose the paint or drywall surface paper.Bonus tip: While removing the covers, you may find that some outlets are loose in the wall. If so, see Family Handyman's advice on how to Tighten a Loose Outlet.

How to Prep for Painting: Floor Coverings

Lay out floor coverings in the area where you'll be working. If you're painting a wall, it's a good idea to provide cover at least 3 feet away from the wall. If you're painting a ceiling, cover the entire floor. Canvas drop cloths are absolutely the best coverings for carpet. They're easy to spread out, and unlike plastic, they stay put without tape. And they won't cause your ladder to slip-slide on carpet. Just bunch them up a bit along walls and they'll stay where you want them. Normal drips and splatter won't soak through canvas, but heavy spills will. Pick up the drop cloths and scoop up spills with a broad putty knife or dustpan. These drop cloths aren't cheap, but you don't have to cover the entire floor. A long, narrow 'runner' is a good choice for your interior paint prep.Laying out protection saves your floors. But it also allows you the freedom to spread your painting tools out more than if they're constrained to a single area. This in turn allows you to work faster and with fewer restrictions. If you're getting ready to paint as part of a larger project, consider reviewing ways to protect your entire home during construction.

If you'll be painting anything more than a foot or so above your head, you should have appropriate platform support. For most DIY interior paint prep projects, this will be as simple as a stepladder. But if you're tackling a stairwell or vaulted great room, you'll want to look at setting up a scaffold system. Set up the scaffold before you need it, to make sure you don't lose your wet edge while painting. It's important to take the time to set up scaffolding securely, and double-check its stability.

This interior paint prep step is short but crucial. Before you open up a single can of paint, make sure you have something close at hand to use to wipe up spills. If you're using latex paint, have water and rags on hand. And if you're using oil-based or enamel paint, have mineral spirits or the thinner recommended by the paint manufacturer.
