Interior Wall Painting

First things first, clean your walls. A little Dawn dish soap in some water on a sponge will cut through any grease or grime. Let it dry completely. Then, look for any dings or nail holes; use a flexible putty knife and some spackle for those minor repairs. Once that's dry, give any rough spots a light scuff-sand. Now, the most important part: get all that dust off. I'll even take a damp mop to the walls to make sure they're perfectly clean. You can't have good paint adhesion on a dusty wall, my friend.

Forget the 'paint and primer in one' marketing hype; for a professional job, you use a dedicated primer. Get it stirred up and pour some into your tray. Load up your roller—don't overload it so it's dripping. Roll the primer on the main wall sections with overlapping strokes. Then, grab a quality brush and 'cut in' all your edges and corners where the roller won't reach. Let that primer dry completely per the manufacturer's specs. This is what gives your paint a solid foundation.

Open up your can of latex paint and give it a really good stir with a stir stick. You want to make sure all the solids are mixed in perfectly for consistent color and sheen. Pour about half a tray's worth of paint. Go ahead and load your roller, working it back and forth in the tray so it's evenly saturated but not a drippy mess. Keep your cut-in brush handy. Now we're ready to make some money. Yeah, baby.

A lot of people want to reach for tape here, but for a ceiling line, a pro learns to cut a straight line freehand. Dip just the tip of your brush in the paint, maybe a third of the way up the bristles, and tap off the excess. Now, create a nice, clean line along the ceiling, baseboards, and all your trim. Work in sections you can manage, creating a wet band of paint that you'll roll into next.

Get your roller loaded with paint. Start on the wall with a 'W' or 'M' pattern to distribute the paint across a 3-to-4-foot section. Then, fill it in with parallel strokes, overlapping your last pass and the edges you just cut in. The key here is to always maintain a 'wet edge,' rolling from a wet area into a dry area. Don't press too hard; let the roller do the work. That's how you get a beautiful, uniform finish.

Check the paint can for the recommended recoat time. This is a critical step, buddy. You need to let this coat dry completely. Make sure you've got good airflow in the room to help it cure. Whatever you do, don't touch it. Rushing to a second coat or trying to fix something while it's tacky is a recipe for disaster.

With the wall fully dry, look it over in good light. Check for any thin spots or holidays you might have missed. If you find a drip, you'll have to lightly sand it down and then touch it up. Use your cut-in brush for any small areas. If your prep and application were solid, this step should be quick and easy. BAM!

Don't 'paint lazy' when it comes to cleanup. As soon as you're done, it's time to clean those tools. For latex paint, soap and water is all you need. Wash your brushes and rollers until the water runs clear—that's how you know they're truly clean. Clean out your paint tray, wipe up any spills, and dispose of everything properly. Good tools are an investment, so take care of them.
