Interior Painting 101: Lessons from a Handyman’s Brush

It’s about understanding the walls you’ve got, the paints you pick, and how all that comes together when the brush hits the surface. So let’s walk through what I’ve learned over the years.

Picking the Right Paint for Different Wall Materials

Around here in Tennessee, homes come in all shapes and ages. From older craftsman bungalows in Knoxville to newer builds around Nashville, the substrates we deal with most often are drywall, plaster, and occasionally wood paneling or brick.

Drywall

Drywall is the most common interior surface you’ll encounter. It’s forgiving and pretty easy to paint.

• Best paints: Acrylic latex (a fancy name for water‑based paint).
• Why I like it: Easy cleanup, low odor, dries relatively fast.
• Pro tip: Always use a primer on new drywall before color. Without it, your paint will soak in like a thirsty sponge and need extra coats.

Plaster

Older homes often have plaster walls. These guys are a bit trickier.

• Best paints: Again, a good latex works well. Sometimes I go with a paint/primer combo if the plaster is in good shape.
• Why: Plaster can be a bit softer than drywall. Latex resists cracking and holds up well.
• Watch out: If the plaster is chalky or flaky, you need to stabilize it first. That’s a whole other story, but worth doing.

Wood Paneling or Trim

Wood absorbs differently than gypsum products.

• Best paints: Latex or oil‑based primers with latex topcoats for most situations.
• Note: If you’re sealing tannin‑rich woods (like cedar), use a stain‑blocking primer before the finish coat.

Brick or Masonry (Interior)

Paintable, but a bit unique.

• Best paints: Masonry paint or acrylic latex with masonry primer.
• Tip: Brick is porous. You’ll want to seal it well or use a thicker product designed for the job.

The Tools and Techniques That Make the Job Easier

You could try painting with your socks and a butter knife, but why would you? The right tools make the project faster and the finish cleaner.

Brushes and Rollers

• Brushes: Use angled sash brushes for corners and edges. They give you control.
• Rollers: 3/8” to 1/2” nap is your go‑to for most interior walls. Textured walls might need a thicker nap.

Drop Cloths and Tape

You won’t regret laying down good protection. Old sheets work, but canvas drop cloths grip paint and are easier on bare feet.

Blue painter’s tape is my best friend. It helps keep lines clean without yanking paint off the wall.

Prep Work

Painting is 90% prep, 10% paint. If you don’t prepare right, the paint won’t cover right, and you’ll be repainting sooner than you want.

• Fill nail holes and cracks with spackling.
• Sand glossy or bumpy spots smooth.
• Wipe walls down if they’re dusty or greasy.

Primer: The Unsung Hero

Primer isn’t glamorous, but it saves you time and money in the long run. It helps paint stick and hides old stains so your final color looks even.

Different Types of Paint: Pros and Cons

There’s a lot of paint out there, and each type has its perks. Here’s what I’ve learned works well in real Tennessee homes.

Flat/Matte

Pros

• Hides imperfections well
• No sheen means little glare

Cons

• Harder to clean
• Best in low‑traffic rooms like bedrooms

Drying: Fast to touch, slower to cure.

Eggshell and Satin

Pros

• Slight sheen makes walls easier to wipe
• Great for living rooms, hallways

Cons

• Slight sheen can highlight bumps if the wall isn’t smooth

Drying: Usually touch dry within an hour or two.

Semi‑Gloss and Gloss

Pros

• Very durable and washable
• Perfect for kitchens, bathrooms, trim

Cons

• Highlights flaws because of shine
• Can show brush marks if applied poorly

Drying: Quick drying, but you might notice lap marks if you rush.

Paint + Primer Combos

Pros

• Cuts down on a separate primer coat
• Good in decent condition walls

Cons

• Doesn’t replace full primer on stains or tricky substrates
• Can be more expensive per gallon

Oil‑Based vs. Latex

These days most interior jobs use latex (water‑based). It dries fast, cleans up with soap and water, and has less smell.

Oil‑based

• Pros: Tough finish, great for trim and old wood
• Cons: Strong odor, longer dry times, needs solvents for cleanup

Latex has largely taken over interior work unless you’re doing very specific trim situations.

Final Thoughts from the Brush

Painting interior walls isn’t rocket science, but it does take respect for the materials and the tools. I always say, take your time prepping, pick the right paint for your wall type, and don’t skip the primer unless you enjoy doing extra coats.

Painting can be fun when you get the hang of it. And when you’re done, you’ll have a room that feels new again.
