Painting a room yourself is one of the highest-return DIY projects you can do. A professional paint job can cost $500–$1,500 per room. Doing it yourself costs under $100 in supplies — and if you know what you’re doing, the results are indistinguishable. Here’s everything you need to know to do it right the first time.

What You’ll Need

• Paint — budget 1 gallon per 400 sq ft of wall space
• Painter’s tape — the good stuff matters. Frog Tape leaves cleaner lines than cheap tape. Shop painter’s tape on Amazon.
• Roller and roller cover — 9-inch roller, ½-inch nap for textured walls, ⅜-inch for smooth. Shop paint roller sets on Amazon.
• Angled brush — 2.5-inch for cutting in at edges
• Drop cloths — canvas is reusable and better than plastic. Shop drop cloths on Amazon.
• Extension pole for the roller — saves your back enormously

Step 1: Prep the Room (This Is Where Most People Go Wrong)

The reason DIY paint jobs look bad is almost never the paint — it’s the prep. Professionals spend more time preparing than painting. Move furniture to the center and cover it. Remove outlet covers and switch plates. Fill nail holes with spackle, let dry, sand smooth. Wipe walls with a damp cloth. Tape off trim and ceiling edges.

Step 2: Choose the Right Finish

• Flat/matte — hides imperfections, not washable. Best for ceilings and low-traffic areas.
• Eggshell — slight sheen, more washable. The go-to for most living rooms and bedrooms.
• Satin — more sheen, very washable. Great for hallways and high-traffic areas.
• Semi-gloss — highly washable. Best for kitchens, bathrooms, and trim.

Step 3: Cut In First

“Cutting in” means painting the edges — along the ceiling, baseboards, and corners — with an angled brush before you roll. Do all your cutting in before you touch the roller. Dip just the bottom third of the bristles and work in 3–4 foot sections, keeping a wet edge to avoid lap marks.

Step 4: Roll in a W Pattern

Load your roller evenly — roll it in the tray until fully coated but not dripping. Apply to the wall in a large W shape, then fill in without lifting the roller. Work in 3×3 foot sections, keeping a wet edge. Roll floor to ceiling and overlap each section slightly. Don’t press too hard — let the roller do the work.

Step 5: Two Coats, Always

One coat almost never looks good. Let the first coat dry completely (usually 2–4 hours) before the second. The second coat is where the color really comes alive.

Step 6: Remove Tape While Paint Is Still Slightly Wet

Remove painter’s tape at a 45-degree angle while the paint is still slightly tacky — not fully dry. If you wait until it’s fully dry, the tape can peel the paint with it. Pull slowly and steadily.

Track Your Paint Colors

Once you’ve found a color you love, write it down somewhere you’ll actually find it. Nothing worse than needing to touch up a wall two years later and having no idea what color it was. HomeLog has a free Paint Colors tracker where you can log the exact color name, brand, finish, and which room it’s in — so you always have it when you need it.
