Planning Your Interior Painting Project

Why a Clear Plan Saves Time & Money

Avoid wasted paint: Measure walls and calculate gallons before you buy.
Minimize disruption: Sequence rooms by use (e.g., start with guest rooms, finish with high-traffic areas).
Stay on budget: Know costs up front and compare quotes.

Calculating Paint & Supplies Needed

Measure wall area: width × height of each wall, minus windows/doors.
Determine coverage: standard paints cover ~350 sq ft per gallon.
Add 10% buffer: for touch-ups and future fixes.
Gather tools: drop cloths, painter’s tape, angled brushes, rollers, trays, ladder.

Prep & Tools for a Flawless Finish

Step-by-Step Wall & Trim Prep

Clean surfaces with trisodium phosphate (TSP) or mild detergent.
Fill holes and cracks with spackling compound, then sand smooth.
Mask off areas using painter’s tape along baseboards, trim, and outlets.
Prime as needed on new drywall, stained areas, or drastic color changes.

Must-Have Painting Tools

Angled sash brushes (2″–3″) for edges.
Rollers: ¾″ nap for smooth walls; 1½″ nap for textured surfaces.
Accessories: drop cloths, trays, liners, paint-edger tools.
Safety: sturdy ladder or small scaffold.

Cutting-In, Rolling & Drip Control

Cutting-in: load brush lightly; use long, smooth strokes.
Rolling: work in a “W” pattern, then fill in.
Drip control: don’t overload rollers; wipe drips immediately.

Step-by-Step Painting Techniques

Ceilings & High Walls

Use an extendable roller pole to minimize ladder climbs.
Paint in sections, maintaining a wet edge to avoid lap marks.
Ensure good ventilation for faster drying.

Doors, Windows & Built-Ins

Remove hardware (knobs, hinges) for a cleaner finish.
Sand lightly between coats for ultra-smooth semi-gloss.
Use a sash brush for precise trim work around windows.

Quick Touch-Up & Cleanup

Seal leftover paint in labeled containers for future touch-ups.
Clean latex brushes with soap and water; oil-based with mineral spirits.
Store roller covers in plastic bags during short breaks.
