Spray painting walls and doors like a pro requires preparation, the right equipment, and good technique. Here's a detailed step-by-step guide:
What You’ll Need:
Paint sprayer (airless for walls/doors)
Quality paint (usually water-based acrylic/latex for interior)
Drop cloths/plastic sheeting
Painter’s tape
Masking paper/plastic (for windows, trims, floors)
Respirator mask
Safety goggles & gloves
Sandpaper or sanding sponge (120–220 grit)
Tack cloth or microfiber rag
Primer (if needed)
Stir sticks and strainer (to avoid clogs)
1. Prep Like a Pro
For Walls:
Move furniture & cover floors with drop cloths or plastic.
Mask off trim, windows, outlets, ceilings (if not painting them).
Fill holes & sand any imperfections.
Clean surfaces of dust and grease.
For Doors:
Remove hardware (handles, locks, etc.).
If possible, remove the door and spray it flat on sawhorses.
Clean & sand lightly to dull the finish and improve adhesion.
2. Choose the Right Sprayer
Airless sprayer for walls/doors – fast and great for large areas.
Use fine finish tips (e.g., 311, 411) for smooth door finishes.
Adjust pressure: higher for walls, lower for doors (less overspray).
3. Prime If Needed
Bare wood, patched areas, or dramatic color changes = prime first.
Use a sprayer-compatible primer.
Lightly sand once dry for a smooth base.
4. Practice First
Test spray on cardboard or scrap wood.
Get a feel for the distance (usually 10–12 inches away), trigger control, and speed.
5. Spray Like a Pro
General Tips:
Keep the gun perpendicular to the surface.
Move in smooth, overlapping passes (50% overlap is ideal).
Always start and stop spray movement off the surface to avoid blobs.
Keep consistent speed and distance.
For Walls:
Use a larger spray tip (e.g., 515 for latex on walls).
Work in 3–4 ft vertical or horizontal sections.
Feather the edges to blend.
For Doors:
Use a fine finish spray tip (e.g., 311).
Spray top to bottom or side to side depending on the door style.
Multiple thin coats are better than one heavy one.
6. Dry & Sand Between Coats
Allow proper drying time (follow paint can instructions).
Lightly sand between coats (esp. on doors) with 220-grit for ultra-smooth finish.
Wipe down with tack cloth after sanding.
7. Clean Up Properly
Flush the sprayer with water or solvent (depending on paint type).
Store tools and leftover paint properly.
Optional: Back-Roll Walls
After spraying, some pros lightly back-roll walls with a roller to ensure even coverage and better adhesion, especially for porous surfaces.
Final Tips:
Don’t spray on windy days if you're outdoors.
Work in well-ventilated spaces.
Use a fan or air mover for faster drying and fume control.
Be patient – prep takes time, but it makes the biggest difference.
