'''Painting walls''' is the most common home improvement project and one of the most cost-effective ways to transform a room. With proper [[Surface Preparation|preparation]], the right [[Painting Tools|tools]], and good technique, any homeowner can achieve professional-quality results.

== Before You Begin ==

=== Gathering Supplies ===

{| class="wikitable" style="width: 100%;"

=== Calculating Paint Needed ===

A standard gallon of paint covers '''350-400 square feet''' per coat. To calculate:

# Measure wall length and multiply by ceiling height for each wall
# Add all wall areas together
# Subtract windows (15 sq ft each) and doors (21 sq ft each)
# Divide total by 350 for number of gallons needed per coat
# Multiply by 2 for standard two-coat coverage
# Add 10-15% for waste and touch-ups

''Example: A 12' x 14' room with 8' ceilings = (2×12×8) + (2×14×8) = 192 + 224 = 416 sq ft. Minus 2 windows and 1 door = 416 - 51 = 365 sq ft. One gallon per coat, two gallons total.''

== Room Preparation ==

=== Step 1: Clear the Room ===

* Move furniture to the center of the room and cover with plastic sheeting
* Remove curtains, curtain rods, and wall decorations
* Remove all outlet and switch plate covers
* Remove light fixtures if possible (cap wires with wire nuts and tape)
* Cover floors with canvas drop cloths — overlap seams by 12 inches

=== Step 2: Clean the Walls ===

Dust and grease prevent paint adhesion. Clean walls thoroughly:

* '''General rooms''': Wipe with a damp cloth or dry Swiffer
* '''Kitchens''': Wash with TSP (trisodium phosphate) solution to remove grease
* '''Bathrooms''': Clean with mildew remover, let dry completely
* '''Smoker's homes''': Wash with TSP, then apply [[Paint Primer|shellac-based primer]]

=== Step 3: Repair Imperfections ===

* '''Nail holes''': Fill with lightweight spackle, let dry, sand smooth
* '''Cracks''': Widen slightly with a utility knife, fill with joint compound, tape if needed
* '''Dents''': Apply thin layers of joint compound, feathering edges
* '''Nail pops''': Drive a new screw 2 inches above/below, dimple and fill both spots
* '''Large holes''': Use a drywall patch kit — see [[Drywall Repair]]

After repairs dry, [[Sanding|sand]] smooth with 150-grit, then wipe away dust.

=== Step 4: Tape and Mask ===

* Apply [[Masking and Taping|painter's tape]] along ceiling lines, trim, and around windows
* Press tape edges firmly with a putty knife for a tight seal
* Tape over outlets and switches
* Extend drop cloths up the baseboards

=== Step 5: Prime If Necessary ===

Apply [[Paint Primer|primer]] if:
* Covering new drywall (use PVA drywall primer)
* Making a dramatic color change (use tinted primer)
* Covering stains (use shellac-based primer like Zinsser BIN)
* Painting over glossy surfaces (use bonding primer)
* Bare wood or patched areas are exposed

== Painting Process ==

=== Step 1: Box Your Paint ===

If using multiple gallons of the same color, pour them all into a 5-gallon bucket and mix thoroughly. This process, called "boxing," ensures uniform color across the entire room, as even same-batch cans can have slight variations.

=== Step 2: Cut In the Ceiling Line ===

Using a 2.5" angled [[Paint Brushes|brush]]:

# Dip brush 1/3 into paint, tap (don't wipe) against the side
# Start 1/2 inch from the ceiling-wall junction
# Paint a 2-3 inch strip along the ceiling line
# Go back and carefully push paint to the very edge
# Work in 3-4 foot sections for consistent results
# Keep a wet edge — don't let cut-in sections dry before rolling

See [[Cutting In]] for detailed technique.

=== Step 3: Cut In Corners and Trim ===

* Paint 2-3 inch strips in all corners (wall-to-wall junctions)
* Paint around door frames and window casings
* Paint above baseboards
* Paint around outlets and switches

=== Step 4: Roll the Walls ===

Using a loaded [[Paint Rollers|roller]] with proper nap:

# Load the roller evenly — roll back and forth in the tray or on the bucket screen
# Start with a '''W pattern''' (or M pattern) about 3 feet wide
# Without reloading, fill in the W with even, overlapping strokes
# Roll from floor to ceiling in smooth, straight lines
# Apply light, even pressure — let the roller do the work
# Slightly overlap each section with the previous one
# '''Maintain a wet edge''' — always roll into wet paint, never into dry
# Work in 3-4 foot wide sections across the wall

'''Critical tips:'''
* Don't press too hard — this causes roller marks and uneven coverage
* Don't roll too fast — this causes splatter (especially with flat paint)
* Reload the roller frequently for consistent coverage
* For the final pass, roll lightly from floor to ceiling without stopping ("laying off")

=== Step 5: Apply Second Coat ===

* Wait for the first coat to dry completely (2-4 hours for [[Latex Paint|latex]], 24 hours for [[Oil-Based Paint|oil-based]])
* Repeat cutting in and rolling process
* Two coats provide better coverage, richer color, and longer durability
* Some dark-to-light color changes may need three coats

== Painting Order for a Room ==

{| class="wikitable"
|-
! Order !! Area !! Why This Order
|-
| 1 || Ceiling || Drips fall on unpainted walls
|-
| 2 || Walls (cut in) || Edges first while you're fresh
|-
| 3 || Walls (roll) || Fill in the cut-in border
|-
| 4 || Trim/baseboards || Clean up any wall overlap onto trim
|-
| 5 || Doors || Last to avoid touching while working
|-
| 6 || Touch-ups || Final inspection and corrections
|}

== Drying and Curing ==

{| class="wikitable"
|-
! Paint Type !! Touch Dry !! Recoat Time !! Full Cure
|-
| [[Latex Paint|Latex/Acrylic]] || 1 hour || 2-4 hours || 30 days
|-
| [[Oil-Based Paint|Oil/Alkyd]] || 6-8 hours || 24 hours || 30 days
|-
| [[Chalk Paint|Chalk Paint]] || 30 minutes || 1-2 hours || 30 days with wax
|}

'''Important''': Paint is dry to touch long before it fully cures. Avoid washing or scrubbing painted walls for at least 30 days after painting.

== Removing Tape ==

* Remove tape while the final coat is still slightly tacky (not fully dry)
* Pull at a '''45-degree angle''' away from the painted surface
* Pull slowly and steadily — jerking can tear paint
* If paint has dried, score along the tape edge with a utility knife first
* Touch up any bleed-through with a small artist's brush

== Cleanup ==

* '''[[Latex Paint|Latex paint]]''': Clean brushes and rollers with warm soapy water immediately
* '''[[Oil-Based Paint|Oil paint]]''': Clean with mineral spirits or paint thinner in a well-ventilated area
* Seal leftover paint tightly — place plastic wrap over the can before pressing the lid
* Store paint in a cool, dry place away from freezing temperatures
* Remove drop cloths carefully, folding paint drips inward
* Replace outlet covers and switch plates

== Common Mistakes ==

* '''Skipping prep''': The #1 cause of poor results — see [[Surface Preparation]]
* '''Not priming''': Leads to uneven coverage, stain bleed-through, and poor adhesion
* '''Overloading the roller''': Causes drips, runs, and orange-peel texture
* '''Not maintaining a wet edge''': Creates visible lap marks
* '''Painting in extreme temperatures''': Below 50°F or above 85°F affects drying and adhesion
* '''Using cheap paint''': Premium paint has better coverage, adhesion, and durability
* '''Removing tape too late''': Pulls dried paint off with it

== Frequently Asked Questions ==

=== How many coats of paint do walls need? ===

Most walls need '''two coats''' for proper coverage, color depth, and durability. You may need three coats when making a dramatic color change (dark to light or vice versa), or when covering red, orange, or deep blue tones. Using a tinted [[Paint Primer|primer]] as a first coat can reduce the number of finish coats needed.

=== How long should I wait between coats? ===

For [[Latex Paint|latex paint]], wait '''2-4 hours''' between coats. For [[Oil-Based Paint|oil-based paint]], wait '''24 hours'''. Always check the manufacturer's label for specific recoat times. Humidity and temperature affect drying — in humid conditions or cool temperatures, allow extra drying time. The paint should feel completely dry and not tacky before applying the next coat.

=== Can I paint over dark walls with light paint? ===

Yes, but expect to need '''3-4 coats''' or use a strategy: apply a tinted primer first (gray primer works well under most colors), then two coats of your finish color. This saves time and paint compared to applying multiple finish coats. Using a high-hiding paint formulated for color changes also helps.

=== What is the best [[Paint Finishes|paint finish]] for walls? ===

'''[[Eggshell Paint|Eggshell]]''' is the most popular finish for living rooms, bedrooms, and dining rooms — it offers a subtle sheen, hides minor imperfections, and is reasonably washable. Use '''[[Satin Paint|satin]]''' in kitchens, bathrooms, hallways, and kids' rooms for better washability. Use '''[[Flat Paint|flat/matte]]''' on ceilings to hide imperfections.

=== Do I really need to use painter's tape? ===

Not necessarily. Professional painters typically '''[[Cutting In|cut in]]''' freehand without tape, which is faster and often produces cleaner lines. However, tape is recommended for beginners and DIYers who aren't confident in their brush control. If you use tape, make sure to press the edges firmly and remove it while paint is still slightly tacky.
