'''Interior painting''' is one of the most impactful and cost-effective home improvement projects. A fresh coat of paint transforms a room's appearance, protects surfaces, and can increase property value. This guide covers the complete process from planning through completion.

== Planning Your Interior Paint Job ==

=== Choosing Paint Type ===

{| class="wikitable" style="width: 100%;"
|-
! Paint Type !! Dry Time !! Cleanup !! Odor !! Best For
|-
| '''[[Latex Paint|Latex/Acrylic]]''' || 1-2 hours || Soap and water || Low || Walls, ceilings, most interior surfaces
|-
| '''[[Oil-Based Paint|Oil/Alkyd]]''' || 6-8 hours || Mineral spirits || High || Trim, cabinets, high-wear surfaces
|-
| '''Hybrid Alkyd''' || 4-6 hours || Soap and water || Low-Medium || [[Painting Trim|Trim]], [[Painting Cabinets|cabinets]], doors
|}

=== Choosing [[Paint Finishes|Finish/Sheen]] ===

{| class="wikitable"
|-
! Room !! Recommended Finish !! Why
|-
| Ceilings || [[Flat Paint|Flat/Matte]] || Hides imperfections, no glare
|-
| Living rooms, bedrooms || [[Eggshell Paint|Eggshell]] || Subtle sheen, reasonably washable
|-
| Kitchens, bathrooms || [[Satin Paint|Satin]] || Moisture-resistant, very washable
|-
| Hallways, kids' rooms || [[Satin Paint|Satin]] || Durable, handles heavy cleaning
|-
| Trim, baseboards, doors || [[Semi-Gloss Paint|Semi-gloss]] || Maximum durability, easy to clean
|-
| Accent details || [[Gloss Paint|High-gloss]] || Dramatic shine, ultra-durable
|}

=== Estimating Paint Quantity ===

One gallon of paint covers approximately '''350-400 square feet''' per coat. For a standard room:

# Measure the perimeter (sum of all wall lengths)
# Multiply by ceiling height
# Subtract windows (~15 sq ft each) and doors (~21 sq ft each)
# Divide by 350 for gallons per coat
# Multiply by number of coats (usually 2)
# Add 10% for waste and touch-ups

== The Painting Order ==

Professional painters follow a specific sequence for the best results:

{| class="wikitable"
|-
! Step !! Area !! Reason
|-
| 1 || '''Ceiling''' || Drips and splatter fall on unpainted walls
|-
| 2 || '''Walls — [[Cutting In|cut in]]''' || Edges done while focus is fresh
|-
| 3 || '''Walls — [[Roller Painting|roll]]''' || Fill in cut-in borders with roller
|-
| 4 || '''[[Painting Trim|Trim and baseboards]]''' || Cover any wall paint that got on trim
|-
| 5 || '''[[Painting Doors|Doors]]''' || Painted last to avoid touching
|-
| 6 || '''Touch-ups''' || Final inspection and corrections
|}

== Room Preparation ==

Proper prep is 80% of a successful paint job — see [[Surface Preparation]] for detailed guidance.

=== Protecting the Space ===
* Move furniture to center of room; cover with plastic sheeting
* Lay canvas drop cloths on floors (canvas absorbs drips; plastic is slippery)
* Remove switch plates, outlet covers, and light fixtures
* Remove curtain rods and wall decorations
* Apply [[Masking and Taping|painter's tape]] to ceiling edges, trim, and windows

=== Repairing Surfaces ===
* Fill nail holes and small cracks with lightweight spackle
* [[Drywall Repair|Patch]] larger holes with drywall repair kits
* [[Sanding|Sand]] all repairs smooth with 150-grit sandpaper
* [[Caulking|Caulk]] gaps between trim and walls with paintable caulk
* Wipe all surfaces with a damp cloth to remove dust

=== Priming ===
Apply [[Paint Primer|primer]] when:
* Covering new or repaired drywall
* Making a dramatic color change (use tinted primer)
* Covering stains (use shellac-based stain-blocking primer)
* Surface was previously glossy (use bonding primer)

== [[Painting Ceilings|Painting the Ceiling]] ==

# Use flat/matte white ceiling paint (hides imperfections and roller marks)
# Cut in around the perimeter with a 2.5" angled [[Paint Brushes|brush]]
# Roll with a 3/8" nap [[Paint Rollers|roller]] on an [[Extension Poles|extension pole]]
# Work in one direction, maintaining a wet edge
# Apply two coats for full coverage
# Let dry completely before painting walls

== [[Painting Walls]] ==

# '''Box your paint''' — pour multiple cans into a 5-gallon bucket for consistent color
# '''Cut in''' all edges: ceiling line, corners, around trim, outlets
# '''Roll walls''' using W-pattern in 3-4 foot sections
# Maintain a wet edge — always roll into wet paint
# Apply light, even pressure; let the roller do the work
# Allow first coat to dry (2-4 hours for latex)
# Apply second coat following the same process

== Room-by-Room Guide ==

=== [[Painting Bathrooms|Bathrooms]] ===
* Use '''mold and mildew resistant''' paint formulas
* Choose [[Satin Paint|satin]] or [[Semi-Gloss Paint|semi-gloss]] finish for moisture resistance
* Ensure good ventilation (exhaust fan running during and after painting)
* Clean walls with mildew remover before painting
* Use moisture-resistant [[Paint Primer|primer]] on bare surfaces

=== Kitchens ===
* Degrease walls thoroughly with TSP before painting
* Use [[Satin Paint|satin]] finish for washability
* Consider [[Semi-Gloss Paint|semi-gloss]] behind stove and sink areas
* [[Painting Cabinets|Cabinet painting]] is a separate, more involved process
* Allow extra ventilation during painting

=== [[Painting Bedrooms|Bedrooms]] ===
* [[Eggshell Paint|Eggshell]] finish is the standard choice
* Consider [[Paint Color Psychology|color psychology]] — blues and greens promote calm
* [[Accent Walls|Accent walls]] add drama without overwhelming
* Low-VOC or zero-VOC paint recommended for better sleep and air quality

=== Living and Dining Rooms ===
* [[Eggshell Paint|Eggshell]] finish for elegant, subtle sheen
* Consider the room's lighting when choosing colors — see [[How to Choose Paint Colors]]
* Test paint samples on the actual walls in your lighting
* Coordinate with existing furniture and flooring

=== Hallways and Stairways ===
* Use [[Satin Paint|satin]] finish — hallways get more touching and scuffing
* Lighter colors make narrow hallways feel more spacious
* Consider durability — hallways are high-traffic areas
* [[Painting Stairs|Stair]] areas may require scaffolding or ladder platforms

== Ventilation and Safety ==

* Open windows and use fans for air circulation
* Even low-VOC paints benefit from ventilation during application
* Wear safety glasses when painting overhead (ceilings)
* Use a respirator with organic vapor cartridges for [[Oil-Based Paint|oil-based]] products
* See [[Painting Safety]] for comprehensive safety guidelines

== Cleanup ==

* '''[[Latex Paint|Latex paint]]''': Clean [[Paint Brushes|brushes]] and [[Paint Rollers|rollers]] immediately with warm soapy water
* '''[[Oil-Based Paint|Oil paint]]''': Clean with mineral spirits in well-ventilated area
* Remove [[Masking and Taping|tape]] while paint is slightly tacky, pulling at 45° angle
* Seal leftover paint cans tightly — place plastic wrap over can before lid
* Store paint in cool, dry place (not freezing)
* Dispose of paint properly — see [[Paint Disposal]]

== Common Interior Painting Mistakes ==

* '''Skipping [[Surface Preparation|prep]]''' — the #1 cause of poor results
* '''Cheap paint''' — premium paint covers better, lasts longer, and looks better
* '''Not enough coats''' — two coats is the standard minimum
* '''Cutting corners on [[Paint Primer|primer]]''' — leads to uneven coverage and stain bleed-through
* '''Painting in wrong conditions''' — too cold, too hot, or too humid
* '''Overloading [[Paint Rollers|rollers]]''' — creates drips and orange-peel texture
* '''Not maintaining wet edge''' — creates visible lap marks

== Frequently Asked Questions ==

=== How long does it take to paint a room? ===

A typical 12x12 bedroom takes '''4-8 hours''' for an experienced DIYer including prep, two coats, and cleanup. Plan for a full day if you include drying time between coats. A professional crew can complete the same room in 2-3 hours. Larger rooms, high ceilings, extensive [[Surface Preparation|prep work]], and multiple colors add time. Budget extra time for kitchens and bathrooms which require more cleaning and careful work around fixtures.

=== Should I paint the ceiling the same color as the walls? ===

'''White ceilings''' are the most common choice because they reflect light, make rooms feel taller, and create a clean, classic look. However, painting ceilings the same color as walls creates a cocooning, dramatic effect that works well in bedrooms and small rooms. A ceiling painted one shade lighter than the walls is a sophisticated compromise. '''Dark ceiling colors''' can create intimacy but make rooms feel smaller — best reserved for rooms with high ceilings.

=== Do I need to prime before painting interior walls? ===

You need [[Paint Primer|primer]] when covering '''new drywall''' (PVA primer), making a '''dramatic color change''' (tinted primer), covering '''stains''' (shellac-based primer), or painting over '''glossy surfaces''' (bonding primer). If you're repainting a wall the same or similar color and the existing paint is in good condition, you can usually skip primer and go directly to two coats of quality paint. Many premium paints now include built-in primer for routine repaints.

=== What is the best paint for interior walls? ===

'''100% acrylic [[Latex Paint|latex paint]]''' is the best choice for most interior walls — it offers low odor, easy water cleanup, fast drying, excellent color retention, and good washability. Premium brands like Benjamin Moore Regal Select, Sherwin-Williams Emerald, and Behr Marquee offer the best coverage and durability. For [[Painting Trim|trim]] and [[Painting Cabinets|cabinets]], consider hybrid alkyd formulas for a smoother, harder finish with the convenience of water cleanup.
