Interior and Exterior Painting Guide

Why Quality Painting Matters

A fresh coat of paint is one of the most cost-effective ways to update your home's appearance and protect underlying surfaces. Quality painting work requires proper preparation, the right materials, and technique knowledge.

• Protects surfaces from weather and UV damage
• Improves aesthetic appeal and increases home value
• Extends the life of walls and exterior materials
• Creates a fresh, updated environment

Interior Painting Basics

Interior painting transforms living spaces with color and finish. Proper preparation and technique prevent issues like peeling paint, brush marks, and uneven coverage.

Pre-Painting Preparation

Success starts before you open the paint can. Proper prep work prevents costly redo work and ensures smooth, professional results.

• Clear furniture and protect floors with drop cloths
• Repair drywall holes and sand rough patches
• Clean walls to remove dust, dirt, and grease
• Prime raw drywall or new surfaces before painting
• Caulk gaps around trim, baseboards, and ceiling
• Mask edges around trim, windows, and baseboards with painter's tape

Choosing the Right Paint

Paint selection affects durability, appearance, and maintenance requirements. Different rooms and surfaces require specific finishes.

• Flat/Matte: Best for living areas; hides imperfections but shows marks easily
• Eggshell: Moderate sheen; durable and washable for bedrooms and hallways
• Satin: Higher sheen; excellent for kitchens and bathrooms due to moisture resistance
• Semi-Gloss: Very durable and washable; ideal for trim, doors, and high-traffic areas

Painting Technique

Proper technique prevents brush marks, streaks, and uneven coverage. Apply paint in controlled, overlapping strokes for consistent results.

• Use quality brushes and rollers for better coverage
• Apply thin, even coats rather than one thick coat
• Roll walls in a "W" pattern, then fill in the pattern
• Maintain a wet edge to avoid visible seams
• Cut in edges before rolling the field for better blending
• Allow proper drying time between coats

Exterior Painting Essentials

Exterior painting protects your home from weather while boosting curb appeal. Exterior work requires different materials and techniques than interior painting.

Surface Preparation for Exteriors

Exterior preparation is more demanding than interior work due to weather exposure and accumulated dirt. Thorough prep prevents peeling and premature failure.

• Pressure wash surfaces to remove dirt and mildew
• Scrape off loose or peeling paint
• Sand rough areas for better paint adhesion
• Fill cracks and gaps with exterior caulk
• Prime any bare wood or repaired areas
• Allow weather drying time after cleaning

Exterior Paint Selection

Exterior paints contain ingredients for weather resistance and UV protection that interior paints lack. The right paint type extends protection between repainting.

• Latex Exterior: Water-based; low VOC; easy cleanup; good UV resistance
• Acrylic Latex: Best for wood; excellent adhesion and flexibility
• Oil-Based Exterior: Traditional; excellent durability but requires mineral spirits cleanup
• Elastomeric: Flexible coating; fills small cracks and handles temperature changes

Weather Considerations

Weather conditions significantly impact painting success. Paint in appropriate conditions to ensure proper cure and application.

• Avoid painting in rain or high humidity
• Paint temperature should be 50-85°F during application and curing
• Avoid direct sun on surfaces you're actively painting
• Plan projects during mild weather seasons
• Allow extra drying time in cool or humid weather

Painting Project Cost Breakdown

Total painting costs include materials, labor, and preparation. Understanding cost components helps with budgeting and comparing contractor quotes.

Common Painting Mistakes to Avoid

Professionals distinguish themselves through preparation and attention to detail. Learning what not to do prevents costly redo work.

DIY vs. Professional Painting

Interior painting is achievable for most DIY enthusiasts with proper guidance. Exterior work and high ceilings often justify professional hire.

When DIY Makes Sense

• Single-story or standard ceiling heights
• Interior walls in good condition
• Color changes without significant prep
• You have adequate time (don't rush quality)

When to Hire Professionals

• Multi-story homes or vaulted ceilings requiring scaffolding
• Extensive surface preparation and repairs needed
• Exterior work involving climbing or power washing
• Tight timeline requiring quick completion
• High-visibility spaces where perfection matters
