Why Paint Matters

Paint does more than add color - it protects surfaces, establishes mood, creates visual flow between rooms, and dramatically affects how spaces feel. The difference between a rushed paint job with builder-grade paint and a professional application of premium products is immediately visible and impacts daily living for years.

In a whole-home remodel, painting represents one of the final finish phases and is highly visible in photographs and daily life. Colors chosen months earlier during design finally come to life on your walls. This is not the place to cut corners - premium paint costs only 20-30% more than budget options but provides dramatically better coverage, durability, and color retention.

Professional painters understand critical preparation steps that make paint last: proper cleaning, sanding, priming, caulking, and application technique. They also complete projects much faster than DIY efforts while achieving superior results. For whole-home projects, professional painting is almost always worth the investment.

Step-by-Step Guide

1

Finalize Color Palette and Finishes

Finalize all paint colors from your design selections. Test large samples on actual walls before committing. Choose appropriate sheen for each surface type. Create a room-by- room color schedule with paint codes for the painting crew.

  • Paint large samples (at least 12x12") on walls to test
  • View samples in morning, afternoon, and evening light
  • Select trim color (typically white or off-white)
  • Choose ceiling color (flat white or tinted to match walls)
  • Create color schedule document for painter reference
2

Calculate Paint Quantities

Measure all paintable surfaces and calculate gallons needed. A gallon covers approximately 350-400 square feet per coat. Order 10% extra for touch-ups and future repairs. Keep records of exact colors for future reference.

  • Calculate wall square footage per room
  • Deduct 20 sq ft per door and 15 sq ft per window
  • Plan for two coats on all surfaces
  • Order primer for new drywall and color changes
  • Keep one quart of each color for touch-ups
3

Prepare All Interior Surfaces

Surface preparation determines 80% of paint job quality. Clean all surfaces, sand glossy areas, fill holes and cracks, caulk gaps, and prime as needed. New drywall must be primed to seal porous paper surface.

  • Dust and clean all surfaces to remove construction residue
  • Sand any rough spots or raised areas smooth
  • Fill nail holes, dents, and cracks with spackle
  • Caulk gaps between trim and walls with paintable caulk
  • Apply primer to new drywall, patches, and color changes
4

Paint Ceilings First

Paint ceilings before walls to catch drips and avoid touching up finished walls. Use flat ceiling paint in white or slight tint. Cut in around edges with brush, then roll main field. Work in sections maintaining wet edge.

  • Use flat or dead-flat sheen to minimize imperfection visibility
  • Cut in 2-3" at ceiling/wall junction with angled brush
  • Roll in parallel passes maintaining wet edge
  • Apply two coats for consistent coverage
  • Allow proper dry time between coats (4+ hours)
5

Paint All Walls

Paint walls using cut-in and roll technique. Cut in corners, edges, and around trim with brush while another person follows with roller for wet edge blending. Work one wall at a time for consistent appearance.

  • Cut in around trim, corners, and ceiling line first
  • Roll walls while cut-in edges are still wet
  • Use W pattern when rolling for even distribution
  • Finish with vertical strokes for uniform appearance
  • Apply two full coats allowing proper dry time
6

Paint Trim and Millwork

Paint all trim with semi-gloss or satin for durability and easy cleaning. Baseboards, door casing, window casing, and crown molding typically share one color. Use quality brush or spray for smooth finish without brush marks.

  • Lightly sand pre-primed trim before painting
  • Apply with quality angled brush in direction of grain
  • Use foam mini roller for flat trim surfaces
  • Apply two finish coats for durability
  • Remove painter's tape before paint fully cures
7

Paint Interior Doors

Paint doors with semi-gloss for durability around high-touch areas. Remove doors from hinges for best results, or paint in place with careful technique. Paint edges to match room the door opens into.

  • Remove hardware before painting
  • Sand door surface lightly for adhesion
  • Paint panels first, then stiles, then rails
  • Paint edges to match receiving room color
  • Allow doors to dry fully before reinstalling hardware
8

Prepare Exterior Surfaces

Exterior painting requires thorough preparation to ensure paint adhesion and longevity. Power wash all surfaces, scrape loose paint, sand rough areas, prime bare wood, and caulk all joints and gaps.

  • Power wash siding, trim, and painted surfaces
  • Allow 24-48 hours dry time after washing
  • Scrape and sand all loose or peeling paint
  • Prime bare wood and any repairs with exterior primer
  • Caulk all joints, gaps, and penetrations
9

Paint Exterior Surfaces

Apply two coats of exterior paint in appropriate weather conditions. Temperature should be 50-85F with low humidity and no rain expected for 24 hours. Work in shade when possible - direct sun causes paint to dry too fast.

  • Paint trim and detail work first with brush
  • Apply body color with brush, roller, or sprayer
  • Work top to bottom to catch drips
  • Maintain wet edge to avoid lap marks
  • Apply full two coats for warranty and durability
10

Final Touch-Ups and Inspection

Walk through entire home and exterior inspecting all painted surfaces in different lighting conditions. Note any missed spots, drips, roller marks, or tape lines. Complete all touch-ups before final acceptance.

  • Inspect in natural light and with lights on at night
  • Check corners, edges, and trim lines for crisp edges
  • Look for drips, sags, roller marks, and holidays
  • Verify consistent sheen across each surface
  • Store leftover paint properly for future touch-ups

Paint Sheen Selection Guide

Flat/Matte

Zero sheen, hides imperfections, not washable.

  • Best For: Ceilings, low-traffic areas

Pro Tips

Use One Paint Line Throughout

Colors from the same paint manufacturer line are designed to work together. Mixing brands can result in colors that clash or look different than expected when viewed together. Pick Sherwin-Williams or Benjamin Moore and stick with it.

Box Your Paint

Pour multiple gallons of the same color into a large bucket and mix (called boxing) before starting. This eliminates slight color variations between cans that can show on large walls. Essential for consistent results.

Maintain the Wet Edge

Never let paint dry partially while painting a surface. Keep a wet edge and blend each section into the last. Dried edges create visible lap marks that are almost impossible to fix. Work quickly but carefully.

Quality Brushes Matter

A $15-25 Purdy or Wooster brush produces dramatically better results than cheap brushes. Quality brushes hold more paint, release it evenly, and leave smoother finishes. Clean and store them properly to last for years.

Remove Tape Before Full Cure

Remove painter's tape when paint is dry to touch but not fully cured (30-60 minutes). Fully cured paint may peel off with tape. Score tape edge with razor if leaving longer. Remove at 45-degree angle away from painted edge.

Test Colors in Actual Rooms

Colors look completely different based on lighting, adjacent colors, and room size. Paint large samples on actual walls - not just poster board. View at different times of day. What looks perfect at the store often disappoints at home.

Common Mistakes to Avoid

Skipping Surface Preparation

Preparation is 80% of a quality paint job. Painting over dust, loose paint, or unprimed surfaces causes peeling, poor adhesion, and visible imperfections. Never skip cleaning, sanding, priming, and caulking no matter how much you want to see color on walls.

Using Cheap Paint

Budget paint requires more coats, provides worse coverage, fades faster, and shows wear sooner. Premium paint costs 20-30% more but lasts 5-10 years longer and looks better. In a major remodel, paint quality is not the place to save money.

Applying Only One Coat

One coat never provides adequate coverage or durability regardless of what paint cans claim. Two coats ensure even color, proper film thickness, and maximum durability. "One-coat coverage" claims refer to hiding power, not quality results.

Painting in Wrong Conditions

Paint needs proper temperature (50-85F) and low humidity to cure correctly. Painting in hot sun causes bubbling. High humidity prevents drying. Cold temperatures prevent proper curing. Check weather forecast and plan accordingly.

Rushing Dry Time Between Coats

Applying second coat before first is fully dry causes lifting, peeling, and tacky finish. Allow minimum 2-4 hours for latex paint (longer in humid conditions). Better to wait overnight than risk ruining the job by rushing.

Frequently Asked Questions

What is the best paint sheen for interior walls?

Eggshell or satin finish is best for most interior walls. Eggshell provides slight sheen that is easier to clean than flat while hiding imperfections. Satin is more durable and washable, ideal for high-traffic areas and kids' rooms. Use flat/matte only for low-traffic areas or to hide wall imperfections. Use semi-gloss for bathrooms and kitchens.

How many coats of paint do I need?

Two coats of paint are standard for proper coverage and durability. The first coat seals and provides base color, the second provides depth and even finish. When changing from dark to light colors, use tinted primer plus two coats. Premium paints sometimes achieve coverage in one coat, but two coats always provide better durability and richer color.

Should I use Sherwin-Williams or Benjamin Moore?

Both are excellent premium paint brands with professional- grade products. Sherwin-Williams Duration, Emerald, and SuperPaint are top sellers. Benjamin Moore Regal Select and Aura are comparable quality. Choose based on color selection preference (Benjamin Moore has more nuanced colors) and local availability. Either brand far outperforms big-box store paints in coverage and durability.

How long should paint dry between coats?

Allow 2-4 hours between latex paint coats for touch-dry condition, but 24 hours for full cure before applying second coat is ideal. High humidity extends dry time. Temperature below 50F significantly slows drying. Oil-based paints require 24 hours between coats minimum. Applying second coat too soon causes lifting, poor adhesion, and uneven finish.

Do I need to prime before painting?

Prime when: painting new drywall, covering dark colors with light, painting bare wood, covering stains or repairs, switching from oil to latex, or painting glossy surfaces. Many premium paints include primer but still benefit from dedicated primer in these situations. Priming ensures proper adhesion and prevents bleed-through. Skip primer only when repainting similar colors on previously painted surfaces in good condition.
