Smooth Surfaces: 400-450 sq ft per gallon

Primer: 300-350 sq ft per gallon

Number of Coats Needed:

New drywall: 1 primer + 2 coats
Same color: 1-2 coats
Color change (light to dark): 2-3 coats
Color change (dark to light): Primer + 2-3 coats

Surface Preparation

New Drywall

Sand all joints smooth
Wipe down with damp cloth
Apply PVA primer
Light sand after primer dries

Previously Painted Walls

Clean walls (TSP or sugar soap)
Fill holes and cracks
Sand glossy areas
Spot prime repairs

Wood Trim

Fill nail holes with wood filler
Sand smooth (120-180 grit)
Clean dust thoroughly
Prime if bare wood or stain is bleeding through

Primer Selection

PVA Primer

New drywall, seals porous surfaces

Stain-Blocking Primer

Water stains, smoke, tannin bleed

Bonding Primer

Glossy surfaces, tile, laminate

Exterior Primer

Weather-resistant, UV protection

Tinted Primer

Dark color changes, better coverage

Painting Techniques

Cutting In (Edges)

Use 2-3" angled brush
Paint 2-3" band along edges
Maintain wet edge
Cut in one wall at a time

Rolling

Use 3/8" nap for smooth walls
Use 1/2" nap for textured walls
Roll in W or M pattern
Don't overload roller
Maintain wet edge

Spraying

Thin paint per sprayer instructions
Keep gun 8-12" from surface
Overlap passes by 50%
Keep gun moving, don't stop
Back-roll for better adhesion

Drying & Recoat Times

Paint Type	Dry Time	Recoat Time
Latex (Water-Based)	1 hour	2-4 hours
Oil-Based	6-8 hours	24 hours
Primer	1 hour	3 hours

Times vary by temperature and humidity. Cooler/humid conditions increase dry time.

Frequently Asked Questions

What paint finish should I use for bathrooms and kitchens?

Use satin or semi-gloss paint in bathrooms and kitchens because these sheens resist moisture and are easy to clean. Satin provides a soft sheen that hides minor imperfections while remaining washable. Semi-gloss is even more durable and moisture-resistant, making it ideal for areas that get wet or need frequent cleaning. Avoid flat or eggshell paints in these rooms as they absorb moisture and stain easily. For bathroom ceilings, use a mold-resistant paint formulated for high-humidity areas.

How much paint do I need for a room?

Calculate square footage by multiplying wall height by total wall width, then subtract windows and doors. One gallon typically covers 350-400 square feet on smooth surfaces. For a standard 12x12 room with 8-foot ceilings (384 sq ft of wall), you'll need about 1 gallon per coat. Textured walls require 20-30% more paint. Plan for two coats minimum - three if making a dramatic color change or painting over dark colors. Always buy an extra quart for touch-ups.

Do I need to prime before painting?

Prime new drywall (seals porous surface), bare wood (prevents tannin bleed), stained surfaces (blocks stains from bleeding through), glossy surfaces (helps paint adhere), and when making dramatic color changes (helps coverage). You can skip primer when repainting the same or similar color over paint in good condition. Use stain-blocking primer for water stains, smoke damage, or marker. Use bonding primer for glossy surfaces like tile or laminate. Tinting primer close to your finish color improves coverage.

How long should I wait between coats of paint?

For latex (water-based) paint, wait 2-4 hours between coats, though it's dry to touch in about an hour. Oil-based paint requires 24 hours between coats. These times assume normal temperature (50-85°F) and humidity. Cold or humid conditions significantly increase drying time. Don't rely on touch alone - paint can feel dry but not be cured enough to recoat. Applying the second coat too soon causes the paint to lift, drag, or show roller marks. When in doubt, wait longer.

What roller nap thickness should I use?

For smooth walls, use 3/8-inch nap for a light texture or 1/4-inch for ultra-smooth finishes. For textured walls or popcorn ceilings, use 1/2-inch to 3/4-inch nap to get paint into the texture. Thicker naps hold more paint but leave more stipple texture. For cabinets and trim where you want a smooth finish, use foam rollers or very short nap (1/4-inch). Always use quality rollers - cheap ones shed fibers into your paint and don't hold as much paint.

How do I avoid lap marks and brush strokes?

Maintain a "wet edge" - always brush or roll into previously applied wet paint before it dries. Work in sections you can complete before the edge dries (usually 3-4 foot sections). When cutting in, do one wall at a time and roll immediately after. Don't overwork the paint - once it starts to dry, leave it alone. Use quality brushes with proper bristle type (nylon/polyester for latex, natural bristle for oil). Load your brush properly and don't spread paint too thin. In hot weather, work in shade and consider paint additives that extend open time.
