Wall Painting FAQs (2025): Coats, Finishes & Techniques

Whether you’re painting your home for the first time or refreshing your walls, you probably have questions like: How many coats of paint do I need? Is primer necessary? Should I brush or roll?

This guide answers the most common wall painting FAQs in Kenya (2025) to help you achieve a flawless finish.

How Many Coats of Paint Do Walls Need?

• Interior walls: 2 coats for best coverage.
• Exterior walls: 2–3 coats, depending on surface condition.
• Dark colours: May need 3 coats to cover evenly.

👉 Always allow the first coat to dry fully before applying the second.

Is Matte or Eggshell Better for Walls?

• Matte Finish: Smooth, non-reflective, hides imperfections, but less washable. Best for ceilings and bedrooms.
• Eggshell Finish: Slight sheen, more durable, easier to clean. Best for living rooms and hallways.

👉 For Kenyan homes, eggshell or silk finishes are most popular.

How Many Coats of Emulsion Paint Are Needed?

Typically two coats of emulsion are enough for even coverage. A third coat may be necessary for deep colours or rough walls.

Is It OK to Paint Over Old Paint?

Yes — but only if the old paint is in good condition:

• Clean the wall thoroughly.
• Lightly sand glossy surfaces.
• Fill cracks and holes.

👉 If the old paint is peeling or flaking, scrape it off before repainting.

Is It Okay to Paint Without Primer?

• For new walls: Primer is highly recommended for good adhesion.
• For repainting: If the wall is already painted and in good condition, you can skip primer.
• For dark-to-light colour changes: Use primer to reduce extra coats.

What Paint is Best for Skirting Boards?

Use oil-based gloss or enamel paint for skirting boards. These paints are tougher, easier to clean, and resistant to scuffing.

Is It Better to Brush or Roll Paint?

• Brush: Best for edges, corners, and small areas.
• Roller: Best for large, flat wall surfaces — faster and smoother coverage.

👉 Professional painters use both together for the best finish.

What Happens If You Put Too Much Paint on a Wall?

• Uneven drying → streaks or bubbles.
• Paint drips and sagging.
• Longer drying time.

👉 Apply thin coats and build up gradually.

Do You Need to Sand a Wall Before Painting?

Yes, light sanding helps paint stick better and creates a smooth finish. Especially important for glossy or uneven surfaces.

Do Professional Painters Spray or Roll?

Both methods are used:

• Spray painting: Faster, smoother, best for large projects.
• Roller painting: More controlled, less messy, best for homes.

Is It OK to Paint Over a Dirty Wall?

❌ No. Dirt, grease, and dust prevent paint from sticking properly.
✅ Always clean walls with mild soap and water before painting.
