How to Fix Common Wall Painting Problems: Expert Solutions

Painting your walls might seem like a simple task, but many homeowners quickly discover that getting a flawless finish takes more than just a brush and a tin of paint. From peeling paint to uneven coverage, wall painting issues are frustrating—but they’re also fixable.

In this blog, we’ll explore common wall painting problems and how a Painter and Decorator or a Professional Painter would tackle them. Whether you're tackling a DIY job or considering expert help, understanding these solutions will save you time, money, and stress.

1. Peeling or Flaking Paint

Problem

Paint that starts to peel or flake usually indicates poor surface preparation or moisture issues.

Expert Solution

A Professional Painter will:

• Scrape off the loose paint

• Sand the surface until smooth

• Check for damp patches or leaks

• Apply a quality primer before repainting

Avoid painting over damp or dirty surfaces, as this will only worsen the problem.

2. Paint Bubbling

Problem

Bubbles or blisters on painted walls form when the paint loses adhesion and lifts off the surface, often due to heat, moisture, or painting over dirty walls.

Expert Solution

A seasoned Painter and Decorator would:

• Identify the source of moisture or heat

• Remove the bubbled paint using a scraper

• Smooth the area with filler and sand it down

• Apply primer and repaint with suitable paint for the environment

For bathrooms or kitchens, moisture-resistant paints are best to prevent recurrence.

3. Uneven Coverage or Patchy Paint

Problem

Uneven paint coverage happens when too little paint is used, or when the roller or brush quality is poor.

Expert Solution

A Professional Painter ensures even coverage by:

• Applying a tinted primer to even out the base

• Using high-quality tools like rollers with appropriate nap

• Applying multiple thin coats rather than one thick coat

• Allowing each coat to dry fully before applying the next

Professionals often cut in carefully and roll walls systematically for consistency.

4. Roller Marks and Lap Lines

Problem

These occur when one section of paint dries before the next is applied, leading to visible lines or streaks.

Expert Solution

A Painter and Decorator would:

• Maintain a wet edge while painting

• Paint in small sections from top to bottom

• Use ‘W’ or ‘M’ motions for better distribution

Also, using the same batch of paint throughout the job prevents colour inconsistencies.

5. Paint Cracking or Crazing

Problem

Cracks appear when paint dries too fast, is applied too thickly, or is incompatible with the previous layer.

Expert Solution

To fix cracked paint, a Professional Painter will:

• Sand down the affected area

• Remove flaky bits

• Apply a flexible primer

• Use paint suitable for the surface and conditions

In older homes, underlying issues such as movement in the walls may need to be addressed before repainting.

6. Mould or Mildew Stains

Problem

Dark patches or streaks on walls, especially in humid rooms, are signs of mould or mildew.

Expert Solution

Professionals handle this by:

• Treating the area with an anti-fungal wash

• Repainting with mould-resistant paints

• Improving ventilation in the room

While painting over mould might hide it temporarily, the underlying issue needs fixing to prevent return.

7. Fading Paint Colour

Problem

Wall colours fade over time due to exposure to sunlight, poor-quality paint, or chemical reactions.

Expert Solution

A Painter and Decorator will:

• Choose fade-resistant, UV-stable paints

• Recommend specific finishes like satin or eggshell for longer colour retention

• Apply a fresh topcoat to bring walls back to life

North-facing walls and areas with consistent light exposure need extra attention when selecting paint.

8. Greasy or Stained Walls

Problem

In kitchens or high-traffic areas, grease and stains can bleed through fresh paint.

Expert Solution

A Professional Painter tackles this by:

• Cleaning the walls thoroughly with degreasers

• Sealing the area with a stain-blocking primer

• Repainting with washable and scrubbable paint formulas

This ensures longevity and keeps walls looking fresh for longer.

DIY or Hire a Professional?

While many of these problems have DIY solutions, hiring a Professional Painter can save you both time and costly mistakes. A Painter and Decorator brings experience, the right tools, and product knowledge that guarantees a high-quality finish.

They also offer advice on the best products to use for your wall type, lighting, and room function—ensuring long-term satisfaction.

Final Tips for a Perfect Finish

• Always prep your surface: clean, dry, and sanded.

• Choose the right paint for the room’s use.

• Invest in good tools—cheap brushes can cost you more in the long run.

• Don’t rush the drying process between coats.

• If in doubt, call a Professional Painter to get the job done right.

Wall painting problems can quickly turn a home improvement project into a headache. But with a little know-how—and the help of a trusted Painter and Decorator—these common issues are easy to fix. Whether you're battling peeling paint or streaky finishes, expert solutions are always within reach.
