Tips for Painting Moisture-Prone Areas

Aug 22, 2023Richard Weager

Battling with moisture-prone areas within homes is a common issue in the UK. The wet, steamy, and moist environment can wreak havoc on walls and ceilings, causing paint to peel and leading to unattractive mould and mildew growth.

This article provides a comprehensive overview of moisture-resistant paint. We’ll also reveal expert tips and techniques for preparing and painting your surfaces to protect moisture-laden areas in your home.

Understanding Moisture-Prone Areas

Moisture-prone areas are typically spaces in your home with high exposure to water or humidity. In many homes, these areas include the kitchen, where steam from cooking can accumulate, and bathrooms, where daily showers create a consistently moist environment.

Other areas that are also considered high-risk for moisture are cellars and external walls that are regularly exposed to damp weather.

Identifying Moisture-Prone Areas

Recognising these moisture-prone areas is the first step in tackling the issue. Watch for early signs of dampness, such as musty smells, traces of mould or mildew, or staining on walls and ceilings. Peeling or bubbling paint can also indicate an underlying moisture problem. All these signs suggest areas that could significantly benefit from a protective layer of moisture-resistant paint.

Benefits of Moisture-Resistant Paint

Moisture-resistant paint, also called anti-mould paint, offers several advantages in combating dampness. By creating a protective layer on the surfaces, this special type of paint can shield your walls and ceilings from the adverse effects of moisture. Here are some key benefits:

  1. Prevents the growth of mould and mildew: Mould and mildew not only cause stains but can also affect the air quality in your home, leading to potential health issues. Moisture-resistant paint contains specific additives that prevent mould from growing.
  2. Enhances paint durability: Moisture-resistant paint is formulated to withstand a damp environment. This extra resilience increases the lifespan of your paint job, ensuring your walls and ceilings look fresh and well-maintained for a longer period of time.
  3. Improves aesthetics: By providing a barrier against dampness, moisture-resistant paint helps maintain the original colour and finish of your paintwork. This gives your rooms a consistently clean, fresh look, enhancing the overall aesthetic of your living spaces.

Choosing the Right Moisture-Resistant Paint

Your paint selection can significantly impact the long-term durability and visual appeal of your moisture-prone areas. Both mould-resistant paint and mildew-resistant paint are specially formulated to withstand humid conditions and are excellent options for these areas.

Understanding Paint Finishes for Moisture-Prone Areas

The finish of your paint, whether gloss, semi-gloss, satin, or matt, plays a critical role in its performance in damp conditions. Gloss and semi-gloss finishes are typically recommended for moisture-prone areas due to their durability and easy-to-clean nature. Their shiny surfaces are not only more resistant to humidity but also tend to resist the growth of mould and mildew better than matt finishes.

Bathroom Paint

Selecting a moisture-resistant paint tailored for specific rooms in your home can further protect your home from mould. Bathroom paint is specially designed to handle the high humidity and frequent temperature fluctuations common in bathrooms.

Kitchen Paint

Kitchen paint, on the other hand, is formulated to resist grease and grime and is typically easier to clean. This is crucial considering the frequent messes in this area of the home.

Surface Preparation

Proper surface preparation is paramount to achieving the best possible finish and longevity from your paint job. Taking these additional steps will ensure maximum adhesion and waterproofing.


First, clean the surface thoroughly. Use a suitable cleaning solution to remove any mould, dust, or loose paint flakes. Ensure the surface is free from grease – especially in the kitchen, as this can impact paint adhesion.

Repairing Cracks or Leaks

Fill any cracks or holes with a high-quality filler and allow it to dry completely before sanding the surface smooth. Use a waterproof sealant to fix any leaks, and let it dry before painting.


Sand the surface to create a rough texture that will help the paint adhere. Use fine-grit sandpaper and sand in a circular motion, being careful not to over-sand the surface.


A primer creates a smooth surface for the paint, increases its adhesion to the wall, and provides an additional layer of protection against moisture. Using a mould-resistant primer can give you an even higher level of protection.

Applying the Paint

After proper preparation, you’re ready to apply the moisture-resistant paint. This can be done using a brush or roller, depending on the size of the area and the type of surface. Apply the paint in even strokes or rolls to achieve a consistent finish.

We recommend applying at least two coats of paint to ensure optimal coverage and protection. Remember to allow the paint to dry completely between coats to avoid stickiness and peeling.

Additional Painting Tips for Long-Lasting Results

A few additional measures can ensure the longevity of your paint job in moisture-prone areas:

  • Choose the right paintbrush: A high-quality paintbrush is essential for achieving a smooth, even finish. Look for a brush with synthetic bristles that can handle the thickness of moisture-resistant paint.
  • Apply the paint in thin layers: Thick layers of paint may dry unevenly and peel off over time. Apply the paint in thin, even layers for a better finish.
  • Ventilation: Ensuring your space is well-ventilated helps reduce moisture levels. Install extractor fans in kitchens and bathrooms, and ensure cellars have proper air circulation.
  • Regular maintenance: Regularly inspect your painted areas for any signs of wear or damage. Early detection allows for quick touch-ups, maintaining a fresh and clean look.
  • Use waterproofing sealants: Waterproofing sealants offer an extra layer of protection against moisture. This is particularly useful in exceptionally damp areas or where direct water contact occurs.


Through using moisture-resistant paint, opting for the correct finish, and preparing surfaces adequately, you can create attractive, resilient spaces. With the right knowledge and techniques, any room can stand strong against dampness, retaining its beauty over time.

At Greenshop Paints, a moisture-resistant paint we recommend for interior walls is AURO Anti-Mould Paint. It’s breathable, solvent-free, and has a higher pH to prevent mould growth.
