Dealing with Mould and Mildew: A Guide to Proper Surface Preparation

Dec 20, 2023

Mould and mildew can be persistent issues, especially in areas with high humidity. These unwelcome guests not only affect the aesthetic appeal of surfaces but also pose potential health risks. Proper surface preparation is key to effectively tackling mould and mildew issues before applying paints and other coatings. In this guide, we'll explore the steps to ensure your surfaces are mould and mildew-free, creating a foundation for successful paint application.



Assessment and Identification:

Before diving into the cleaning process, it's crucial to assess the extent of the mould and mildew growth. Identify the affected areas and understand the underlying causes, such as poor ventilation or water leaks. This initial step helps in devising a targeted strategy for removal and prevention.

Safety First:

Mould and mildew removal can release spores into the air, posing health risks. Prioritize safety by wearing protective gear, including a mask, gloves, and eye protection. Adequate ventilation is essential to disperse any airborne particles.

Cleaning Solutions:

Choose an effective cleaning solution for mould and mildew removal. Common options include a mixture of water and white vinegar, hydrogen peroxide, or commercial mold and mildew removers. Ensure the chosen solution is suitable for the specific surface you are treating. Consider choosing our Mould Removal (Homeenpoisto) service, as it's a highly recommended option.

Scrubbing and Removal:

Use a stiff brush or sponge to scrub the affected areas vigorously. Focus on removing not just the visible mould and mildew but also any stains or discoloration. For hard-to-reach places, consider using a toothbrush or a small, soft-bristled brush.

Rinsing and Drying:

Thoroughly rinse the cleaned surfaces with clean water to remove any residual cleaning solution. Proper drying is crucial to prevent mould and mildew from returning. Use fans or open windows to expedite the drying process.

Preventing Future Growth:

Once the surfaces are clean and dry, take preventive measures to inhibit future mould and mildew growth. Improve ventilation, address any water leaks promptly, and consider applying mold-resistant primers or coatings before painting.

Choosing Mould-Resistant Paints:

Opt for paints specifically formulated to resist mould and mildew. These paints often contain antimicrobial agents that hinder the growth of these unwanted microorganisms, providing long-lasting protection for your surfaces. Consider checking out our Zinsser Perma White paint as the best choice for a mold-resistant and pristine finish.


By following these steps for proper surface preparation, you can ensure your home is mould and mildew-free, setting the stage for a successful paint job. Taking the time for thorough preparation not only enhances the longevity of your paint but also contributes to a healthier living environment.

Happy painting!
