Bathrooms are the most humid rooms in any home. Steam from hot showers and poor ventilation create the perfect environment for mould to grow. That’s why painting a bathroom isn’t as simple as painting any other room. It requires planning, the right materials, and the correct technique.
If you’re planning to repaint your bathroom, you may wonder how to keep it looking fresh and mould-free for years to come. The good news? You don’t need to be a professional painter to do a great job. You need the proper steps.
In this blog, you’ll learn how to paint your bathroom correctly and avoid mould problems. Whether you’re a DIY lover or planning to hire bathroom renovation contractors near me in Melbourne, this guide will help you make the right choices.
Why Mould is a Big Problem in Bathrooms
Mould isn’t just ugly—it’s also unhealthy. It can cause respiratory problems, allergies, and even structural damage if left untreated. Bathrooms are especially vulnerable because:
- Moisture builds up quickly.
- Poor ventilation traps steam.
- Bathrooms are often painted with the wrong type of paint.
The key to stopping mould is to reduce moisture and use the right materials that resist it.
Choose the Right Paint
Not all paints are made for bathroom use. Regular paint may look good at first, but it will peel, crack, and attract mould over time. Here’s what to look for:
- Moisture-resistant paint: This type of paint is designed to handle high humidity.
- Mould-inhibiting properties: Many bathroom paints come with built-in mildew-resistant formulas.
- Semi-gloss or satin finish: These finishes repel water better than flat paint.
A Melbourne painting company can guide you in selecting the right product if you’re unsure.
Prepare the Bathroom Properly
Preparation is the secret to a successful paint job. Before opening a paint can, ensure your bathroom is prepared.
- Clean Thoroughly
Remove any signs of mould with a mix of bleach and water (1 part bleach to 3 parts water). Scrub all surfaces, including walls, ceilings, and corners. Rinse and let dry completely.
- Remove Old Paint
If the existing paint is flaking or stained with mould, scrape it off. Use sandpaper to smooth the surface.
- Repair and Patch
Fill in holes, cracks, and damaged spots with spackling paste. Sand smooth once dry.
- Prime the Surface
Always use a mould-resistant primer. This creates a protective barrier, which helps the new paint adhere more effectively.
Ventilation is Key
No paint will stop mould if your bathroom isn’t ventilated properly. Make sure you:
- Use an exhaust fan during and after showers
- Open windows regularly
- Keep the bathroom door open after use.
If you’re working with painters in Kew, ask if they can install a fan or recommend other solutions.
Use the Right Tools
The right tools make your job easier and the results more professional:
- Use a high-quality roller for large surfaces
- Use a brush for corners and edges.
- Consider painter’s tape to avoid messy edges.
If you don’t have the tools or time, a trusted Melbourne painting company can get it done faster and cleaner.
Apply Paint Like a Pro
Even if you use the best paint, poor technique can lead to streaks, peeling, and mould.
- Use Thin, Even Coats
Don’t apply too much paint at once. Use two thin coats instead of one thick one.
- Let Each Coat Dry
Follow the manufacturer’s instructions for drying time. Don’t rush!
- Focus on Humid Areas
Pay extra attention to the ceiling, behind the toilet, and around the shower or tub. These are mould hot spots.
Paint the Ceiling First
Many people forget to paint the ceiling, but it’s one of the most common places for mould to grow. Use mould-resistant paint and consider a bright white finish to reflect light.
Painting the ceiling first also prevents drips from ruining freshly painted walls.
Seal the Edges
Once the paint is dry, seal around windows, sinks, and tubs with waterproof silicone caulk. This blocks water from seeping behind walls and causing hidden mould.
Some bathroom renovation contractors near me in Melbourne include sealing as part of their service, so don’t skip this critical step if you’re hiring help.
Keep It Dry
After painting, change your habits to prevent future mould. Here are a few tips:
- Wipe down wet surfaces after each use.
- Use bath mats that dry quickly.
- Avoid hanging wet towels in the bathroom.
Routine cleaning and ventilation will protect your paint job for years.
When to Call Professionals
Not everyone has the time or skill for a DIY bathroom paint job. If your bathroom has serious mould issues or needs repair, it’s best to work with experts.
Professional painters in Kew know how to prep, paint, and seal bathrooms correctly. They use commercial-grade mould-resistant products and ensure clean results with no mess.
Likewise, bathroom renovation contractors near me in Melbourne can handle larger updates, including waterproofing, tiling, and repainting.
Conclusion
Painting a bathroom without worrying about mould is all about preparation and the right materials. Select the correct paint, prepare the surfaces correctly, and ensure your bathroom is well-ventilated. If you follow these steps, your bathroom will stay fresh, bright, and mould-free. Remember, you don’t have to do it alone. Hiring a reliable Melbourne painting company or trusted painters in Kew can save time and deliver long-lasting results.
