Repairing Peeling Paint In Your Bathroom: A Quick Guide

If you're looking to fix paint that's peeling off in your bathroom, you've come to the right place. Paint peeling off walls is a common issue, especially in bathrooms due to the high levels of humidity and moisture. Before you start repainting, it's important to identify and address the cause to prevent the issue from recurring. This could be due to several factors, including inadequate ventilation, moisture buildup, or using low-quality paint. To resolve this issue, you'll need to start by removing the peeling paint and preparing the surface for a new coat. This involves scraping off loose paint, sanding the surface, and ensuring proper ventilation and airflow. Once the surface is clean and dry, you can apply a primer and choose a suitable paint designed for bathrooms, such as semi-gloss or gloss paint, which offers better moisture resistance.

How to fix paint that is peeling off in the bathroom

Scrape off loose paint

Paint that is peeling off in the bathroom can be unsightly and may even cause health issues if tiny flakes of paint are inhaled. Before you start scraping, ensure you lay a drop cloth down, especially if you will be using a chemical paint remover. It is also important to wear protective gear and ensure the room is well-ventilated when using chemical paint removers.

To scrape off loose paint, you will need a paint scraper, also known as a putty knife. Start by working the scraper in all directions to ensure that all the loose paint is removed. Be careful not to ding the wall underneath with the corners of your scraper. If there are any holes or gouges after scraping, patch the wall with joint compound or spackle.

If there are areas of paint that are difficult to remove, you can use a heat gun to loosen the paint's hold on the surface. Simply hold the nozzle of the heat gun about 2 inches away from the surface and sweep it back and forth. You can also use a paint stripper, applying it with a wide paintbrush or paint roller, to soften the paint before scraping.

For small or hard-to-reach areas, you can use a wire brush to smooth out the surface. If there are still some stubborn areas of paint remaining, you may need to use sandpaper or a sander to remove them completely. Be aware that this can be a time-consuming and labour-intensive process, especially if you are using sandpaper.

Sand the surface

Before you begin sanding, make sure you have removed as much of the old, peeling paint as possible. You can use a putty knife, a paint scraper, or even your fingernails to get all the loose bits off. It is important to start with a clean surface.

Once you have removed the peeling paint, it's time to sand the surface. For this step, you will need some medium-grit sandpaper. You want to sand the surface until it is smooth and even. Take your time with this step and make sure you get into all the nooks and crannies. If you have a large surface area to cover, you might consider renting a power sander or purchasing an affordable palm sander to make the job easier and quicker.

When sanding, be careful not to apply too much pressure, especially if you are working on drywall or softer materials. You want to avoid creating divots or damaging the surface. Work with a light touch and use circular motions to smooth out the surface evenly.

After sanding, it is a good idea to wipe down the surface with a damp cloth or vacuum the area to remove any remaining dust or paint particles. This will ensure that the surface is ready for the next step, which is priming.

Remember to take appropriate safety precautions when sanding, such as wearing a dust mask and safety goggles, to avoid inhaling dust or getting debris in your eyes.

Apply a coat of primer

After you've scraped off the peeling paint, sanded the area, and ensured that the surface is clean, it's time to apply a coat of primer. Primer is essential, especially in a humid environment like a bathroom, as it seals the surface, protects against moisture, and allows the paint to adhere properly.

Before you begin priming, ensure the area is well-ventilated. Open a window or switch on the ventilation fan. If you have a fan, make sure it's dust-free. If you don't have a fan, keep the window or door open during and after the process to allow any fumes to escape.

When choosing a primer, opt for one that is suitable for bathrooms, such as a mould-resistant primer. Zinsser, for example, offers a range of products specifically designed to tackle mould and peeling paint in bathrooms. You can also choose between quick-drying primers or those without volatile organic compounds.

Once you have your chosen primer, apply it evenly to all the problem areas. Follow the manufacturer's directions for drying time, and apply a second coat if necessary. Allow the primer to dry completely before moving on to the next step, which is applying a coat of paint.

By following these steps and applying a coat of primer, you'll create a smooth surface that will help your new paint job last longer and look its best.

Ventilate the bathroom

Ventilation is key to preventing paint from peeling in bathrooms. Bathrooms are the most humid rooms in the house, and moisture can get between the paint and the wall, breaking the adhesion. To prevent this, use an extractor fan or open a window during and after showering or bathing. If you use a fan, it should be a powerful one with a high extraction rate, and it should be left running for at least 10 to 15 minutes after you've finished. If you don't have an extractor fan, it is highly recommended that you install one. However, if this is not possible, opening a window will help to ventilate the room. Keeping the window open for 30 minutes after a bath or shower will help to clear the humid air and dry the moisture on your paintwork.

If your bathroom has a vent, make sure it is connected to a duct hose that vents to the outside. If your bathroom is in the basement or attic, make sure the duct goes through the roof, not the soffit. If your bathroom is uninsulated, it is more prone to condensation, and you may need to add insulation to prevent this.

Small dehumidifiers can also be used to lower ambient moisture levels. Keeping relative humidity below 50% will help to minimise condensation and its effects on painted surfaces.

Use a moisture-resistant paint

To prevent paint from peeling off in the bathroom, it is important to use a moisture-resistant paint. Bathrooms are constantly exposed to water and humidity, and the right paint choice can prevent mould growth, resist water damage, and maintain a fresh appearance for years.

Moisture-resistant paints can be made from a variety of bases. Acrylic paint, also known as latex paint, is a water-based material that is easy to clean and environmentally friendly. It is water-resistant and creates a strong, opaque finish. It is also quick-drying and resists fading and yellowing over time. When selecting acrylic paint, look for formulas for high-moisture areas, as these often contain additives that enhance their mould and mildew resistance.

Oil-based paints are another option for those seeking a water-resistant and abrasion-resistant base. They are great for providing a strong base coat that can withstand heavy condensation and high humidity.

When it comes to the finish, several options provide good moisture resistance. Gloss and semi-gloss finishes are specifically designed to resist moisture and will remain intact even with regular use. They create a hard, shiny surface that repels water and is easy to clean. However, some homeowners may not like the shine of these finishes, especially in smaller spaces. Satin finish paint offers a subtle sheen and a good middle ground between gloss and matte finishes. It provides good moisture resistance and is easier to clean than flatter finishes, but it is still challenging to spot-repaint.

When choosing a paint, it is important to read the label and ensure it is suitable for bathrooms. Many major paint brands have a special primer labelled for bathrooms, which is formulated to handle rooms with higher moisture. These primers usually have a mildew killer added and are designed to adhere to high-gloss surfaces.
