Tools & Materials

Trade Tips

  • Use a really good quality paint brush and roller
  • Don’t use haphazard strokes when using a roller. Use long even rolling strokes.
  • Add Mold and Mildew inhibitor to the paint
  • Between coats of paint, place your roller and brush in separate plastic bags and tie the bags at the top. This stops the roller and brush from drying out.
  • Wash your brushes outside on the grass. Don’t wash them in the sink, it’s not good for the environment.

The How To

Step 1

Lay out the drop sheets to cover floor, vanity etc. making sure you cover all surfaces. You don’t want to get paint on surfaces like benchtops, cabinets, taps or floors which will then need to be cleaned off.

 

Step 2

Add the mold and mildew inhibitor to your paint. Check the bottle, (manufacturer instructions), for the amount to add as it varies depending on the quantity of paint you’re using. 

 

Note: Premixed paints containing mold inhibitor for bathrooms are available. These are convenient but they can be more expensive. If you want to save, buy separately and add the inhibitor to the paint yourself.

 

Step 3

Apply the blue painters tape to all the edges where the wall meets the ceiling. The purpose of Painters tape is to let you ‘cut in’ the straight edges without getting paint onto the adjacent surfaces. The tape is designed to release easily without damaging the surface.

 

You’ll achieve a nice straight finish and save time cutting in if you’re not painting the walls.

Step 4

Using a paint brush and nice long, even strokes, ‘cut in’ all the areas you won’t be able to paint with a roller.

 

Step 5

Apply paint to the roller, via the tray, and paint the ceiling using long even strokes.

 

Don’t push down too hard on your roller as it can create lines between strokes. When the paint dries, the excess paint that created the line will be evident – and you don’t want that.

 

Step 6

Leave paint to dry for 2 hours before starting the second coat.

Step 7

Apply second coat, repeating steps 4 to 6.

 

Step 8

When you’ve finished painting and paint is totally dry,  carefully remove the blue painters tape and clean up.

 

Step 9

Clean brushes and rollers, using a hose, outside on the grass. Don’t wash brushes out in the sink.

Note: If the bathroom ceiling is being painted for the first time, a sealer undercoat with a mold inhibitor should be applied as a first coat to the bare cornice and plasterboard.

How to Stop Bathroom Ceiling Peeling

Unfortunately if paint is already peeling on your bathroom ceiling it’s not an easy fix. This is because you’re dealing with someone else’s poor workmanship.

 

Why is the paint peeling?

The surface hasn’t been prepared correctly in the first instance. A Sealer was not used on the bare plasterboard as the very first coat.

 

What’s the solution?

Option 1 

You can try scraping off the paint from the entire ceiling and then follow the steps below.

 

Option 2

Sometimes it’s just easier to resheet the ceiling and properly prepare the bathroom ceiling from the beginning using a sealer undercoat, with a mold inhibitor, and then follow up with semi-gloss paint with inhibitor.

Option 1 : What you'll need

Step 1

Scrape paint.  It will be messy, so lay out drop sheets on the floor. Note: All paint must be thoroughly removed.

Don’t forget the protective eyewear and a dust mask.

 

Step 2

Check for mold and wash ceilings with a mold killer if needed. Allow to completely dry.

 

Step 3

If there’s any damage to the ceiling from removing (scraping) the paint, replaster the affected areas to achieve a smooth surface finish. And then sand.

 

Step 4

Reseal the ceiling with a mold inhibitor sealer undercoat. Follow up with 2 coats of semi-gloss with mold inhibitor.

Important

If the paint isn’t completely removed, it won’t matter what paint you apply, you’ll probably find paint will start peeling in another area of the ceiling within a short time.

Q&A's

A semi-gloss paint with a mold inhibitor.  This paint provides protection from peeling and moisture and is easier to clean. Having a mold & mildew inhibitor additive offers more protection against mold in a damp room.

Semi-gloss paint with added mold and mildew inhibitor

For general areas a flat ceiling paint because it hides imperfections on the joins.

I prefer to use a semi-gloss paint for bathroom ceilings. Mold & mildew tends to grow quicker on flat paint and it’s harder to clean.

Use a product that is a mold-remover and follow the instructions. It’s very important to make sure the area is well ventilated when using these products and use a face mask when applying.

 

I like Dulux products because they are strong, durable and easy to use. However there are many excellent brands on the market.
