Painting the bathroom following a procedure and with a bathroom painting you need to use the right paint.

When painting a bathroom, you have to take into account that a lot of moisture is released during a shower.

The moisture splashes often come against the walls and ceiling.

Painting the bathroom with ventilation

It is then the main thing that you regularly ventilate.

This is good for your humidity in your house.

If you do not do this, the chance of bacteria is very high.

You then grow mold in your bathroom, as it were.

When you place double glazing, make sure that you always put a grid in it.

If there is no window in the bathroom, make sure you place a grille in the door in combination with mechanical ventilation.

Make sure that this mechanical ventilation remains on for at least 15 minutes from the moment you turn off the tap.

This way you avoid difficulties.

If you want to seal any seams that connect to the tile work, always use a silicone sealant.

This one repels water.

So the conclusion when painting a bathroom: plenty of ventilation!

The bathroom is of course the most humid place in your home. That is why it is extremely important that the walls and ceiling are sufficiently resistant to water load. This can be done with the right bathroom paint. You can read exactly how you do this and what you need for it in this article.

Buy a multimeter, a practical and safe purchase

What do you need?

You don’t need much for this job. It is important that everything is clean and undamaged, and that you use the right paint. That is, paint that is suitable for damp areas. Below you can read what you need:

  • Soda solution (soda and a bucket of warm water)
  • Wall filler
  • Coarse sandpaper grit 80
  • Quick-drying primer
  • painter’s tape
  • Wall paint for damp rooms
  • voltage seeker
  • stiff brush
  • wide putty knife
  • Narrow putty knife
  • Soft hand brush
  • paint bucket
  • paint grid
  • wall paint roller
  • Round acrylic brush
  • Possible plaster repair

The step-by-step plan

  • Before you start painting the bathroom, turn off the power. Then you check with a voltage tester whether the power is really off. you can then remove the cover plates from the sockets.
  • Do your bathroom walls have an old coat of paint and is there mold on it? Remove this first with a strong solution of soda and warm water. Use a stiff brush and scrub it well. Isn’t all mold gone? Then sand this away with coarse sandpaper grit 80.
  • After this it is time to look at any damage to the wall. If there are, you can update them with a suitable filler. You can apply the filler with a narrow putty knife. By sweeping it over or into the damage in a smooth motion.
  • After you have allowed this to dry sufficiently, you can sand it with a coarse sandpaper with grit 80. After this, make the walls and ceiling dust-free with a soft brush.
  • Then tape all floor and wall tiles, pipes and bathroom tiles with painter’s tape. You should also mask off other parts that do not need to be painted.
  • Now we will first apply the primer, but this is only necessary if you have not painted the bathroom before. It is best to use a quick-drying primer for this, which dries within half an hour and can be painted over after three hours.
  • After the primer has dried, we can start painting. Start with the edges of the wall and any hard-to-reach areas. This is best done with a round acrylic brush.
  • After you’ve done all the edges and difficult spots, it’s time for the rest of the ceiling and walls. For smooth surfaces, it is best to use a short-haired paint roller. Does your bathroom have a textured surface? Use a long-haired paint roller for best results.
  • When you start painting, it is best to divide the walls and ceiling into imaginary squares of about one square meter. Apply two to three passes with the roller in the vertical direction. Then you also divide the layer horizontally until you have an evenly covering whole. Overlap the imaginary squares and roll all the squares again vertically when you’re done. Work quickly and do not take a break in between. This prevents a color difference after drying.
  • Let the paint dry thoroughly and then see if you find the layer opaque enough. Isn’t that the case? Then apply a second coat. Check the packaging of the paint carefully after how many hours it can be painted.
  • It is best to remove the painter’s tape immediately after painting. In this way you prevent that you accidentally pull pieces of paint along or that ugly glue residues remain behind.

Additional tips

  • You would do well to buy enough paint, rather too much than too little. On the cans of paint you can see how many square meters you can use with one blister you can paint. Do you have an unused can left? You can then return it within thirty days.
  • Do you have a plaster or spray plaster layer and can you see damage in it? The best way to fix this is with a plaster repair.

Paint the bathroom with an anti-fungal latex

It is best to paint a bathroom with a water-based anti-fungal wall paint.

This wall paint absorbs moisture and repels moisture.

This prevents your wall from peeling off.

Do not forget to apply a primer latex beforehand.

This primer ensures good adhesion.

Apply at least 2 coats of latex paint.

You will see that the drops of water slide down, as it were, and do not penetrate the wall.

What is a very important point is that you apply the latex on a dry wall.

The humidity should be less than 30%.

You can use a moisture meter for this.

You can buy these online.

Another thing I want to warn you about is the fact that you should never apply latex that is suitable for outdoor use.

This latex seals out more moisture than the above wall paint.

Once again I would like to point out that you always ventilate well while showering.

Painting a shower cubicle with a 2in1 wall paint

There are many products on the market that make it easier for you.

There is also a product from Alabastine.

It is a mold-resistant wall paint that has been specially developed for places that are often more humid and therefore more prone to mold

You don’t need a primer for this.

You can apply the wall paint directly to the stains.

Very handy!
