Bathroom paint should not be chosen at random. Due to its use, the bathroom is a rather special room of the house, often wet, which creates specific requirements. Discover the different types of paint that you can choose and their use.

SUMMARY

• Anti-humidity bathroom paint

• Anti-condensation bathroom paint

• Anti-mold bathroom paint

• Bathroom ceiling paint

• Bathroom tile paint

• Flaking bathroom paint

The bathroom paint must meet the conditions present in the room. In fact, you will have to choose a paint that resists both moisture and heat, but also offers protection against stains and mildew. This is especially true for areas close to water sources, such as the bath or shower and sink. For these walls, the paint must be leachable and not just washable. There are also paintings particularly suitable for certain materials, such as wood or metal, which can be used in some cases.

Once you have determined the needs of your bathroom, regardless of the quality of the wall to paint or repaint, some basic preparations are essential: the support must be as dry as possible, healthy, clean and dusted. And even if some walls do not always require underlayment, we will avoid painting directly without preparation and cleaning upstream. Thus prepare the walls by leaching the original paint and sanding if necessary to facilitate the adhesion of the new painting.

Long acclaimed as the benchmark bathroom paint, the glycerophthalic formula has a high resistance to moisture and can be leached. However, it also has a strong odor, takes longer to dry and contains solvents that make it toxic. It therefore tends to disappear gradually or to be replaced by glycerodified paints, usually mixed with water. The best solution is therefore to choose an acrylic paint for the bathroom. Less expensive and faster to dry, this category of paint is also more environmentally friendly and does not emit any odor. Perfectly suited to wet rooms, it can also contain fungicides and an anti-mold film, which help fight the scourge of moisture.

In the case of a healthy bathroom - that is to say, without a big problem of humidity - the walls that are not directly exposed to splashing water can be covered with a hydrophobic paint: its wax effect prevents water drops from getting inside the paint. The water stays on the surface.

Anti-humidity bathroom paint

In this case, we will implement curative rather than preventive actions, with paints adapted to the humidity problems encountered in the water body. The right "remedy" is to combine a moisture-proof undercoat with a moisture-resistant paint as well: the first one acts as a care by drying, insulating and preparing the water-damaged substrate, while the second, very resistant On the contrary, it will appreciate the moisture that may come from the inside of the wall, retain it and prevent the blisters from forming.

Anti-condensation bathroom paint

In case of thermal shock, there are also anti-condensation paints that reduce the difference between the hot air in the room - after a bath or a shower for example - and the cold wall. This technology consists of the presence of micro-glass beads that act as insulators, thus breaking the condensation.

Anti-mold bathroom paint

Other paints will prevent mold from developing, sanitizing the room and masking moisture-related stains. There are also treatments to be performed upstream, before repainting a bathroom, to permanently eliminate mold because, even after a large cleaning with bleach, it tends to reappear. An anti-mildew treatment product can also be applied to sealants, with greater efficiency than conventional detergents.

For a bathroom ceiling, use a moisture-proof paint, very closed, which will block the action of moisture.

Painting for a bathroom tile

In the case of tiled or earthenware bathroom a bit old, it is always possible to relook and paint on. Some brands of paint offer adapted products However, it is not recommended to use this type of products in case of stagnant water, on a shower wall for example. We will therefore repaint preferably a vertical tile: the apron of the bathtub and all other walls of the bathroom receiving little splash of water. So not the tiles in the shower cubicle or surrounding the bathtub!

An underlay is not needed but the rendering will be better with a double layer application. It is important to prepare the support: the tiles must be degreased, without traces of limestone and leached for a better hold of the paint. It is also important to respect the pause time between the two layers, usually 6 hours.

Flaking bathroom paint: what to do?

This condition of the bathroom siding is usually due to wear. At first, it is necessary to scratch the wall to put an end to the chipping, then to dust (possibly with a vacuum cleaner to be sure to remove everything well) and finally, to prepare and to paint the wall.
