Painting rooms with high humidity

Surfaces in rooms with high humidity must withstand exposure to water and detergents. It is necessary to protect such rooms from the appearance of mold and paint them so that they are easy to wash and wipe..

Remember:

-The wet room standard is divided into two classes: VN (waterproof surfaces) and VO (water-repellent surfaces).

-BH paint class is used for walls washed with water or for walls where splashing or leaks are possible. Areas where joints, joints and pipes pass through walls must be watertight.

-Examples of using the HV system: walls from floor to ceiling, in areas where bathtubs and showers are located, as well as walls located at a distance of 1 m from the above walls, if these walls are not protected by a dividing waterproof wall; on walls where water may leak from the tap connections.

-BO paint class is used on walls where splashing, wet cleaning, condensation or high humidity is possible.

-Examples of using the VO system: walls in washing rooms; walls located at a distance of 0.5 m from sinks in the kitchen or in the laundry room; walls in bathrooms and showers located at a distance of more than 1 m from the bath or shower area, if these walls are not protected by a dividing waterproof partition; walls at a distance of 0.5 m from sinks and toilets; ceilings in bathrooms, showers and similar rooms.

Maintenance instructions:

– In the early days, care must be taken with painted surfaces: let the surface dry for at least a week before using it or sprinkling with hot water.

– Washing is usually done with conventional synthetic detergents, from which peeling occurs, as they can damage the surface. Do not use alcoholic solutions (eg denatured alcohol) or strong solvents (eg white spirit), as these may dissolve the paint. Learn to flush the walls from floor to ceiling. Rinse the surface with clean water and dry it.

– Walls should be regularly cleaned of lime scale, soap and similar deposits. This is especially important for areas subject to such stress, such as showers and areas under the sink and tub. The sides and cut of the tub must be removed to clean the floor and walls. Use a soft brush and descaling solution when cleaning. Rinse the surface with clean water and dry it.

– If stains cannot be removed with synthetic detergents, try white spirit, which has a bleaching effect and can be a good stain remover or mildew stain remover..

– Check if there is sufficient ventilation and if it works well. Learn to use a rubber roller (dehumidifier) ​​to remove water from the floor. Draw your shower curtain and open the door a little. This will help reduce the humidity in the room and prevent mold from forming..

– Check that the insulation around the pipes is intact and that all screw holes are properly sealed. Always seal the screw holes and other holes as soon as they are made.
