Condensation on the floor in a private house

It often happens that condensation appears in residential and non-residential premises on ceilings, walls and floors. It can be a kitchen, bathroom, loggia or other room. This dampness penetrates deeply and first destroys the decorative finish, and after that - the base of the surface, it negatively affects things and products that are in the room, and also negatively affects the well-being, and in severe cases, the health of residents. This phenomenon must be fought and not with the consequences, but with the reasons from which it appeared. We will understand why condensation appears on the floor in a private house, as well as walls, and how to deal with this problem.

Condensate

If warm, humid air enters a cold surface, such as a wall or floor, condensation forms. It appears mainly when the street has a low air temperature and high humidity. To determine what you are dealing with - condensation or penetrating moisture, you need to put a small piece of foil on a damp surface and glue it with tape on the edges. If, after two days, moisture has come out from above, it is condensation; if from below, it is penetrating dampness.

Most often, condensation on the wall in the apartment appears in the kitchen and in the bathroom, where the cooking process, washing, washing.

Reasons for the appearance:

1. The main reason condensation appears is a violation of generally accepted building rules and norms during the construction of the entire building.
2. Condensation on the floor in a private house appears, most likely due to the freezing of building structures. Moisture can come from blowing and melting snow, if the walls and foundation of the house have cracks.
3. Poor room heating.
4. High humidity due to poor ventilation.

Condensation removal on the floor in a private house

It is possible to eliminate condensation on the floor in a private house, which appears due to freezing. But first you need to find out which way the freezing occurs - through a wall, floor or foundation:

• If the reason is in the wall, then it must be insulated. Only external insulation will give a positive effect.

Important! Do not save money on the thickness of the insulation. Can be used for this purpose:

• Styrofoam;
• mineral wool;
• liquid insulation.

• If the reason is in the foundation, and it is most likely concrete, then insulate it with extruded polystyrene foam, its thickness should be at least 5 cm. Cover the top with a thin-layer facade plaster reinforced with a plastic mesh. It is necessary to dig out the foundation if the house does not have a blind area and insulate the underground part to the depth of freezing. With a pile-grillage or pile foundation, it is necessary to disassemble the pick-up and fill it with insulation.

Important! It is highly likely that the foundation itself is the reason why condensation appears on the floor in a private house.

Ways of floor insulation

Warming only one floor will not completely solve the problem, but will most likely be only an additional measure. There are two options for insulation - cosmetic and capital. Let's consider both in more detail.

Cosmetic

This type is less effective, but also easier. To carry out it is necessary:

• Remove the flooring, lay at least 6 mm thick polyethylene foam or cork sheets on the base.
• Install a high baseboard around the perimeter of the exterior walls.

Important! Be sure to lay insulation between the wall and the baseboard.

• If there is no heat-insulation-deformation tape between the wall and the base of the floor, then it is necessary to cut the joint with a grinder, insert a strip of extruded polystyrene foam or foamed polyethylene into the resulting strip.

With the correct elimination of the problem of freezing of external structures, additional floor insulation may not be necessary.

Capital

This option will significantly increase the floor level:

• For its implementation, it is necessary to lay the insulation on the base or pour cement-sand screed.
• You can also put a rigid foam glass and fill it with a layer of level.
• You can lay on the lags and plank floor, while warming them. This is a laborious process that will take time and effort.

Important! How to perform major repairs by arranging an environmentally friendly plank floor - for detailed instructions, see the article "Installation of a wooden floor on the logs".

Condensation elimination on walls

To eliminate condensation on the walls in a private house or apartment, you need to get rid of the reasons for its appearance:

• High humidity.
• Poor thermal insulation.

Moisture elimination

The problem of increased humidity indoors is the problem of insufficient ventilation. To solve this problem, you need to put the hood in the kitchen over the stove, and in bathroom mount exhaust fan.

Important! In old apartment buildings, the access ventilation shafts are clogged with dust, debris, debris of concrete and brick. Management companies are obliged to take measures to bring these mines to working condition.

You can reduce the increased humidity in the room by observing practical tips:

• When cooking, open the window or window, close the doors to the kitchen.
• Ventilate the bathroom after taking a shower while washing and drying it.
• Do not dry wet clothing in a residential area.

Thermal insulation troubleshooting

Basically, condensation on the wall in an apartment or a private house, as well as other rooms, appears not because of our mistakes, but because of the poor quality or lack of thermal insulation of the walls and ceiling.

To solve this problem, if we are talking about a private house, its basement or garage, laborious and expensive, but possible. If we are talking about an apartment in a multi-storey building, then there is no way to completely eliminate the problem, we can only reduce the risk of these negative consequences. For this, it is necessary to produce external or internal wall insulation.

Important! External insulation - more effective!

To eliminate the problem of condensation, it is necessary to dismantle the old design of the thermal insulation system and install a new one. Also, the cause of condensation can be eliminated by constant ventilation of the premises, because dampness and fungus are afraid of fresh air.
