How to get rid of condensation in your garage

Many garage owners are faced with such a problem as the formation of condensation inside. Moisture can appear anywhere: on the ceiling, gates, walls, cabinets, on the car itself. Our site will tell you about the causes of condensation in the garage and how to deal with it..

How to get rid of condensation in your garage

Our website has already written about the causes of condensation on the windows. Inside the garage, moisture can appear for similar reasons:

  • There is no ventilation or it is not done correctly;
  • Walls and ceiling are not insulated or insufficiently insulated;
  • Damp floor without waterproofing.

It’s simple – in winter it’s cold outside the walls of the garage, warm air comes from a heated car with a hot engine – that’s all, the ceiling and other surfaces began to “cry”. This has a very negative effect on the car, the body can begin to rust. Like other metal parts, tools, bicycles that are in the garage in equipped storage areas.

How to get rid of condensation in your garage

There are only two effective ways to get rid of condensation in the garage permanently:

  1. Provide reliable and constant ventilation;
  2. Insulate walls, ceiling, waterproof the floor and inspection pit.

First, let’s talk about garage ventilation. In our country SNiP 21-02-99 “Parking lots” operates. According to its standards, garage ventilation must provide a constant flow of fresh air in a volume of at least 180 cubic meters per hour per passenger car. According to foreign experts, at least six-fold air exchange should be provided in the garage. For example, for a garage with a volume of 60 m3 it will be 360 ​​m3/hour. These are serious requirements that in reality are often not met..

However, according to experts, even ventilation at the level of the garage itself can already save the room from dampness, and the car from rust. The main thing is to do everything right.

To ensure effective natural ventilation, the garage must have at least two openings:

  1. Supply air. Will draw in cold fresh air. Located above the ground, almost at the garage floor – at a height of 10-30 cm;
  2. Exhaust. It will remove warm, stagnant air from the room. It is located either on the wall, at a height of at least 1.5 m, or on the roof, at its highest point. In this case, the ventilation pipe must rise above the roof of the garage by at least half a meter..

It is important that both vents are on opposite walls, in a straight diagonal. For example, the exhaust outlet was equipped above the gate, then the inlet should be opposite, on the back wall, but below.

If there is a basement in the garage, a supply exhaust pipe is drawn into it. In this case, it is important that the entrance to the basement is sealed, and the pipe passes through the garage room and exits at ground level.

If natural ventilation is not enough, small electric fans can be installed in the existing openings.

But even this forced ventilation may not be enough to completely get rid of condensation in the garage. In this case, you will clearly have to do the insulation of the walls and ceiling..

Most often, garage owners save money and use polystyrene for insulation. Well, as an option. Do not forget to just blow out the cracks between the foam plates, if any, with polyurethane foam. Experts are confident that thermal insulation materials such as foam insulation and expanded polystyrene will become the best alternative, they are more modern and effective than foam..

Important! Experts do not recommend insulating a garage with mineral wool and other materials with a fibrous structure. They can get wet, lose their thermal insulation properties, which will only worsen the situation..

Don’t forget the gate. If they are too thin, just made of metal, it is advisable to sheathe them with thermal insulation from the inside..

Polyfoam or plates of other insulation are attached to the lathing; OSB, lining or plastic are often used as a finishing coating. If there is an attic above the garage, it is best to just pour a layer of expanded clay or brick chips there, this will warm the room well. Otherwise, you will have to mount the crate under the insulation and on the ceiling.

Before you start laying the insulation, be sure to dry the garage by installing heating devices in it. For example, a heat gun.

As for the floor, simple waterproofing in the form of bituminous mastic or roofing material, as well as concreting the entire surface, will avoid drawing in moisture from the soil.

Finally, we will give three tips that will help to avoid condensation in the garage, they will become additional preventive measures:

  • Do not heat the garage from time to time. You warmed up the room, yes, it became warm, the moisture evaporated. But as soon as the heating was turned off, and the frost outside, it will get even worse. The room will cool down, the condensate will quickly return;
  • The vehicle should cool slightly after driving. Only then close it in the garage;
  • You cannot put a wet, snow-covered car in the garage! Sweep the snow from the roof, wipe off the raindrops, and only then park the car and close the gate.
