Seal the garage floor - what you must pay attention to

A garage is not moisture free. By walking and especially by the parked, wet vehicle is always moisture and moisture in the garage. It is certainly not wrong to worry about the proper sealing of the garage floor. What you have to pay attention to, you can read here in detail.

Moisture and resulting problems in the garage

In and of themselves, concrete floors are not particularly sensitive to small amounts of moisture. The problem here are other parts of the garage. In some cases, these include the sidewalls.

Concrete also has difficulties with de-icing salt. The salt-wet vehicle, which is parked in the garage, repeatedly dripping very salty water on the concrete, which can thereby damage over time.

base sealing

The garage floor itself can be - if necessary - easily sealed by an epoxy resin coating. Such coatings can be applied cost-effectively even. As a rule, they are also completely resistant to de-icing salt and thus protect the concrete from damage in the long term.

In addition, such coatings effectively avoid stains and oil traces that are difficult to remove from untreated concrete.

However, the problem is always the sealing of the base or the surrounding masonry. Again, a seal should take place. If screed is laid in the garage, the screed joint must also be sealed accordingly.

Here, a technically correct seal is essential. Every seal on the screed joint must be frictionally locked, even in the garage, as otherwise a lot of water can penetrate these areas later and be pulled up in the brickwork. The garage will be wet.

As a rule, a so-called hollow scoop joint is used for the sealing, which is complex in terms of craftsmanship but is indispensable in practice. In other cases, the use of special profiles may be sufficient.

It is advantageous to also coat the lower wall base with the coating when using epoxy resin coatings. This not only helps to create a better look but also provides effective moisture protection at the bottom of the wall.

Sealing with liquid foil

Films made of liquid plastics can also be used for sealing. In practice, however, they are rarely used in the area of ​​garage floors. Coatings are cheaper and more effective and also provide better protection against stains in the concrete.

Tips & Tricks

Silicone joints are not always completely sufficient in the floor area, even if they are made often.
