Why is my garage floor so dusty?

Posted on: July 31, 2020 by Dencroft Garages

We know that garages are so much more than just a place to park your car. At Dencroft Garages, weve seen customers transform their garage space into anything from home gyms and home offices to mancaves and even just a great storage place. But if your garage is always dusty, it can spoil the fun. Read on to find out what you can do to eliminate the dust.

What causes a dusty garage?

One main cause of dust is the components that make up concrete. If these get out of balance, the concrete will degrade faster than it should, and weak concrete can create dust.

Other dust culprits include:

  • Debris and material such as leaves breaking down
  • Pet fur
  • Hair
  • Dead skin

What causes concrete to dust?

If you have a bare concrete floor in your garage, there are some factors that might cause dust.


Moisture from water, oil spills or chemicals can all start to break the surface of your concrete floor down.


Concrete can expand and contract slightly with changes in heat. This can be a problem particularly in colder weather.


Physical contact with the concrete surface from everyday use such as driving your car in or walking across the floor can start to wear it down.

How do I get rid of garage dust?

To get rid of existing dust, you might need to give your garage a good clean. Use a dust cloth to wipe down any surfaces where dust has settled and pay particular attention to the walls and floor of your garage. Use a vacuum cleaner if you can instead of a sweeping brush to avoid the dust spreading around the space.

If you use your garage for storage and have a lot of stuff in there, its a good idea to set aside some time to declutter your garage before you begin cleaning so that theres less dust and less areas for dust to cling to.

How do I prevent a dusty garage?

Dust builds up quickly even after a thorough clean, so we recommend maintaining your garage and using a concrete coating to seal the surface. Properly sealed concrete should prevent the excess dust in your garage.

For extra protection, you might also consider fitting a door seal to help prevent debris from being brought into your garage.

Dust is a problem for many of us and youll never completely eradicate it but following these steps should make a big difference and allow you to start enjoying your concrete garage again.
