Method for Fixing a Pitted Garage Floor
It may seem counter-intuitive for the concrete in your garage to begin to pit or crumble. After all, it is protected from the weather and not driven on as heavily as other concrete surfaces. Unfortunately, it is also exposed to road salts and standing water, particularly in areas with harsh winters. This leads to salt and freeze damage on the concrete surface, which then causes it to pit or crumble over time. The following guide can provide some repair ideas, along with techniques to keep it from happening again.
Uncover all the damage
Once pitting occurs, it will likely spread over much of the garage floor. After sweeping up the loose concrete, you can check the extent of the damage by tapping on the floor in various places with a hammer. If it sounds hollow, the concrete is damaged. For small areas, you can loosen and remove the damage by hitting hard with the hammer to shatter the damaged layer for sweeping up. For a larger area, a concrete service can grind or use shot blasting to remove the damaged surface layer.
Apply a patch
Covering the entire damaged area with a patching compound will prevent further damage. You have two options for patches—epoxy or polymer based. Epoxy-based patches are durable and easy to use but are only suitable for small areas because they do not have the structural integrity for a larger area. If you need to patch a large portion of the floor, opt for a polymer patch as these contain a sand aggregate that helps provide more structural integrity over a larger area.
Protect the floor
The patch will be visible, but adding a protective layer over it will solve this problem while also preventing future damage from occurring. The simplest way to protect the garage is to invest in heavy rubber garage mats. These protect the concrete from stains and damage, while also providing some insulation to make the garage more comfortable.
Another option is to seal and paint the garage floor. Garage floor paints come in a range of colors to fit any design choice. These paints provide a thick layer of protection so that stains and road salts won't soak into the concrete, while their color hides any patches that have been applied. To adhere well, the surface of the concrete and the patched area must be lightly ground down to roughen the surface so the paint sticks.
