Most local garages, especially privately owned ones and not part of a national chain/brand, are likely to exchange owners and property leases over a longer stretch of time. This could mean that youre looking to repair the garage floor for a sale, or from a purchase/new lease from the landlord.

Subject to high volumes of traffic, with cars, vans and motorcycles being wheeled in hour after hour, as a repair centre, the floor is likely to have seen the wars from chemical spills and leakages. There may be discolouration patches, UV exposure near the garage doors, or damage from toolboxes, ramp equipment and storage units. Moving forward, use mats under as much of the equipment as possible, to preserve the surfaces cosmetic structure.

Whilst floor paint can add a very good layer of protection against further damage, its purpose is not to fill or repair cracks and pitting. Concrete floor paints are generally slip-resistant, which is ideal for garages which conduct repair work, as cars may come in dripping wet from the rain or snow.

Keep your business foundation strong and repair any damage before a concrete floor replacement job needs a quote.

Start Fresh With A Resurfacing

Wear from vehicles, foot traffic, and the elements can turn into spider weblike craze cracking, flaking, or spalling, when the top layer of the concrete breaks off and exposes the patchy and pitted aggregate underneath. Luckily, any of these issues can be strictly cosmetic, as long as they are tended to soon after discovery. Ignore the early stages of spalling, however, and it could spread enough to compromise the integrity of the surface beyond repair.

A high-quality, professional resurfacing product like NewCrete Concrete Resurfacer from CTS Cement | Rapid Set addresses all of these imperfections in a single go. The cutting-edge product is self-curing, requiring no additional primers or products to finish the job after you coat your concrete floors. Best of all? Your garage wont have to be off-limits for too long Rapid Set NewCrete is ready for foot traffic after only two to three hours.

Age Or A Poor Installation Can Lead To A Garage Floor Replacement Or Repair

A garage floor replacement may be needed simply due to its age. A concrete garage floor slab should provide decades of use. Its not unheard of for slabs to last for a half century or more in some garages, however.

A poorly installed garage floor surface could be another reason your garage floor has seen better days. Some home builders cut corners and may not have done the following steps properly:

  • dug the garage floor sub base to the correct depth
  • used the proper concrete mix or used a high-quality cement
  • ensured the right compacting ratio was used so the ground/soil settles properly
  • placed the expansion joints in the proper locations
  • graded the garage floor correctly

Prep Your Garage Floor

Pitting on concrete garage floors usually doesnt extend more than ½ inch deep. After removing any broken or loose concrete, remove any oil stains, sealers, wax, or any bond-breaking material. Fill any holes with a dab of caulking or foam backer rod .

Caulking or a crack sealer can be used to fill any cracks in the surface. Place tape on each side of a crack before inserting filler material, so excess doesnt spread onto the rest of the floor, and use a putty knife or trowel to smooth it out. The tape can be removed when you complete this part.

Preparing The Concrete Floor For Repair

As with all repair work, from garden fences to flat roofs, preparation is key.

  • Using a chipping hammer, chip away at and removed loose, damaged and higher ridges of concrete around the repair site. Bigger scale damage areas may require an electric chipping hammer or a jack hammer.
  • Thoroughly clean the concrete surface with a stiff bristled brush, using a wire brush to help remove loose damage. When the surface is thoroughly brushed, you could use a vacuum cleaner to remove any smaller particles and dust thats left.
  • Using a professional cleaner and degreaser will remove impacted oil and grease from the floor, prior to further repair and resurfacing work.

Repairing Spalled And Pitted Garage Floors

Pitting of a garage floor can be caused by improper finishing of the concrete or a bad mix. Sometimes it is most notable at the edges of contraction joints or where the concrete might meet up with another slab.

However, spalling is generally caused by freeze-thaw cycles in colder climates. It is aggravated even more by deicing salts. Pitting can be a result of this as well.

During cold weather, water can migrate into the surface of the concrete and freeze. The expansion of the water causes microscopic damage to the concrete and after a few years of this, it begins to break up into small dusty pieces and flake or chip away.

For repair of the floor, you will want to use an epoxy sand slurry or a polymer-modified cement patching mix. Which type you use depends on the extent of the repair. It requires a little more effort than repairing a crack, but its not that hard to do.

After the surface has been prepared properly, you apply the mix over the pitted areas using a trowel. Some mixes are self-leveling and can be applied with a metal squeegee.

Be sure to feather-in smooth and let it cure according to the instructions. You may need an additional application to fill in any small divots or low spots you missed.

You should end up with a nicely repaired surface that wont be noticeable once it is painted or epoxied over. We cover this procedure in more detail, including recommended materials, in our article on how to repair spalled or pitted concrete.

Prepare The Surface By Cleaning And Sanding

The first step to repairing your peeling epoxy garage floor is to prepare the surface. This means cleaning it thoroughly and sanding it down so that the new epoxy will have a smooth surface to adhere to. If there are any cracks or holes in the floor, youll also want to fill these in with a concrete patch before proceeding. Once the surface is prepped, you can begin applying the new layer of epoxy.

Apply A Primer To The Floor

After the floor is clean and dry, the next step is to apply a primer. This will help the new epoxy adhere to the floor and prevent peeling. There are two types of primers that can be used for this project: an etching primer and a self-leveling primer. Etching primer should be used if the floor is not level. Self-leveling primer can be used if the floor is level.

For best results, follow the manufacturers instructions when applying primer. If using etching primer, apply it with a brush or roller and make sure to evenly cover the entire surface. If using self-leveling primer, pour it onto the floor and spread it evenly with a brush or roller. Once the primer is dry, youre ready to move on to step three.

Penetrating Sealer Blocks Concrete Pores And Stops Crumbling

In any case the use of a penetrating sealer is essential to block the pores in the concrete. Penetrating sealers are silicon based compounds such as silanes, siloxanes, silicates & siliconates. These are clear low viscosity liquids that can be applied to the garage floor with a low pressure spray.

Silanes work the best with concrete garage floors. They will penetrate into the concrete, react chemically within the capillaries to block them, but will not form any film on the surface.

Due to their small molecule size, Silanes are frequently used for sealing pre-cast concrete and high performance concrete such as: parking garages, bridge decks, building facades, and concrete forms.

Repair methods for these problems include patching and resurfacing.

Repair Deep Cracks And Depressions

If the vacuum has sucked out deep cracks that leave sizable voids, use non-shrinking concrete patch to fill these areas. Concrete patch is available both in premixed tubs and in caulk-gun tubes for application. Use a pointed trowel to force the patch material down into the crack to completely fill gaps.

Allow the patching cement to fully dry and cure before proceeding. For most products, this requires about 24 hours.

Look For These Telltale Signs Of Structural Issues:

Replacing a NOT professionally installed epoxy garage floor. Acid etching failed…AGAIN
  • When the crack is bulging out of the floor, thats a sign that the foundation has shifted and contracted a bit, pushing up the bulging area. This is something that a professional can evaluate.
  • Erosion of the floor can be another sign that theres a deeper structural issue.
  • When the cement on one side of your crack is lower than the other side of the crack, the crack is likely due to the ground beneath shifting and a structural issue.

Regarding the last sign above, one side below your floor had more wiggle room than the other side, and eventually the floor couldnt support its own weight anymore, and one side cracked then shifted lower.

When this gets really severe, there are companies who can shoot material below the floor to raise-up the part thats sunk, its not cheap but its a really good way to fix this type of issue.

Granted, most of this happens very slowly. If youre in a climate where the temperature varies a lot, for example somewhere with hot, dry summers and cold, freezing winters, this can help amplify and speed up the spread of damage, but even at that, it can take years for it to go from noticeable to bad.

When To Call A Professional For Cracks In A Garage Floor

Before we get into specifics on how repair cracks in garage flooring, lets go over a few examples of when youll want to call in a professional for help instead of taking the DIY route.

Getting a professional to fix these types of cracks early can lead to less long-term damage, and the sooner you get it sorted out, the better.

Generally speaking, there are cosmetic cracks and cracks that appear as a sign of structural issues. Cosmetic cracks look bad, but thats about it – they arent a sign of a greater problem. Theyre isolated, and once theyre fixed youre all set.
