Epoxy floor coating is the best garage flooring options on the market for its durability, beautiful shine and low level of maintenance.

One common phrase Vision Seal hears from customers “Our floor application has done already, but the epoxy paint is peeling off the concrete garage floor.”

What many people don’t realise is that 90% of these complaints are not due to a defective epoxy product.

It is interesting to note that the majority of complaints about epoxy garage floors are from DIY applications.

The reason being is that the average DIY installer usually does not have the required skills to apply Epoxy.

When you add this to the fact that most of the inexpensive epoxy floor kits make application sound as natural as rolling paint on the floor, you have a recipe for failure. 

Why does Epoxy peel off?

Epoxy is a very tough coating to remove when appropriately applied.

Therefore, when applied correctly, Epoxy can last decades.

The truth is that just about every epoxy problem is avoidable by paying attention to the details. 

  • Poor surface Profile

A poorly prepared concrete is the main reason for the Epoxy to peel off the pavement.

  • Quality of concrete floor prep.

Another step of the concrete preparation, which many DIY installers skip, is the proper cleaning of the concrete floor before applying the Epoxy.

The floor must be clean and free of oil, grease, loose dust and debris.

When grinding the concrete, dust and loose debris cover the concrete.

If there are any oil, silicone and tire polymer residue, you need to grind your floor rather than use acid etching.

The acid will not remove any oil stains or clean heavy grime off of concrete.

Acid needs to react with the free lime in the concrete to work.

If there is a thin film of oil or dirt on the surface, the acid will not work.

  • Moisture Buildup Underneath Coating

When laying your brand new epoxy floor, you need to make sure your concrete is arid.

Moisture under the concrete slab can cause pressure that forces the Epoxy to separate from the concrete’s surface.

If your concrete slab is brand new, you need to wait at least 28 days to before you apply Epoxy thoroughly dry.

If you’ve chosen acid etching as a floor preparation, you need to wait at least 24 hours before proceeding with the Epoxy. Otherwise, the moisture trapped in the concrete’s pores will rise and cause bubbles in the floor finish.

  • Acid etching residue

Many DIY kits on the market, recommend acid etching for floor preparation.

The reason being is that it’s cheaper and more accessible than concrete grinding. However, acid etching has a lot of disadvantages.

For a start, acid etching products use citric acid, due to being environmentally and user-friendly.

The way the acid works is by reacting with the free lime in the concrete.

This results in a breakdown of calcium on the surface and exposing the concrete pores.

Calcium is then deposited onto the surface, forming a thin layer of dust.

As mentioned before, this dust needs to be effectively removed.

Otherwise, the Epoxy will stick to the dust rather than the floor. Also, acid etching does not remove oil, grime and sealer from the surface.

  • Sealed Concrete Floor

As mentioned before, Epoxy needs a clean and porous concrete to create a mechanical bond.

If your concrete has been previously sealed, it needs to be firstly ground before applying Epoxy. 

This removes the sealer and gives you the correct surface profile.

If you are not sure if your concrete has been previously sealed, you can test it with water, spread around different areas of the concrete.

If the water turns dark and is absorbed into the concrete, it means your concrete is free of a sealer. 

  • Not Enough Epoxy

DIY epoxy floor kits generally won’t cover many garages.

Moreover, a prepared concrete floor will absorb some of the epoxies.

If you have a 40 square meter garage and you buy a kit that says it covers 30-50 square meters, you will run out.

If you try to stretch the product to cover your floor completely, the result can be an epoxy coating that is too thin or not hard enough.

This will decrease its durability and longevity. In the long run, you will end up re-applying the Epoxy a year later.

Preventing your epoxy floor from peeling

Applying Epoxy can be tricky.

To ensure durability, longevity and a beautiful finish of your epoxy floor, you need to ensure that the concrete floor is prepared correctly and that the environmental conditions are between 10 – 35 degrees.

Here at Vision Seal, we believe that prevention is the best cure.

If it might seem like you are saving a lot of money, by doing it by yourself, but in the long run, it will prove more expensive.

Even that DIY epoxy kits make an Epoxy sound like a walk in the park; if not done correctly, your Epoxy will be peeling and cracking within a year.

If saving money is what you are looking for, Vision Seal’s advice is to hire a professional to do the job for you.

This way you’ll have a beautiful epoxy garage floor, that will last you for decades, without having to worry about it.
