Why Floors Peel: The Most Common Reasons & How We Prevent Them

When someone gets a coated garage or basement floor, the last thing they expect is peeling or bubbling. But it happens - and most of the time, it comes down to just a few simple reasons. The good news? They can be prevented when the floor is installed the right way.

Here are the most common causes and how we avoid them.

1. Moisture Moving Through the Concrete

Almost every concrete slab has some level of moisture inside it - especially older floors, softer concrete, or homes built on hills or areas that naturally hold water. You may not see moisture on the surface, but it can still be there.

The challenge is that moisture becomes noticeable after the floor is sealed. Once a coating goes down, the vapor has nowhere to escape, which can lead to peeling.

How we prevent it:
In our most commonly recommended system, we use epoxy primers that sink deeper into the slab and help manage moisture vapor. It creates a stronger foundation for the entire system.

2. Not Matching the System to the Concrete

Every slab behaves differently. Some need more moisture support, some don’t. Some are brand-new, others decades old. A coating system should be chosen based on the concrete itself - not a product name or a one-size-fits-all approach.

How we prevent it:
During your quote, we look closely at your slab and explain which system fits your environment and concrete conditions.

3. Surface Not Prepared Correctly (Grinding + Vacuuming)

Proper prep is one of the biggest factors in whether a floor lasts.
The concrete has to be:

  • Ground to the correct profile

  • Cleaned thoroughly

  • Free of dust, debris, and loose particles

If dust is left behind - even a thin layer - the coating won’t bond correctly.

How we prevent it:
We grind the entire floor, repair cracks, and vacuum thoroughly to make sure the surface is completely clean before we install anything.

4. Floors Installed Too Quickly

Some systems are designed to move fast, but speed doesn’t always mean the concrete was ready. Skipping steps or rushing the process can create long-term issues.

How we prevent it:
We follow a step-by-step process based on what your concrete actually needs, not how quickly the job can be finished.

5. Environmental Factors That Affect the Cure

Temperature, humidity, and even the location of your home all influence how a coating cures. Cold floors cure slower (sometimes turning a one-day system into two), while heat and humidity can speed things up too much. Shaded areas, moisture-heavy spots, and older concrete also impact how well a coating bonds. If timing or conditions aren’t adjusted, the coating may not cure the way it should.

How we prevent it:
We always check the environment, temperature, and slab conditions before starting, then adjust our timing and product choices so the coating cures properly. This ensures the floor bonds and hardens the way it’s designed to.

6. Wrong Mixing/Ratios

Floor coatings rely on two parts being mixed together correctly so they can cure and bond the way they’re supposed to. If the ratios are off, if the product isn’t mixed thoroughly, or if it sits too long before being applied, the coating may not harden properly - which can lead to soft spots, weak areas, or peeling later on.

How we prevent it:
We follow exact mixing ratios, scrape the sides and bottom of the bucket so everything blends evenly, and only mix what can be used within the proper working time. This ensures the product cures the way it was designed to.

Our Approach Before We Recommend Any System

Before we recommend any system, we don’t just look at a color chart and guess. We walk you through the whole process so you understand exactly what your floor needs and why.

Here’s what that looks like:

  • Step 1: Reach Out
    You call us or submit a quote request, and we get a little basic info about your space and what you’re hoping to do with it.

  • Step 2: Schedule a Walkthrough
    We set up a day and time to come out, see the space in person, and make sure we’re giving you accurate recommendations - not just ballpark guesses.

  • Step 3: On-Site Visit
    During the walkthrough, we:

    • Look closely at the condition of your concrete (age, softness, cracks, previous coatings, etc.)

    • Consider whether moisture may be present or could become an issue

    • Take photos and measurements

    • Ask how you plan to use the space (home gym, garage, workshop, playroom, basement, etc.)

    • Talk through your goals, concerns, and timeline

  • Step 4: Go Over Options Together
    We explain:

    • Which primer makes the most sense for your slab

    • The system we’d recommend (and why)

    • Prep, installation steps, and what to expect during the process

    • Color, flake, and finish options

You’ll know exactly what we’re planning to install, how it works with your concrete, and why it’s the right fit for your space - not just a system pulled off the shelf.

This way, you’re not just getting a price; you’re getting a plan that’s built around your concrete, your goals, and how you actually use the space.

If you’d like us to take a look at your floor and walk you through the best options, we’re always here to help.
