How to Prep Your Garage for an Epoxy or Polyaspartic Floor
How to Prep Your Garage for an Epoxy or Polyaspartic Floor
If you're planning to upgrade your garage floor with a professional epoxy or polyaspartic coating, the success of the job depends on one critical step: proper prep.
At 585 Epoxy Solutions, we’ve seen it all—coatings that failed because the surface wasn’t ready. Whether you're doing it yourself or hiring a pro, here's what every Rochester homeowner needs to know about prepping a garage floor before installation.
1. Clear Out the Space Completely
We know it’s a pain—but for a flawless install, your garage needs to be 100% empty.
That includes:
Cars and bikes
Lawn tools and bins
Shelving close to the ground
If we’re handling the job, we’ll coordinate with you for ideal timing and offer advice on short-term storage.
2. Deep Clean the Surface
Any dirt, grease, oil, or stains can prevent the coating from bonding properly.
We recommend:
Sweeping or vacuuming loose debris
Degreasing oil spots with a concrete cleaner
Avoiding bleach (it can interfere with adhesion)
Our crew will still clean and mechanically prep—but a solid base makes a difference.
3. Repair Major Cracks or Pits
While our process includes grinding and filling, it helps to identify areas of concern:
Visible cracks or spalling
Soft or crumbling concrete
Water intrusion around the slab
We'll assess these during your quote and include repair in the system we apply—especially with older Rochester garages.
4. Moisture Matters
Before coating, we check for moisture vapor emission. Why? Because trapped moisture under a coating can lead to bubbling or failure.
We use a simple test (plastic sheet or moisture meter) to check if your concrete is dry and ready to coat.
5. Surface Grinding = Key to Bonding
Whether you're getting epoxy or polyaspartic, proper mechanical grinding opens up the concrete and ensures the coating soaks in and grabs hold.
At 585 Epoxy, we use industrial diamond grinders to etch and clean the surface—far beyond what a DIY etching kit can do.
6. Don’t Just Sweep and Paint
This is where many DIY kits go wrong. Simply cleaning and rolling on a coating without proper prep usually leads to:
Peeling
Bubbling
Yellowing
Total system failure within 1–2 years
If you want a garage floor that lasts 10–15 years, prep is the foundation.
Epoxy vs Polyaspartic: Does Prep Differ?
Not really—both coatings need the same thorough surface prep. The main difference is in:
Cure time (polyaspartic is faster)
Flexibility & UV resistance (polyaspartic wins here too)
Prep for either system needs to be done right the first time to ensure long-term performance.
