Epoxy Floor vs. Painted Floor

What are the pros and cons of an epoxy floor?

One frequently asked question related to Epoxy Floors is: What makes your Epoxy Floor Coating systems better than just painting?


There are several factors that make KreteCoat Floor Coating Systems superior to standard paints.

A) First and foremost, we start every floor coating project with an extensive preparation process. A clean surface with a proper anchor profile is required in order to provide the proper foundation for a floor coating system.

We achieve this by performing the following steps:

  1. Removal of any surface contamination to meet SSPC - SP1 preparation standard (cleaning with a detergent if necessary).
  2. Diamond Grinding concrete to meet SSPC - SP13 preparation Standard for concrete. Grinding the floor removes any laitance (brittle cement) and creates a rough texture similar to 60 grit sandpaper. This texture gives the coating several points of contact to anchor down to. We use only the finest professional grade floor grinding equipment with diamond tooling selected for your specific concrete hardness. Our average grinder weighs over 600 lbs (compared to 100 lb models rented at Home Depot by our competition). This means that our equipment will cut deeper into the concrete achieving a far superior anchor profile. An industrial strength HEPA vacuum system will also be attached to the grinder while in use in order to control concrete dust disbursement. Our vacuums weigh 850 lbs and have enough suction power to pick up a bowling ball (not the standard shop vac you will see from our competition).
  3. A thorough vacuuming of the entire surface will then be performed in order to completely remove any remaining dust prior to applying any coating.
  4. The final step in Surface Preparation is to fill in all hairline cracks and divots using a 100% solid epoxy patch.

B) Another characteristic of a KreteCoat epoxy floor that makes it better than a painted floor is film thickness. For example, our standard Vivid Glass 2 Coat Epoxy Floor System has an average dry film thickness (DFT) of 20 mils or 20 thousandths of an inch. The leading floor and porch paint has a DFT of only 2 mils this means it would take 10 coats of porch and floor paint to achieve this thickness. That added thickness promotes impact resistance, insulation from thermal shock, and longevity.

C) Yet another reason to choose a KreteCoat epoxy floor over a painted floor is the fact that epoxy is simply tougher than Paint. Epoxy has over 3 times the compression, tensile, and bond strength of concrete. Most paints have only a fraction of the strength of concrete itself.
