100% Solids Epoxy Is A Bad Idea For An Epoxy Garage Floor
By the very nature of the name 100% solids epoxy, you should be able to tell that it’s pure epoxy, and therefore it doesn’t penetrate the concrete substrate. 100% epoxy merely attaches to the “grooves” or texture created in the concrete, if the floor is properly prepared by scarification or shotblasting. Diamond grinding is not a good means of preparing a floor for a 100% solids epoxy floor. See (Floorex-Concrete Preparation Guide).
As the guide shows only the most aggressive grinding even begins to get you in the range of (CSP 3-7) where you should be for 100% solids epoxies. Diamond grinding and installing 100% epoxy flooring would need a 6 grit diamond grinding to be on the low side of the chart, and basically a minimum of the standards set forth.
100% solids are ideal for heavy wear areas where forklifts and multi-ton vehicles will be using them heavily and repeatedly for years and years. 100% solids epoxy coatings are older technologies, and are fairly soft when compared to polyureathane and polyasparic coatings used today, and are applied thick, so the wear does not go through them over the years of heavy traffic causing an epoxy floor failure.
The biggest problem with 100% solids in a garage floor application is that when moisture does get through the concrete, as it breathes, the bond with the grooves can break and cause a catastrophic failure where the epoxy will bubble, and peel off in large pieces, resulting in the need for a complete epoxy floor replacement.
Never install 100% epoxy on your garage floor! When you combine the fact that 100% epoxy does not penetrate into the concrete (only attaching to the grooves and texture created by shotblasting or scarifying the concrete), and the lack of a moisture barrier in garages, it’s easy to see why this is a bad idea for most epoxy garage floors!
- 100% epoxy floors need shotblasting or scarification for the preparation
- 100% epoxy does not penetrate concrete pores
- 100% epoxy floor failures are catastrophic in nature (no little repairs possible)
- No moisture barrier installed in most residential garages
- Say NO all the time to 100% epoxy in your homes garage
If you do install 100% solids epoxy in your garage without the proper preparation or moisture barrier, you could be looking at a complete failure and replacement of your epoxy garage floor. At SealKC we only apply 100% solids epoxy in the right conditions and in commercial setting with proper moisture barriers and testing. Typically we use water based primers and epoxy to penetrate into the concrete and allow concrete to breathe for a long lasting garage floor.
While it is possible to install a 100% solids epoxy floor in a Kansas City area garage, when you take into account all the extra precautions and labor needed, it is not usually a viable choice for a residential garage floor. Insist that epoxy moisture barrier or primers are installed as well as concrete moisture testing if you are considering such a floor, and be aware that these steps will cost and drive up the total call of the garage floor installation.
Don’t make a huge mistake and have 100% solids epoxy installed in your garage!
