If you’ve ever considered using a garage floor epoxy system to safeguard and improve the look of your car port floor, there are many things you have to know before purchasing one. Most home improvement stores carry epoxy floor products designed for the do-it-yourselfer and you might have heard differing opinions how well they work. Some will say it’s an excellent product as well as others will let you know not to squander your money. Well, there is certainly usually a simple explanation as to why this product fails for some floors.
One reason behind failure is don’t assume all concrete floor is suitable for making use of an epoxy coating. Many floors have too much hydrostatic pressure, meaning water movements from the under the slab up to the surface in an activity called capillary action. Moisture then gathers on the top, which breaks the connection between the concrete and the epoxy overcoat. If the floor “sweats” even when it’s dry exterior or there are areas that appear to stay moist for extended periods of time, then an epoxy layer will likely fail. It will little by little chip and flake away. Even if you don’t think there is a moisture problem, it’s wise to apply an efflorescence or salt blocker before the epoxy. This can help prevent dampness from causing problems.
The most probable reason for failing is incorrect surface preparation. The floor must be completely clean and stripped of most other coatings. Any stains or foreign chemicals (olive oil, grease, car paint, etc.) will prevent sufficient bonding between your concrete and epoxy, leading to chipping and flaking. Most contractors will apply a jacket of sealer to a garage area floor after installation. Normally it takes many years for the sealer to wear off completely. This sealer must be removed for epoxy to previous. Although acid etching can be an important step, it will not remove sealer and most stains. Etching will only open up the skin pores of bare cement, therefore you must do all cleaning and stripping before etching with acid solution.
Before investing in a garage floor epoxy system, you need to first decide if your floor is right for it. If it sweats often or there are areas that are constantly damp, then forget about it. Be sure that you are willing to take time to prep the floor properly, as this is the most critical part. In addition, it helps to put one or two jackets of clear concrete sealer at the top to serve as a wear coating. Water established acrylic sealers are perfect for indoor personal use. Despite any bad reviews you’ve found out about the do-it-yourself car port floor epoxy system, it can be a successful project whether it’s done correctly.
