When epoxy fails, it can often result in a messy and costly cleanup. Luckily, it’s only caused by one of two things: user error and product failure. So let’s make sure this doesn’t happen to you.

1. Poor Surface Preparation

One of the most common reasons why epoxy coatings fail is due to poor surface preparation. If the surface is not properly cleaned, degreased, and sanded before the epoxy is applied, the coating will not adhere properly and will eventually start to peel and flake off.

2. Incorrect Mixing Ratio

Another common reason for epoxy failure is an incorrect mixing ratio. Most epoxy coatings require a specific ratio of resin to hardener in order to cure properly. If the ratio is not precisely measured, the epoxy will not cure correctly and will eventually crack and fail.

3. Improper Curing

As stated above, the proper mixing ratio is essential when using epoxy. If the mixture is not properly done this will prevent the epoxy from curing properly. If the epoxy is not cured correctly, it will not reach its full strength. This can cause the epoxy to start degrading earlier and at a much faster rate, ultimately failing.

4. Incorrect Application

Since epoxy is a two-part adhesive that is mixed and then applied, the epoxy will start to harden and cure within minutes. Time is of the essence here, so it is important to work quickly when applying it. The epoxy should be applied in thin layers, and it is important to make sure that there are no air bubbles in the adhesive. If the epoxy is not applied correctly it will not adhere to a surface properly therefore resulting in peeling and flaking off.

5. Poor Quality Epoxy

Another reason for epoxy failure is due to poor-quality epoxy. There are many different types and brands of epoxy on the market, and not all of them are created equal. If you use a cheap, inferior-quality epoxy, it is likely to fail. Afterall, you get what you pay for!

6. Poor Storage Conditions

A common reason for epoxy failure is due to poor storage conditions. Epoxy is a sensitive material and can be damaged by extreme temperatures, humidity, and sunlight, especially if it hasn’t been cured properly. If the epoxy is stored in an environment that is too hot or too cold, it can degrade and eventually fail.

7. Environmental Factors

Epoxy failure can be attributed due to environmental factors. Since epoxy is a sensitive mixture it can be damaged by chemicals, UV radiation, and even water. If the epoxy is exposed to these elements, it can rapidly degrade and fail.
