5 Common Mistakes To Avoid When Applying Epoxy

Epoxy is a type of adhesive known for its super strong joining properties. Besides this, it is one of the most durable and versatile adhesives, making it ideal for all types of minor and major projects. In addition, epoxy provides a strong resistance to heat and chemicals.

Hence, you can use it in places with high temperatures, and it will still do its job without any hassle. Therefore, you can use the adhesive on any surface, such as glass, metal, wood, fabric, plastic, and many more. However, people often make mistakes while applying epoxy, which can cause many problems.

Keeping this in mind, we have listed the five common mistakes to avoid when using epoxy and how to optimise the adhesive to your advantage. So, without further ado, let’s proceed to the next section.

5 Common Mistakes To Avoid When Applying Epoxy

1. Not Following Humidity and Temperature Guidelines

When it comes to epoxy, most manufacturers provide specific guidelines to follow for humidity and temperature. In general, epoxy shouldn’t be applied at low temperatures since it may not harden or cure properly. Moreover, extremely hot temperatures can reduce the pot life of the adhesive to half.

On that note, epoxy doesn’t function correctly since the high temperatures create bubbles, indicating outgassing. Apart from this, applying epoxy in a highly humid environment is not recommended. It can cause the formation of microscopic layers on the surface.

Due to this, the epoxy starts to peel off from the surface. Therefore, you should thoroughly follow the manufacturer’s guidelines to see the best results.

2. Faulty Floor Preparations

Most professionals prefer to use epoxy for installing garage floors; however, epoxy can be a bit tricky during this process. Poor floor preparations can often result in bad finishes and epoxy floor failure. Fisheyes are yet another problem that may occur when oil is on the surface. Nevertheless, you can avoid this problem if you follow our advice carefully.

First and foremost, epoxy doesn’t adhere well to smooth surfaces. The same can be said if the surface has a layer of wax, oil or other forms of contamination. Additionally, the adhesion requires open pores on the surface to show its best results. Hence, we suggest acid etching or grinding the concrete before applying the epoxy to the surface.

3. Moisture Present On The Concrete

While working with concrete, it is important to ensure it is dry before applying the epoxy. Usually, it is recommended to let the concrete dry for at least 24 hours after performing acid etching on the surface. However, you might need to wait longer if the temperature and humidity levels keep fluctuating in your surroundings.

Besides this, we advise performing a moisture test to ensure the surface is completely dry. Otherwise, the trapped moisture will create hydrostatic pressure. This will cause the epoxy to peel off and chip pieces of concrete. That’s why some manufacturers produce water-based epoxy that can work well with damp surfaces. Get in touch with your local manufacturer and find out if the epoxy is water-based or not.

4. Don’t Stretch Out The Epoxy

One of the most common mistakes people make while applying epoxy is that they stretch it out too much. This usually happens when people fall short of the adhesive and want to avoid paying extra money by stretching the epoxy beyond its threshold. This mistake results in a weaker coat since the epoxy doesn’t spread out evenly.

Ideally, if you have a 500 square feet floor, you should purchase an epoxy kit that offers coverage of at least 600 square feet. Also, you should avoid using a cheap single-coat epoxy paint kit since it leaves the surface less glossy and unevenly discoloured.

5. Avoid Faulty Mixing

Lastly, try not to mix the epoxy incorrectly since this will raise problems while applying. For instance, using the paddle mixer too fast can trap air within the epoxy. Therefore, these air bubbles will create an uneven finish while applying the adhesive to the surface.

Instead, you should slowly move the paddle mixer and monitor it carefully to prevent air bubbles from forming. Additionally, following the right mixing ratio for the resin and hardener is recommended.

Installing Epoxy The Right Way

In simple terms, epoxy is an excellent adhesive to work with as long as you avoid the common epoxy application mistakes above. Due to strict regulations when preparing epoxy, it is rare to find bad epoxy. It is still important, though, to spend some time researching and preparing your surface before applying the epoxy for the best results.

Then again, applying epoxy without professional help can be tricky. So to get the best results from your coating material, entrust the application process to the experts and give Top Coat Concrete a call in Sydney.

That said, it’s a wrap. See you next time!
