  1. Selecting the wrong epoxy products

Some DIYers complain of not getting desired results. The main reason for this problem can be choosing the wrong epoxy product.

There is a wide range of epoxy products available in the market. Hence, selecting the best epoxy product can be challenging. You need to carefully read the details written on the label of your epoxy product. You also need to read the exact thickness usage to avoid various problems during the work.

  1. Over and under mixing

The mixing ratio of epoxy must be precise. Usually, the mixing ratio of resin and hardener is between 1:1 or 2:1. You can find the exact mixing ratio on the packaging of the epoxy resin. Make sure to read the label of the epoxy resin.

  1. Inappropriate temperature

The epoxy applied on the countertop surface can not be cured if the temperature of your room is inappropriate. The room temperature should be between 70 to 75 Fahrenheit to get good results. If the temperature is too cold or hot, your epoxy will get hardened.

  1. Wrong Measurement

Epoxy comes in two different containers. One has resin, and the other has a hardener. You need to measure both resin and hardener correctly to avoid common epoxy problems. You can find the correct measurement volume on the containers of resin and hardener.

  1. Using dirty tools

Some DIYers complain that the epoxy surface is not giving a glossy and shining look as they expect. The reason behind this problem can be the use of dirty buckets, sticks, and mixing containers. To avoid this problem, use tools that are clean of any dirt for applying the epoxy.

  1. Dull and cloudy epoxy surface

Excessive moisture can make the epoxy dull and cloudy. You can avoid this problem by removing all water before applying the epoxy. The room moisture should be between 50% to 60% before pouring the epoxy. Room moisture above 75% is not suitable for epoxy coating.

  1. Unlevel epoxy

By default, most epoxy resins are self-leveling. But you may face the problem of leveling the epoxy properly. You can fix this problem by waiting until the epoxy dries and applying another coat of epoxy.

  1. Appearance of bubbles

The problem of air bubbles on the surface of the epoxy countertop is common. Sometimes, it becomes hard to remove the bubbles. However, there are various methods you can try. The heat gun is one of the most effective methods to remove air bubbles. However, don’t flame the epoxy surface for more than 3-4 seconds.

  1. Micro holes on the epoxy surface

Sometimes, micro holes can appear on the epoxy surface. You can fix this problem by filling pits with resin with the help of a spatula. Let the surface dry, then apply another coat of epoxy resin on it.

  1. Sticky patches on the surface

Some DIYers face the problem of sticky patches on the epoxy surface. The one reason for this problem is the use of expired epoxy products. To fix this problem, use epoxy products within one year from the date of manufacture.

  1. Bubbles in the epoxy mixture

Air bubbles in the epoxy mixture can cause various problems. This problem can occur if you mix the epoxy too rigorously. To avoid this problem, mix the epoxy mixture gently.

  1. Off-Gassing

Offgassing is the natural process of the release of air from the epoxy surface. Offgassing is the common problem in an epoxy coating that can cause air bubbles on the surface. You can apply a skim coat of epoxy before pouring the first coat of epoxy on the surface to avoid the problem of off-gassing.

  1. Mixing a large quantity of epoxy

Epoxy takes around 8 minutes to start curing and hardening. However, when you mix a large amount of epoxy in the container, a chemical reaction occurs. Because of this, epoxy starts curing too fast. To avoid this problem, only mix one-quarter of the epoxy you need for the work.

Get it right and avoid mistakes

If you are working with the epoxy the first time, you can save yourself from various mistakes by first testing the epoxy on a small piece of Polywood. After that, you can apply epoxy to your countertop. In this way, you gain more experience. However, never expect everything to be perfect, especially if you are using epoxy for the first time.

Epoxy resin and hardener

Make sure to take resin and hardener in two different containers. After that, take the required ratio of both the chemicals in one container. Make sure to mix them slowly for 5 minutes to avoid air bubbles and other problems. Pour the mixture at the center of the countertop, then spread it around with the help of a foam brush.

Safety tips to consider for applying the epoxy coating

  • You can use epoxy indoors because of its non-toxic nature. But note that the odor is severe. Hence, wear a mask.
  • While working with epoxy, avoid being barefooted because chemicals can fall on your foot. Instead, wear shoes to keep yourself protected in any circumstances.
  • Always use a plastic sheet to protect your floor and furniture from epoxy. Avoid using cardboard or any other material for this purpose.
  • When you start working with epoxy, make sure to wear gloves, safety goggles, and a protective suit.
