Epoxy Countertops Gone Wrong | 13 Common Problems & How To Fix
Epoxy countertops are quite popular these days and for a good reason. They are strong, durable, and heat-resistant, making them an ideal surface for your kitchen. Plus, they come in various colors and styles so that you can customize your space.
Sometimes you get your epoxy countertops gone wrong, most of which can be fixed with little know-how. Below are common epoxy countertops issues and tips on how to fix them gathered from my own experiences.
1 – Wrong Mixing Ratio
The most common problem with epoxy countertops is using the wrong mixing ratio. Epoxy is a two-part resin that must be mixed in the correct ratio to set properly.
If too much or too little of one part is used, the epoxy will not set correctly and will be weak and prone to chipping and cracking.
Therefore, follow the mixing instructions carefully and use a digital scale to measure the correct amount of each part.
2 – Incorrect Curing Time
Another common problem with epoxy countertops is that they are not cured for the correct amount of time.
Epoxy needs time to set and harden properly. Do not try to hurry the process by using a hairdryer or placing the object in direct sunlight.
The heat will cause the epoxy to set too quickly, resulting in a weak and tacky surface. Allow the epoxy to set for the time specified in the instructions before removing it from the mold or touching it.
Epoxy must be cured for at least 24 hours – preferably 48 hours to set properly.
3 – Bubbles In The Epoxy
Have you ever noticed small bubbles in your epoxy countertop? These are actually caused by outgassing – when gasses escape from the pores in the concrete and get trapped under the epoxy due to incorrect mixing. Temperature changes can also cause bubbles to form.
The best way to fix this problem is to apply a second layer of epoxy. You will need to sand the area smoothly and reapply the epoxy.
4 – Cracks In The Epoxy
One of the reasons why people love epoxy countertops is because they are incredibly strong and durable. However, if the epoxy is not mixed correctly or cured for the correct amount of time, it can be susceptible to cracking.
To fix this problem, you’ll need to fill in the cracks with an epoxy filler and then sand down the area smoothly before reapplying the epoxy topcoat.
5 – Waves And Ripples In The Epoxy
Ideally, your epoxy countertop should be smooth and flat. However, if the epoxy is not mixed correctly or applied evenly, you may end up with waves and ripples on the surface. The finished result of your countertop will not be as smooth as you would like.
If you notice the waves and ripples, you will need to sand down the area until it is smooth and then reapply the epoxy.
6 – Not Considering The Temperature
When working with epoxy, it is crucial to consider the temperature. The ideal working temperature for epoxy is between 65-80 degrees Fahrenheit.
If it is too cold, the epoxy will not set properly and may become cloudy. If it is too hot, the epoxy will set too quickly and be difficult to work with.
7 – Poor Surface Preparation
You cannot just pour epoxy onto your countertop and expect it to turn out perfectly. The surface must be properly prepared before the epoxy is applied. This means it should be clean, dry, and free of any grease, oil, or dirt.
If the surface is not prepared correctly, the epoxy will not adhere properly and will not be set correctly. Additionally, you may notice a cloudy finish or small bubbles in the epoxy.
8 – Applying Too Much Or Too Little Epoxy
When applying epoxy, you need to use the correct amount. If you apply too much, the epoxy will be difficult to work with and take longer to set. Also, it will take longer to set and may end up being uneven. The ideal thickness for epoxy will depend on the application area.
On the other hand, if you apply too little, the epoxy will not properly adhere to the surface and may not set correctly. Always follow the mixing instructions carefully and use a digital scale to measure the correct amount of each part.
9 – Using The Wrong Product
There are many types of epoxies on the market, and it is vital to choose the right one for your project.
Choosing the wrong product will result in poor results and may damage your countertop. If you are unsure which product to use, always consult with a professional.
10 – Not Using A Respirator
Another important safety consideration when working with epoxy is to make sure that you are wearing a respirator.
Epoxy fumes can be harmful if inhaled, so you need to protect yourself by wearing a respirator whenever you are working with epoxy.
11 – Yellowing
If your epoxy countertop starts to turn yellow, it is probably because of the UV rays.
The best way to prevent this is to apply a UV-resistant topcoat.
12 – Staining
If you spill something on your epoxy countertop, you may notice a stain.
To remove the stain, sand down the area and reapply the epoxy. You may also want to consider sealing your countertop with a clear sealer to help prevent future staining.
13 – Chipping
This is usually caused by using too much pressure when cleaning or by cutting directly on the countertop’s surface.
To make it new again, sand down the chipped area and reapply the epoxy topcoat. Sealing your countertop with a clear sealer can also help prevent future chipping.
Conclusion
While beautiful and durable, epoxies aren’t perfect. Some things can go wrong during the installation or even during normal use.
By following the tips above, you can avoid any major issues with your own epoxied surfaces. This way, the final product can be satisfactory.
