In this article, I’ll tell you about epoxy mistakes. I’ve been a bit familiar with epoxy resin for a while now. I want to share the five biggest problems I’ve encountered. I’ll also share the solutions I’ve found so far. Maybe it will help those of you who have questions like, “Why did my resin bubble? Why didn’t it set?”
Many of us watch epoxy resin videos on YouTube, try them out, and unfortunately, they can’t get those “shiny and smooth” products. This usually results in disappointment. I’ll share my five problems and the solutions I’ve come up with.
1 – Epoxy Resin is a Messy Business
Working with epoxy is a messy business. It’s incredibly messy. It contaminates your hands, face, clothes, and everything else. The fumes are also harmful to your health. Don’t let the harmlessness of cured epoxy fool you into thinking that breathing the fumes during the process is harmful. Remember this. Be very careful when working with epoxy. Don’t take it too seriously. For both your comfort and your health. That’s why you absolutely must have certain equipment.
First, you need a very good silicone mat. This will protect your desk and surroundings from contamination, give you peace of mind, and make working much more comfortable. Before buying a silicone mat, I had to be more careful. I was wasting a lot of time trying to wipe up drips.
Second, have gloves and a mask. This will protect you from contamination and allow you to work more carefully, as you’ll be able to spend more time in an unsafe environment. Working without gloves can make your hands sticky, which is very uncomfortable. It’s also very difficult to clean. Without a mask, you’ll be breathing in epoxy fumes, which are both unpleasant and unhealthy. This limits your work time.
The last and most important point about cleaning is alcohol. Be sure to have plenty of isopropyl alcohol on hand. This is perhaps your only aid in cleaning your hands and the surrounding area. I’ve tried many products, but I haven’t found anything as effective as alcohol.
2 – Be careful with silicone molds
Poor silicone molds not only compromise the quality of the product but also deteriorate quickly. You’ll end up paying more for a cheaper price. Use quality silicone molds. Also, apply a release agent to the mold. Epoxy products have difficulty releasing from the molds as the air around you cools or the humidity decreases. Incorrect mixing ratios can also contribute to this. In this case, the product sticks to the mold, damaging both the product and the mold. This is a problem I encounter frequently. The solution is a bit complex. You need to pay attention to the hardener and epoxy ratios, color ratios, humidity, and temperature. There are many factors involved. A good release agent is your biggest help.
3 – The Trouble with Bubbles
Your biggest problem when working with epoxy resin is bubbles. If you don’t have a vacuum canister, it’s even more difficult. Even if you do, you can’t put everything in one canister. However, you can reduce bubbles by placing the containers you mixed in. However, bubbles can reoccur during pouring. This problem is very difficult to completely eliminate. A vacuum pump can really help. But it’s not a cheap solution. Otherwise, mix the epoxy slowly. Pour slowly as well. Let the mixture sit for 5-10 minutes before pouring. Then, quickly flick a lighter over it to remove any bubbles. Bubbles are a formidable enemy. They’ll pop up somewhere. You might not even see them.
4 – Epoxy never releases from the mold like you see on YouTube
Don’t get excited by seeing those beautiful epoxy products on YouTube videos. It can be disappointing. Epoxy castings will always have imperfections, especially with larger pieces. If you knew what we encounter in the chess pieces we cast? If we make ten, we have to discard nine of them, right from the start. Unevenness, jagged surfaces, uneven heights on the edges, faded areas… Post-processing is absolutely necessary. You’ll have to work especially hard with sandpaper. If you’re working with epoxy, you’ll have to work your butt off. Because you’ll be sanding for hours. You may need to polish afterwards, but the most reliable solution is to sand and then apply a thinner coat of epoxy. That’s how we do it. First, we sand and smooth the product, then apply another thinner coat.
5 – Epoxy work requires patience
If someone tells you to wait a day for an epoxy job, wait two. Don’t say, “Well, they say it takes one, they’re reliable, I’ll just wait half a day.” It might be enough. The person is doing the job in December, and you’re in July. Epoxy can dry in half that time. However, it can also be the other way around. It’s highly dependent on temperature and humidity. Or the product you’re holding might appear dry. It comes out of the mold perfectly, but a 1cm section in the upper right corner still hasn’t cured. You go and touch it, and your one-day wait is ruined. Remember, epoxy is very difficult to repair once it starts to dry. Instead of wasting hours, be a little more patient. Epoxy requires patience. Otherwise, you should find another hobby. Because impatience will eventually cost you.
