Epoxy application is a great way to give ordinary surfaces a durable and smooth finish, along with a professional look. Unfortunately, most projects fail not because the material is wrong but due to simple mistakes during the application. If you expect your results to be effective, strong, and long-lasting, you need to identify and avoid the mistakes first.
This article will serve as your guide to applying epoxy properly and getting a neat, high-quality finish.
The Most Common Problem that Causes Poor Surface Preparation
Improper surface preparation is one of the most significant challenges when working with epoxy (the adhesive) to create an epoxied surface.
Incorrect Mixing Ratios of Epoxy
Incorrect mixing ratios of epoxy are definitely one of the most common mistakes when using epoxy. In fact, epoxy generally consists of two materials – resin and hardener. When these two are mixed in the wrong proportion, it can spoil the whole batch.
For instance, if the component ratio is inaccurate, the epoxy may not harden properly. The epoxy may stay tacky, soft, or develop an uneven texture.
So, the best practices can be as follows:
- Don’t take any chances with the mixing
- Follow the manufacturer’s dosage instructions to the letter.
- Measure components accurately with proper tools.
- Mix at a slow speed, but ensure that the mixing is thorough to avoid air bubble entrapment.
After all, accuracy is what matters when using epoxy.
Applying Epoxy at the Wrong Temperature
As with many other things, temperature is a major factor in how epoxy works. Putting it on when the conditions are bad can cause problems. First of all, if it’s too cold, the epoxy curing process may slow down or even stop. And, on the other hand, if it’s too warm, the epoxy can harden so quickly that it becomes almost impossible to work with.
Typically, you want to:
- Use a controlled indoor environment (normally around 2030C)
- Stay away from a high level of humidity
- Don’t make a coating during sudden or extreme weather changes
Take a look at the manufacturer’s recommended temperature range before you start
Rushing the Application Process
Many people apply epoxy too quickly, especially when they are covering an expanse of floor. As a result, there are many areas where the epoxy appears to have been applied incorrectly (e.g., non-uniform application, visible imperfections).
Epoxy needs time to disperse, level, and fully cure. If you rush through your application too quickly, any bubbles that form will eventually become a part of the finish, or streaks will occur.
What to do:
- Use small sections
- Allow enough time between coats to fully cure
- Use the proper tools (rollers/squeegees)
Ignoring Bubbles and Imperfections in Epoxy
Bubbles form when epoxy is applied either too quickly during mixing, or the surface is porous.
If you don’t remove the bubbles before the epoxy cures, they will become part of the final finish and destroy the completed product.
How to fix bubbles:
- Use a heat gun or torch to remove them
- Apply slowly to reduce bubble formation
- Seal porous surfaces before applying an epoxy coat
Wrapping Up
Using epoxy is not difficult, but it takes a lot of care to do so correctly. The major causes of failure are easily avoided with the proper information. To achieve a quality finish, you will need to complete every task correctly. If you want to start your next epoxy project with confidence or achieve the best results, consider consulting professionals or using quality products designed for today and tomorrow.
