If you’ve ever wondered how to fix bubbles in epoxy flooring, you’re not alone. There are many causes of this problem, including improper application, outgassing, and excessive air flow. This article will cover some of them and provide some tips on how to eliminate them. Ultimately, a great epoxy floor should last for many years. It’s just a matter of following the steps outlined in this article.

Osmotic blistering

One of the most common problems associated with epoxy flooring is osmotic blistering. Osmotic blisters are bubble-like cracks found on a coated surface due to a combination of factors. These conditions include constant exposure to high humidity or water, which can be a result of problems with the substrate, moisture vapor from the ground or the curing process itself. Also, temperature differences can cause blistering damage.

The process of osmotic blistering in epoxy flooring begins when moisture penetrates the coating’s surface and accumulates under the layer of paint or epoxy. The moisture subsequently builds up and creates the pressure that results in the blistering. The process occurs due to osmosis, while non-osmotic bubbling is caused by a different mechanism. A well-maintained coating should be able to resist osmotic blistering and maintain its durability for as long as possible.

Outgassing

The presence of outgassing is a normal, temporary phenomenon associated with the installation of an epoxy floor coating. While this is an unattractive side effect, it has minimal impact on the coating’s overall cohesion. If you notice outgassing, the first step is to recoat the floor with the same type of coating. However, you should be aware of the potential downsides of this process.

Outgassing occurs when the coating deteriorates due to variations in room temperature. The voids in the coating cause the epoxy to react with residual oil or silicone. This causes bubbles on the surface of the flooring. If left unchecked, outgassing can cause the floor to crack and disintegrate. As a result, it is important to take appropriate measures to avoid outgassing in epoxy floors.

Proper application

Often, the main reason for bubbles is improper surface preparation. Excessive airflow, due to open doors and HVAC systems, can cause bubbles on the floors. Similarly, excessive heat from heaters and extreme weather can cause bubbles in the floor coating. So, proper surface preparation is vital for a bubble-free floor. Here are some tips to help you avoid bubbles during the application process:

A high humidity level can cause the epoxy coating to fail to set. While this can compromise the aesthetics of the flooring, it will not affect the durability of the coating. A skilled epoxy contractor will know the most effective methods to prevent fisheyes, including proper surface preparation. Proper surface preparation is the most important step to a bubble-free floor.

Remove air bubbles

If you have recently installed epoxy flooring on your floor, you have probably experienced the problem of air bubbles. This is caused by air trapped in the concrete slab. This can cause dirt and liquids to leak through the flooring. You should take the necessary steps to cure the concrete slab before applying the coating. During this process, you must remember to avoid using any low-quality coating, since they may contain solvents or chemicals that are not necessary for epoxy flooring.

To fix the problem, you can try several methods. You can either use a heat gun or a blow dryer. Use caution when using either of these tools, because the heat could damage the epoxy flooring permanently. If you choose the latter method, make sure to follow the manufacturer’s instructions, and make sure that the product is applied correctly. This may not be possible if the bubbles are too large.
