Does Water Affect Epoxy Flooring? 

When epoxy floor is still wet, water can affect it in a negative way. However, when the epoxy floor is completely cured, it becomes waterproof. That’s why epoxy floor coating is considered a great and popular choice for moisture-prone environments such as garages, basements, and bathrooms. 

So, if you are still wondering, ‘Is epoxy resin waterproof?’ The answer is yes, when it is fully cured. Epoxy floor coating creates a barrier that prevents water from penetrating the substrate. Technically, nothing can penetrate cured epoxy resin floors, not even water.

How Can Water Exposure Affect Epoxy Resin? 

Is epoxy resin waterproof? Both yes and no! It depends. Epoxy floor coating is waterproof; however, water can negatively affect epoxy flooring during the curing process. When you are applying epoxy resin to the floor, try to keep water and moisture away from the place. This way, you can make sure that your epoxy floor will last for years to come. Water exposure during applying epoxy floors can lead to problems such as: 

• Blistering or bubbling on the surface 
• Cloudy finishes or an incomplete, uneven surface 
• Weak adhesion! This problem can lead to peeling or lifting of epoxy coating over time. 

If you want to enjoy your epoxy coating, it’s necessary to avoid any water exposure or humidity during the curing period. Curing of epoxy coating can take anywhere from 24 to 72 hours, depending on the type of epoxy. If you live in high-humidity environments, the curing time may take even longer. Therefore, do not forget to carefully follow the manufacturer’s instructions and guidelines. 

Factors with Negative Impact During Epoxy Curing Time 

If you want your epoxy flooring to last for years to come, you have to apply it carefully. Epoxy resin coating is extremely sensitive during applying, and the curing process is one of the most sensitive times for epoxy resin. 

In order for epoxy coating to last long, you have to consider several important factors and their impact on the final result. If not properly managed, these factors can negatively impact the final result. 

Moisture

When epoxy resin is curing, your biggest enemy is moisture. If you don’t want to face any defects such as bubbling, improper bonding, or a cloudy finish, it’s necessary to prevent any exposure to water before the epoxy has fully hardened. It doesn’t matter if you want to use epoxy flooring for a humid place like bathrooms or basements, you just need to make sure that the application environment is dry and free from water exposure during curing. 

Temperature Fluctuations

Both high and low temperatures have negative impacts on the epoxy curing process. Problems like incomplete bonding occur due to cold temperatures during epoxy application and curing. On the other hand, high temperatures will cause the epoxy to cure quickly, resulting in cracks or shrinkage. 

Factors Affecting Epoxy Floor Performance and Longevity

Is epoxy resin waterproof? Yes, cured epoxy is totally waterproof and durable. However, several key factors affect the longevity and performance of epoxy floors. 

1-Surface Preparation 

The first and most important part of the epoxy application is surface preparation. Before applying epoxy resin, you should thoroughly clean the surface. The surface must be clean, dry, and free from dust, oil, or grease. If you don’t clean the surface properly, it can result in poor adhesion, which can reduce the epoxy’s durability and water resistance. 

2-Application Technique 

Of course you can apply epoxy by yourself. You can even find DIY-Friendly epoxy kits on the market and thousands of tutorial videos on YouTube. However, you should know that incorrect application techniques, such as uneven spreading or improper mixing ratios of resin and hardener, can cause some serious problems. 

If you are really good at DIY projects, then follow the manufacturer’s instructions on the kit to achieve a fully cured and waterproof result. Otherwise, our professionals are here to help you along the way. 

3-Environmental Conditions 

When the epoxy is completely cured, it can resist anything! However, you need to be very careful during application and curing time. Temperature fluctuation and high humidity levels during applying epoxy resin can impact the epoxy’s performance. Generally, the ideal temperature range for applying epoxy is typically between 60°F and 80°F.
