Posted by Armor Garage LLC on May 1st 2025
This is similar to the question of how long does epaoy paint last. The answer is, it depends. we'll go through what determines dry times and expalin the difference between dry times, pot life and cure times.
When it comes to strong and visually appealing flooring solutions, epoxy paint stands out for its durability, long life, and glossy finish. Whether you're upgrading your garage or refreshing a workspace, knowing how long epoxy paint takes to dry is essential to achieving the most out of your floor coating. With the right product and preparation, epoxy application can be a very rewarding DIY project. In this guide, we’ll break down the drying process, key factors affecting cure time, and how DIY users can get great results using ArmorGarage epoxy kits.
What Is Epoxy Paint?
Epoxy paint, sometimes referred to as an epoxy coating, is a two-part system made of epoxy resin and a hardener. Once mixed, this combination chemically transforms to a tough, seamless surface that bonds directly to concrete. Known for its resistance to wear, chemicals, and heavy impacts, epoxy is ideal for garages, workshops, and commercial areas.
Unlike traditional paints that sit on the surface, epoxy chemically bonds with the concrete, forming a thick, durable layer. A high performance epoxy primer or epoxy coating will form an unbreakable bond to the top layer of your concrete slab. All ArmorGarage epoxies and primers are pull tested to make sure the concrete fails before the coating does.
The Process of Applying Epoxy Paint
Applying epoxy paint successfully involves a few key steps that are easy to follow using a DIY epoxy kit. Here's an overview of the process:
Surface Preparation
Proper surface prep is the most important part of any epoxy application. The floor should be clean, dry, and free of grease, debris, or existing coatings. Cracks and holes should be filled, and depending on the condition of the surface, light etching or grinding may be needed to improve adhesion.
Primer Application (If Required)
Some ArmorGarage epoxy kits include or recommend a primer to further strengthen the bond. If included, it should be applied to the prepared surface and given time to dry before applying the epoxy. The primer will take about 5-6 hours to dry at 75 degrees. It will take longer in cooler temperatures and shorter in higher temperatures. Apply the epoxy layer no more than 20 hours after primer application. After 20 hours the proes in the epoxy primer close up and then it's like coating over glass.
Mixing and Applying the Epoxy
The resin and hardener components are mixed thoroughly and then rolled or brushed onto the surface in an even coat. Our epoxy kits come with specialized squeegees to spread the coating at the proper thickness. Following the instructions provided in the kit ensures each layer dries properly and bonds effectively. We strongly recommend reading the "How To Prep & Paint Your Floor" article in the "Need To Know" section, in fact there a few articles located there that you should read before purchasing or applying any epoxy floor coating. Typical high quality epoxies have a pot life (working time) of about 30-35 minutes and will take abour 10-12 hours to dry depending on temperature and humidity. Most epoxies must be applied to floors 55 degrees and warmer.
Topcoat or Clear Coat
For added protection and a glossy finish, ArmorGarage kits may include a clear topcoat. This layer enhances durability and appearance, especially important in areas with heavy foot or vehicle traffic. again apply the topcoat within 20 hours of applying the epoxy layer. This ensures both will bond to each other. When applied within the time windows the primer, epoxy and topcoat will fuse together to form a monolithic block of super tough epoxy.
Our topcoats usually dry within 6-8 hours, when you can walk on it and put your stuff back on the floor, keep heavy traffic off for as long as you can. The longer the better.
How Long Does Epoxy Paint Take to Dry?
Typically, epoxy paint dries to the touch within 12-14 hours, but full curing can take 1-4 days. It's important to distinguish between drying and curing:
- Drying Time: When the surface feels dry and can handle light foot traffic.
- Curing Time: Once the epoxy dries on the surface it's still chenically drying on the inside. This is called the curing process. Once fully cured is when the floor can handle vehicles or heavy loads.
Always follow the drying and curing guidelines included with your ArmorGarage epoxy kit, as some systems may cure faster or slower depending on the formula. We always recommed allowing the epoxy layer to dry overnight before applying the topcoat.
How do you know when any epoxy layer is dry, press your thumb into the coating, no thumb print means it's dry, a thumb print means it still needs time. Never apply the next coat until the previous coat is fully dry to the touch.
Factors That Influence Epoxy Drying Times
Ambient Temperature
High humidity (over 90%) can interfere with the curing process, resulting in a tacky finish. It’s best to apply epoxy in 55-100 degrees with no rain in the forecast. A light drizzle is ok, if doing a garae make sure you keep the door closed. The general rule is the cooler the floor the longer the dry times are with the opposite being the case.
Type of Epoxy Product
Not all epoxy products are the same. ArmorGarage offers a wide range of solutions designed for different needs, from quick installations to heavy-duty applications. Always choose the formula that best fits your project. Ask one of our experts if you're unsure which system is best for you.
Thickness of Application
Applying epoxy at the recommended coverage rate allows it to dry and cure more evenly. Thicker than recommended layers may trap air or moisture and take longer to cure. At ArmorGarage we alwasy supply you with sufficient quantities of epoxy. An easy way to determine proper thickness application is to divide your square footage by the number of gallons this results in the square footage per gallon application rate.
Surface Preparation
The bond strength of epoxy depends heavily on surface prep. A clean, prepped surface ensures proper adhesion and prevents issues like peeling or bubbling later on.
Tools and Environment
Using the right tools, like rollers, mixing paddles, squeegees and spike soles, can make a big difference. While heat lamps can speed up curing in cold environments, they should be used cautiously to avoid overheating.
Why Following Drying Instructions Matters
Rushing the curing process or using the floor too early can result in premature wear, bubbling, or reduced durability. ArmorGarage kits include detailed curing timelines that ensure your floor reaches maximum strength before heavy use.
For example, garage floors that aren't fully cured may peel or lift under hot tires. Giving your epoxy the proper time to set helps ensure long-term performance and a finish that lasts for years.
