Content banner for what Epoxy floor need to cure

Epoxy is a polymer consisting of two components, a resin, and a hardener, mixed and applied to a concrete floor to form a hard, glossy surface. Epoxy flooring has become increasingly popular in recent years due to its durability and resistance to wear and tear. The curing time for epoxy flooring refers to the time it takes to harden and fully reach its maximum strength. In this article, we’ll explore the various factors that influence the curing time of epoxy flooring, the standard curing times for different types of Epoxy, and the importance of proper curing.

Factors Affecting Curing Time

The curing time of epoxy flooring can be affected by several factors, including the type of Epoxy used, the temperature and humidity of the environment, the thickness of the applied layer, and the proper mixing of the epoxy components.

A) Type of Epoxy Used

The type of Epoxy used can significantly affect the curing time of the flooring. 100% solid Epoxy, for example, typically cures more slowly than water-based or hybrid epoxies. Water-based Epoxy has a faster curing time because it contains a smaller amount of resin, which allows it to dry more quickly. Hybrid epoxies contain a combination of solid and water-based components and have a curing time that falls between the two.

B) Temperature and Humidity

The temperature and humidity of the environment can also impact the curing time of epoxy flooring. In general, Epoxy cures more quickly in warmer and drier environments. Conversely, cooler and more humid environments can slow down the curing process. It’s essential to keep the temperature of the environment within the recommended range specified by the manufacturer to ensure that the Epoxy cures appropriately.

C) The thickness of the Applied Layer

The thickness of the applied layer of Epoxy can also affect the curing time. A thicker layer will take longer to cure than a thinner one, as the thicker layer will retain more moisture, slowing down the curing process. It’s essential to apply the Epoxy in the recommended thickness specified by the manufacturer to ensure that it cures properly.

D) Proper Mixing of Epoxy Components

Finally, properly mixing the epoxy components is critical to the curing process. If the two components are not mixed properly, the Epoxy may not cure correctly, leading to a weaker and less durable floor. It’s important to follow the mixing instructions specified by the manufacturer to ensure that the Epoxy cures properly.

Impurities/contamination: Any impurities on the surface or inside the Epoxy or the mixing tools can affect the curing process. Water, humidity, Solvents, oil, or even fingerprints can prevent the Epoxy from properly curing. These impurities can act as inhibitors, preventing the formation of the crosslinked polymer network responsible for the cured Epoxy’s strength and durability. This can lead to a weaker bond, discoloration, or improper epoxy curing.

Standard Curing Times

The standard curing times for different types of epoxy flooring can vary greatly. Below, we’ll discuss the standard curing times for 100% solid epoxy, water-based Epoxy, and hybrid Epoxy.

A) 100% Solid Epoxy

100% solid Epoxy is the most traditional type of epoxy flooring and is known for its durability and resistance to wear and tear. The standard curing time for 100% solid epoxy is typically 24 to 48 hours. However, the Epoxy can take up to 72 hours to reach its full strength.

B) Water-Based Epoxy

Water-based Epoxy has a faster curing time than 100% solid epoxy, as it contains a smaller amount of resin, which allows it to dry more quickly. The standard curing time for water-based Epoxy is typically 12 to 24 hours. However, it’s important to remember that water-based Epoxy is not as durable or resistant to wear and tear as 100% solid epoxy, so it may need to be reapplied more frequently.

C) Hybrid Epoxy

Epoxy hybrid adhesive formulations have enabled unmodified epoxy systems to offer enhanced capabilities such as improved flexibility/elongation, impact/thermal cycling resistance, peel strength, long term durability. The standard curing time for hybrid Epoxy is typically 12 to 24 hours; these desirable properties have been achieved by blending the epoxy resin with other polymeric resins. Liquid/paste hybrid adhesive epoxy-urethane and epoxy-polysulfide compositions are employed for structural bonding of similar/dissimilar substrates and exhibit characteristics only obtainable through a combination of resin families. These products overcome the shortcomings of conventional epoxy system modification that incorporate flexibilizers/tougheners, fillers/extenders, and promoters to extend their usability in industrial assembly applications.

Easy-to-apply/cure epoxy hybrid adhesive materials are designed to increase productivity and cut costs. They are engineered to withstand long-term exposure to gasoline, natural gas, alcohol, and crude oils. They can be dispensed on complex metal, plastic, rubber, and ceramic parts, including lighter, thinner surfaces, and polymerize at room/elevated temperatures.

Importance of Proper Curing

Curing plays an essential role in the strength development and durability of Epoxy. Curing takes place immediately after Epoxy flooring application and finishing; it involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods.

Temperature plays an essential role in the curing process, as epoxy resin is a thermosetting polymer. The right conditions for Epoxy to cure usually vary depending on the specific product, but in general, epoxy resins cure best at temperatures between 72-74°F (22-24°C) and relative humidity levels between 40-60%. Low temperatures can slow down the curing process and, in extreme cases, can cause the Epoxy to not cure. High temperatures can speed up the curing process but cause the Epoxy to cure unevenly, resulting in a weaker bond.

A) Hardness and durability of the floor

Epoxy floor coatings provide long-lasting and durable protection for flooring. Many commercial and industrial spaces use epoxy flooring in Nigeria because it is incredibly versatile and has one of the highest quality floor coatings available. The hardness of Epoxy is superior, and a wide variety of colors are available. Epoxy has a fairly low maintenance while providing benefits with a long lifespan. The epoxy coating is made from a combination of Resin and Hardener. When these components are applied with one on top of the other, the result causes a chemical reaction. This ensures a coating that is tightly bonded, extremely hard, and stronger than either of the components when used separately.

B) Aesthetics and Longevity

One of the most common uses for an epoxy coating is to beautify and protect concrete flooring. It additionally works very well on metal, vinyl, and tile. Epoxy floor coatings are known for their durability. They resist damage due to impacts and abrasions and stand up very well under heavy foot traffic. Even under heavy and consistent wear, an epoxy floor coating will perform well and look good. This coating additionally protects the floor underneath. The longevity of an epoxy floor coating is dependent on a lot of different factors. The average time before the coating requires replacement is five to ten years. An epoxy floor coating improves the aesthetics of the flooring. The coating is available in different textures, including a confetti-like color flake, metallic shimmer, and nearly any color imaginable.

C) Resistance to chemicals and impacts

The chemical-resistant epoxy composition is highly resistant to chemical attack. It can be advantageously used for short or long-term direct, total, continuous, or intermittent immersion applications, such as interior and exterior protective coatings, adhesives, encapsulants, or resin-fiber composites.

Methods for Accelerating the Curing Process

Epoxy resin is a versatile and durable material that is commonly used in a variety of applications, including in the creation of jewelry, home decor, and even in industrial settings. However, one common issue many users face is that the resin can take a long time to dry, which can be frustrating and time-consuming. In this blog, we will explore tips and techniques to speed up the epoxy resin curing time.

A) Using a dehumidifier

 A dehumidifier is an appliance that removes moisture from the air at home or in your workspace, which can greatly help. But this will also need to be kept on during the curing phase.

Well, humidity is moisture in the air; if moisture gets near or into Epoxy resin, it will affect the liquids and potentially cause issues during the curing process. As we previously said above, you’re not always going to know if the humidity level is too high to work with epoxy resin. So the only way to know if it is is to monitor it on a device specifically designed for this purpose. First, you can purchase a humidity gauge if you haven’t already got one.

One thing to watch if you are using a dehumidifier is that you use this in an enclosed room; if you have any windows open, then you will just get more moisture in the air. Because you will then be using our resin in a non-ventilated space, you will need to use a respirator to protect your health as a safety precaution.

B) Increasing the temperature

 The ideal temperature for curing ArtResin to 75-85ºF / 24-30ºC. Cure time is affected by temperature: warmer temperatures facilitate curing, and colder temperatures slow curing. Place a space heater or heat lamp near your piece to encourage the resin to cure faster.

C) Using a fan to circulate air

Epoxy should be air-dried. Although Epoxy is a fast-drying paint, it can take 48 to 72 hours to dry completely, depending on environmental conditions. Open as many windows and doors before painting as you can. Not only will this help with the fumes from Epoxy paint, but it will also help expedite the drying process once the floor is painted. Once the floor is painted, keep windows and doors open as much as possible during the first 48 hours.


Epoxy Flooring components are a versatile and durable material commonly used in various applications. Still, many users face a challenge: the long drying time. In this blog, we have discussed several ways to make epoxy resin dry faster. These include using a humidifier, increasing ventilation, and increasing the temperature. Temperature and humidity play a key role in the curing process. The epoxy resin cures best at temperatures between 72-74°F (22-24°C) and at relative humidity levels between 40-60%. High humidity levels or low temperatures can slow down the curing process or lead to a weaker bond. Mixing ratio and mixing time are also important factors. The correct mixing ratio of the two components is critical for proper curing. Mixing the Epoxy for a sufficient amount of time ensures proper mixing and activates the curing process.

Recap of key points

Using these tips and techniques, you can help speed up the drying process of epoxy resin and get your projects completed more quickly. Remember that, even with these tips, epoxy resin can still take a long time to dry completely, and proper ventilation and safety measures should be used.

Final thoughts and recommendations

Remember that the curing time will vary depending on the brand and type of Epoxy you use. Always consult Polymers Technologies’ recommendations for use and safety precautions before using a fast-setting epoxy. Additionally, it’s important to monitor the temperature of the Epoxy throughout the curing process with a thermometer and to keep the temperature consistent, as uneven heating can lead to improper curing and weaken the final product.
