How to Properly Mix and Apply Epoxy Resin

Epoxy resin in the Philippines is a popular material used for a variety of applications, including woodworking, jewelry making, and even automotive repairs. It is a two-part system that consists of a resin and hardener, which when mixed, create a strong and durable bond. However, proper mixing and application of epoxy resin are critical to ensure a successful outcome. In this blog, we will discuss how to properly mix and apply epoxy resin.


Step 1: Preparation

Before you begin mixing the epoxy resin, it is important to prepare the surface you will be working on. Ensure the surface is clean and dry, free from dust, dirt, and any other debris. Cover the surface with plastic or a drop cloth to protect it from any spills or drips. You should also wear gloves and safety goggles to protect yourself from any potential hazards.


Step 2: Measure

Measuring the correct amounts of epoxy resin and hardener is crucial for the success of your project. The resin and hardener come in separate containers, and it is important to follow the manufacturer’s instructions to determine the correct ratio of resin to hardener. The ratio typically ranges from 2:1 to 1:1, depending on the specific product.

Using a measuring cup or a digital scale is recommended to ensure accuracy. A measuring cup with markings for both the resin and hardener can be used to measure the correct amounts of each component. It is important to note that you should not use the same measuring cup for both the resin and hardener, as this can cause cross-contamination and affect the chemical reaction.

If using a digital scale, place a clean mixing container on the scale and tare it to zero. Then, pour the required amount of resin into the container, and measure the exact amount of hardener required. Make sure to measure both the resin and hardener by weight, as this is the most accurate way to measure.


Step 3: Mix

Once you have measured the correct amounts of resin and hardener, it’s time to mix them. Pour the resin into a clean mixing container, and then add the hardener. Use a stir stick to mix the two components thoroughly for at least 2-3 minutes, making sure to scrape the sides and bottom of the container to ensure a complete mixture. Be sure to mix only the amount of epoxy resin you will need, as once the two components are mixed, the epoxy will start to harden.


Step 4: Wait

After you apply epoxy resin, it is important to let it sit for a few minutes to allow any bubbles to rise to the surface and pop. This will prevent any air pockets from forming in the epoxy.


Step 5: Apply

Once the epoxy resin is mixed and bubbles have dissipated, it is ready to be applied. Use a brush or a pour spout to apply the epoxy resin to the surface. Be sure to spread it evenly, making sure to cover the entire surface. If you are working with a deep pour, pour the epoxy resin into layers, allowing each layer to cure before pouring the next.


Step 6: Cure

Once the epoxy resin has been applied, it is important to allow it to cure completely before using or sanding the surface. Curing is the process by which the epoxy resin hardens and forms a strong bond. The curing time for epoxy resin can vary depending on several factors, including the specific product, the thickness of the layer applied, and the environmental conditions.

Most epoxy resin products have a recommended curing time provided by the manufacturer. It is important to follow these instructions carefully, as deviating from the recommended curing time can result in an incomplete cure and weaken the bond. In general, the epoxy resin cures faster at higher temperatures and slower at lower temperatures.



It is important to note that epoxy resin will go through several stages during the curing process. The first stage is the liquid stage, during which the mixture is still pourable and workable. The second stage is the gel stage, during which the mixture begins to thicken and becomes less workable. The final stage is the fully cured stage, during which the epoxy resin has hardened and formed a strong bond.

During the curing process, it is important to protect the surface from dust, debris, and any other potential contaminants. Cover the surface with a plastic sheet or a dust cover to prevent anything from sticking to the surface. It is also important to avoid any movement or disruption of the surface during the curing process, as this can cause the epoxy resin to become uneven and compromise the final outcome.


Key Takeaway

Mixing and applying epoxy resin can seem daunting at first, but with the proper preparation and careful measurement, it can be a rewarding experience. Follow these steps to ensure a successful outcome, and you will be able to create beautiful and durable projects with epoxy resin.
