Epoxy resin cannot be cured well, soft/bendy/sticky?
Epoxy resin fails to achieve a glossy surface?
In this blog post, we will guide you through the process step-by-step, helping you create beautifully cured epoxy resin projects.
Step 1: Measure Accurately
Start by measuring equal parts of epoxy resin and hardener. Use a scale or measuring tools to ensure the right ratio. Accuracy is crucial for proper curing, so take your time to measure precisely.
If you are not sure how much you should measure for your work, please refer to the Resin Calculator.
Step 2: Prepare
- Before starting, clean and prepare your workspace.
- Ensure good ventilation to minimize exposure to fumes. A well-ventilated area will help dissipate any odors emitted during the curing process.
- Ensure the mould is clean and dry so as not to interfere with curing.
Step 3: Thoroughly Mix the Resin and Hardener
- Combine the measured resin and hardener in a mixing container. Stir slowly and consistently for approximately 2-3 minutes.
- Scrape the sides and bottom of the container to ensure complete and thorough mixing.
- You can color and add any decorations you want after this step.
Note: If adding liquid pigments, be careful not to add more than a maximum of 6% of the resin mixture as this may affect the curing effect.
Step 4: Check for Air Bubbles
- Allow the mixture to rest for a few minutes after stirring. During this time, any air bubbles will rise to the surface.
- To eliminate them, use a heat gun or torch to gently pass the flame over the resin surface.
- Alternatively, you can consider using a vacuum chamber to remove bubbles before pouring.
Step 5: Pour and Level
- Pour the mixed epoxy resin onto your desired surface or into a mold. Ensure even distribution of the resin to achieve a level and smooth finish.
- A spreader or foam brush can help with this process.
- Take your time to ensure the resin is evenly spread across the project. If you are having problem getting a level operating surface, you may consider purchasing a Teexpert leveling board.
Step 6: Remove Additional Bubbles
- After pouring, observe the surface for any additional air bubbles that may rise. Use a heat gun or torch again, carefully passing the flame over the resin to eliminate these bubbles. Exercise caution not to overheat or scorch the resin while doing so.
- Or spray the surface with 99% alcohol. Be careful not to use too much as it may affect the curing.
Step 7: Allow Proper Curing Time
- Refer to the instructions for the recommended curing time and temperature.
- Generally, epoxy resins require 12-72 hours to fully cure, depending on the specific type.
- Ensure the curing temperature remains within the recommended range for optimal results.
Step 8: Protect from Dust and Debris
- While the epoxy resin cures, protect the surface from dust, debris, and any disturbances that may affect the finish.
- Consider covering the project with a dust-free enclosure or utilizing a dedicated workspace to prevent unwanted particles from settling on the resin.
Step 9: Optional Post-Curing
Some epoxy resins benefit from a post-curing process. This involves applying controlled heat or leaving the cured project in a warm environment for an extended period. Review the manufacturer's guidelines for specific post-curing recommendations, as this step may enhance the resin's final properties.
By following these step-by-step instructions and guidelines, you can achieve the best curing effect with any epoxy resin systems.
Remember to prioritize safety by wearing appropriate protective equipment and working in a well-ventilated area.
