1.Workspace & Material Preparation
- Epoxy Resin: Regular Epoxy Resin 1:1
- Tools: Measuring Cup, Mixing Stick or Electric Mixing Cup, 75% Alcohol (for cleaning)
- Protective Equipment: Always wear nitrile waterproof gloves, a waterproof apron, and a respirator for safe handling.
2. Environment Setup
- Ideal Conditions: Maintain a temperature between 73–78°F with humidity no higher than 50–60% RH.
- Ventilation: Work in a well-ventilated area, ideally near a window or use an air purifier for better airflow.

Step 1: How to Measure Resin
1. Molds with volume markings: Mix resin according to the marked volume.
2. Molds without volume markings:
Pour water into the mold → Pour the water out into a measuring cup and read the volume → Mix resin 1：1 by volume according to the measurement.
Tip: Add 10% extra when mixing to compensate for any loss during pouring.
Step 2: Mixing Ratio
- Single batches resin mixing ≤ 8oz: Avoid mixing too much at once to prevent overheating and wasted resin. If you need more than 8 oz, divide it into separate batches to control the reaction speed.
- Strict 1:1 volume ratio: Mix the resin 1:1 by volume. Incorrect ratios may cause the resin to stay sticky or not cure properly.
Tip: When mixing, you'll notice thin, silk-like line in the resin. This happens due to the different densities of Part A and Part B. This line can help identify if you've accidentally poured from the same bottle twice.
Step 3: Mixing Method
- Mixing direction: Mix the resin in one direction, maintaining a constant speed while scraping along the sides and bottom of the cup to fully combine the resin and hardener.
- Observe the state of resin : At first, you'll notice a silky texture. Once the swirls disappear and the resin turns completely clear, the mixing is done.
Reuse your tools: Wipe off any leftover resin from the mixing stick with a tissue and you can reuse it next time.
Tips:
- Avoid stirring too fast or in different directions — this causes more bubbles.
- For easier and more efficient mixing, an electric mixer is a great tool.
Step 4: Defoaming method
After mixing, let the resin rest for about 2 minutes. Most bubbles will naturally rise and pop.
- Three ways to remove remaining bubbles:
- Pick them off: Use a stirring stick to gently remove surface bubbles.
- Use a lighter: Hold it about 2 inches above the resin and quickly pass the flame over the surface. (Be extra cautious, avoid burning your mold!
- Use a heat gun: Blow over the surface to pop bubbles more evenly and safely.
Tips: How to Deal with Thick Resin in Winter
- Warm water bath : Soak the resin bottle in water at 122°F (50°C) for 5–10 minutes. Use once the resin flows smoothly again.
- Preheater: For a quicker and more efficient option, using a preheater is a great choice.
4. Coloring Techniques
Tips
- Liquid Dye、Mica Powder、Glitters ：Be sure not to add more than 5% of the total resin amount , as too much pigment can affect the curing process.
- Chrome Powder、Chameleon Powder：Using an eyeshadow sponge brush to apply powder results in a more even effect.
5. Curing Time
Once you’ve finished mixing and adding color, pour the resin into the mold and allow it to cure for 8 to 24 hours before demolding.
Tip: Epoxy resin cures through an exothermic reaction, meaning it produces heat as it hardens. The thickness of the resin layer plays a big role in how fast it cures.

6. Quick Cleaning Tips
After finishing your project, cleaning up your workspace is essential. These simple tips will take care of 99% of cleanup tasks.
Hands
① Wipe resin off skin with alcohol or nail polish remover, then wash with soap and water. For tougher residue, rub baking soda on your hands, then rinse.
② Use hand cleaners (like Fast Orange or Gojo Natural Orange) for more effective cleaning.
Desktop
Spray alcohol directly on resin spills and wipe clean.
Mold
①Resin particles: Use tape to pick them up.
②Glitter sticks to molds: Gently press tape over the area to remove them.
Mold Cleaning
Chrome powders or other fine residue: Spray alcohol, then wipe it clean with a tissue.
7. Finished Product Maintenance
Proper care is key to keeping your resin pieces beautiful and long-lasting. Follow these tips:
- Avoid direct sunlight
- Keep away from extreme temperatures
- Clean gently with soft cloths and mild cleaners
Storage
Key Tips: Store in a cool, dry, and well-ventilated area. Protect from direct sunlight to prevent UV aging.
Precautions: Keep away from high heat sources such as heaters or stoves.
Cleaning
Key Tips: Gently clean using a soft cloth or soft brush to remove dust.
Precautions: Avoid abrasive tools that can scratch the resin surface.
Never use high-concentration alcohol, acetone, or nail polish remover. These can fog the surface of UV resin.
Usage of Finished Products
Key Tips: For gifts, home decoration is great.
Precautions: Avoid placing heavy objects on resin items to prevent deformation or cracking. Do not place hot items directly on epoxy surfaces as heat can cause warping.
Repair & Fixing Tips
Key Tips:
① Minor scratches, apply a fresh layer of epoxy resin to cover and smooth the surface.
② Severe damage, sand the surface in stages using sandpaper (from 320 grit up to 5000 grit), then reapply a fresh resin layer for a smooth finish.
Precautions: Do not use strong, corrosive adhesives like super glue for repairs, as they can damage the resin.
