GENERAL USAGE
Always measure epoxy components by weight using a precise digital scale. This ensures the chemical ratio remains accurate for proper curing. If a scale isn’t available, follow the volume-based ratio strictly as mentioned on the label.
Kitchen cups are not calibrated for resin accuracy. Use graduated containers or digital scales to ensure proper mixing. Inaccurate measurement can lead to soft or uncured results.
 An incorrect ratio can cause the resin to remain sticky or not cure at all. The chemical balance between resin and hardener is critical. Always mix in the exact ratio specified for your system.
No. Once mixed incorrectly, epoxy cannot be fixed by remixing. You must remove the failed mixture and start fresh with new material.
Pot life is the usable working time after mixing resin and hardener. It depends on ambient temperature and batch size. After pot life, the epoxy begins to gel and becomes unworkable.
Full cure time ranges from 24 to 72 hours depending on the type of epoxy, ambient temperature, and thickness of the pour. Thin layers cure faster than thick ones.
Yes, gentle heat can speed up curing. Ensure temperatures don’t exceed safe limits or you may cause yellowing, warping, or cracking.
This is often due to incorrect mixing ratios or inadequate mixing. Always mix thoroughly and avoid using expired material.
Ideally, epoxy should be used at 22–28°C with controlled humidity. Too cold slows curing, while too hot can cause fast gelling and bubbles.
Epoxy undergoes an exothermic reaction when mixed. Large batch sizes and confined containers trap heat, accelerating curing and increasing risk of overheating.
MIXING & HANDLING
Stir slowly and thoroughly with a flat-edged stick, scraping the sides and bottom. Mix for at least 3–5 minutes depending on the batch size.
Yes, for large batches. Use low-speed mixing (under 300 RPM) to avoid air entrapment. Always finish with a manual stir.
Use clean plastic or silicone containers. Avoid metal or glass, as they may react or retain heat.
No. Paper and foam can absorb the chemicals or melt. Always use epoxy-safe containers.
No. Paper and foam can absorb the chemicals or melt. Always use epoxy-safe containers.
Yes, but maintain the exact ratio. Use a digital scale and mix thoroughly. Eyeballing is not recommended.
Mix slowly, allow the mix to rest for 5 minutes, and use a heat gun or torch to remove surface bubbles.
Not always. For highly detailed or clear projects, vacuum degassing can be helpful, but careful mixing often suffices.
Yes, but only use pigments compatible with epoxy systems. Avoid water-based or unknown substances.
Yes, but ensure they are clean, dry, and placed slowly to avoid bubble traps. Heavy items may sink without proper technique.
The mixture should appear uniform without streaks. Incomplete mixing often results in tacky or soft spots.
APPLICATION & SURFACES
Yes, let the first layer become tacky or sand if fully cured before adding the next. This ensures bonding.
Only if the formulation supports deep pours. Otherwise, pour in multiple thin layers to avoid overheating and cracking.
Epoxy bonds well with wood, metal, stone, concrete, ceramics, and most plastics. Always clean and sand surfaces beforehand.
No, epoxy does not bond to silicone, wax, or oily surfaces. These materials are used as release agents.
Yes. Sanding helps mechanical adhesion. Clean all dust and debris before applying epoxy.
Yes, but ensure the coating is fully cured and lightly sanded. Compatibility should be tested first.
Regular epoxy may sag. Use thixotropic (non-sag) formulations for vertical or overhead applications.
Yes, high humidity can cause blushing or cloudiness. Use dehumidifiers or condition the room if needed.
Only if UV protection is applied. Standard epoxy may yellow under sunlight. Use a UV-stable topcoat for outdoor use.
Yes, fully cured epoxy is waterproof and moisture resistant. It’s used widely in marine, plumbing, and flooring applications.
CURING & FINISHING
Yes, heat guns help remove bubbles and accelerate curing. Do not overheat or keep it too close to the resin.
Only if the product is rated for post-curing. Otherwise, it’s risky and may deform or yellow the resin.
This can be due to moisture (blushing), trapped bubbles, or incompatible additives. Control environment and materials.
UV exposure, over-curing, or impurities can cause yellowing. Store epoxy properly and use stabilizers where needed.
Yes, you can wet sand with fine grit and then buff with polishing compounds to achieve a glossy finish.
Yes, use progressive sanding from coarse to fine grits. Always wear a mask to avoid inhaling dust.
Yes, once fully cured it can be machined with standard tools. Use slower speeds to avoid cracking.
Yes. If previous coat is fully cured, sand it lightly and clean before applying the next layer.
Yes, but sanding is required for adhesion. Use paints compatible with hard, glossy surfaces.
Cured epoxy is difficult to remove. Use mechanical methods like sanding, scraping, or grinding.
SAFETY & STORAGE
Uncured epoxy can irritate skin and eyes. Always wear gloves, goggles, and work in a ventilated area.
It’s safer to wear a mask, especially during sanding or if working in poorly ventilated areas. Vapors can cause irritation.
 Wash immediately with soap and water. Avoid solvents. Prolonged contact can lead to dermatitis or allergies.

Yes, repeated exposure may lead to skin sensitization. Always wear proper protection.
Most epoxies are not flammable, but always check the safety data sheet. Cured resin is generally fire-resistant.
Keep containers tightly sealed in a cool, dry place away from sunlight and humidity.
Shelf life is typically 12–24 months. Check product label and avoid using old or crystallized resin.
Only certain epoxies are food-safe. Unless certified, do not use near food contact surfaces.
 Yes, freezing can damage components. Store indoors above 10°C to maintain performance.
Gloves, goggles, long sleeves, and a mask or respirator are recommended for safety.
TROUBLESHOOTING & TECHNICAL
Likely due to incorrect ratio, under-mixing, expired material, or cold temperature. Discard and remix properly.
Mixing too fast, pouring over moisture, or trapped air causes bubbles. Stir gently and use heat to remove.

Poor surface prep or contamination like oil or dust can lead to failure. Always sand and degrease before application.
Likely due to humidity, incompatible additives, or improper mixing. Control environment and use compatible materials.
Yes. Old epoxy may thicken, separate, or crystallize. Avoid using past-expiry material.
A surface film caused by moisture during curing. Remove with warm water and mild detergent before recoating.
No. Only use recommended epoxy thinners. Water and alcohol can ruin the chemical reaction.
Most epoxies are rigid. Use specialized flexible systems for rubber or soft materials.
Slow-cure epoxies offer longer working time and deeper pour capability. Fast-cure sets quicker but may limit working time.
