Epoxy Resin Questions & Answers
Epoxy resin performs best between 17°C and 30°C. Temperatures below this can slow curing and cause cloudiness, while excessive heat can cause overheating or cracking.
Yes. High humidity can cause cloudiness, surface haze, or curing issues. Always work in a dry, well-ventilated environment whenever possible.
Resin is self-levelling and will flow to the lowest point. If the surface is not level, resin can run off unevenly, leaving thin or dry areas.
Yes. Porous surfaces like canvas, MDF, and plywood must be sealed with gesso or acrylic undercoat to prevent resin absorption and air bubbles.
Yes. Epoxy resin can be used clear for top coating or coloured with suitable pigments, inks, or powders to create resin art effects.
Epoxy resin must be measured using the method stated on the product label.
If the label specifies litres (volume), measure by volume.
If the label specifies weight, measure by weight.
Always check the label, as using the wrong method can cause curing failure.
If the label specifies litres (volume), measure by volume.

Always check the label, as using the wrong method can cause curing failure.
Incorrect ratios can result in sticky surfaces, soft curing, or incomplete hardening. Accurate measuring is critical for proper curing.
Mix thoroughly for 3–4 minutes, scraping the sides and bottom of the container. Inadequate mixing is a common cause of curing problems.
Cloudiness during mixing is normal. With proper mixing, the resin will turn clear and streak-free before pouring.
Yes. Allowing resin to rest for 2–5 minutes can help release bubbles and slightly thicken the resin for certain artistic effects.
Do not exceed 5% pigment (by volume or weight, depending on the resin system). Excess pigment can interfere with curing.
You can use transparent pigments, alcohol inks, dyes, pearl powders, and mica powders, depending on the effect you want to achieve.
Bubbles can come from mixing too fast, porous surfaces, or air trapped in pigments. Proper mixing and surface preparation help reduce bubbles.
Use a butane torch or heat gun held about 5 cm above the surface, sweeping quickly.
Do not over-torch, as excessive heat can scorch the resin.
Yes. Resin naturally flows over edges. Many artists mask edges with low-tack tape and remove it once runoff stops but before curing.
Always pour within the recommended depth for your specific resin system. Pouring deeper than recommended can cause overheating, cracking, or curing failure.
Cracking can be caused by excessive pour depth, temperature fluctuations, overheating during curing, or using the wrong type of resin for the application.
A tacky surface is typically caused by incorrect ratios, poor mixing, low temperatures, or high humidity during curing.
Most epoxy resins naturally yellow with UV exposure. Using UV-resistant resin and avoiding prolonged sunlight helps slow this process.
Fish eyes are small craters caused by surface contamination. Always clean surfaces with isopropyl alcohol, avoid touching with bare hands, and wear gloves.
Cure times vary by resin system. Always check the labels on the bottles or contact the supplier for help if you are unsure.
No. Do not move the artwork during curing, as movement can disturb the surface and affect levelling.
Cover the artwork with a raised dust shield such as cardboard or plywood to prevent dust or insects settling on the surface.
Yes. Epoxy resin is suitable for small to medium casting and moulding projects, provided correct pour depths and curing conditions are followed.
Clean tools immediately using orange citrus solvent, methylated spirits, or suitable resin cleaners. Dispose of used brushes safely.
Yes. Epoxy resin should always be used in a well-ventilated area to reduce vapour build-up during mixing and curing.
You should wear nitrile gloves, safety glasses, a suitable respirator, and protective clothing to prevent skin contact and inhalation of fumes or dust.
Wipe off uncured resin immediately and wash with soap and water. Do not use solvents on skin, as they can increase irritation.
Large or deep pours can generate significant heat (exotherm). Always pour within limits, use the correct resin type, and never leave curing resin unattended.
Each resin system is different. Always follow the instructions on the label, and if unsure about ratios, pour depth, or curing conditions, contact the supplier for advice.
