Frequently Asked Questions
How do I know which resin to use for my project?
For thin coats or surface designs, use a clear, medium or high-viscosity epoxy suitable for art. For deep pours, such as river tables, select a purpose-made deep pour resin with an appropriate layer thickness rating.
What’s the best way to avoid air bubbles?
Mix slowly to avoid introducing bubbles, and always use a heat gun or torch to clear them after pouring. Work at room temperature to help bubbles escape.
Can I apply more than one layer of resin?
Yes; allow the previous layer to reach a tacky stage or fully cure (according to instructions) before lightly sanding and pouring the next. This builds depth and strength.
Do I need to seal wood before applying resin?
It’s best to seal porous surfaces like wood with a thin resin coat first. This prevents trapped air bubbles and minimises absorption, producing a smoother final result.
Why has my resin finish come out cloudy or sticky?
This is commonly caused by incorrect mixing ratios, low temperature, or contamination. Double-check your ratios, mix thoroughly, and ensure your workspace is clean and within the suggested temperature range.
How long does resin take to cure fully?
Cure times vary—most surface coatings are tack-free after 12–24 hours, but full hardness may take up to a week. Refer to your product’s specific instructions.
What safety precautions should I take?
Wear gloves, a dust mask, and ensure good ventilation. Avoid skin contact and never inhale resin fumes directly. Clean up spills promptly with disposable towels.
How do I achieve a perfectly smooth finish?
Use a gentle heat source to release bubbles, keep the workspace dust-free, and polish the surface with fine abrasives or a specialist kit after curing if desired.
