If you’re working with Art Pro epoxy resin, knowing the correct layer thickness is essential for a smooth, glass-like result and to avoid problems such as stickiness or uneven curing.
Ideal Thickness for Artistic Pours
Art Pro resin performs best when poured in layers between 1 mm and 10 mm. Staying within this range ensures each layer can cure fully, producing a clear and glossy finish. For most creative projects, such as coasters, trays, or decorative panels, this thickness range offers excellent clarity and surface durability.
Final Glossy Coatings
For a smooth, protective top layer, Art Pro is often recommended for finishes above 1.5 mm. Pouring at or slightly above this threshold creates a strong, high-gloss surface that helps prevent issues like tackiness or uneven cure. If you need a thick, glass-like seal on artwork or surfaces, pouring within the 1.5–10 mm band is your best option.
Practical Pouring Tips
- Measure the resin and hardener carefully following the 3:2 mixing ratio.
- Pour in layers within the 1–10 mm range; avoid going thicker in one go to ensure consistent curing.
- Let each layer cure (usually 12–24 hours) before adding the next for complex, multi-layer artwork.
- If polishing is needed after curing, consider using tools and products specifically designed for resin, like the Epoxy Polish – Epoxy Resin Polishing System for a flawless finish.
When Thickness Matters Most
Sticking to these recommended layer thicknesses is particularly important for functional items or pieces exposed to regular use, such as serving boards or tabletops. Proper thickness reduces the risk of soft spots and helps maintain surface strength and brilliance.
