What is Art Resin?
Art resin, also known as epoxy resin, is a two-part liquid polymer that hardens into a clear, glossy, and durable finish. It's widely used in art projects, including canvas coating, river tables, jewelry making, and decorative pieces.
The resin consists of two components: Part A (resin) and Part B (hardener). When mixed in the correct ratio, they undergo a chemical reaction that transforms the liquid into a solid, glass-like surface.
How to Calculate Resin Needed
To calculate the amount of resin needed, you need three measurements:
- Length of the surface to be coated
- Width of the surface to be coated
- Desired thickness of the resin coating
The formula is: Volume = Length × Width × Thickness. For resin, 1 cm³ equals approximately 1 ml of mixed resin.
Common Resin Thickness Guidelines
| Application | Recommended Thickness | Notes |
|---|---|---|
| Canvas coating (seal coat) | 1-2 mm | Thin protective layer |
| Canvas coating (flood coat) | 3-4 mm | Thick glossy finish |
| River tables | 10-50 mm | Deep pour resin recommended |
| Coasters | 5-8 mm | Multiple pours may be needed |
| Jewelry | 2-5 mm | Thin layers work best |
| Geode art | 5-10 mm | Build up in layers |
Resin Mixing Tips
- Always follow the manufacturer's specific mixing ratio
- Measure accurately using a digital scale for best results
- Mix slowly for 3-5 minutes to avoid introducing bubbles
- Scrape the sides and bottom of the container thoroughly
- Work in a well-ventilated area with proper safety equipment
- Maintain room temperature between 70-75°F (21-24°C) for optimal curing
- Use a torch or heat gun to remove surface bubbles after pouring
- Cover your work to prevent dust contamination during curing
Safety Considerations
- Always wear gloves, safety glasses, and protective clothing
- Work in a well-ventilated space or use a respirator
- Keep resin away from heat sources and open flames
- Read and follow all manufacturer safety instructions
- Store unmixed resin in a cool, dry place away from children and pets
- Dispose of unused resin according to local regulations
- Have paper towels and isopropyl alcohol on hand for cleanup
Frequently Asked Questions
- How much extra resin should I order?
- It's recommended to order 5-10% more resin than calculated to account for spillage, waste, and measurement errors. For larger projects, having extra resin ensures you can complete the project even if some is wasted during mixing or pouring.
- Can I pour thick resin layers all at once?
- Most standard epoxy resins should be poured in layers no thicker than 1/4 inch (6mm) to prevent overheating and cracking. For thicker pours, use deep pour resin specifically designed for thick castings, which can be poured up to 2 inches (50mm) at once.
- What is the difference between 1:1 and 2:1 mixing ratios?
- The mixing ratio indicates the proportion of resin (Part A) to hardener (Part B). A 1:1 ratio means equal parts of each, while 2:1 means twice as much resin as hardener. Always follow your specific resin's instructions, as different brands have different ratios.
- How do I convert between ml and grams for resin?
- Epoxy resin has a density of approximately 1.1-1.2 g/ml, meaning 1 liter of resin weighs about 1.1-1.2 kg. However, it's best to measure by volume (ml) for mixing ratios rather than weight, as Part A and Part B may have different densities.
