Frequently Asked Questions
General Usage
The mix ratio is 3 : 1 by weight (Resin : Hardener) Eg. 30g of Resin + 10g Hardener.
The resin reaches an initial cure in 12-24 hours, but full curing takes 7 days at temperatures above 30°C.
No, using external heat sources like ovens or heat guns may cause cracking, bubbles, or discoloration. It’s best to let the resin cure naturally at room temperature.
For best results, work in a temperature range of 25-30°C with humidity levels below 60%. High humidity can cause cloudiness, and extreme temperatures may affect curing time and consistency.
Yes, you can mix smaller batches, but ensure you maintain the correct mix ratio by weight for proper curing and performance
Store both components in their original, tightly sealed containers in a cool, dry place away from direct sunlight and moisture. Avoid exposure to air, as it can lead to premature thickening.
Colouring and Customization
Yes, you can color or tint Woodpol Epoxy Art Resin. However, adding color introduces a foreign element into the resin and hardener mixture, which may alter its properties depending on the chemical composition of the pigment. The type of colorant you choose will significantly influence the appearance and durability of your final creation.
Use epoxy-compatible pigments like Woodpol Epoxy Art pigments, mica powders, or alcohol inks. Avoid water-based and solvent-based colorants, as they can affect curing.
Yes! You can blend resin-safe pigments to create unique colors. However, test small samples first to ensure compatibility.
Not necessarily, but materials must be dry and sealed to prevent air bubbles or unwanted reactions.
Use a controlled pour technique and let each color settle slightly before adding another. Layering in separate stages also helps maintain distinct colors.
Applications and Techniques
Ensure your work is free of dust and bubbles before curing. If needed, sand and polish the surface after curing for a mirror-like finish.
Cover your project with a dust-free box or plastic sheet and work in a clean, ventilated area.
Yes, priming is essential. It seals the pores in the wood, preventing bubbles from forming in the resin during pouring. Additionally, the primer layer penetrates the wood, creating a strong foundation for the next resin layer to adhere to securely.
No, sanding is not necessary. Woodpol Epoxy Art Resin is specifically designed for strong intercoat adhesion, so the primer layer does not need to be sanded. However, if you prefer to sand it before applying the next coat, it won’t cause any issues.
Work on a flat, level surface and ensure the resin is evenly spread. Using a bubble-free mixing technique and allowing it to self-level naturally helps achieve a smooth finish.
Yes, multiple layers can be poured. Wait 12 hours between layers for proper adhesion. If more than 24 hours pass, lightly sand the cured layer before adding the next one.
You can either tape off the edges before pouring or sand down drips after curing. For a clean finish, lightly torch the edges after applying the resin.
All About River Tables
Yes, Woodpol Epoxy Art Resin is a versatile product suitable for both small-scale coating and casting projects, as well as large river tables. Its key advantages when used with wood include strong adhesion, minimal heat generation during large pours, extremely low shrinkage, and excellent grindability and sandability
Woodpol Epoxy Art Resin is strong and durable yet maintains a higher degree of flexibility, preventing chipping and cracking during use. Additionally, it has poor adhesion to materials like rubber, silicone, BOPP tape, and certain plastics. You can use these materials as a contact layer when making molds for easy resin release.
At a surrounding temperature of approximately 25°C, you can pour up to 20mm thickness in a single pour, provided the wood is properly primed and sealed. If the temperature is higher, the recommended pour thickness should be reduced accordingly. We suggest conducting trials to determine the ideal pouring conditions based on your environment. At a surrounding temperature of 28 to 30°C, the working time for Woodpol Epoxy Art Resin ranges from approximately 45 to 60 minutes. A lower temperature will extend the working time, while a higher temperature will shorten it.
Note: Begin with small pours to gain full control over how the wood and resin interact. Larger pours can be unpredictable, sometimes leading to unexpected results due to factors that may not be immediately apparent. It’s best to start small until you develop a thorough understanding of the resin, wood, and other influencing elements. For over coating, wait 12 hours after applying the first coat.
1 kg of mixed resin (Part A + B) covers approximately 9 to 11 sq. ft. per mm of thickness.
Example 1:
For a 2.5mm thick clear coat over a 3.5ft × 2ft (7 sq. ft.) canvas, you would need 1.6 to 1.8 kg of resin.
Example 2:
For a tabletop cast entirely from resin, measuring 5.5ft × 3.5ft (19.25 sq. ft.) with a thickness of 1 inch (approximately 25mm), you would need around 47 to 50 kg of resin.
Note: Coverage depends on factors such as the substrate being coated, runoff, and waste. Porous and unprimed surfaces absorb more resin, reducing coverage. Additionally, incorporating materials like wood, stones, or artifacts into the casting can increase coverage while reducing resin consumption.
Troubleshooting
This usually happens due to incorrect mixing ratios, under-mixing, or low curing temperatures. Ensure precise proportioning by weight and proper mixing for at least 5 minutes.
Cloudiness is often caused by moisture or improper mixing. Work in a dry environment and ensure thorough mixing before pouring.
Bubbles can form due to vigorous mixing or trapped air. To reduce them:
1. Mix slowly and thoroughly
2. Let the mixture rest for 10 minutes before pouring
3. Use a heat gun or torch to pop surface bubbles
This happens due to incomplete curing, high humidity, or an uneven pour. To fix it, sand the surface smooth and apply a fresh thin coat of resin.
Ensure the surface is clean, dry, and primed before applying resin. For glossy surfaces, light sanding helps improve adhesion.
Safety and Maintenance
Use isopropyl alcohol or acetone to clean tools before the resin hardens. For cured resin, sanding or scraping may be necessary.
Work in a well-ventilated area
Wear gloves and protective eyewear
Avoid direct skin contact
Keep away from children and pets
Yes, minor scratches can be removed by wet sanding with fine-grit sandpaper and polishing with a buffing compound.
While it has some UV resistance, prolonged outdoor exposure may cause yellowing or fading. Use a UV-resistant topcoat for added protection.
For best results, always follow the recommended instructions, maintain accurate mix ratios, and conduct small test runs before working on larger projects.
