When Should I Apply a Heat-Resistant Topcoat?

Why Choose a Heat-Resistant Topcoat?

Resin surfaces, while beautiful and glossy, can be susceptible to heat damage if exposed to hot cups, pans, or appliances. A heat-resistant topcoat like “Heat Pro” – Flexible Heat-Resistant Glossy Coating helps shield your resin art by absorbing heat and minimising the risk of discolouration or marks. It also retains clarity and adds a durable finish, making it ideal for frequently used items like coasters, tables, and serving trays.

When to Apply a Heat-Resistant Finish

Apply a heat-resistant topcoat if your resin surface will regularly be exposed to hot objects (such as mugs, cookware, or candles). It’s particularly recommended for small to medium surfaces—up to about 0.5 m²—like decorative trays, table tops, and coasters. Ensure your resin base is fully cured and free from acrylics or liquid dyes before application. For best results, follow the product’s mixing and layer thickness instructions, allowing the topcoat to self-level and cure thoroughly—typically 24 hours at room temperature.

Practical Tips for Application

• Apply only to clean, dry, dye-free resin surfaces for optimal adhesion.
• Mix “Heat Pro” carefully following the recommended 100:75 ratio—no additives are needed.
• Spread evenly at about 1 mm thickness; expect coverage of up to 0.5 m² per set.
• Let the topcoat sit undisturbed for at least 24 hours to achieve a flawless, glossy result.
