Is odour a factor when choosing resin for visible projects?

When creating decorative or functional pieces with resin, especially in indoor or highly visible spaces, the odour during application and curing can play a crucial role in your choice of material.

Understanding Resin Odour

Resins vary significantly in terms of smell during application and curing. Polyester resins are known for their strong, chemical odour, which can be overwhelming—especially in poorly ventilated environments. This isn’t just a brief nuisance; the scent can linger for the duration of the curing process and even after the item is set. Epoxy resins such as “Icrystal” are formulated to be odourless, making them a more pleasant choice for indoor use or where air quality is a concern.

Choosing the Right Resin for Indoor and Display Projects

If you’re working on projects destined for homes, galleries, offices or anywhere people gather, the odour released while the resin cures becomes a serious factor. Strongly-scented polyester resins may cause discomfort, so many creatives and DIY enthusiasts opt for odourless epoxy alternatives. Odourless epoxies allow you to work comfortably without lingering chemical smells, providing a more user-friendly experience for both the maker and those who encounter the finished piece.

When Does Low-Odour Resin Matter Most?

Indoor use: When ventilation is limited, a low-odour resin prevents unpleasant fumes.
Inhabited and display areas: For items placed in lounges, offices, or public spaces, an odour-free result ensures comfort for everyone nearby.
Prolonged projects: When you’ll be working for extended periods, low-odour resins help maintain a pleasant workspace.
