When colouring polyester resin, your safety should always come first. Understanding and applying practical protective measures can help you enjoy creative projects while minimising potential risks associated with resin and pigments.
Essential Protective Steps
Polyester resin and some colouring additives may release fumes or create fine dust during handling and mixing. Always wear nitrile gloves to avoid direct skin contact, and use a suitable mask, such as a P2 or FFP2 respirator, to protect yourself from inhaling particles and vapours. Eye protection such as safety goggles adds a further safeguard when pouring, mixing, or sanding coloured resin pieces.
- Keep windows open or work outdoors to improve ventilation.
- Avoid eating, drinking, or smoking while working with resins and pigments.
- Dispose of used containers and leftover pigments following local guidelines.
Safe Use of Pigments and Additives
When adding pigments—like the Phosphorescent Pigment – Glow-in-the-Dark Additive for Resin, Paint, and Varnish—pour slowly to reduce airborne particles. Add powders to the resin component before introducing the hardener to promote even dispersion and limit dust. For effect additives such as Resi-Blast, follow product-specific guidance and avoid mixing with bare hands.
When This Matters Most
Attention to safety is especially crucial in confined spaces, when using larger resin quantities, or if you frequently colour resin as part of your work or hobby. Consistently using protective gear can help prevent respiratory discomfort and skin irritation over time.
