Properly storing unused dyes and epoxy putty ensures their colour quality and usability remain at their best. Taking care with storage protects both your materials and your final project results.
Key Storage Principles
Both liquid dyes and epoxy putty are sensitive to direct sunlight and high humidity. For best longevity, store these products in tightly sealed containers, placed in a cool, dry cupboard or drawer away from windows and sources of heat. This approach helps to avoid premature drying, thickening, or fading that can affect colour vibrancy and workability.
- Keep lids closed tightly after each use to avoid air and moisture ingress
- Choose storage spots that avoid temperature swings, like attics or bathrooms
- Clean the edges of containers before resealing to prevent crusting or contamination
Practical Steps for Storing Colourants and Putty
If you’re using high-coverage colourants like the Colourfun Liquid Epoxy Resin Colourant, even a small bottle can last a long time with proper care. Wipe any excess dye from the bottle rim, reseal immediately after use, and label shades if possible for quick reference. For solid or set-based dyes, keep each container separated and avoid direct contact with damp tools or hands.
When Careful Storage Matters Most
Storing dyes and epoxy putty away from sunlight and moisture is especially important if you buy in bulk, use products only occasionally, or experiment with multiple colours. Fading, clumping, or reduced effectiveness from poor storage can compromise future projects and cause unnecessary waste.
