How to Prevent Yellowing in Resin Projects

← Back to What do I do with 3 kg of resin?

Resin yellowing over time is a common challenge, especially for projects that are meant to showcase clarity and bright colours. By choosing the right supplies and using effective care techniques, it’s possible to keep your resin creations bright, clear and beautiful for years to come.

Select a Resin with Built-In UV Protection

The resin you choose largely determines how well it will resist yellowing. Opt for products formulated with strong UV filters, as sunlight is a leading cause of discolouration. For example, EpoxyTable 5-Five is designed specifically for deep pours and includes integrated UV protection, helping to reduce the effects of sunlight exposure. The same principle applies to resins like Trasparente and Icrystal, which are also made with UV-inhibiting properties to guard against early yellowing.

Care Tips: Protect Your Finished Pieces

No matter how good your resin is, care after curing makes a difference. Keep your finished works away from constant, direct sunlight and excessive heat where possible—this is especially important for decorative items and furniture. Indoors, consider positioning pieces away from windows or areas of regular sun exposure. For added caution, lightly dust and clean resin surfaces only with gentle, non-abrasive cloths to preserve clarity.

When This Matters Most

Clear tables, countertops, and furniture require extra protection due to their exposure.
Jewellery, coasters, and decorative items with embedded art or vibrant colours benefit from careful resin selection and display to stay vivid.
