← Back to How do you resin glass objects?


Epoxy resin can transform glass with a glossy, protective layer or creative effect. But is every glass object suitable for resin? Let’s explore the essentials for a successful glass-resin project.
Suitability of Glass for Epoxy Resin
Most glass objects can be coated or encased in epoxy resin, provided the surfaces are thoroughly cleaned and dried. Glass is naturally non-porous, but oils, fingerprints or dust can make resin adherence unreliable. Carefully degrease with a suitable glass cleaner or isopropyl alcohol to remove any barriers before beginning your project.


How to Prepare Glass for Resin Application
- Clean thoroughly: Wash the glass in warm soapy water to remove surface dust and grease.
- Degrease: Wipe down with alcohol or glass cleaner for a residue-free finish.
- Dry fully: Moisture can affect resin adhesion—ensure all surfaces are bone dry.
- Consider edges or tricky shapes: Mask edges with tape if you want clean lines, and ensure items like vases are supported so resin does not pool awkwardly.
Choosing the Right Epoxy Resin for Glass
For decorative or protective glass coatings, opt for a clear resin that’s designed for layering or coating. Products such as “Icrystal” Clear Epoxy Resin offer exceptional clarity and are odourless, making them suitable for indoor tasks. If you’re casting over glass or working with thicker layers or artistic effects, make sure the chosen resin is appropriate for the desired thickness and finish.

When Careful Preparation Matters
Adhesion issues arise if glass isn’t properly prepared. This matters especially for functional items like tabletops or decorative glassware, where a resilient, clear finish is vital for longevity and appearance.
