Gorilla 2 Part Epoxy, Clear Epoxy 0.85 Ounce Syringe
Features: Dries clear for a clean, durable finish; 5-minute set time allows quick adjustments; also functions as a gap filler for uneven or vertical surfaces. Best for quick household repairs or automotive tasks where transparency matters. Limitation: small syringe capacity may require multiple applications for larger projects.
Best For
- Small repairs where a fast, clear bond is needed
- Projects requiring precise placement before cure
J-B Weld ClearWeld 5 Minute Set Epoxy Syringe
Features: Clear, quick-setting 5 minutes; 1:1 mix via a syringe; resealable cap to prevent drying. Works on metal, tile, most plastics, ceramic, glass, and wood. Best for: projects needing a see-through, strong bond with minimal setup. Caution: cure time is short—work quickly to reposition before full set.
Best For
- Glass-to-glass or glass-to-metal repairs where appearance matters
- Small construction or hobby projects with tight timelines
Superclear Liquid Glass Deep Pour Epoxy Resin
Features: Deep pours from 2 to 4 inches per lift, ideal for river tables and large glass molds; crystal-clear, bubble-free finish with minimal torching; durable, scratch-resistant cure. Best for: large-scale glass projects that require depth and a high-gloss surface. Limitation: deep pours demand careful temperature control and layered curing.
Best For
- River tables, live-edge wood with glass, large molds
- Surfaces that must remain crystal clear and glossy
TotalBoat 4-Minute Epoxy Glue, Clear 2 Part
Features: Dries clear and sets in 4 minutes; cures in 4 hours, handling strength quickly; bonds fiberglass, metal, wood, glass, ceramics, and more. Best for: fast, reliable bonding where multiple materials are involved. Caution: not suitable for polyethylene or polypropylene substrates.

Features: Artisan-approved clear epoxy with low odor and no VOCs; bubble-free formula reduces surface imperfections; food-safe epoxy resin suitable for crafts like coasters and jewelry. Best for: DIY art projects and food-safe pieces with a glass-like finish. Limitation: ensure proper ventilation during use due to odor reduction claims and confirm food-safety guidelines when using on consumable pieces.
Buying Guide: Clear Epoxy For Glass
What should you consider when choosing a clear epoxy for glass? Here are practical questions and answers to help you compare options.
What cure time fits my workflow?
Quick-set epoxies (approximately 4–5 minutes) are ideal for small repairs or projects needing rapid progress. Deeper pours or large pieces may require slower systems or multiple pours to avoid heat buildup and ensure clarity.
How clear is the cure and does it yellow over time?
Look for formulations advertised as crystal clear with low yellowing. Some kits are designed specifically to resist yellowing during extended use or under UV exposure, which is important for glass-display items and countertops.
Is the epoxy safe for glass-to-glass bonds?
Epoxies labeled “clear” and designed for glass or mirror bonding typically perform well on glass-to-glass joints. Confirm substrate compatibility (glass, ceramic, metal, wood, plastic) and note any cautions about applying to certain plastics.
What about deep pours or large surfaces?
Deep-pour epoxies are designed to minimize bubbles and support large, single-lift casts. If you’re making river tables or large resin slabs, choose a product that supports 2–4 inch pours without excessive torching or heat buildup.
Is there any safety or odor concern?
Some resin kits have low odor or food-safe claims. If you’re working in a small space, consider low-odor formulas or ensure good ventilation. Always follow handling instructions and use PPE as directed.
How do I handle gaps and uneven surfaces?
Epoxies with gap-filling properties are helpful for bonding uneven surfaces or vertical applications. For glass projects with gaps, choose a formula that lists gap-filling capability in its features.
FAQ
- Q: Can clear epoxy be used on glass tabletops? A: Yes, many clear epoxies are formulated for glass and other rigid materials, delivering a transparent, durable bond when applied correctly.
- Q: How long does it take for epoxy to cure on glass? A: Cure times vary by product; some set in minutes and cure within hours, while others may fully cure over 24 hours.
- Q: Do epoxy resins require mixing? A: Most two-part epoxies require a precise 1:1 mix ratio, followed by thorough stirring before application.
- Q: Are clear epoxies safe for food-contact surfaces? A: Some kits are labeled food-safe; always verify the product’s safety guidelines and use only as directed for food-related items.
- Q: Can epoxy be sanded or polished after curing? A: Many epoxies can be sanded and polished for a smooth finish, but check the product’s recommendations before proceeding.
