Gorilla Glue Epoxy is a strong, versatile two-part epoxy that bonds well to most countertop materials including granite, quartz, laminate, and wood. It offers a 5-minute working time and sets in 30 minutes, with full cure in 24 hours. Water resistant once cured, it handles minor countertop cracks, chips, and loose edges. However, it struggles with very smooth non-porous surfaces like polished marble unless roughened. Compared to J-B Weld ClearWeld, it is slightly less transparent; compared to Loctite Epoxy Instant Mix, it offers a longer working time. Overall, a reliable choice for most countertop repairs.
How it scores
The good and the annoying
- Very strong bond on porous and textured surfaces
- Easy to mix and apply with included syringe
- Water resistant after full cure
- Slight flexibility reduces stress on repairs
- Not fully clear; dries with a slight amber tint
- Requires surface roughening on non-porous materials
- Can drip if applied too thickly

Gorilla Glue Epoxy is a popular two-part adhesive often recommended for countertop repairs. Our editorial team compared specifications, buyer feedback and key decision factors to evaluate its performance on various countertop materials including granite, quartz, laminate, and wood. We also compared it to other leading epoxies to help you decide if it is the right choice for your project.
Design and Build
Gorilla Glue Epoxy comes in a dual-syringe that dispenses equal parts resin and hardener. The syringe design makes it easy to apply precise amounts without waste. The epoxy itself has a medium viscosity, which allows it to fill gaps up to 1/8 inch without sagging too much. The syringe includes a mixing nozzle that blends the two components as you push the plunger. Some users find that the plunger can be stiff, but overall the design is functional and user-friendly.
Performance on Countertop Materials
We examined feedback from users who applied Gorilla Glue Epoxy on different countertop surfaces. On porous materials like unsealed granite and wood, the bond strength is excellent. The epoxy penetrates tiny pores and creates a mechanical lock. On sealed granite or quartz, light sanding is recommended to improve adhesion. On laminate, the epoxy bonds well if the surface is clean and slightly roughened. On very smooth non-porous surfaces like polished marble or glass, the bond can be weak without abrasion. Compared to J-B Weld ClearWeld, Gorilla Glue Epoxy is slightly less transparent but offers a longer working time (5 minutes vs 2 minutes for Loctite Epoxy Instant Mix).
Ease of Use
Most users find the syringe easy to operate. The 5-minute working time is forgiving for positioning parts. The epoxy is easy to spread with a toothpick or small spatula. Cleanup with isopropyl alcohol is straightforward if done before the epoxy sets. Once cured, the epoxy is difficult to remove, so accuracy during application is important. The syringe can be reused if the nozzle is cleaned immediately after use.
Cleaning and Maintenance
Uncured epoxy can be wiped away with acetone or isopropyl alcohol. Cured epoxy is resistant to water and many household cleaners, but it can be softened by strong solvents like methyl ethyl ketone. For countertop repairs, the cured epoxy can be sanded and polished to a smooth finish, though matching the sheen of the surrounding countertop may require additional effort.
Common Buyer Complaints
Some users report that the epoxy does not cure completely clear, leaving a slight yellow tint on white surfaces. Others mention that the syringe plunger can be difficult to push, especially when the epoxy is cold. A few users experienced the epoxy dripping if applied too thickly. On very smooth surfaces, some reported bond failure without proper surface preparation. Overall, these complaints are relatively rare and often related to application technique.
Conclusion
Gorilla Glue Epoxy is a strong, versatile option for most countertop repairs. It offers good water resistance, a forgiving working time, and a durable bond. While not perfect for every situation, it is a reliable choice for DIYers and professionals alike. Check the current price on Amazon.

You need a strong, water-resistant epoxy for repairing countertop cracks, chips, or loose seams on granite, quartz, laminate, or wood. It is also good for bonding small countertop accessories.
You require a perfectly clear, invisible repair on white or light-colored countertops, or you need to bond very smooth non-porous surfaces without preparation. For those cases, consider J-B Weld ClearWeld or a cyanoacrylate adhesive.
Questions before you buy
Can Gorilla Glue Epoxy be used on granite countertops?
Yes, it bonds well to granite. For best results, clean the area thoroughly and roughen the surface slightly with sandpaper if it is polished. The epoxy fills small chips and cracks effectively.
Is Gorilla Glue Epoxy waterproof?
Once fully cured (24 hours), it is water resistant but not fully waterproof. It can handle occasional spills and moisture, but prolonged submersion is not recommended.
How long does Gorilla Glue Epoxy take to dry?
It sets in 30 minutes and reaches full cure in 24 hours. Working time is about 5 minutes, so you have enough time to position parts before the epoxy starts to harden.
Does Gorilla Glue Epoxy dry clear?
It dries to a clear finish with a slight amber tint. On white or very light countertops, the color may be noticeable. For a truly clear repair, consider J-B Weld ClearWeld.
Can I use Gorilla Glue Epoxy on laminate countertops?
Yes, it works well on laminate. Make sure the surface is clean and dry. Apply a thin layer and clamp if possible. It bonds securely to the laminate surface.
