Black Medium-Thick Super Glue

Optimized for Wider Voids and Impact Resistance.

Starbond® Black Medium-Thick Super Glue is a rubber-strengthened adhesive designed for larger repairs and bold accents. This jet-black glue offers exceptional flexibility and impact resistance, making it ideal for heavy-duty bonding and creative projects. Its medium-thick viscosity ensures precise application for filling wider voids and cracks without excessive flow, delivering a strong, seamless bond every time.

How does medium-thick compare to medium?
While both black super glues are rubber-toughened and dry to a jet-black finish, their viscosities cater to different needs. Medium is perfect for filling small cracks and tight spaces, while medium-thick is better suited for larger knots, voids, and more substantial repairs. Choose medium-thick when your project demands a thicker adhesive for durability and gap-filling performance.

Perfect for reconing speakers, securing R/C car tires, or accenting spalted wood, this versatile adhesive can also be sanded and polished to a high-gloss finish. Its durable, flexible nature prevents cracking even in malleable environments, ensuring long-lasting results.

Looking for even faster results? Colored super glues take longer to bond due to the added rubber compound. Use Starbond® Accelerator to speed up curing times, especially for large applications.

Bonding Tip: For a stronger hold, lightly sand or scuff smooth surfaces before applying. This increases surface area and enhances adhesion.

Used For:

  • Adding black accent designs on spalted wood and dark surfaces.
  • Bonding a variety of materials, including wood, metal, glass, rubber, and more.
  • Repairing and filling larger cracks, voids, and knots in woodworking projects.
  • Securing R/C car tires and locking threads.
  • Speaker manufacturing: bonding top plates, cones, gaskets, and other components.
  • Polishing projects to a high-gloss, durable finish.

Great Products

I was introduced to Starbond by a fellow woodworker @retiredwithwood and I couldn't be happier. This is a game changer for my shop when it comes to keeping projects moving and on time. Small imperfections can be quickly and easily fixed allowing me to finish custom projects faster while maintaining quality.

Black Fender Acoustic _ Knee Damage

This Starbond CA is great! Mends, fills, sands and polishes up nicely!
Repair is invisible under almost any possible light source. Tough, attractive results. Just be sure to work in gradual layers to avoid any fogging and micro-voids.

Furniture and Woodturning Uses

I'm using the Medium-Thick black CA glue to fill small crack or holes in hardwood that can occur in highly figured areas.

Also to fill holes, cracks or voids in burl wood before I turn it for pens.

Clear CA would not be appropriate for these purposes.

My answer for everything!

I use Starbond Black for all of my woodworking filler needs. I even fill very large voids with it and it matches black epoxy finishes for small touch up items. I also use the clear for temporarily joining parts for knife making. The only CA glue I use.
