Product Description

Starbond Thick CA Glue is engineered for makers who need maximum control, minimal runoff, and strong gap-filling performance. With a high viscosity of 1500–2000 cPs, this formula behaves like thick syrup—staying exactly where you apply it, even on vertical or uneven surfaces.

The 20–25 second cure time gives you the working time needed for precise placement and clean levelling. This makes Thick CA perfect for knot filling, gap repair, seam bonding, assembly work, turning, crafts, woodworking, plastic repair, and DIY construction.

Compared to thin and medium CA, Thick CA:

• Provides superior gap-filling and structural bonding
• Levels smoothly for cleaner, sand-ready surfaces
• Minimizes absorption into porous woods
• Reduces dripping, running, and unwanted spread
• Allows more control in detailed or vertical applications

Makers use this adhesive for:

Woodworking — knots, voids, cracks, filler builds
Woodturning — stabilizing bowls, handles, blanks
DIY repair — plastics, ceramics, metal bonding
Crafts & hobbies — building, assembly, modeling
3D printing — bridging gaps, fixing seams, structural reinforcement

Thick CA’s slow, predictable cure also provides a clean finish with reduced blooming and strong internal polymerization. When combined with Starbond Accelerator, thick fills cure instantly—great for production work, turning, and deep crack repair.

This Super Glue Pro Kit includes all the accessories you need, plus access to Starbond’s Masterclass video series, helping you achieve clean, professional repairs with strong, consistent results.

Backed by Starbond’s 30-month shelf-life warranty and satisfaction guarantee, this Pro Kit delivers dependable performance for heavy-duty projects and professional results.

Insane…

You could probably glue the Empire State to the Chrysler Building with this. One of the most powerful adhesives I have yet come about… Add the quick setting from the spray and the maneuvering with sanding and filling gaps and it makes this the absolutely perfect glue for any workshop. Both the tick clear and also the Brown medium thick became the main go to for my shop. Could not recommend more !

thick gap filler for hardwood bench

Used thick gap filler (without accelerator) to fill cracks in a tropical rain forest hard wood bench (repurposed rail-road ties). The thick fillers small nozzle was very effective to prevent excess filler on the piece. The thick filler took several subsequent applications to fill the gaps but was "thin" enough to flow into the cracks. I believe the amount flowing into the gaps is much better than an epoxy like west system would have achieved and certainly without a high amount of excess epoxy being applied on the piece.

This stuff is a must.

Whenever I use Starbond CA glue, no matter the purpose, I notice I am always absolutely confident I made the right choice. It does so many things and it does them all superbly. Yes, there are other brands but I always want the best for my projects and in my view Starbond is the best. It is a quality that other brands aspire to.

Your “Gap Filler” Glue

I am a wood carver/ sculptor. This glue, not only kept the cracks from getting any bigger, but filled the cracks AND matched the color of the wood! I wish I had known about it years ago when I started woodworking! Thanks so much!

The Starbond thick gap filler is perfect for my needs. I use it for assembly of numerous parts and pieces for my projects. Unfortunately I rely on this glue far too much for all of my projects. I got to have it.

I got this glue just as I was making some scroll saw bowls. The pieces are very fragile and I had several break while sanding them. How great that I could glue them back together with this glue, and using the accelerator, I could keep sanding with no wait. I highly recommend!

I had a few deep inclusions, splits and knots that I filled nicely using the EM-2000 Starbond gap filler Thick CA Glue. Holds strong, sands flat and easily. Love this stuff!!

Use this and the medium to “tack weld” the strips on a strip built canoe so as to minimize the use of staples. Worked like a charm!

That's awesome to hear, Donald! We are truly happy that you find value in our products.

Works great for filling holes in your project. I’ve used it on cherry and walnut with very good results. Has a very rich look after finishing. These cutting boards I just made had pretty small holes, but I think u get the idea.

Starboard d glue is great. I use it for wood, metal and plastic. It works great for wooden ink pens and wooden bowls.

Hi Michael, thank you for the positive review, and for sharing a picture of that beautiful pen that you made. Your support is truly appreciated!

I love my Starbond! Use it religiously for things most people wouldn't even think of such as CNC project hold down instead of using clamps that just get in the way. There is a product for every purpose and you shouldn't confuse one for the other. Do your research and find the product you need for the task at hand. If you have questions, these guys have a phenomenal support team to answer all your questions very promptly!

Love thin starbond for a finish on small wooded turned items. It’s especially great on wet or oiley woods. (Cedar and Aspen)Also enjoy the extra bottles and tip that come along in the package. Service is great also.

I needed a thick glue to hold in place and not run. The thick was perfect. Thanks for options.

I just want to know how you make CA glue without sticking everything together! :)

I have been using this stuff for many years, first as a woodwork on projects and jigs and then on stones and wood.
