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 Superglue 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.

Great product!

Worked perfect for my custom wood plaques. The tips made attaching small pieces a breeze.

Starbond CA glue

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.
