"Gap-Filler" Thick Super Glue

Description

Starbond® "Gap Filler" Thick is a slow-setting super glue with a 30 second set time that is ideal for bonding uneven parts and filling large voids. At 2,000 cps viscosity, the thick ca glue flows like “honey on a hot summer day”—controlled, gap-filling, and perfect for bonding applications on angled surfaces without dripping.

Whether you're gluing brass tubes into pen blanks, bonding glass, or working with plastics like PLA or ABS, this formula gives you time to adjust before setting—no clamps or mess like epoxy.

Need speed? Pair with Starbond® Accelerator for an instant cure.

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.
