"Gap-Filler" Thick Super Glue

Optimized for Bonding Uneven Surfaces, and Extended Working Time.

Starbond® "Gap Filler" Thick is a slower drying (30 seconds), superglue that delivers strong, lasting bonds. The drying time allows for enough time for precise adjustments to be made in bonding applications.

At 2000 cps viscosity, the thickness of this thick ca glue can be described as “honey on a hot summer day,” as the glue is able to flow naturally into voids and gaps. It also doesn't move too quick on angled surfaces. “Gap filler" means that it can not only be used to fill large voids, but also for effectively bonding uneven parts that a thinner glue might not be ideal for.

In woodturning, it’s perfect for gluing brass tubes into wooden pen blanks to wood or other metals to wood. Unlike epoxy, which can be messy and time-consuming, the thick ca glue sets in under a minute—or seconds with the accelerator.

It’s also ideal for glass windows, doors, and other perpendicular or angled surfaces, as it doesn’t drip easily. You can install everything right away without waiting & clamping (like you need for epoxy or wood glue).

A small drop on white birch or balsa wood dries in just 25 seconds. On high surface energy plastics (like ones used in 3D printing) such as PLA, PETG, ABS, and TPU, the medium superglue can bond a bit faster (between 10-20 seconds).

Looking for even faster results? Starbond® Accelerator is perfect if you need the high degree of control from our "gap filler" thick super glue, but want to speed up the bonding time!

Bonding Tip: For smooth surfaces, lightly sand or scuff the area before applying. This increases surface area, resulting in a stronger bond.

  • Fill large gaps and holes
  • Assemble plastic and metal models
  • Form unique finishes by carving, sanding, and feathering

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!
