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.
