Epoxy for Beginners- How to Make Adhesive Putty

Making an epoxy adhesive paste or putty is easy and straightforward. In this video we’ll show you how to make a paste or putty for bonding or filleting using epoxy resin and cabosil as a thickener. This is a versatile option for gluing materials together as it makes a putty or paste that won't run off the parts being glued and can be used to glue sheet goods together or to install bulkheads or stringers, or to create a gap filling putty.
Some notes:
The more viscous (thicker) the resin system the less cabosil you will need to add, that said even a low viscosity system can be thickened.

Cabosil (also known as fumed silica or aerosil) - fiberglasssupp...

You can add wood flour.. it's cheaper and works really well.

I had to redo this 3 times. The first times I either added too much Cab O Sil and it dried up or I let it settle in the mixing cup for too long and it dried up. The 3rd time I got it just right and applied the epoxy adhesive putty to what I needed, just before it dried up.

Thanks man. I was looking for a video to make an epoxy adhesive putty that I can use to fill gaps of air for a 16 oz Starbucks tumbler, I'm making an induction heater and using that as a case. I need to cut out a hole to put a mini DC voltmeter on the side of the cap, but the side of the cap is curved. So when I insert the voltmeter in there, I need to apply epoxy in there to fill the gaps and secure it in place.

Hi there,
Great video and thank you.
Is that powder change the shene of the epoxy or still stays glossy when is dry ?

[@card_stock_gliders]

Appreciate the video! Question: Would you recommend against using foam dust (such as from a surfboard shaping room) rather than the manufactured thickening agent?

[@FiberglassSupply]

I don't know that I have tried it. I don't see any reason not to try it.
