Thread: Colouring glue

Epoxy can be tinted with resin tints, even oil based paint tint

Epoxy can also be tinted with food coloring

Hide glue, pva and most water based glues can be coloured with our Non Toxic Water Dyes.

Beware using cedar dye with hide glue as it looks identical to cedar when applied but turns bright lime green when it dries, chemical reaction with the glue takes out all of the red colour.

Used to mix talc, hide glue and water dye to make a gap filling glue which worked extremely well. Same thing works brilliantly with PVA.

Hope this is of some help.

Good to know thanks Neil, I was worried about what ever I used to colour the glue would affect the chemical properties of the glue. Something I'd like to avoid if I'm going to spin this thing around and stand near it

I was originally leaning towards either epoxy or polyurethane for strength and gap filling. I actually like the idea of bright lime green when dried as well. I'd be happy with anything that will provide a strong contrast to the main body wood(s).

Looks like I might be up for a few experiments, food colouring dyes also give me a number of ideas as well but I also need to be careful about the colour leaching into the surrounding wood.

Just remember add very small amounts of tint at a time. Too much can effect properties, it is just like watering it down

Try diggers oxide. All I use for plasti bond, araldite or embedding resin

An almost empty cartridge from a copy machine or laser printer will give you black pigment. Also free.

Thanks for the feedback and suggestions team. As I said, I just didn't want to affect the chemical properties of the glue but it looks like I will be fairly safe on that front if I'm careful.

I find a little bit goes a long way. Black Oxide in epoxy will polish up to give a rich glossy finish.

Haven't noticed any strength issues, but it would be easy enough to do a test; one test joint with and one without.

I got some black oxide this morning so will do some experiments on the weekend and see how it all comes up. Thanks for all your help team.

The experiment is happening. Techniglue with the right hand side joint natural, left hand side coloured with less than a tea spoon of black oxide powder. Will sand back to see how the contrast line looks and then test the joint strength. If both come up ok then I think we have a winner

less than a teaspoon is tons. Matchstick head or ear bud is ample for a 1/2 cup of plastibond for me

Agree with Willy. When adding pigments you add the smallest amount possible, then if colour is not enough, add a little bit more, slowly slowly does it.
