Looking for a quick and easy tint or dye to mix in Epoxy that hopefully is locally available in the big box store. any suggestions? Trying to fill some defects in walnut and would like to tint/dye the epoxy.

Thanks

Scott!

You will probably find better options at a craft store. Dry pigments are compatible with just about everything. Acrylic paints work pretty well with most things I have tried, but mixing small batches is hard.

Sawdust and epoxy also works, better than sawdust and PVA in a lot of cases.

If you just want to go black and not colormatch, printer toner works. A little goes a long way and it can make a huge mess if a stray breeze comes through. I am not sure if toner will work with a fiberglass/polyester resin, though.

I used to be able to find this stuff at Home Depot when I built custom audio components, but my local HD no longer has it in stock, so I grab at a local boating store:

I have used india ink. You can get it in many colors at Hobby Lobby or Michaels.

Scott, char a piece of scrap with a propane torch and scrape the black off the surface into a small plastic cup, add the epoxy and stir assuming you want black.

I have tinted epoxy with ground up chalk. Yes, blackboard chalk ( or sidewalk chalk)

There is an almost endless amount of stuff you can tint epoxy with, and some things you would never think of work amazingly well (like used coffee grinds for nice deep dark brown). Generally, just stay away from anything that is water based and you should be good. Liquid (paints and inks), stone (powered, crushed, ground), sawdust, metal filings/shavings, various powders (dry pigments, chalk, dry coloring agents, etc…), the list goes on and on… and when in doubt, test a small amount to make sure it will work.

Cheers,
Brad

I use Testor model paint. Readily available, wide variety of colors and inexpensive. A couple drops are enough to tint a pretty decent batch of epoxy.
