Epoxy ?

[Trey1984]

First and foremost this is my first time working with epoxy! With that said I'm making some charcuterie boards and filling small voids. One of the boards had a huge knot and it had to be removed. You can see in the pic how big the hole is. My question is what do I need to do/use to cover the bottom of the hole so the epoxy won't leak out? I'm going to put small bead of glue with hot glue gun around the top. I'm also going to color it black. What is best to use mica powder or the liquid dye?. The name of the epoxy is clear pour epoxy resin. Something ordered of Amazon. Don't know if that makes difference. Thanks in advance

Tuck tape or foil tape can seal the bottom. Or hot glue a scrap piece to the bottom.

I used the liquid dye on our countertops. Seemed to work fine.

clear packing tape works great for closing the back of the hole. Use whatever you want to color the epoxy. Coffee grounds make a nice dark filler.

I just use blue masking tape. I'd prob go for the micah powder as dye as I'd want maximum strength and idk how much the liquid dye affects the chemistry.

I have used packing tape. Be sure you get the edges sealed tight.

I use tyvek house wrap tape from big box stores. I like eye candy powder tint. You may want to seal the sides and seams with a light brushing of epoxy first which will help prevent leaks and bubbles.

Cleanest way I've found that minimizes clean up and leaves bottom smooth and ready to sand--Cover hole with piece of wax paper, then tape it down with packing tape. Go overboard on taping and sealing around the edges.

I have had good success with Transtint dyes. Added benefit is that you can also use that for coloring your finish, not just epoxy. Make sure you add some sort of filler to the epoxy like sawdust, it makes it less plasticy and dries harder. Coffee grounds, cocoa powder, paprika, I've used lots of food items for coloring as well and they work just fine, but dyes are easier/ more repeatable. Advanced techniques include mixing the epoxy, add dye, mix, then swirl in coffee grounds/ cocoa powder etc. to make the color more natural/ less uniform. Same works with using sawdust lighter/ darker than the wood you're filling.

I’ve used artists oil paints with good success. I’ve also used fountain pen ink in the past.

 

[Berta]

I have added cheap mica powder (dollar store eye shadow), also alcohol ink.
I have also added coffee grounds (dry) and glitter.

I’m not opposed to epoxy if it adds character but I would not limit your options. Consider a plug or an inlay with either matching wood or contrasting.

Those that have used coffee grounds to tint. Do you use fresh coffee grounds or get your coffee out of them first

 

[smallboat]

Dry, in my case. Either would work if thoroughly dry

I prefer to get fresh beans (Sumatra/ Kenya blend) and grind them on the espresso setting for Walnut, drip coffee for Wenge

It doesn't really matter, used grounds are fine but you have to let them dry first. Given that you only need half a teaspoon for the typical job, it's not really wasting coffee.
