The epoxy should have a consistency similar to Bondo. Step 3 - Enjoy! Once your epoxy's been poured and had time to cure, you'll enjoy your new epoxy project for years to come!

Restore old countertops on the spot, with no demolition necessary!

Review: Works very well, and not as messy as I feared. - Works very well, and not as messy as I feared. It's not exactly powder or dust -- it's hard to describe; maybe kinda like fake snow. Do handle with care, but it not too bad. Good value; one bag will go pretty far. Be aware that it will noticeably lighten the color of your epoxy if you add a substantial amount.
Review: Reasonable price, easy to use - Very effective...stirs in well with the epoxy, has no odor, and doesn't seem to affect the curing time, or noticeably add to the volume.

Works very well, and not as messy as I feared. It's not exactly powder or dust -- it's hard to describe; maybe kinda like fake snow. Do handle with care, but it not too bad. Good value; one bag will go pretty far. Be aware that it will noticeably lighten the color of your epoxy if you add a substantial amount.

### ⭐⭐⭐⭐⭐ Reasonable price, easy to use
*by J***E on January 28, 2025*

Very effective...stirs in well with the epoxy, has no odor, and doesn't seem to affect the curing time, or noticeably add to the volume.

### ⭐⭐⭐⭐ Ok. Lightens your epoxy color.
*by A***L on October 1, 2022*

Works alright; my only real problem is that it changes the color of your epoxy. It's like mixing in white with whatever color you actually wanted.
