If you have never used epoxy, get someone who has to do it.
Sounds like you remember your 1st experience with it, I sure do.
So do I.
I applied black epoxy grout on a white textured ceramic bathroom floor about ten years ago. It was only about forty square feet of 4"x4" tiles. But the cleanup got way ahead of me.
My wife and 8 year old granddaughter came in the house and got down with me cleaning little black specs from recesses in the tile.
The three of us could still not get it all done before the epoxy cured. There are still black flecks all over that bathroom floor. Fortunately, they almost look like they belong there.
