Finally finished gluing the medallion-theme paint bucket.
I use a glue labeled "contact cement," which I get locally.
Now for the grouting. I use portland cement mixed with some sand and a black coloring to darken it. Seems to work. My rule is simple: I've got to be able to obtain materials locally. And if I can recycle, all the better.
Looks like we might have some sun today. Fortunate because now I'm going to go pick grapefruits for market.
