Let us know how the color and sealant age. I do ferrocement and I am
always on the lookout for permanent coloration. Haven't found it yet.
Finely ground minerals seem best but they also fade.
Yeah, I am concerned, too. I am hoping that the paint pigment entered
enough of the pores to really maintain the color under the sealer.
Have you ever experimented using algae or pond scum, mixed into the
concrete to color it?
