I have a friend who had a patio poured and dyed green. Supposedly the job was done properly, and the concrete was dyed all the way through. No dice.
She failed to apply sealer to it last year, and now apparently the dye has faded out of the surface. Several people she has contacted have said it cannot be re-dyed.
I happen to think if there is anyway this can be accomplished, some of you among the teeming millions will know a way.
Btw, I already sugested a coloured epoxy coating, readily available to do it yourselfers, but she doesn’t want the uniform opaque colour. She has a terrazzo effect, and wants to keep it.
Any suggestions?
