'Color shading' on grout thinner than 1/8'? What is this?
My tile guy suggests not doing grout lines thinner than 1/8" because of what he calls "color shading" if grout lines are thinner. What on earth does this mean? I thought it was more ideal to have thinner grout lines. He wants to use sanded grout with a sure color or color enhanced sanded grout. Is he on the right track? thanks.
