Sorry for delay, It actually only took a few evenings... made it all from foam glued... waited 24 hours... then a thin coat of un-sanded grout.. another 24 then a much thicker layer... another 24 then touch ups and knock any unwanted chunks off... then i put about 4 coats of grout sealer on it... and rinsed thoroughly was gonna paint it some but i really liked the way it looked as it was...
