Mosaic Workshop has stocked these coloured grouts from Instarmac for some years, but they have now been discontinued and we haven't been able to get further stock. The remaining stock is for sale below and as this runs out we'll be offering grout in similar colours from well-known supplier, BAL. These are new generation grouts with better flexibility, faster curing times and better eco-credentials. Goodbye Instarmac and hello BAL!
