This Black Granite sink countertop was damaged by a cleaning company during an end of tenancy clean at a rental property in Clapham South London. Granite is a very robust stone, but acidic cleaning products will etch it and damage the factory polish thereby ruining its appearance.
Restoring the Appearance of a Granite Countertop
To bring back the appearance of etched Granite we have found its necessary to use various grits of polishing pads and handheld blocks which are made from industrial diamonds. The larger 6-inch pads fit into a handheld buffer which helps to make the process easier.
I started though with the application of a coarse 200-grit hand block to remove the deeper etching from the damaged areas and then moved on to refinishing the surface with the diamond burnishing pads of increasing grits. Water is used to lubricate the process and remove the fine slurry that is generated. I finished on a 3000-grit pad which is applied dry with only a small amount of water to really bring up the polish and ready for sealing.
Sealing a Granite Countertop
To protect the Granite a couple of coats of Tile Doctor Colour Grow sealer was applied. This sealer is an impregnator which soaks into the pores of the stone giving long lasting protection, it’s formula also contains a colour enhancer which brought out the dark Black colours in the Granite.
The property was now ready for the new tenant.
