We often get called out when other trades with less experience in stone cleaning fail to make a difference which was the case with these Red Jurassic Sandstone Stone steps at a house in Preston which had been stained with paint splashes and years of grime. The customer had tried several solutions to restore these steps including having a go themselves buy applying some Chemicals from a local Tile Shop, however again this didn’t achieve the results the customer wanted so they called us after we were recommended to them.
Burnishing Red Jurassic Sandstone
I took a look at the Sandstone and tested a few methods before deciding to go with a process called Burnishing which involves the application of diamond encrusted burnishing pads. The pads come in a set of four and are applied in sequence from Coarse, through medium, fine and super fine; you need to use a little water to lubricate as you go and also rinse with water between the application of each pad. Naturally due to the tight space I couldn’t use a set of full size pads, only he smaller 6 inch pads which fit a small hand buffer.
Sealing an Indian Sandstone Tiled Floor
The floor was left to dry off overnight and then I returned the next day to seal the whole floor with two coats of our impregnating sealer Tile Doctor Colour Grow. The sealer fills the pores of the stone to prevent ingrained dirt and stains, while also emphasising the natural colours in the stone.
The full process successfully restored the red colour in the Sandstone and have come up quite well considering they are over 300 years old.
