Sandstone is generally a rough textured surface requiring regular cleaning and sealing to keep it looking good, I’ve also known customers to complain that the rough texture can shred mops during regular cleaning. This Sandstone tiled floor installed in a house in Lancaster was no different and so with the owner’s approval we decided to gently grind the sandstone to produce a smoother more manageable surface. At Tile Doctor we refer to this process as Milling and it’s especially useful for flattening a raised surface between tiles often called lippage.
Milling and Sealing a Sandstone Tiled Floor
As far as I know Milling was developed at Tile Doctor to basically smooth down a rough textured surface to make it easy to clean, seal and maintain; it’s a one off process and is akin to sanding down a rough piece of wood with sandpaper. We don’t use sandpaper for this purpose but diamond encrusted burnishing pads which like sandpaper come in different levels of coarseness. Milling actually reveals more of the character in the surface of the stone which is further enhanced during sealing for which recommend the use of a matt finish sealer such as Tile Doctor Colour Grow or if there is still a bit of texture in the stone we recommend the use of a topical sealer such as Tile Doctor Seal and Go which also leaves a nice low sheen finish.
The customer was on holiday when the work was done but was so pleased with the effect of the milled Sandstone floor she rang me up personally to say thanks and left the comment below on the Tile Doctor feedback system, she was experiencing a lot of trouble cleaning this floor and we managed to resolve that and still keep the texture and character of this beautiful floor.
“Total transformation of our floor. Can’t quite believe the results. No mess and an amazing result. Thank you v much
