Dandy's White/Grey Limestone is an excellent choice for offering a uniform finish to an area on a budget, which makes it an excellent choice if you are trying to rent or sell your home and need to clean it up a bit for pictures and viewings. This is a chipped aggregate that has been graded to around 10mm or 20mm down over piano wires it can arrive dusty, but after it has been rained on and driven or walked on a little, it will easily wash off to grey.
