How to identify whether Curb staining? Curb belong granite stone, the color of the stone itself, there are many, but sometimes we find some Curb particularly bright colors, looks very unnatural, especially in the gloss that regard, this type of Stone is a stone-colored dye inferior. How to identify the kind of stone that it? The following small series will introduce curbs distinguish staining methods: 1, the fracture dye penetration level billboards, but sometimes need to see the milling tool. 2, Curb general quality staining is not good, large porosity, high water absorption, Baoding road calculus, we can use percussion method can distinguish natural stone is a clear, crisp sound. 3, generally are coated with oil staining Curb surface to increase the gloss of the stone, and all have a grease stain on the back of the stone sense; 4, painted curbs gloss film may seem high, but the thickness of the coating is not enough , easy to wear, to the light we can see scratches. 5, waxed surface of the stone, we used a lighter roast, you can see its true colors. 6, we can also use toilet paper to wipe the surface of the curb, fall color if the note is stained. Curb crystal surface treatment principle is the use of crystal hardening agent plus brush machine stone surface friction, under the chemical and physical dual role of the stone surface of the crystal surface to form a hard layer hard and compact, so easily damaged stone surfaces sell road calculus, also easy to stick dye stains. Crystal surface treatment did not change the structure of the stone, it is not coated with a layer of mulch, road calculus size, so the road calculus, does not change the texture of the original stone. Curb After the crystal surface treatment, stone surface molecules are more compact, significantly improved gloss, stone surface more beautiful, more noble.
