With a pH of 1.4 it converts calcium-rich cement and limescale into soluble salts, releasing them from the surface within 3-5 minutes. Inorganic inhibitors limit attack on silicate minerals, so granite (Mohs 7) and basalt (Mohs 7) stay unchanged while up to 200 g\/m² of cement film dissolves.\u003c\/p\u003e\n\n\u003ch2\u003eWhen to Use\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNew \u003ca href=\"\/en-ie\/pages\/stone-granite\"\u003egranite\u003c\/a\u003e kitchen worktops, 1:3 dilution, to strip grout haze.\u003c\/li\u003e\n\u003cli\u003eInterior \u003ca href=\"\/en-ie\/pages\/stone-slate\"\u003eslate\u003c\/a\u003e floors showing limescale rings, 1:3 dilution.\u003c\/li\u003e\n\u003cli\u003eExterior sandstone paving with white \u003ca href=\"\/en-ie\/pages\/problem-efflorescence\"\u003eefflorescence\u003c\/a\u003e, 1:5 dilution.\u003c\/li\u003e\n\u003cli\u003eBasalt stairs after heavy building work, undiluted for cement drops up to 2 mm thick.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-ie\/pages\/stone-terracotta\"\u003eTerracotta\u003c\/a\u003e tiles before sealing, 1:10 dilution to protect soft surface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to Apply\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003ePre-wet the stone until the surface darkens; leave no dry patches.
