Acid-related surface damage such as dull spots or light marks.
Etch marks on concrete appear as lighter patches, dull areas, or surface roughness caused by chemical exposure. Because concrete contains cement, it is highly reactive to acids and certain industrial cleaning agents. What’s Happening Concrete is made from cement, sand, aggregate, and water. The cement component contains calcium compounds that react chemically when exposed to acidic…
Etch marks on terrazzo appear as dull spots, lighter patches, or surface roughness caused by chemical exposure. The severity and cause depend on whether the terrazzo is cement-based or epoxy-based. What’s Happening Terrazzo is made from decorative stone chips embedded in either a cement binder or an epoxy resin binder. Cement-based terrazzo contains calcium and reacts…
Etch-like marks on quartz appear as dull spots, lighter patches, or cloudy areas that resemble etching on natural stone. Although quartz does not chemically etch like marble or limestone, certain chemicals can damage the resin binders in engineered quartz and create similar surface changes. What’s Happening Quartz countertops are made from crushed natural quartz bound together…
Etch marks on limestone appear as dull, lighter, or slightly rough areas caused by contact with acidic substances. Because limestone is calcium-based, it is highly sensitive to acids commonly found in household products and food. What’s Happening Limestone is composed primarily of calcium carbonate, the same mineral family as marble and travertine. When an acidic substance…
Etch marks on granite are uncommon but possible, depending on the stone’s mineral composition. While granite is generally more resistant to acids than marble or travertine, certain types of granite can still show dull spots or surface changes after exposure to acidic substances. What’s Happening Granite is made up primarily of quartz, feldspar, and other minerals…
Etch marks on travertine are dull, lighter-looking spots or rings that can appear after contact with acidic liquids. They’re common on travertine because it contains calcium-based minerals that react with acids, even when the spill seems mild. What’s Happening Travertine is a natural stone made largely of calcium carbonate. When something acidic—like citrus, vinegar, wine,…
Etch marks on marble appear as dull spots or rings caused by contact with acidic substances. Unlike stains, etching alters the surface of the stone itself, affecting its texture and light reflection. What’s Happening Dull spots or rings caused by acidic substances like citrus, wine, vinegar, or certain cleaners. These marks aren’t stains — they’re…
