Which grout is known for heavy chemical resistance and stain resistance?

• A. Cement grout
• B. Epoxy grout
• C. Latex grout
• D. Drywall grout

Answer: (B)

The main idea here is how grout chemistry affects resistance to chemicals and stains. Epoxy grout uses two-part epoxy resins that cure into a hard, dense, non-porous matrix. That continuous, non-porous structure makes it highly resistant to common cleaners, acids, alkalis, and dyes, so spills stay from penetrating the grout and causing discoloration. Cementitious grout, on the other hand, is basically cement-based and remains porous unless an impregnation sealer is used; liquids can soak in and cause staining or chemical damage over time. Latex-modified grout improves on plain cement grout’s performance, but it’s still cement-based and porous enough that strong chemicals or repeated spills can lead to staining and degradation. Drywall grout isn’t a standard tile grout type for actual installations, so it doesn’t apply in this context.
