Concrete Floor Polishing en Mill Valley — Preguntas Frecuentes

Can any concrete floor be polished?+

Most concrete floors can be polished, but results depend on the concrete's condition and age. Soft or heavily damaged concrete may require overlay before polishing.

How slippery is polished concrete?+

Polished concrete has a coefficient of friction similar to standard finished concrete — it is not inherently slippery when dry. When wet, anti-slip treatments can be applied.

How do you maintain polished concrete?+

Dust-mop daily and damp-mop weekly with a neutral pH cleaner. Re-apply guard sealer every 1–2 years for commercial floors, every 3–5 years for residential.
