Wednesday''s Ask the Experts question from a cleaning professional on the International Custodial Advisors Network (ICAN) "Ask the Experts" page: I have a three-story atrium with a terrazzo staircase from the first to third floor. What type of sealer would you recommend? I don''t want to use regular floor finish as that will need to be stripped and re-finished periodically. Is there some type of "permanent" sealer that can be used? I am OK with re-applying every year or so, but would much prefer something that I don''t have to strip. I''m not after a "wet look" shine, just something to resist coffee and soft drink spills and make it easier to dust and wet mop.
If you use a penetrating sealer you will not get a wet look shine, but you will get protection from moisture and staining. The sealer is not permanent, and will need to be reapplied every couple of years. Most importantly, it needs to be cleaned with a pH-neutral cleaner that is designed to work with the impregnator.
It may say neutral on the label, but check the Material Safety Data Sheet (MSDS) ...
