Question

I have a 3 story atrium with a terrazzo staircase from the 1st to 3rd 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 & soft drink spills & make it easier to dust & wet mop.


Answer

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 important, 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 MSDS to ensure a pH of 7. Otherwise, you will remove the sealer protection much too soon.
