To seal or not to seal?

I am looking for information on care and maintenance of travertine floors, includind sealing information.  Would this be in your article "to seal or not to seal"?  Is there another article that applies?

 

Also, I have Bianco Catalina floors and counters in my daughter's bathroom.  Would your "to seal or not to seal" address this area as well, or do I need to get "preservation of residential stone floors" as well.

 

I have purchased products from you in the past, and will continue to do so in the future.  I

thought I read that article(s) were free for customers, is this correct?

 

Thank you.
