Travertine patio pavers are another perfect example of an industry so full of misinformation. Customers are often confused about whether to seal or not and what sealer to use. Currently, many industry professionals claim travertine pavers last forever and do not need to be sealed. This is false! I was one of the first travertine restoration contractors to say travertine floors inside do not need to be sealed, but it’s still common that the industry says the contrary.
