A Guide to Sealing and Resealing Natural Stone

Natural stone adds timeless beauty to your spaces, but to preserve its luster and durability, sealing is often essential. Different types of natural stone have unique characteristics, and not all require sealing. Here's a guide from Colorado Stone & Tile Care to help you understand which natural stones need sealing and signs indicating it's time for resealing.

Now that we understand which types of stone benefit the most from regular sealing, let’s take a look at some signs that signal that it is time for you to reseal.
