Professional stone and tile installers have skin in the game when it comes to understanding what causes moisture discoloration on marble and other natural stone installations, especially white Carrara marble floors.

Pavlo “Pasha” Starykov of Star Tile & Stone LLC consulted with one of the most prominent natural stone experts in the industry, Fred Hueston of Stone Forensics, to test and research possible solutions for moisture discoloration. They continue to compare notes with other industry experts, including Foster Lyons of Foster Lyons Building Science, to provide reliable, fact-based technical information regarding this ongoing problem. 

Hueston interviewed Lyons, a building science consultant who specializes in water and moisture dynamics. He offered unique insight into how water molecules interact with each other, penetrate natural stone and other porous building materials, and contribute to various processes, including the problem of moisture discoloration. This article is not a complete transcription of that interview and has been edited for clarity, flow, and brevity. You can listen to the full interview at Fred Hueston’s The Stone and Tile Radio Show Podcast.
