This project was quite a challenge. Steam cleaning was applied and then removed the old caulking then I color-sealed.
This was my favorite project. This floor was an office in a Catholic Church. The floor is over 100 years old and was installed one small tile at a time! Previous church leadership installed carpet on top of this beautiful marble tiled floor! All that brown stuff was carpet glue. I used a floor machine to scrub and then extracted the dirt with my truck-mounted steam machine.
This is a typical project. After years of improper cleaning the grout got dirty. I steam cleaned and then color-sealed the grout to blend in with the tile.
This is my daughter “miss mess”. The juice did not penetrate the grout. The paper towel is soaking it up!
After a steam cleaning, I applied 2 coats of silicon sealant enhancer. 4 to 6 year product life. AMAZING!
