if the stone was flooded so was the substrate. The problem is you can only clean and sanitize the surface. If any organic matter got under the installation it will be prone to mold and mildew. This is especially true with water from the outside which will contain an organic source for the mold and mildew to thrive. You can clean it but I would warn them that it could be a problem. 

This also holds true for iron oxidation. I have seen limestone that has flooded and it sometimes take months for it to show. For this reason I again would warn them about possible problems later on down the road.

Fred,

I value the feedback from my associates and this is the first time that I've worked on Limestone. This Limestone has has many, many not holes, but flaws, Some 2 1/2" x 2." He only want it to be brushed clean and sealed. He is drying it with blowers and he told me he was using a moisture meter, however, I will follow up on that.

I'm embarrassed to admit to this, but, how do I sanitize this floor. and does it need to sit up after that? He did have it moppped.

Thank you for your time.

You can use a moisture meter to do this.
Once it’s dry you can cut the floor with resin diamonds or diamond impregnated pads. You can establish a nice honed finish.
You can use a cleaning or sanitizing
Product or products in your tank as you hone.
Is someone drying and sanitizing the floor?

Customer called me to price cleaning and sealing his limestone. The river overflowed with waves to the top of the 2nd floor door. he doesn't want it shiny, just sealed. So I have a sample piece to do for him.

The limestone is still drying out. My question is "Should I expect to clean each section twice since the water stayed on the limestone for 2-3 days." And, probably some of the silt or dirty water from the water has gotten into the pores of the limestone. What is the long term effect of that?

Thank you for your time.
