Braid,
There are several thing I would do to this floor :
1 . first strip the floor to remove any finishes that have been applied ( if there is an acrylic on it it will strip fairly easy , if it’s an epoxy or urethane it will be much harder and will require aggressive stripper)
When a floor has a coating on it I recommend a single edge razor blade to check the finish, if when scraping the floor the finish kinda of rolls off the surface it usually an acrylic finish, if it fake off it will fall into the epoxy or
urethane finishes and will be much harder to remove.
The single edge razor is your best friend when checking topical coatings.
2. once the floor is stripped and cleaned I would then go over the floor with a honing powder, depending upon the finish your customer is looking for I would use either a 250 grit or 400 grit powder, this will expose new stone and should eliminate the white water damage you are now seeing.
If the moisture problem is not corrected it will occur again, if a topical sealer is used you could compound the problem down the road.
I recently used the Stone Care Central Color Enhancer and was please with the result.
The product I prefer overall is the Stone Loc from Richard James chemical . this will do everything you are looking for once the floor is properly cleaned and prepared. This seal will stop the shedding, it will enhance the color and will allow the stone to breath, this is one of the only coating that I know will allow the stone to breath.
When applying this you must follow the manufactures instructions to the letter. I have used a product like this made by the same inventor on over 50,000 = sq ft in my past , and only had 1 small failure , not do to the product it was due to the technician not following the instructions.

If you can remove all the loose material (pressure extractor) and use a consolidant like ProSoco 40SK (which is not for floors) Dry Treat has a similar product (ethyl silicate) which you can use on floors. This will re bind the minerals. I have used it on really bad slate and it works fine. Then you can tell them you have done all you can.

there is not a lot you can do..just be sure you tell the customer that this is a problem and the moisture source must be found. Chances are the stone will need to be replaced.

Hi,
We have been asked to strip, clean and seal an old residential interior slate floor. We have done this kind of thing before and it appears somewhat straight forward assuming we can test to figure out what gets the gook off the best. Problem is that there is water damage around the edges that has created delamination on some of the stones. How do you all deal with this kind of issue? I have warned the owners that this problem may not go away if there is constant water migration underneath the stone. Hard to say if this is recurring thing. it looks like the wood floor in the next room are warped from a flood of some kind, but at least part of the floor is adjacent to an exterior wall. It is sort of a sun room. I posted some pix.
Thanks for any advice.
Baird
