will this remove water stains?

It worked very well on the small mold discoloration. I'd try it for water stains because of the completed coverage on the darker mold stains. Seems as opaque as would be needed....

Need to wait 2 days before applying second coat to undersink area. Is that a problem?

I do not know for sure; I used the stuff in an un-ventilated cupboard and applied 2 coats as 1/day. I do not recall anything thing that conditioned application other than to be sure that the previous coat was dry. Clearly there is some chemical reaction going on, but once dry one may imagine that the process is complete? Good luck.

Did this get rid of mold? For how long? Did the mold come back later?

Yes it did get rid of the mold. There are a couple of spots where the mold is returning but they seem to be areas that did not get as much paint but even those areas took about 6 months to return. I highly recommend this item in fact I am planning to order more for another room. T

I'v used many paints some more expensive, this has far more benefits then the others, yes it is expensive too as the size of tin is not that big, other paints still get mould on top and you have to wipe it down, this one also repels mould , so stopping it building up and smelling the room,

No larger quantities available.

I disliked that I could only purchase one quart. Would have preferred a 4 quart tin.

The tin was shipped with LEAKAGE.

I ordered this product and it came opened. there was a leakage and it was a loss for me. I still used it and it seem to be okay. I will monitor for a few months and see if there is any recurrence to the mould problem. Product is good.
