QUESTIONI had my bathroom re done about 1 1/2 years ago, and about 6 months ago, I starting seeing a problem with the grout/stone pebble floor in my new shower.
The floor bed is pebbles and grout.. the floor was sealed when first done, but apparently the product sold to me didn't work? Not sure but for the past complete months, I have tried numerous products, but after the floor dries, it is white all over , on the stones it looks like a haze, but on the grout it looks more white. I have tried haze remover, stone enhancer, etc.. I was hoping to use an acid to just get it back to the original, and then re -seal, but not sure if that will hurt the grout. The walls are tiled from floor to ceiling.. Is there a product that you could recommend?
ANSWERANSWER - When there is a white haze on a shower floor it is normally either efflorescence precipitation or you have trapped moisture in the tile assembly by applying a non-breathable sealer over the floor.
Efflorescence is where minerals (similar to salts) in the concrete and stone setting bed dissolve in the moisture and as the moisture comes to the tile surface it evaporates and then precipitates the white minerals. If you put a little vinegar on the white substance and it goes away, then it is efflorescence.
More likely is that they used a sealer or resin over the pebble floor that is non-breathable. If water gets under the sealer then it will tend to turn a cloudy white color. The question is why is water getting in under the sealer? That could be a problem in itself.
If it is true they used a surface sealer then there are strippers available for removing the sealer. You can then let the floor dry out and then reseal it with a breathable sealer. If you got to our website resource section there is a list of manufacturer's of sealers and cleaners that you find a link to their website to find the appropriate product for your situation.
