Tile Damaged From New Stucco
I don't know very many responsible stucco contractors who
wouldn't cover up an area like this, just so they wouldn't have to clean
it up in the future.
Obviously this wasn't the situation and the tile was damaged from the new stucco that was applied to the building. The only problem with this, is that the tile was also new.
Home Repair Tip: Try not to use abrasive cleaners, because you might scratch the surface of the tile. I would recommend wetting this area with water and cleaning it with a soft towel.
It might take a little while, but this usually works pretty good, even though it might not remove all of the stains. If the area isn't very big and you can't clean the titles as good as you would like to have them cleaned, you can always remove the titles and replace them.
Home Building Tip: With some good planning, you can avoid situations like these. If you're building a brand-new home or remodeling an existing one, it wouldn't be a bad idea to apply the stucco and finish it, before laying any tile.
It wouldn't be a bad idea to make sure that all of your painting and exterior finish work is done, before laying the tile also. That tile should be one of the last things that a builder does when building a home. The reason for this is simple, you're trying to avoid as much traffic as possible on any flooring in the home.
The more that people working on the home, walk on your flooring, the better the chances are that it can get scratched or damaged.
