How can I prevent or clean the fungi that darken the tile joints?

Use grout with antifungal action (e.g. Weber.Color Premium) to prevent or clean fungi that darken tile joints and, after drying, apply a waterproofing product (damp protection) - e.g. Weber.hidrofuge P, or any other water-based product. Maintenance should be carried out every 4 years and this product should be applied again.

Weber.Antimousse, for example, can be used to clean joints without this protection (applied with a paintbrush). Wait one hour to brush the area and then clean with plenty of water. If necessary, repeat the operation.

How to make a floor plan:

With the help of a tape measure, measure the long side and the short side of your bathroom.
Create a simple drawing and write down the measures.
Also add structures: doors, windows and sanitary items.
If you want you can also add measures for doors and windows and their distance from the wall.
If you want to remove any sanitary ware please mark with an X.
The more information you add, more accurate your bathroom will be.
