The time it takes to complete the process of demoing, floating, sloping, and reinstalling 2x2 mosaic tiles for a 20 square foot shower floor can vary, but here's a rough breakdown:
Demo: Demolishing 20 square feet of mosaic tiles typically takes several hours, possibly up to a full day depending on the complexity of the removal and the condition of the existing tiles.
Float and Slope: Floating and sloping the floor involves applying a layer of mortar or another suitable material to create a level surface with the proper slope for drainage. This process generally takes around a day, including time for the material to set and cure.
Reinstallation: Reinstalling the 2x2 mosaic tiles can take another day or so, including time for setting the tiles, grouting, and cleaning up.
Taking all these into account, the entire process for a 20 square foot shower floor might typically take around 2-3 days to complete, assuming no unexpected issues arise. However, it's always a good idea to consult with a professional installer who can provide a more accurate estimate based on the specific details of your project.
