STEP 5: Adhering Tiles __ If you are using tile, chances are that it's in a setting where moisture is a given__kitchen, bath, entryway and so on. Make sure you use a waterproof adhesive. You can use a premixed adhesive or a mortar, but if you choose the latter, make sure it's a thin_set variety. (Thick_bed mortars require some practice and skill at smoothing to get the tiles to sit flat, and the additional mortar isn't necessary for a watertight finish.)
Dampen a sponge with water. Scrub the area to work the baking soda into the stains like a scouring powder. Rinse the baking soda and vinegar off the tile with clean water. If water spots remain, repeat the process. When the tile is clean, dry it with a towel to prevent minerals in the rinse water from leaving new spots.
