What do you do if the gap between top of tub and bottom row of tile is about 1/2". Can you caulk a gap that wide and deep? I have seen sanded caulk in colors. Has anyone tried that product?


I would suggest denatured alcohol along with a very sharp chisel with no nicks in it. Drown the caulk with the alcohol and let it set for a good hour. After that gently use your chisel to slide along the base of the backsplash. Your fingernails are really good for scratching out the silicone after the alcohol has penetrating it. Once cleaned out I would ...


Once pure silicone is cured there are no cleaners or solvents, that I'm aware of (maybe an acid), to remove or dissolve it. I've had very good success removing dried silicone that had not been applied carefully by "pushing" it off the surface. With your thumb or pointer finger apply pressure on the wayward silicone smear pushing back and forth. If the bead ...


While caulk is fairly elastic, it handles better under compression than tension. By filling the tub all the way, you expand the gap quite a bit. Once the caulk is applied and the tub drained, the caulk compresses. During normal use, the caulk will likely never be in tension. As you'd have to add more weight than a tub full of water, before the caulk had to ...


Depends on the tub, to some extent, and how (or if) it was bedded when installed. Acrylic, fiberglass and thin steel tubs do noticeably deform with a load, especially if not bedded (I'm a fan of the good old plaster bed under the tub.) Most cast-iron tubs don't deform to any noticeable extent.


the water pulls the tub to the position it is in when you take a bath the sides slitly deflect and it pulls down from the surround so filling is the best practice to fill the voids and have a longer lasting seal that wont leak
