Approximately how many linear feet can i expect from one bottle?

Sir, There is no easy way to calculate the lineal feet of crack coverage. other than guesstimating the the volume. It really depends on the depth and width of your crack and Length. However, proper preparation of the crack is essential. I plan on sandblasting my cracks, cleaning them out by using high pressure air or water. and then filling the void with the sealant. If you use a pressure washer you need to make sure it is allowed to dry thoroughly before putting the sealant with them. Filling the cracks on a warm day is a must. Timing helps. Good luck. Michael

Can this be cleaned up with water while using? Like using a wet sponge

Yes. Water clean up can be used.

I have a 2 tiered water fountain and the second tiered has hairline crack, can this product prevent it from breaking apart?

This product will seal the crack but it will not repair it. However our Bluestar Concrete Resurfacer may repair it since it is a concrete with added polymer for strength. Bluestar Concrete Resurfacer is sold on Amazon also.

Will this work on tile?

Yes. I’ve found it works on concrete, tile, stone and even wood. Great product.
