whatever trevor!
How am i suppost to know what it is?
It says it isnt limestone in one of the replies above does it not?
M8 this is the problem with stone. Limestone is the catagory. Travertine is a limestone but its not called "Limestone" if you understand.
Travertine and limestone are both alkali stones so you should not use acid on either it eats it. Using acid can be a very costly mistake 😉
