Looks great, high quality

We got a 4-ft seal of our school for the foyer in the administration building. It looks really good on the marble floor. It appears to be high quality. It has some texture to it so I am not worried about it being a slip hazard (the floor itself is quite slippery when wet). It is pretty sticky, I am not worried about it coming up. It was a little hard to apply it to the floor flat and without bubbles. We followed the instructions, but it wasn't as easy as it sounded. It's been on the floor now for several days, and each day we have noticed more air bubbles. I've been able to remove some of them, but not all of them. They're not blatantly obvious, but I can't help but see them :)
