I used this product in my bathtub over a year ago to eliminate the slippery surface. It has done an incredible job, Not only is the bathtub not in the least slippery, I have not had to scrub any bathtub ring since putting Traction Up – Floors on it. Dirt does not stick to it. I also put this product on a very slipper hallway in an entrance and the same story. No more concerns on slipping. Great stuff is all I can say!
