This material looks great on countertops and fits perfectly and flawlessly on the toilet floor. However, I wouldn't recommend using it near bathtubs, on the floor next to a shower or bathtub, or in other heavy water areas like sinks. Doesn't seal. It sticks much easier if you heat it beforehand. I put it in an old microwave (this microwave doesn't fit food, it's only been used for DIY projects *works great for glue tile projects!) I deducted 1 star because the glue is blue and dries blue so areas in where the glue is pushed out (mainly at the ends) stands out from the white surface. I found a way to avoid this by removing some glue from the ends before gluing them on. I wish they could find a way to make an adhesive that turns transparent after drying.
