A revolutionary and unique in the world product that is as easy to install as peel and stick! The do it yourself peel and stick tile concept of smart tiles is made of an adhesive substrate topped with a clear gel component called Gel-0™ (which gives it its 3-dimensional effect) that makes the product so easy to handle, cut and maintain you will wonder why this was not invented before. Especially designed for Kitchen and Bathroom environments (i.e.. backsplashes), they are resistant to the heat of stovetops and the humidity of bathrooms.
