The only changes you may see will be realated to the cleanliness of your surface. An ancillary beneift of our slip proofing process is an extreme cleaning of the surface. In order for the application to be effective, the floor will be cleaned to a ‘nearly new’ state. These changes are often seen more with grout that used to be gray and over the years has turned black. Our process will lighten the grout but only because of the cleaning. Although our primary business is reducing slip and fall accidents, we are often hired for an ‘extreme clean.’ This is often the case for concrete, restaurant kitchens, high traffic lobby’s, or any other surface that needs to be cleaned to a ‘nearly new’ state. One of our commercial property owners said “This is worth it just to have it this clean!’ The surface will be treated with the same process as the slip proofing.
