Anyone use topicals in bathrooms I generally do not use topicals but was looking at an Indian slate and the customer wanted a satin finish. The obvious product is Lithofin slate seal although it could be too shiny but I hate removing solvent based products. Anyone used a water based topical that will stand up to people stepping in and out of the shower and getting the floor finish very wet. I am concerned about rapid dulling as the bath panels are also slate. I'll just enhance the slate shower floor which I usually do but she don't want dull anywhere else!
