We just finished a job in a San Anselmo residence, where we installed a pre-finished Legno Bastone Pinot Grigio on the upper level of the house. The lower level had existing hardwood floors, which we refinished and stained to match the upper level of the house.
The worst enemy for a hardwood floor is dirt. Most dirt comes in from the outside but is also accumulated from our pets, dead skin cells, food particles, oils from cooking etc. We then scatter the dirt around with our shoes and socks and little scratches will soon be seen. Heavy traffic, pets, little children
