I installed a natural bamboo floor (glued) over concrete, about 2years ago. Over this time period the floor is a different shade where the sun has been on it. Example would be the bamboo under the large dining room rug is much lighter, almost like the day I installed it, than the surrounding floor. Areas under couches and chairs too are very light.
My question is can I sand down this floor and make the coloring all uniform? Is there another idea to match it all up again?
