We recently installed a mercier prefinished hardwood flooring called whisper on white oak in our master bedroom and love the color. We are having the floors in the rest of the house which are already hardwood refinished and would love to stain them the same color. We know it won’t be exact bit since the floors are not right next to each other we are ok with it. We are told mercier does not sell their stain separately. Are there third part companies that sell them. Our installer who is great with matching says the unique color will be hard to match and he’s been trying. Any thoughts would be helpful. Thanks.
