We have two very different colors of floor, new vs old. We liked the rich color of the old wood when we applied wood conditioner. This same color can be achieved with red oak stain on the new, so old and new blend nicely. A sample piece of each, both unvarnished, still look great and match after three days.
So to my project.... We stained the new wood red oak, like the sample, a day later I conditioned the old wood and got that rich color again. So far so good. I then varnished the old wood, over the conditioner. Everything was wonderful and colors were great!
A couple hours later, the old wood is fading in color, going back to it's dull self where as the sample still maintains the rich color with conditioner only. What happened and how can I get the beautiful color that the conditioned wood has? Was it acting like a wet floor and now it's drying? Why is the sample keeping the color?
