We built a new upstairs deck this year and reused old pressure treated and stained railing boards that were over 3 years old. The boards were a combination of colors, dark brown , medium brown and some never stained. We wanted them to be the same color, so we restained them a saddle brown color, McCloskey brand semi-transparent oil penetrating stain. I dont like the color, it is orange, and it is still tacky in over a month. What did I do wrong and how do I fix it . I want to either restain it a darker color, or paint or stain it white. The other problem is that the deck has indoor outdoor carpet and anything I use to remove the stain will get on the carpet. Do I need to remove the stain to paint it white and is this advised, or will it peel off if I dont remove the old stain?? Any help would be appreciated. Thanks
