Forum Title: Stair treads installation and humidity
Keep in mind this is the Oregon coast, not New Mexico or Arizona. We don't get hot, we don't ever have 25% humidity. Here's a data-logger graph of the place these oak stair treads are stored, and of the place they will be installed. His shop is heated, the home is always kept on the cool side. The treads are 1 inch by 11 1/2 inches, by 40. Stairs will be 35 inches wide. I moved the logger upstairs in the heated garage (where treads are stored on stickers), on Thursday at noon, then on Friday and for the rest of the week, it was inside the home in the living space in the area by the stairs. (pay no attention to the Noon Wednesday shop floor box where I started the logger) The finish will probably be a waterborn poly like Benjamin Moore's Stays Clear. I'm curious what the difference in temp and humidity will do to something the size of a stair tread................... especially if I seal all sides of the tread before installing them. They never keep the house very warm, and in the summer I suppose it will be a little bit warmer. The home is shaded a lot and we live near the coast, so early morning temps are rarely above 65. Daytime temps can reach mid 70's later in the summer. With the house being two stories tall and pretty shaded, not a lot of warming will occur from the daytime temperatures. Anyway, here's my graph................ what's your take on sealing all sides of the treads and installing them in this place? Does it really need a lot of acclimation? The poly will certainly dry a lot better if the treads are coated in the garage.

I don't know about the wood but those are ideal temps for me. Looks to be pretty consistent to me. Just thinking, would you really want to seal all sides and edges. To me if you did that the wood wouldn't expand and contract with the rest of the house. Daris

Walls have MDF skirt boards and the walls are wavy and move a little when you push on them.......... maybe just the skirt boards move. Not sure. Sealing them in my own mind, would stabilize them and keep humidity from getting into the bottom side.
