Watersheild pressure treated wood

recently bought water shield pressure treated lumber from home Depot to build a woodshed I am wondering when it is okay to put a water stain and sealer on it. it has some special coating on it which I'm unsure how to tell if it is dry or not. It feels dry to the touch. I did try putting water on it which did bead up but this is to be expected with the type of water shield that is on it. Has anyone used this material?

It takes a good year to allow the PT wood to dry out, seal/paint before the water escapes and the top coat goes right with it!

I bought Thompson water shield stain/sealer. Theoretically I should be able to apply that to the wood now then.

I'd return the TWS, while it does a good job of sealing the wood from moisture it's short lived and does little to prevent the wood from turning grey.

Usually you can stain treated wood somewhere between 6 weeks and 6 months - it depends both on how wet it was from the PT process when nailed up and the climate it's exposed to. I'd recommend a toner or translucent stain over TWS. A semi-transparent stain would likely look good longer.
