My old deck is rotting out and has to be replaced. I have two proposals both recommending treated yellow pine...acq. I am not a fan of pine especially because of the knots in it. However, it seems that this is the most economical approach.

One proposal also uses the term wolmanized wood along with the term acq. I thought these are two different processes. Did the contractor make a mistake or do I simply not understand the process that well.

It is my understanding that treated yellow pine has a green tint to it but that it should take a stain just fine. In looking at the posts it seems that a Cabot semi transparent stain is the way to go. If so, do I simply tell the contractor that I want to purchase and apply.... Cabot semitransparent stain color x...

What are your thoughts on the use of treated yellow pine...

Thanks
