Hi, Charles. Welcome back to Just Answer.What type of wood is the deck made of?
It is pressure treated lumber ..I am afraid that I dont know any more other than it was decking material
Charles, PT lumber doesnt have to be treated. It already is.
I doubt that the decking is actually PT lumber though. It is very expensive. The frame of the deck might be, but not the actual deck surface.
Can you provide a digital picture of the deck? You can upload it to http://tinypic.com
Just post the last link here.
I got someone else to assist in this matter. I don't know how you could assume my deck was not constructed using pressure treated material.
Most decks are constructed with pressure treated lumber as the frame work only. Pressure treated wood is not recomended for human contact due to the chemicals in it being carcinogenic.
The deck material that people might come into contact with are either specialized decking material (Trex) or regular wood that is stained, and weatherproofed or just painted with exterior grade paint.
