Treated and Untreated Wood
My contractor is building a porch using treated and untreated wood. The porch is treated and the steps and rails aren't. He plans to paint all of them the same. Is this a problem?
I don't see any problem structurely, decks and rails are often done with a mix of wood, but when the deck is finished the stain or paint may not take the same on the different materials. Even this should blend after it has had time to season.....Mark Hammond
The only problem that will likely arise in 5-7 years is a problem with wood rot. If the wood has not been treated you will eventually have problems unless you caulk every year and paint it at least every 3-5 years. Using a product like Woodlife before it is assembled can reduce the rot problem. It is very important to use this on all cut ends before assembly. Dipping the ends into the Woodlife and soaking for a minute or 2 will greatly increase the life of the wood. For more information about this product go to: http://www.wolman.com/msdsptds.asp
I am not a salesman for this product but I have used it on many projects with good results.
