Is pine wood weather resistant and good for outdoor wood structures?
Question:
Answers:
Generally no.
White pine does not hold up to weather well at all. Yellow pine is a much more weather resistant than white pine, but still should be given some kind of coating -- good oil primer with a latex paint is best. Even with proper paint, untreated is not suitable for a structure, only siding or trim.
Also, most pressure treated lumber (commonly called salt treated, ACQ, etc) is yellow pine. Treated yellow pine lumber is good for outdoor structures. Once treated it is rot resistant, but should still have some kind of coating to protect from checking and general weathering. Deck stain, paint, etc.
actually there is different treatments for yellow pine lumber and only one of them is good for outdoor use. This is ACQ treated lumber. The green treatment for yellow pine. No untreated pine is good for outdoor use. On the other hand you will see blue colored southern yellow pine. THis is called a borate treatment of wood. This is not for outdoor use either. THis is only for indoor use. The other options are western red cedar and cypress these are both great outdoor woods.
No, it is a soft wood and easilly deteriorates in bad weather especially North Westerly USA or coastal areas. You can try to treat it with a weatherproofing agent but it is inevitably going to rot.
Try cedar with waterproofing. It smells nice and although a soft wood, will last much longer. You can also use pressure treated lumber as it is kiln dried and pressed to alleviate moisture!
Pine is actually about the worse wood you could possibly use for exterior purposes. That is assuming it will be exposed to the elements. Pressure treated wood is Pine and is the only exception. It's made for exterior and constant exposure to the elements.
You'd be much better off with pressure treated lumber, cedar or red wood.
