Two questions really. First, the fence posts I've got aren't very stable anymore. They move back and forth easily.
It looks like they were set in cement or concrete (I'm not sure what the difference it) but it's like the wood is smaller now or something and moves around inside the hole - if that makes any sense.
Can I just pour more mix down there - or do I need to dig up the whole post?
Secondly, I have some pressure treated lumber I was using on my deck it is 5/4" thick, and 6" wide. Can I use this on my fence?
