Can you put 4×4 in concrete?
No, it’s impossible. No matter how strong a mix or how much steel you put in it, it will crack somewhere. It has to. So let’s apply this to your pour, unsuspecting post, pole, 4×4, or 6×6 that you are using.
Why deck posts should not be set in concrete?
A deck post should always be placed on top of footing, not inside concrete because it can break. Concrete tends to absorb moisture and wood expands when it gets wet, so these two factors combined will result in the wood breaking the concrete.
How do you attach something to concrete without drilling?
A simple fix might include an adhesive or adhesive-baked hook, while there are other fasteners like hard wall hooks and masonry nails. Powder-actuated fasteners and concrete nail guns are useful for supporting frames and providing a much greater hold.

Can pressure treated posts be set in concrete?
Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure–treated posts, the rot will be slow. Concrete should be poured around the post – no concrete under the post.
Is it OK to set deck posts in concrete?
There are several ways to set deck posts; we recommend attaching the posts to concrete footers above the ground. This helps to prevent wooden posts from rotting. Set footers a minimum of 6” below the frost line for your area to prevent movement during freezing temperatures.
Should you use 4×4 or 6×6 deck posts?
4×4 post will be fine. I have built many decks for new homes with them. 6×6 is more sturdy of course and will not twist as easy, but for structure purposes, 4×4 will be fine. I would just not go more then 10′ apart with them.
Can you pour concrete around existing deck posts?
1 Answer. Support either side of each post, cut it off, insert a steel stub base or pour a new concrete base to a height slightly above the planned slab, pour the new slab. Or skip pouring a slab and just put in a base for pavers and build the patio from pavers.
