This is a follow up for this question Deck footing 2" above the ground -does that apply to a patio? What is the reason behind the 2" restriction?
I decided to have my concrete footing under the patio and covered with gravel (and possibly bricks on top of it. These are 10" sonotubes on top of which I installed these: enter image description here

The concrete footing and part of the pipe side of the support will be under the patio bricks. I would like to seal the top side of the concrete pier with some sealant (epoxy spray?) . Is that a good idea? I will also try to complete cover the screws and the foot of the support in one more layer of epoxy to make sure they will have a long life

The other option that I have would be to use concrete sealant I still have one tube of this: enter image description here

  • Why would you like to seal it? If it was wood direct on concrete I would get it but you have a barrier between the wood and concrete already. – The Evil Greebo Jul 12 '17 at 15:42
  • I just don't know if I have to , that is why I am asking. Besides that the concrete will sit under patio and it will be constantly wet/humid. I don't know if that is fine or not. The adjustable support might not be OK to sit in humidity all the time. That is why I am split between covering the footing with gravel vs covering it with bricks. One is OK in summer but bad in winter and viceversa – MiniMe Jul 12 '17 at 15:46
  • Concrete doesn't care about moisture unless it's reinforced concrete. The support you added looks to be well painted and should stand up to the elements for 20 years or so. – The Evil Greebo Jul 12 '17 at 15:50
  • I hope so, I have fence supports (spikes) that I put in the ground, made the same way, coated with that epoxy thing – MiniMe Jul 12 '17 at 16:48
