Penetrating sealer seeps into concrete pores to protect it from moisture and staining, cracking, and mold caused by water. This means you cannot remove penetrating sealers like topical sealers. The good news is that penetrating sealant doesn’t have to be removed before resealing, as most topical sealers must. Instead, you’ll want to buy a compatible penetrating sealant (often the same kind already in the concrete) and apply it. Always follow the manufacturer’s instructions.

A floating slab is a single chunk of concrete that sits directly on flat soil, while a monolithic slab is a single piece of concrete that includes built-in footings that reach several feet below where the majority of the slab sits. Monolithic slabs provide more support, so they’re suitable for home construction, whereas floating slabs get minimal support from the soil directly below and are more common under sheds and detached garages.

Ideally, your concrete should set slightly above ground at an angle sloping away from the fence post. This will add extra support and allow water to run away from the wood fence post. Keeping water out will help prevent wood rot. Additionally, you can add soil on top of the concrete for a seamless finish. 

Whether metal fence posts need concrete depends on the environment and the ground they're placed on. For thick earth and areas without significant weather or high wind, you can get by without concrete, but in areas with weak dirt and strong seasonal weather, it's a good idea to install a concrete base on each individual post. This increases the cost but not as much as replacing or reinstalling the fence would.
