To provide for a sealing of the surface of the concrete base you could consider using an epoxy based paint material similar to what is used for garage floors. Since it will be outside you will need to ensure that the finish you use has resistance to degradation from UV rays.
Will a steel post rust in concrete?
Probably the most common area where steel posts corrode to the point of failure is at ground level. This corrosion occurs due to incorrect concrete application. Concrete must be domed around posts to eliminate water pooling.
How do you attach a metal pole to concrete?

Quote from Youtube video: Clean that hole out a little bit though and then we'll be ready to set our posts grab. My coffee here and walk up to the barn. See what Chris is doing went to Home Depot. Got. Some more materials.
How do you protect galvanized steel?
MAINTENANCE AND CLEANING GALVANIZED STEEL
- Avoid long periods of exposure of your galvanized steel product to environments where the pH is below 6 and above 12. …
- Avoid direct contact of your galvanized steel product with dissimilar metals, such as brass and copper, particularly in corrosive environments.
What can you put between concrete and metal?
That means Loctite PL Concrete Non-Sag Polyurethane Sealant is the right choice: it’s a concrete caulk that is suitable for repairing cracks in vertical and horizontal surfaces and bonds to concrete, brick, stucco, metal, wood, vinyl, fiberglass, and other substrates.
Will concrete corrode galvanized steel?
After the initial curing stages of the concrete, the reactions between the concrete and the galvanized steel cease. Once the concrete has hardened, the only access that corrosive compounds have to the galvanized rebar is through the pores of the concrete matrix.
What prevents steel corrosion on concrete?
Additional measures to mitigate corrosion of steel reinforcement in concrete include the use of corrosion inhibiting admixtures, coating of reinforcement (for example, with an epoxy resin), and use of sealers and membranes on the concrete surface. Sealers and membranes, if used, have to be periodically reapplied.
How deep should a 10 ft pole be?
The general rule of thumb when setting a post is that the depth of the post’s hole needs to be one-third to one-half of the actual above-ground height of the post. So, a six-foot-high finished post ideally needs to be buried three feet into the ground.
Can you put dry concrete in a post hole?
Quote from the video:
Quote from Youtube video: Because there is no mixing you simply pour it into the hole. Dry. Then add water when digging your post hole it is important that the diameter of the hole be three times the width of the post.
How do you attach a concrete pole to the ground?

What sealer sticks to concrete?
DAP Silicone Plus Premium Silicone Rubber Concrete and Masonry Sealant is a one-component neutral cure material that cures to a tough rubbery solid upon exposure to moisture in the air. It provides a long lasting, flexible, watertight seal and offers excellent adhesion for concrete and masonry applications.
How do you seal a sill plate to concrete?
Air seal between the sill plate and the sub-floor with caulk, foam, or an equivalent material. Install a foam gasket beneath sill plates that are sitting on concrete or masonry and adjacent to conditioned space to both air seal and serve as a capillary break between the concrete and the sill plate.
Does galvanized steel react with cement?
During curing, the galvanized surface of steel reinforcement reacts with the alkaline cement paste to form stable, insoluble zinc salts accompanied by hydrogen evolution.
How long will galvanized pipe last in concrete?
Galvanized pipes have an average lifespan that ranges between 40 and 50 years. However, pipes that are well-built, well-installed, and well-maintained can easily exceed the typical lifespan. Read below to learn more about the life span of galvanized pipes.

How long does steel last in concrete?
This approach represents an improvement step for the durability design of reinforced concrete structures, it is suitable for the design of ordinary structures designed with traditional materials (Portland cement, carbon steel rebar) and with an expected service life of 50 years.
Does stainless steel rust in concrete?
“The advantage of stainless steel is the extremely slow rate at which it corrodes in a concrete/chloride environment. Minimal corrosion damage is anticipated during a service life of 75 years.
Will galvanized fence post rust?
The short answer is, yes, and also no. Galvanization is a zinc coating applied over the top of steel. It prevents rust and corrosion far longer than paint will, often for 50 years or more, but eventually that brown rot will set in.
Can you cement over metal?
Concrete itself will not damage steel (steel reinforcing bar is used regularly embedded within concrete) but a high degree of moisture within the concrete (ie from rain) could. Concrete is a “reservoir” material and actually can absorb & hold liquid water, even once cured & hardened.
Can concrete touch metal?
Generally, no damage will be observed in concrete be. cause of the softness of the lead which will absorb the expansive pressures caused by the formation of corrosion products. Cadmium coatings will satisfactorily protect steel em. bedded in concrete, even in the presence of moisture and normal chloride concentrations.
What metal do you put in concrete?
Other metals: Chromium and nickel alloys generally have good resistance to corrosion in concrete, as do silver and tin.
Why do you put steel in concrete?
To increase its overall strength, steel rods, wires, mesh or cables can be embedded in concrete before it sets. This reinforcement, often known as rebar, resists tensile forces.
