Solving the problem during the installation
By extending the concrete base 4 to 6 inches above the ground, leaves/dirt will not build up on the concrete.
Repairing Rusty Steel Legs
There are seven steps involved in repairing rusty tower legs in concrete. This procedure has been used successfully on one of the towers at N3RR and at a tower at W3LPL:
[Before proceeding from one step to the next, ensure that each step is fully-completed per the instructions below and per any instructions on the product(s) used.]
1. Excavate the concrete around the leg to expose "good" steel. "Good" steel is shiny. In some cases, the rust may be several inches down into the concrete requiring a concrete chisel and some hard work.
2. Sandblast the steel leg to expose the "good" steel and remove *any* remaining visible rust.
3. On the sandblasted exposed steel, paint-on Rustoleum "Rust Reformer".
4. Spray 2 coats Brite Zinc Cold Galvanizing Compound.
5. Paint 2 coats Rustoleum "Gutter Shield".
6. Paint 2 coats Rustoleum "Stops Rust" oil-base enamel paint (color choice).
7. Caulk-on GE Silicone II Concrete & Masonry Sealant.
The products mentioned are shown here, except for Rustoleum "Rust Reformer". Rustoleum Rust Reformer is sold in various sizes and may be brushed onto the rusty areas of steel. Brite Zinc is a product of Brite Products.
