Choose The Best Water Proofer
There are several different types of waterproofers available. There are different waterproofing materials for each material. You can either go for waterproofing paint. Waterproofing with paint will help you coat the metal properly and avoid any left behind spaces. To apply the pint you can use a roller if the surface is larger like that of decorative metal wall panels.
Seal It In
Once you are done with the waterproofer you will have to seal it with a sealant. Do not go for colored sealants but chose a clear waterproof sealer that is comprised of latex. This is the final layer of protection that your outdoor wrought iron decor might need.
For the final step, you must give your waterproofing job a check. You can do that by keeping the spray bottle at a 30-degree angle and spray water. Let the water sit there for a couple of hours and then check if the decorative wrought iron still has any moisture on it or not.
If you cannot go with waterproofing just yet, you can use these tips for rust:
Waterproofing electric patio heaters can be quite difficult which is why it is a great idea to clean them with a lint-free cloth.
You can also use mineral spirits to clean your decorative wrought iron. If the iron design is intricate, you can also use a brush to get to the extreme corners. And then wipe with a cloth of mineral spirits.
