Rust is a metallic compound that can form on the surface of the concrete. Although it may not be aesthetically pleasing, rust typically does not damage concrete. However, if left untreated, rust can cause corrosion and pitting of the concrete surface.
There are several ways to remove rust from concrete. One popular method is to use a commercial rust removal product. These products are available at home improvement stores and work by dissolving the rust. Be sure to follow the manufacturer’s instructions carefully, as these products can be corrosive.
No matter which method you choose, be sure to rinse the concrete thoroughly afterward to remove any leftover chemicals or residue.
Ways On How To Remove Rust From Concrete
Use Of A Concrete Saw
If the rust is superficial and not too deep, you can use a concrete saw to remove it. A circular saw with a diamond blade will work best. First, mark off the area where the rust is located. Be sure to stay within the lines, as you want to cut in a straight line. Next, put on your safety gear and turn on the saw. Hold the saw against the concrete and apply pressure.
Keep the saw moving so that you don’t end up cutting into the concrete deeper than you wanted to. As you’re cutting, keep an eye on how much rust is coming off. If it’s looking like it’s starting to come off too easily or if you’re going too deep, stop cutting and try another method. Once you’ve removed all the rust, rinse the area with water and dry it off. You may need to seal the concrete with a sealant to protect it from future rusting.
Use Muriatic Acid
If the rust is more severe, you can use muriatic acid to remove it. Be very careful when using this product, as it can be dangerous. First, mark off the area where the rust is located and put on your safety gear. Pour the muriatic acid over the rust and let it sit for a few minutes.
The acid will start to eat away at the rust, so be prepared for some fumes. Use a brush to help scrub away the rust. Once all the rust is gone, rinse the area with water and dry it off. You may need to seal the concrete with a sealant to protect it from future rusting.
