How To Properly Apply Muriatic Acid To Concrete With Aluminum or Metal Borders

Muriatic acid is a powerful cleaning solution that can be used to clean concrete with metal or aluminum borders, but it should be used with caution. Here's how to properly use muriatic acid to clean concrete:

1. Safety precautions: Before using muriatic acid, make sure to wear protective gear such as gloves, eye protection, and a respirator mask. Also, work in a well-ventilated area and keep the solution away from children and pets.
2. Mix the solution: Dilute the muriatic acid with water following the manufacturer's instructions. Usually, a solution of one part muriatic acid to ten parts water is recommended. Never add water to the acid; always add the acid to the water.
3. Apply the solution: Using a stiff-bristled brush, apply the solution to the concrete surface with metal or aluminum borders. Let it sit for 10-15 minutes, but do not let it dry.
4. Scrub the surface: Scrub the concrete surface with a stiff-bristled brush to remove any stains or buildup. Be careful when scrubbing around metal or aluminum borders, as the acid can damage these materials.
5. Rinse the surface: Rinse the surface thoroughly with water to remove any remaining solution. It is important to rinse the surface completely to prevent damage to the metal or aluminum borders.
6. Neutralize the surface: Neutralize the surface by rinsing it with a solution of one part baking soda to ten parts water. If the bubbles turn yellow or green, the solution is too HOT, dilute with a little more water.
7. Final rinse: Rinse the surface with water one final time to remove any remaining solution.

By following these steps, you can properly use muriatic acid to clean concrete with metal or aluminum borders. Remember to always use caution and follow the manufacturer's instructions when using muriatic acid.
