How does the pH level of cleaning solutions affect concrete coatings?

The pH level of cleaning solutions plays a critical role in the longevity and appearance of concrete coatings. Concrete coatings, such as epoxy or acrylic sealers, are designed to protect surfaces from stains, moisture, and wear. However, using cleaning solutions with improper pH levels can degrade these coatings over time.

High pH (Alkaline) Cleaners:

Highly alkaline cleaners (pH 10+) are effective for removing grease, oil, and heavy dirt. However, prolonged use can break down the chemical bonds in coatings, leading to discoloration, peeling, or reduced adhesion.

Low pH (Acidic) Cleaners:

Acidic cleaners (pH 3 or below) are useful for dissolving mineral deposits and rust. Yet, they can etch the coating surface, making it porous and vulnerable to further damage.

Neutral pH (7) Cleaners:

For routine maintenance, neutral pH cleaners are safest, as they clean without harming the coating. Always check the manufacturer’s recommendations before selecting a cleaner.

By understanding pH levels, you can choose the right cleaning solution to preserve your concrete coatings effectively.
