Masonry & Concrete Safety Pro-Tip
Wet cement and concrete products are highly alkaline (pH ~12 to 13) due to calcium hydroxide formation during hydration. Contact with wet mortar, render, or concrete can cause severe chemical burns to skin. Always wear moisture-proof heavy-duty nitrile gloves, safety goggles, and sturdy boots.
