Injectaphos Phosphoric Acid Surface Prep – Professional Concrete Crack Repair Enhancer

Available in 1L or 20L format

Unlock superior adhesion and long-lasting crack repairs with our Phosphoric Acid Surface Prep, engineered specifically for concrete restoration professionals. Designed to optimize the bonding conditions before injecting epoxy or polyurethane, this solution ensures every repair is clean, strong, and built to last.

Why Use It?

• Deep Cleaning Power
  Removes dust, laitance, light contaminants, and mineral buildup for a perfectly clean substrate.
• Light Etching for Superior Bonding
  Gently micro-etches concrete, increasing surface roughness and improving mechanical grip for injection resins.
• pH Neutralization
  Reduces surface alkalinity for better chemical bonding and improved product performance.
• Safe, Controlled Reaction
  Less aggressive than hydrochloric or sulfuric acid—no significant weakening of the concrete, fewer fumes, and safer handling.
• Efflorescence Removal
  Breaks down calcium deposits and efflorescence inside cracks, allowing the repair resin to penetrate directly into sound concrete.

Ideal For:

• Epoxy crack injection prep
• Polyurethane injection prep
• Surface cleaning prior to sealing or coating
• Removing light deposits or laitance in tight cracks
