When Crystal Lok is applied to concrete, it’s pulled into the capillaries and pores and within 15 minutes begins the waterproofing, damp proofing, and hardening process.

Waterproofs

• Blocks water (fresh and salty) from rains, floods, storms, waves
• Prevents freeze-thaw spalling

Seals

• Seals against de-Ice chemicals
• Prevents algae, mold, fungi infiltration & discoloration
• Prevents chemical corrosion

Damp proofs

• Allows structures to expel trapped water as vapor.

Hardens

• Improves surface abrasion by 65%
• Increases concrete density and hardness
• Prevents physical abrasion
• Stops expansion cracking from temperature fluctuations

Raises pH – (11.3-11.5 same as new concrete)

• Helps keep embedded steel fiber, mesh and rebar rust-free
• Reduces re-rusting in aged concrete

Application

• Single application liquid
• Apply to dry, damp, or wet surfaces (not into puddles or flowing water)
• Apply with any method – brush, spray
  • Penetrates up to 3/4 inch converting to new C-S-H (Calcium Silicate Hydroxide – pure cement), filling pores, capillaries, voids & hairline cracks with CS
• Can be top coated with concrete-specified coatings, mastics, adhesives
