Crystal Lok

Water-based concrete penetrating sealer

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

Environmental Benefits:

  • Water based

  • Non Hazardous

  • Solvent-free, odor-free, non-toxic and non-flammable

  • 0 VOC (zero Volatile Organic Content)

Additional Features

  • Blocks penetration of acids, caustics, petroleum products, mine wastes

  • Permanent - cannot erode; does not require subsequent re-application every few years

  • Can be shipped by any method - UC 2839.19.00.00 DOT Class 55 NMFC: 033880.2 d

  • Not UV-sensitive

  • Holds concrete at pH 11+, higher than oxidation levels for concrete and imbedded steel, therefore---

  • Passivates encountered structural steel within concrete mass

  • Accepts any normal maintenance after application - acids, polishing, grinding

  • Effective as a negative-side waterproofing against a hydrostatic head of over 115 ft/35 m

  • Reduces or eliminates efflorescence and leaching in concrete

  • Improves the bonding of cementitious toppings, coatings and paints

  • Ultra-violet stable
