The active ingredients which is nano-size  penetrate deeply into the substrates and bond with them, form penetration protective layer on the surface. With super low surface tension, it boosts excellent water repellency and fast beading action.

Features

  • Stronger chemically bond, long lasting protection, good durability, good stability, extend the lifespan of building material obviously
  • Good penetration into porous substrates, good abrasion resistance
  • Resist water vapor, moisture and liquid water into substrate
  • One-way breathable, repair tiny crack (0.2mm-0.4mm)
  • Quickly for using and quick dry
  • Especially perform well on high density concrete
  • Chemical resistance such as acid, alkali, chloride ion, carbonation; weather, UV resistance - Excellent
  • Frost proof, anti freezing and thawing and resist high temperature(-50℃-200℃) - Excellent
  • Does not change surface appearance
  • Environmentally friendly

  • Material surface must be clean and dry.
  • Spraying, brushing, soaking or rolling are suitable for this application. Please apply under the condition of natural ventilation.
  • Spray with suitable low pressure, 10-15cm distance away.
  • Apply the material on substrate until it's thoroughly saturated, for middle or high density substrate, it needs to wipe up excess liquid with soft cloth after apply for 5-10 minutes.
  • Don't put treated material to moisture or rain place, and dry in natural air. When the surface is dry, further treatment can be folllowed.
  • After complete curing, it will achieve an outstanding hydrophobic effect.
  • Use when the temperature is between 2℃-45℃(35.6-113°F).
  • Maximum coverage per liter is 4-12 square meters, but depends on substrate density.
