LK-SEAL 16

Potassium Methyl Siliconate Solution

Hydrophobic coating on exterior surfaces:

LK-SEAL 16 is an effective and versatile water repellent solution, offering long-lasting protection for a variety of substrates like natural stones, insulation material, tiles, plasters, and painted surfaces where porosity is present.

Its ease of application, durability, and compatibility with different materials make it an ideal choice for construction and restoration projects. LK-SEAL 16 reacts with atmospheric carbon dioxide (CO2) and develops water repellent properties; the active ingredient, polymethylsilicic acid, forms on the masonry substrate.

Key Features:

  • Environmentally friendly and Solvent free , aqueous
  • Retains the substrate’s original appearance
  • Small molecule structure allows for deep substrate penetration, retains the substrate’s water repellent for longer time
  • Easy to apply
  • Penetrating water repellent action at low dosage – fast water beading effect

Application Guidelines:

  • Ensure the surface is clean, dry, and free from contaminants such as dust, dirt, oils, and loose particles.
  • Dilute 1:10 to 1:14 by water for coatings. Lower dilution may not always give better results.
  • Optimization of dilution may be required to obtain maximum performance on selected substrates. A test application is necessary on each surface to be treated to ensure compatibility, appearance and the desired water repellent result. Do not apply if rain is expected within 6 hours.
  • Allow the treated surface to cure for at least 24 hours, protecting it from rain or moisture during this period to ensure optimal water repellency.
    For this high pH material, ensure gloves and safety PPE are used.
