Product Description

Keim Silan Primer is a hydrophobic impregnation (water repellent) for mineral substrates with the ability to resist the passage of some waterborne salts for use with Keim Mineral Paint Systems.

Best Uses

Keim Silan Primer penetrates into the pores and any hairline cracks of mineral building materials. After evaporation of the solvent, the active component is deposited on the walls of the pore and, once subsequently coated with a Keim Mineral paint system develops water repellent characteristics.
Keim Silan Primer does not seal the pores of the building material, ensuring that the water vapour permeability of the substrate remains virtually unchanged.

It is particularly good practice to pre-treat horizontal and inclined surfaces with KEIM Silan Primer prior to redecoration to help shed water and protect the surfaces. KEIM Silan Primer can only be applied onto bare surfaces.

  • Easy to apply
  • Non flammable (when dry)
  • Water repellent
  • Helps resist the passage of salts


All loose, flaking and unstable material must be identified and then thoroughly removed. All surfaces must be thoroughly washed down with clean cold water to remove all surface dirt and dust. When all surfaces are clean, sound, wind dry, dust free and free from all surface contaminants, application of Keim Silan Primer
may proceed.

Keim Silan Primer should be applied to bare areas as a flood coat, by brush or low pressure spray, undiluted and within a period of 2 to 6 hours. These times are critical. The first coat of Keim Mineral Paints must then be applied.

Ambient and substrate temperature above 5°C and below 30°C. Do not apply in direct sunlight or onto sun-heated surfaces , nor if it is raining or if there is an immediate likelihood of rain.
