Below is a summary of how to apply Controll Innerseal.   For a more detailed explanation of how to apply Controll Innerseal, view the video below or read detailed instructions in PDF format.


Preparation and direction of use:

  • The surface must be free of dust, old paint or other incrustation that may obstruct penetration. Defect concrete/larger cracks must be professionally prepared in advance. Adjacent polished surfaces (e.g. glass, aluminium, tiles, and varnished surfaces) should be covered. Stir or shake the product.
  • Application: If the concrete surface is very dry or the temperature is above 20° C, moisten the surfaces slightly with water, avoiding pools and flow out.
  • Apply Controll® Innerseal with roll, brush or low-pressure sprayer (recommended).
  • Apply enough to visually confirm solid wetting of the surface, but avoid pools and flow out.
  • Cover range is 3-6 m2 at two applications, depending on the surface suction characteristics.
  • If the surface attracts abnormal amount of humidity, an additional coat may be necessary.
  • To increase and speed up the sealing process, flush with water after 12 to 24 hours.
  • To wash away possible secretion and consolidate maximum penetration, flush with water again after 48 hours.
  • Further secretion may appear later; however, this is not damaging and can be flushed away if required. Do not apply Controll® Innerseal if temperature is below 5°C or above 40°C.
  • Cleaning: Tool: Water
  • Skin: Water and regular soap
  • Make sure of good ventilation and respiratory protection in sealed areas, due to mist that may irritate airways.
