APPLICATION
IMPORTANT
Sika® Rustoff-100 is not a permanent passivator. Soon after rust removal, apply a corrosion protection coating such as Sika® Rustop, Sika® FerroGard®-950 IN or Sika MonoTop®-1010 IN.
Apply Sika® Rustoff-100 by brush, cotton waste swab or spray on the effected metal surface. Leave it in contact with the surface till the reddish colour of the corroded surface has changed to nearest original black. Excess application may sometime give whitish black surface. After a minimum 24 hours remove the loose rust particles by brush.
After the removal of loose rust any reddish rusted surface still left has to be re-treated with Sika® Rustoff-100. After the surface dries up totally (within 48 hours). Clean the surface with water jet and allow it to dry. Apply a preventive coating like Sika® Rustop.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened material can only be removed mechanically.
