Sikaflex Primer

Depending on the type of surface you are using Sikaflex adhesives and sealants on, it must first be treated with a suitable Sikaflex primer or activator. In some rare cases, sanding the surface and/or removing oil, grease and dust is all that is required. The type of Sikaflex primer that should be used for a particular Sikaflex sealant or adhesive depends on several factors:
1.) The material of the surface to be bonded or sealed
2.) The surroundings or environment in which the sealant or adhesive is to be used
. - Indoor or outdoor
- Temperature and water exposure
- Environmental conditions (e.g. highly corrosive environments)
3.) Mechanical stress (bonding of small parts or large parts where more movement of joins is to be expected)
. To find the right Sikaflex Primer or Sikaflex Activator for your Sikaflex adhesive or sealant, feel free to contact our water sports experts for individual advice.
