Application steps

APPLICATION INSTRUCTIONS

SUBSTRATE PREPARATION

Surfaces must be clean and dry. Use suitable methods to remove dirt, dust, oil an all other forms of contamination that could interfere with the adhesion of the primer. 

CONCRETE

Concrete must be cured for min. 28 days. Mechanically surface profiling is the method of surface preparation. Mechanically profile the surface to CSP3 as described by the International Concrete Repair Institute. Voids and pinholes must be repaired. 

STEEL

Prepare to SSPC-SP6. Surface profile 50 - 75 micron.

MIXING

  • Sikagard® P 659 is supplied in two pre-weighed components, base and reactor. 
  • No additions or omissions are required. Do not split the kit, mix full unite only.
  • Add reactor contents to the base component and mix thoroughly by using a slow speed drill fitted with a suitable mixing paddle until a uniform streak free color is achieved.

APPLICATION

Sikagard® P 659 may be applied by airless spray, brush or roller.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with suitable thinner (e.g. Xylene), immediately after use. Hardened and/or cured material can only be removed mechanically.
