How to use


Substrate preparation

All surfaces must be clean and free of dust. Greased surfaces should be cleaned by acetone or MAKROFLEX CLEANER. Before use it is necessary to store the adhesive at indoor temperature (approximately +20 °C) during 12 hours.


  • Place the cartridge into the adhesive applicator.
  • The tip of the nozzle should be cut off as lant (at about 45 degrees) according to the joint width.
  • Perforate protective cartridge membrane by nail or wire.
  • Apply the adhesive on one of the joint surface by zigzag or small frequent points and wait for 5 minutes.
  • Hermetically joint the surfaces and disjoint them at once for 5-10 minutes.
  • Pressure again strongly the joint surfaces.
  • If it is necessary, use additional fixing.


Tools and stained surfaces can be cleaned with white spirit before the adhesive is cured.


Must not be used for foamed polystyrene and mirror bonding applications.
