Butt adhesive bonding of natural stone

Butt adhesive bonding of natural stone

A butt-joint bonding of natural stone has to be able to resist strong forces. We ensure a secure connection by bonding with 2K-Mix Fast, a two-component adhesive with a very high adhesion and tensile strength (2500 n/cm²). As always, good adhesion to the substrate is the key to perfect bonding.

Step 1: Preparation

  • Smooth surfaces must be roughened with sandpaper

  • Clean and degrease the surfaces to be bonded with Multiclean. Allow to work in for a few seconds and wipe off with the cleaning cloth.

Step 2: Bonding

  • Fit the cartridge of 2K-Mix Fast onto the Tec Gun. Remove the cap.

  • Screw the mixer tip onto the cartridge. Eject around 10 cm and dispose of it.

  • Apply an appropriate quantity of 2K-Mix Fast to the butt edge.

  • Bring the two surfaces to be bonded together and apply pressure. Verify their correct positioning. It is unnecessary to keep the connection under pressure.

Step 3: Finishing

  • Remove any spilled 2K-Mix Fast immediately with Powerwipes tissues. 

  • The open working time (at 20°C) is:

    • 10 minuten for 2K-Mix Fast (complete curing after 120 min.)

    • 4 minuten for 2K-Mix Superfast (complete curing after 60 min.).

  • After curing, 2K-Mix Fast is perfectly workable: tapping, drilling, milling, cutting with a saw, etc.
