Place the cutting edge on the cross hatch adhesion tester on the desired surface
Press down gently onto the area, pulling the adhesion tester towards you in one fluid movement to make a series of steady, parallel cuts along the area approximately 20cm long
Place the cross hatch adhesion tester at a 90 degree angle to the first cut and repeat step 2, creating a lattice pattern onto the surface coating
Brush the area lightly along the lattice to get rid of any loose debris
Inspect area to see if the cuts have penetrated through the coating
Remove and discard 2 complete turns of the adhesive tape.
Remove an additional length of tape approximately 75mm from this length
Place this cut piece of tape in the center of the lattice, remembering to smooth it down with your finger and rubbing firmly with your nail to create a good adhesion application between the tape and coating
Within 5 minutes of applying the tape, pull it off with one smooth movement at approximately 1 second at a 60 degree angle to the surface
With tape, apply to a transparent film to maintain a permanent record
Access the coating adhesion by viewing the lattice cuts in good lighting and compare these cuts to the ISO/JIS standards table.
