The mixture of the compound and hardener is done in a specially designed mixing nozzle. Properly mixed chemical anchor should have a light grey colour.
The drill hole must always be brushed out and blown clean before applying the chemical anchor. Brushing and blowing out the drill hole must be repeated at least twice. During installation in solid or porous materials the drill diameter must be 2 mm larger than the fitting to be anchored. See Technical data.
When in hollow block material a Perfo-sleeve must be used, either cut in 1-metre lengths or a Pre-cut Perfo-sleeve. Perfo-sleeves are available in three sizes, suitable for M8-M16 bolts, see accessories Chemical Anchor. When using the Perfo-sleeve the entire sleeve is filled with compound. Now press and turn the bolt and allow it to cure. For installation refer to the safety data sheet and the installation instructions.
For installation upwards, for example in ceilings this is carried out in the same manner as described above except for sizes over M30 and very long threaded rods/rebar
