There is a tremendous variety of bricks on the market. They can be either solid or with cavities. Due to the relatively low strength of masonry, the loads taken up locally cannot be particularly high. Holes drilled for anchors may run into mortar joints or cavities. Care must be taken to ensure that a layer of insulation or plaster is not used as the base material; the depth of embedment must be in the actual base material. From Ceresit chemical anchor range, CF850 is most suitable for application ina hollow brick, allthough one can also use CF920.
PRODUCT PREPARATION: Remove the cap and attach the supplied static-mixing nozzle to the cartridge and load the cartridge into the correct dispensing tool. In case of a foil tube cartridge, cut off the clip before use. For every working interruption longer than the recommended working time as well as for new cartridges, a new static-mixer shall be used.
1. Holes to be drilled perpendicular to the surface of the base material by using a hard-metal tipped hammer drill bit. Drill a hole in drill method according to material type. Drill a hole into the base material, with nominal drill hole, diameter and drill hole depth acc. to the size and embedment depth required by the selected anchor. In case of aborted drill hole, the drill hole shall be filled with mortar.
2. Blow out from the bottom of the drill hole two times. Attach the appropriate sized brush to a drilling machine or a battery screwdriver, brush the hole clean two times, and finally blow out the hole again two times.

4a. Insert the sleeve flush with the surface of the masonry. Only use sleeves that have the right length. Never cut the sleeve except the sleeve 16x130/330. For installing the sleeve 16x130/330 measure the required length of sleeve, cut the sleeve from the top and set the cap on it before pushing it through the fixing element.
4b. If the base material is covered with ETICS, insert the metal sleeve flush with the surface of the masonry. Only use sleeves that have the right length. Never cut the sleeve except the sleeve 16x130/330. For installing the sleeve 16x130/330 measure the required length of sleeve, cut the sleeve from the top and set the cap on it before pushing it through the fixing element.
5. Cut off the foil tube clip before use. Prior to dispensing into the anchor hole, squeeze out separately a minimum of six full strokes, and discard non-unirformly mixed adhesive components until the mortar shows a consistent grey colour.
6. Starting from the bottom or back fill the sleeve with adhesive. For quantity of mortar attend cartridges label or installation instructions. Observe the gel-/working times.
7. The position of the embedment depth shall be marked on the threaded rod. Push the threaded rod into the anchor hole while turning slightly to ensure positive distribution of the adhesive until the embedment depth is reached. The anchor shall be free of dirt, grease, oil or other foreign material.
8. Allow the adhesive to cure to the specified curing time prior to applying any load or torque. Do not move or load the anchor until it is fully cured. After full curing, the fixture can be installed with up to the max. torque.
