Composite morter for 4,80 and up

Product Sheet

Description / Price

Two-component composite mortar (injection mortar, assembly mortar) with mixing tube. For each first cartridge you will receive an additional mixing pipette (MR 00200) free of charge; additional pipettes can be ordered. Cartridge content: 300 ml, polyester resin base, styrene-free and odorless, with separate strands of material in the cartridge. Not useable below 5 degrees (0 degrees F), winter mortar 280 ml to minus 10 degrees C. See online store. Shelf-life: about 3 - 11 months after delivery. Expiration date of the current batch VM 00300: 06/2018). Composite mortar in kits may have a different MHD. With MHD expiration and a single purchase: special price of 2.80 Euro. >>> Price



For expansion free anchorage or bonding. Also for the attaching of wall brackets which are subjected to axial loads. Application of composite mortar is best with professional applicator gun, also with conventional 'silicone injections' (high force required). Use winter mortar in winter. Please refer as needed to our general information on anchor technology.


How much should I use? 

The amount of mortar depends on the thread thickness, the depth of the drillhole, and the size of the annular gap between the threaded shaft and borehole diameter. The following information serves as a rough guide:


Example 1: bonding of threaded shanks (6 mm. e.g. WH 06061) in solid masonry, hole 8 mm (annular gap 1 mm), shaft length (anchoring depth) 6 cm, hole depth about 7 cm. Under these conditions, a 300-ml cartridge is sufficient for about 30 - 50 wall brackets.

Example 2: bonding of threaded shanks 10 mm (e.g. WH 10151 or WM 10101) in solid masonry, drill hole 12 mm (annular gap 1 mm), shaft length (anchoring depth) 10 cm, hole depth 11 cm. Under these conditions, a 300-ml cartridge is sufficient for about 15 - 25 wall brackets.

Example 3: Bonding of threaded shanks 10 mm (e.g.  WH 10151 or WM 10101) in hollow masonry, drill hole 16 mm, with sieve sleeve, shaft length (anchoring depth) about 8 cm, hole depth about 10 cm. Under these conditions, a 300-ml cartridge is sufficient for about 7-10 wall brackets.

Example 4: bonding of threaded shanks 12 mm (e.g. WM 12191) in solid masonry, drill hole 16 mm (annular gap 1-2 mm), shaft length (anchoring depth) 12 cm, hole depth 13 cm. Under these conditions, a 300-ml cartridge is sufficient for about 6 - 8 wall brackets.

Example 5: bonding of threaded shanks 12 mm (e.g. WM 12191, WM 12XX8) in hollow masonry, drill hole 16 mm, with sieve sleeves extra long, shaft length (anchoring depth) 12 cm, hole depth 14 cm. Under these conditions, a 300-ml cartridge is sufficient for about 4 - 6 wall brackets.

Example 6: Bonding of special mount WM 12XX2 in hollow masonry behind thermal insulation 12 cm thick with formation of a support corn in the insulation, rear drill hole 16 mm, with extra long sieve sleeve, shaft length (anchoring depth) 12 cm, hole depth 14 cm. Under these conditions, a 300-ml cartridge is sufficient for about 1 to 1.5 wall brackets.


The amount of mounting mortar needed can - as in Example 2 - be significantly higher if previously undetected cavities in the masonry are found that need to be filled as well. It may also happen that a hollow wall was not recognized from the outside as such, and therefore much more mortar is needed. Excess mortar can end up being used by inaccurate dosing-- that is, when one is 'trigger' happy with the applicator gun and too much injection mortar must be wiped away as waste.



Please refer to the instructions we provide on drilling, the product sheet for the element to be bonded, and to the section on sieve/mesh sleeves. Mesh sleeves must be inserted first. Please also observe the information provided on the injection mortar cartridge-- note especially the opening times and the curing times (this at 5 degrees celsius for 120 minutes up to 35 degrees celsius 20 minutes). Application is only possible at temperatures above 0 degrees celsius; please inquire if you require frost-resistant composite mortar (see above). If walls are wet or drill holes damp, the setting time increases by about 30%. The cartridges should be at room temperature when used. In the case of overheated cartridges due to sunlight or storage in warm rooms (unshaded vehicle), setting times can be drastically reduced and use increased, especially in hollow masonry because of a more a fluid consistency. If necessary, cool the cartridge down.


Unscrew the protective cap of the cartridge-- if necessary, cut off the foil behind the metal clip or pull out the tab, screw the mixing tube on and then insert it into a commercial mortar gun. After setting up the mixing tube, squeeze out the first 10-25 cm of mortar and do not use it. The composite mortar emerging at the front must have a dark grey colour--this indicates good mixing of the components. Squeeze the first 10-25 cm mortar strand after placement of the mixing tube and do not use. 


Insert the mixing tube nozzle into the end of the borehole, then start squeezing while slowly pulling the mixing tube out of the hole. After filling each hole, activate the 'breaker' tab towards the back of the ejection gun to prevent more composite mortar from swelling out of the cartridge. Ideally, each hole is only filled so far that the front 3 -  5 cm remain empty and fill only upon insertion of the respective shank, as the mortar then swells out. Wipe off any excessive mortar adhering to the outside of the mixing tube, as it hardens and makes reinsertion in other holes more difficult. Do not only insert the threaded shafts to be bonded, but also insert them into the mortar mass by turning them in like a screw.


Work in such a way that a broken cartridge is emptied quickly and completely. A half-full cartridge that has been screwed back on can be clogged and thus unusable after an interruption of approx. 1 hour (say, your lunch break).


If you use multiple cartridges in a single operation, the first mixing tube can be used for the next cartridge, but again, about 10-25 cm of mortar must be squeezed out to ensure that the composite mortar is mixed thoroughly.


Further Use

Shelf life at date of delivery- about 3 - 11 months (see above). Experience shows that the cartridges are usually still usable a long time after opening. If a not-completely-depleted cartridge is needed again, then unscrew the mixing tube, throw it away, screw on cap. For later re-use, use additional mixing tube MR 00200; prior to its placing, remove any dirt or lumps under the cap.



The poor thermal conductivity of composite mortar reduces thermal bridging when installing brackets in facades with external insulation; the annular gap should then be 2 mm (differential shaft to hole 4 mm).



Made in Europe, exact location depends on the product range of changing manufacturers; currently in Italy.
