Downloads & documents
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- First-time jointing and joint repair
- Brick and natural stone masonry
- Mortar joints from 5 to 30 mm
- Good flank adhesion
- Can be made hydrophobic
- Special colours (UV-resistant pigments) available
- Can be made doubly hydrophobic
Clean, dust-free and capable of supporting a load.
Joint depth min. 2 cm or double the joint width.
Sanded joint sides can lead to lateral detachment.
Apply the jointing in two layers if possible, press in the jointing mortar and level flush but do not "iron".
Only mix as much mortar as can be used within approx. 2 hours.
Pre-wet the open, cleaned joint.
Application of thin layers at the edges of defective areas can be facilitated by adding Remmers Haftfest to the mixing water (mixing ratio 1:10). In this case, hardening will be somewhat delayed but the bonding strength will be increased.
After application, work with a profiling tool (e.g. tubing).
Wait at least 24 hours before applying subsequent layers.
Can be applied by dry spraying:
- Solid mortar bulk density approx. 2.2 kg/dm³
- Cylinder compressive strength approx. 34 N/mm²
Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.
The type and duration of the reworking and surface treatment will influence the colour.
Slight deviations in colour between different batches are possible.
Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.
The flank adhesion can be increased by adding ZM HF [basic] to the mixing water (ratio 1:10).
Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
Working tools / cleaning
Mixing tool, smoothing trowel, jointing iron, profiling tool (e.g. tubing)
Clean tools and equipment with water before the mortar sets.
Storage / shelf life
If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.
Approx. 1.6 kg/l joint space
Apply to a large enough trial area to determine the precise amount required.
May contain traces of pyrite (iron sulphide).
Low chromate content in accordance with Directive 2003/53/EC.
The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.
The mixing water must be of drinking water quality.
Special colour according to colour number (MF no., colour swatches, NCS etc.) or submitted sample (in the case of changing or alternating colours, clearly mark the desired colour).
The colour that is obtained after drying and hardening depends on the ambient conditions and the processing method. For instance, a freshly smoothed surface will be lighter than one that is smoothed later or roughened. Different grain sizes of the same product may lead to slight differences in colour. Substrates soaked from the back may cause discolouration.
Always set up a trial area/trial areas first.
Alkaline binders may cause a dissolution process on non-ferrous metals.
Deviations from applicable regulations must be agreed separately.
The relevant test certificates must be observed when planning and carrying out work.
Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
