Field of application
- Restoring, supplementing and re-profiling mineral substrates such as natural stone, brick, concrete and synthetic stone
- Reproducing ornamental building elements in a tamping procedure
- Low free alkali content
- Good flank adhesion
- Low inherent stress
- UV-resistant pigments
- Can be made hydrophobic
Clean, dust-free and capable of supporting a load.
Any necessary cleaning measures should be performed as gently as possible, e.g. by spraying with cold or hot water or steam cleaning; stubborn dirt should preferably be cleaned using the rotec soft blasting method or Remmers cleaning products (e.g. Clean FP, Clean AC basic, Clean WR).
Preserve valuable heritage ornamental elements and statues by carefully removing encrusted dirt and using the appropriate Remmers Stone Strengthener to carry out repeated intensive strengthening.
Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C
Apply a contact layer to the pre-wetted substrate using grout (dry mortar/water) in a layer thickness of approx. 2 mm.
Apply the mortar onto the contact layer wet-on-wet in layer thicknesses of 1.5 to 3 cm, 1 to 2 mm beyond what will become the final surface.
Joints in the masonry must be maintained.
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 sufficient hardening (when the grain pops), roughen the surface or scrape down to the final surface.
Rework the repaired areas (using a scraper or abrasion tool) onto the structure surrounding the defective area.
Wait at least 24 hours before applying subsequent layers.
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.
Working tools / cleaning
Mixer, trowel, smoothing trowel, sponge float, cleaning sponge, smoothing board
Clean tools with water while the material is still fresh.
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 void
Apply to a large enough trial area to determine the precise amount required.
May contain traces of pyrite (iron sulphide).
Do not use on gypsum-based substrates.
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.
Low chromate content in accordance with Directive 2003/53/EC.
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.
