1. Preparing
Clean joints to a depth of at least 30mm (2/3 stone height if subjected to traffic). Clean the surface to be grouted (minimum joint width: 5mm). Adjacent areas that are not to be grouted should be taped off.
2. Pre-wetting
Pre-wet the surface sufficiently. Generally, only use clean and cold tap water.
3. Mixing
Place the mineral filler in a suitable mixing bucket and slowly and completely add the separately mixed epoxy resin in the middle of the mass. Start the stirring process with approx. 2 - 4 min mixing time. Depending on the desired consistency, as the last step, add a maximum of the same amount of water (to the epoxy resin) and stir to a homogeneous mass, e.g. for 1.0 kg epoxy resin add max. 1.0 L water.
4. Processing
Pour the entire amount of the ready-mixed paving joint mortar onto the surface and distribute it carefully with a rubber pusher and work the mass intensively into the joints. Then sweep the surface with a moistened coconut broom / hair broom and remove any mortar residues. Meanwhile, frequently moisten / clean the broom with water. Then spray the plaster surface thoroughly with a fine jet of water and sweep again with a wet coconut / hair broom. Moisture protection is not necessary in drizzle. In case of continuous or heavy rain, the freshly grouted surface must be protected against rain for 7 - 9 h (depending on temperature). The moisture protection must not be placed directly on the surface to allow air to circulate.
Frequently asked questions
After a while the system changed its look. What is the reason?
During the initial period, a wafer-thin film of synthetic resin remains on the stone surface, which intensifies the colour of the stone and protects it from dirt. This film or optical change disappears with free weathering of the surface and through abrasion over time. In case of doubt, please create a sample surface before grouting. We advise against the use of white mineral fillers as these tend to yellowing under UV radiation.
How can I influence the water permeability?
The water permeability can be influenced by the choice of the quartz sand grain size. The coarser and more even the distribution, the more permeable the paving joint. For example, the water permeability is higher with a grain size of 0.4 - 1.3 mm than with a grain size of 0.05 - 0.8 mm.
Where can I find the safety instructions?
The safety instructions can be found on the respective containers and the safety data sheets. Do not leave the product in the reach of the children. Avoid breathing vapours and contact with skin. Wear suitable protective gloves and goggles. The usual protective measures for paints must be observed. Process only under good ventilation.
What is the shelf life of the system and what is the best way to store it?
Store in a cool and dry place. With optimal storage conditions, shelf-life should be beyond 12 months. Opening the container several times (and thus absorbing moisture) can shorten the shelf life. Stir individual components before use.
Where can I dispose of residual quantities resulting from use?
Do not dispose of through the sewerage system, on areas of open water or in the soil. Non-hardened remains of the product should be disposed of as hazardous waste. The hardened product waste should be treated as building rubbish or household rubbish.
Do I have to consider the weather conditions when applying the system?
The system is water-emulsifiable and can also be processed in the event of drizzle.
