Step-by-Step Application Guide

 

Prepare

Joints must be cleaned of weeds, roots and loose and the surfaces clean of dirt and debris.

depth need to be of at least 25 mm (2/3 of the stone height for traffic load). Adjacent areas that are not to be grouted should be masked or covered. To avoid settling and loose stones, we recommend a permanent water-permeable and load-bearing substrate corresponding to the
subsequent load (pay attention to the current standards and guidelines). We generally recommend the bonded
construction method.

Pre-Wetting

Pre-wet the paving surface thoroughly with clean, cold water. Warm or highly absorbent stone may require extra water.

Mixing Buckets

Open the bucket. Pour the bottle inside completely to the sand component. Fill the emptied bottle
to ¼ = 0.25 liters of water and close it, shake vigorously and add to the mixture. Make sure the bottle is
completely empty. Use a professional stirring or mixing device. Start mixing process and mix thoroughly for
at least 6 minutes until a creamy, flowing mass is obtained. No further addition of water is necessary.

Mixing Bags

Open the bag and pour the sand into a suitable mixing container. Add the contents of the separately supplied
bottle containers completely. Fill the emptied bottles with 0.5 litres of water each and cap them, shake
vigorously and add to the mixture. Make sure that the bottles are completely empty. Use a professional stirring
or mixing device. Start the mixing process. After 3 minutes mixing time, add another 2.5 litres of water and
mix thoroughly for an additional 3 minutes until a creamy, flowing mass is formed.

Fill the Joints

Pour the finished mixture onto the well pre-wetted surface. Work in the jointing compound carefully and as
diagonally as possible to the joint using a rubber squeegee. To make the most of the flowability, it is recom
mended to divide this mixture into two to three portions. Mix the remaining joint compound again briefly.
Keep the surface constantly wet during this work.

Clean the Surface

After approximately 10-20 minutes, sweep the stone surface carefully into the joint with a medium
coarse broom. If a white gel-like streaks form on the stone surface, then the sweeping time wasn’t long enough. Remove the remaining mortar residues with a fine coconut broom. grout that has been
swept off should no longer be used. Be aware that chamfers (beveling of the side edges) on pavers
must be exposed.

Aftercare

Protect the surface from rain for 12–24 hours.

• Walkable after 24 hours
