• For the formation of drainage channels

Properties

• Effectively prevents the risk of lime bloom
• Good edge adhesion
• Frost-resistant
• Low shrinkage
• Single-component
• Effectively prevents weed growth in joints

Composition

• Cement according to DIN EN 1971
• Trass according to DIN 51043
• Gradated quartz sands according to DIN EN 13139
• Additives for controlling and improving processing and product properties

Substrate

Conditioning

• When paving, the joint depth must be twice the joint width, but at least 30 mm
• For untrafficked surfaces
• An exception are ceramic and fine stoneware terrace coverings laid in bonded construction, where the minimum joint depth is approximately 20 mm
• For trafficked surfaces, the joint depth must be at least two-thirds of the stone height, but at least 40 mm
• Required minimum joint width 5 mm
• Maximum joint width 25 mm

Pre-treatment

• The required joint depth is created by blowing out or chipping out the joints
• The paving surface must be thoroughly cleaned dry afterwards
• The paving surface should be pre-wetted multiple times depending on absorption behavior
• When applying the joint mortar, no water should stand in the joints

Temperature

• Do not process or let dry at air and material temperatures below 5°C or above 30°C, in direct sunlight, or strong wind

Mixing

Preparation

• For manual mixing, first pour the specified amount of water into a clean container and add dry mortar
• Use clean tap water
• Mix the material with a suitable stirrer until homogeneous and free of lumps, then let it mature briefly and remix
• Consistency should be slightly flowable
• For machine processing, adjust water addition to achieve workable consistency
• Do not mix with other products or foreign substances

Processing

• The joint filling is done by pressing in with a rubber float
• Apply the mortar with a rubber trowel under light pressure diagonally across the joint cross-section, ensuring the joints are completely sealed and filled deeply
• Only minimal amounts should remain on the stone surface to facilitate cleaning
• For joints with beveled edges, after cleaning, the joint mortar should only fill up to the underside of the bevel
• Immediately after filling, clean the paving surface
• Check the surface with a thumb test
• Mortar residues on the stone surface must not dry out
• Depending on absorption and surface design, cleaning can be done by:
• Spraying: Depending on absorption, surface design, and temperature, curing time is approximately 1 to 3 hours. Wash the paving with a water hose and a stiff broom diagonally across the joints, ensuring the mortar is not washed out of the joints. Repeat if necessary until the residual film is completely removed. If needed, remove remaining dirt with a high-pressure cleaner after complete curing.
• Washing: Depending on absorption and surface design, curing time is approximately 30 to 90 minutes. Wash the surface with a sponge board diagonally across the joints, ensuring the mortar is not washed out. Change wash water regularly. Repeat until the residual film is completely removed. If necessary, remove remaining dirt with a high-pressure cleaner after complete curing.
• Processing time
• Approx. 15 minutes
• Time references are based on 20°C and 65% relative humidity
• Lower temperatures and high humidity extend processing times; higher temperatures and low humidity shorten them
• Already stiffened mortar must not be diluted with additional water and processed further

Drying and curing

• The fresh mortar must be protected from rapid drying and adverse weather conditions such as frost, drafts, direct sunlight, and heavy rain, possibly by covering with foil
• The paving surface is walkable after about 3 hours and fully loadable after approximately 28 days
• Time references are based on 20°C and 65% relative humidity
