Product Properties
- Thixotropic, also suitable for grouting concrete paving and slabs
- Water-compatible, enabling dense joints even with narrow gaps
- Single component, ready to use immediately
- Weather-resistant and durable against environmental influences, material will not wash out
- Crack and shrink-free setting
- Water-permeable, allowing rainwater to quickly drain into the substrate; surfaces are not fully sealed
- Frost and weather resistant
Substrate Preparation
- The substructure must be waterproof
- The entire paving construction must be designed according to actual loads and comply with technical standards
- For moderate loads, installation can be carried out in sand, gravel, or crushed stone; for gravel, careful compaction is essential
- Paving stones and slabs should be embedded approximately 1/3 into the gravel bed; additional stabilization with sand or crushed stone may be necessary
- Generally, joint mortar cannot compensate for significant movement of paving stones and slabs
- For higher loads, bonded construction with drainage mortar is recommended
- Ceramic slabs should be back-primed and set in a drainage mortar, with joints designed to be drainage-capable
- Required joint depth
- On non-traffic surfaces, at least 30 mm
- On traffic surfaces, at least 40 mm
- For bedding with drainage mortar and back-priming, at least 15 mm
- During renovation of old paving, joints should be blown out to the required depth, and dirt on the stone edges should be removed
- Before grouting, the surface of the paving or slab layer must be thoroughly rinsed until no water absorption occurs; multiple rinses may be necessary, especially on rough surfaces or in high temperatures
- During application, the surface must not dry out; intermittent moistening is recommended depending on environmental conditions
Application
- Joints from 3 to 8 mm: Apply Prima Paving Joint Mortar 1K onto the wet surface and work into the joints with a firm rubber trowel under pressure, filling the joint space as completely as possible
- Immediately after, actively support the filling process with a water jet; for particularly narrow joints, direct the water jet precisely along the joints
- Settled joints can be immediately refilled with fresh material, ensuring the joint is completely and tightly filled to the bottom
- After applying the mortar into the joints, remove excess mortar from the surface with a soft broom (e.g., coconut broom) thoroughly; sweep diagonally to the joint direction to prevent material removal
- Joints from 8 mm: Apply Prima Paving Joint Mortar 1K onto the wet surface and work into the joints with a firm rubber trowel under pressure, ensuring complete and tight filling to the bottom
- After mortar application, clean residual mortar from the surface with a soft broom thoroughly; sweep diagonally to prevent material removal
- Unused fresh material and mortar residues cannot be refilled into the container and should be covered with a thumb-width layer of water; use within a maximum of 4 weeks
- Apply water to the surface and work into the joints as described above
