A-Joint® Ready prevents weed growth in the joints and is suitable for nearly all natural stone and concrete paving surfaces used outdoors.
The jointing mortar is resistant to frost and de-icing salt. Moreover, you can even continue grouting in light rain.
Thanks to its easy application and self-compacting properties, this paving grout is also ideally suited for enthusiastic home improvers.
A-Joint® Ready can be used around the house, on footpaths, terraces, courtyards, and driveways with passenger vehicle traffic.
Suitable for a traffic load of up to 3.5 tonnes:
- Footpaths
- Terraces
- Driveways
- Cycle paths
- Garden and walking paths
Step 1: Preparation
The joints must be cleaned out of weeds, roots and loose parts to a depth of at least 20 mm. The surface to be jointed must be cleaned from any dirt. Adjacent surfaces that are not to be jointed should be taped off or covered. To avoid sinking surfaces and loose stones, we recommend a permanently water-permeable and load-bearing substrate corresponding to the loads, that later go over the surface.
Step 2: Pre-wetting
Pre-wet the entire surface extensively. Higher soil temperatures and absorbent, open-pored stone require more intensive pre-wetting. Generally, use clean and cold water.
Step 3: Filling the joints
Take the vacuum bag out of the bucket, cut it open and spread the compound evenly over the well pre-wetted surface. Work the paving grout intensively into the joints with a broom or rubber squeegee. The joints must be completely filled and compacted. By dosing the fresh mortar with a fine water spray, you increase the strength of the joint and narrower joint widths can be filled more easily. Avoid standing water in the surface during application. Sagged joints must be refilled with fresh paving joint mortar immediately.
Step 4: Cleaning the surface
Directly after filling the joints, carefully clean the stone surface with a medium-coarse street broom diagonally across the joint. Remove all residues of the paving mortar from the stone surface. Do not reuse any material that has been swept off. Be aware that chamfers (bevelling of the side edges) on slabs and pavers must be exposed.
Step 5: Aftercare
Protect the freshly jointed surface from continuous or heavy rain for 12-24 hours. We recommend construction foil or tarpaulins as rain protection. These can be laid directly on the surface.
At temperatures around 20°C, the surface can be walked on after 24 hours and is fully loadable after 6 days. Low temperatures and high humidity can extend the complete curing time up to several weeks.
Cleaning work (high-pressure cleaner max. 100 bar, min. 30 cm distance) may be carried out after 7 days at the earliest.
