This ready-to-use, water-permeable jointing mortar prevents weed growth in joints and hardens through contact with atmospheric oxygen. This allows grouting in light rain or damp weather.
The jointing mortar is resistant to frost and de-icing salt. The lasting flexibility prevents cracking after curing. This makes the product ideal for grouting large-format tiles on terraces and walkways.
A-Joint® Ready Flex can be used for almost all ceramic coverings, as well as coated and sensitive stone surfaces.
Suitable for almost all ceramic tiles, as well as coated and porous tiles.
Suitable for paving with light loads:
- Traffic-free shopping streets
- Footpaths and cycle paths
- Driveways
- Garden and walking paths
- Terraces
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
Remove the vacuum bag from the bucket, cut it open and spread the compound evenly over the well pre-wetted surface. Work the paving joint mortar intensively into the joints with a rubber squeegee and a soft water spray. When filling, make sure that the stone surface does not dry out. The joints must be completely filled and compacted. Sunken 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.
