A-JOINT® READY FLEX is a ready-to-use, vacuum-packed, fine-grained jointing mortar with excellent flow properties, ideal for narrow joints from 3 mm.

A-JOINT® READY FLEX prevents weeds from growing in the joints, is water-permeable, frost-resistant and cures on contact with oxygen in the air. Thanks to its long-lasting flexibility, it is ideal for grouting large-format slabs on patios and paths.

A-JOINT® READY FLEX can be used on almost all ceramic tiles as well as on coated and delicate stone surfaces.

Processing instructions

Prepare:

The joints must be cleaned out of weeds, roots and loose parts to a depth of at least 20 mm without
leaving any residue. 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.

Pre-wetting:

Pre-wet the entire surface extensively. Higher surface temperatures and absorbent, open-pored stones
require more intensive pre-wetting. Generally, use clean and cold water.

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.

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

After-treatment:

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 tempera-
tures 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. Due to
raw material light sanding of the mortar surface is possible. A strength test is always recommended
before use. Cleaning work (high-pressure cleaner max. 100 bar, min. 30 cm distance) may be carried
out after 7 days at the earliest.

Resin film: After jointing with A-JOINT®READY FLEX, a thin resin film remains on the stone surface (in case of
insufficient watering), which intensifies the stone colour and protects it from dirt. This resin film usually disappears over
time due to weathering and use of the surface. In case of doubt, create a small sample surface before jointing the entire
area. The resin film is not a design defect, as neither the quality nor the functionality of the joint is affected.

Please take note of technical leaflet and safety data sheet.

Application notes: Use A-JOINT®READY FLEX only with a stable, load-bearing and permanently water-permeable
substructure or a slope of at least 2%. In this regard, take into account the current regulations for the construction of
terraces and paths. Do not use in permanent wet areas e.g. pools, fountains or drains. A-JOINT®READY FLEX has an
unique smell which disappears over time after complete hardening. Application is recommended only in well ventilated
outdoor areas. We draw attention to the wearing of adequate protective work clothing. Shoes and tools must be free
from dirt and should be cleaned with water during and after application.

Regularly remove dirt, leaves and moss from the joint surface.
