A stable, load-bearing structure, a water permeable sub-base and the paving layer must all be correctly designed and installed for the anticipated traffic loads. Joint depth min. 30 mm (full joint depth in trafficked areas), joint width: > 3 mm, Ambient and substrate temperatures min. 3°C / 37,4°F, max. 25°C / 77° F.
A drill with spherical mixing paddles, a water supply, a hose with spray nozzle, a squeegee and a coconut fibre brush.
On some reconstitued or sensitive natural stone paving, the vdw 815 binder contact can make the stone appear darker or to have a 'wet look'. Therefore always apply a test area first.
Clean the surface thoroughly of all dirt, cement residues, vegetation, organic material or other contaminants.
Fully saturate the surface of the paving.
Pre-mix the vdw 815 resin coated aggregate (component A) material in the pail. Then add all of the vdw 815 liquid hardener (component B) from the bottle in the pail and mix with the drill and sphericalpaddel mixers, until smooth and homogenous. Any material that is not thoroughly mixed must not be used.
No water should be added to the mix.
Filling the joints:
Apply immediately after mixing by pouring directly onto the pre-wetted surface. Work the material thoroughly into the joints using the rubber suqeegee, whilst spraying lightly with water from a hose. The product is very free flowing. The paved area must be kept constantly wet during application. We recommend working from the highest to the lowest points.
Remove any excess mortar residue from the area after about 5 min. (immediately at temperatures over 15°C/59°F) by spraying lightly with water from a hose at a distance of about 25cm. Avoid washing out the joints. Be careful to clean the paved surface towards areas not yet jointed and do not allow any water containing residues to pond, stand, dry-out or run-off over completed areas. Finally, remove any remaining fine residues to pond, stand, dry our or run-off over completed areas. Clean brush in water frequently. Chamfered edges must be brushed free.
Cordon off the freshly applied areas for a period of at least 24 hours, or until the paving surface is no longer tacky. Then the areas can be walked over. The are can be fully released to vehicular traffic after 3-5 days, when fully hardened.
