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. vdw 800 is a paving joint mortar and cannot be used to compensate for any settlement of the substructure, or for the sealing and waterproofing of any surfaces. Movement joints must be installed as necessary to comply with the required structural design. The vdw 800 mortar can be applied on damp/wet paving and in high humidity conditions.
In pedestrian areas: It is acceptable to lay the paving on a fully compacted and stable, permeable sand or gravel bed. However, it is always better and more durable in a permeable concrete or mortar bed, otherwise increased cracking may occur. The paving should be laid as directed by the manufacturer as stated in BSI (Building Stone Institute) Recommended Best Practices.
In vehicular traffic areas: The paving should be laid on a permeable concrete or mortar bed in accordance with the relevant traffic loads andBSI (Building Stone Institute) Recommended Best Practices.
The ambient, substrate and material temperatures should be min. 44,6 °F to max. 77 °F.
Tools: A compulsory forced action mixer or a drill with twin spherical mixing paddles for smaller projects. Water supply, a hose with spray nozzle, a squeegee and a coconut fibre brush.
Test area: On some reconstituted or sensitive natural stone paving, the vdw 800 binder contact can make the stone appear darker or to have a ‘wet look’. These effects are not defects in the product or shortcomings in the execution of the work. In general the product should be tested first!
Preparation / Pre-wetting: Clean the surface of all dirt, cement residues, organic materials or any other contaminants, including cleaning out all of the joints to the required depth. Fully saturate the paved surface before starting the application and ensure this condition is maintained throughout the work. The amount of wetting required is related directly to the type and porosity of paving and the site conditions i.e. wind, direct sunlight and temperature etc.
Mixing: Mix the vdw 800 resin coated aggregate (component A) materials together, and then add the vdw 800 liquid hardener (component B) from the bottle in the bucket. Then add a quantity of clean water equal to double the quantity of the liquid hardener (use the empty component B bottle as a measure), and mix to achieve a fully homogeneous consistency. Mixing time: min. 5 minutes.
Filling the joints: Spread the vdw 800 mortar across the
pre-wetted paving surface using the rubber squeegee and work thoroughly into the joints where it self-compacts. We recommend working from the highest to the lowest points. Brushing off: After approx. 15 – 20 minutes the vdw 800 mortar should have achieved a semi-dry consistency. At this stage, remove any excess mortar completely using a damp coconut fibre brush. Frequently clean this brush in water and then rinse the surface by spraying lightly with water from a hose at a distance of about 0.98 inch. Avoid washing material out of 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. Do not brush any residual, cured mortar into any unfilled joints. Cordon off the freshly vdw 800 jointed areas for a period of at least 12 hours after which the areas can be walked over. Protect the freshly laid area from rain or waterflow for a period of at least 12 hours (do not place the covers directly onto the paving: ensure that the air can circulate freely over the surface). The area can be fully opened for use by vehicular traffic after 7 days. Tools can be cleaned with water whilst the mortar is fresh. Chamfered edges must be brushed free of the vdw 800 mortar. Cured mortar can only be removed mechanically.
Consumption: The table below refers to areas of natural stone sets with cropped edges and has been compiled from our own experience. The natural shape of setts and different designs or techniques, may result in variations. There is no allowance for any loss or wastage, etc. If in doubt, always determine actual consumption on a test area.
