GftK vdw 800 Paving Joint Mortar

The climate of the area around Cologne is also a difficult environment for paving jointing, as the materials have to cope with significantly higher than the UK temperatures in summer and significantly lower temperatures than most of the UK in winter, both conditions when all types of conventional paving joint solutions are difficult to apply and install, as well as prone to premature failure.

This illustrate that right from the very beginning, GftK’s vdw 800 has been designed to be suitable for use in difficult conditions and with small small and larger format paving of almost all types of natural stone in domestic, commercial, and public paved areas. The vdw 800 paving joint mortar can safely and securely accommodate pedestrian and light to medium vehicular traffic loads (cars and vans etc).

The mortar is supplied in 2-components including epoxy resin pre-coated quartz sand, to which the hardener and a measured amount of water is added, then mixed in the pails supplied, to a uniform, fully homogeneous colour, and consistence. The freshly mixed mortar is then easily and quickly applied using wet-slurry application techniques across the thoroughly pre-dampened surfaces. This is done standing-up in an ergonomic position, by rubber squeegees, so that the mortar effectively self-compacts into the joints. Apply more water from a hose where necessary to keep the paving wet and the mortar flowing. After an initial few minutes (around 15mins @ 20օ C​), the surface is finished using a soft coconut bristle brush frequently dipped in clean water to remove any excess.

As the vdw 800 is always applied to pre-dampened surfaces, one more advantage is that it can be applied shortly after wet weather, without waiting for the areas to dry after rainfall, although with vdw 800 the surface must be covered if more rain is expected to prevent resin run-off. Alternatively you could use the latest state-of-the-art development GftK’s vdw 850+ that can even be applied in the pouring rain e.g. when needs must to finish a job and/or get paid!
