vdw 850

vdw 850 is the 'stat-of-the-Art' high performance and extremely durable, self compacting, epoxy bound paving jointing mortar for pedestrian, light and medium vehicular traffic loads, including larger vehicles and mechanical road sweepers, cleaning with high pressure water jetting etc, etc.

vdw 850 Paving Joint Mortar / Grout is designed for extremely fast self compacting aplication, with no delays (and no additional costs!), or waiting for the weather, even in continuously wet weather and at colder temperatures. This is because the material can be applied in the wet, even in the rain - and in cold (non-freezing) conditions, when vdw 850 can still be applied as it will continue to cure when the temperature increases again above 8-10 degrees C.

A big advanyage of vdw 850 on UK paving projects is that its performance is not reduced by residual water and damp in the joints when it is applied - unlike any form of traditional or prepacked cement based joint mortar which will shrink and then crack due to the change in water to cement ration - vdw 850 does not shrink due to its unique water dispersed epoxy resin bound sand formulation.

vdw 850 is non staining, it is superb at preventing weed growth or damage by boring insects. It is also fully resistant to de-icing salts and freeze-thaw conditions.

Quite simply the best paving jointing mortar on the market and the clear global paving joint technology leader!

vdw 850 is the ideal paving jointing mortar for use with natural stone, reconstituted stone and concrete block, slab and other paving surfaces on quality natural patios, driveways and paved roadways, including road junctions and intersections or roundabouts, town centres, paving around retail and commercial developments, plus all sorts of other paved domestic, commercial and public landscaping areas.

vdw 870 Jointing Sand Stabiliser
GftK's vdw 870 is an acrylic resin based paving jointing sand stabiliser that provides a very useful lower cost and easy to use, water dispersed and environmentally friendly solution for domestic paving sand stabilising applications, such as on patios and pathways or driveways with light vehicles (normal domestic cars and bikes etc.)

Application of the vdw 870 is simple - after compacting the sand into the joints the vdw 870 is spray applied and then any excess is carefully squeegeed to uniformly cover and penetrate the sand filled joints and then any excess is carefully sponged off. Note: Acrylic sand stabilisers are not designed for use in heavily used commercial or vehicular trafficked areas, or use with a aggressive mechanical or high pressure water cleaning regimes.

GftK vdw 950 StainProtect plus 3-in-1
Vdw 950 StoneProtect plus – 3 in 1 is a special, ready to use, water based impregnation for hydrophobic (water repelling) and oleophobic (oil repelling) treatment of natural stone and other porous paving substrates. This is probably the best and the easiest to use all-round 'invisible sealer' for natural stone and quality concrete block paved surfaces

Ic can also be used before grouting the paving to reduce any residual cement or resin binder film on sensitive surfaces

vdw 950 StoneProtect plus 3 in 1 reduces the absorbency of the treated paving and largely prevents water, oil and grease penetration. Any spillages or contamination remains on the surface and the area is therefore easier to clean. The colour of the paved surface is not significantly changed, if at all, although a few very sensitive substrates may look darker.

Application should be on clean, absorbent and dry paved surfaces that are ready for pointing, with dry weather conditions and no rain or heavy dew forecast for at least 24 hours. Apply vdw 950 StoneProtect plus 3 in 1 with a suitable brush or roller evenly to saturate the surface, but avoiding any residual ponding or puddling.

Protect the area treated with vdw 950 StoneProtect plus 3 in 1 from moisture and any other dirt or surface contamination for a minimum of 5 hours (at 20°C and 65% relative humidity).
