GftK vdw 850 Epoxy Paving Joint Mortar is high performing and hard wearing, suitable for natural stone, reconstituted stone and concrete block paved surfaces on driveways, roads and other trafficked paved areas, including those used by delivery vehicles etc.
vdw 850 is a two part jointing compound in which a liquid hardener is added to a resin coated aggregate. The unique water dispersed epoxy resin bound sand formulation means that, unlike traditional cement based jointing mortar, vdw 850 does not shrink and crack as it dries.
Tubs are 25kg and available in two colours; sand and stone grey.
Why use vdw 850 as a jointing mortar?
• Fast, durable, cost effective

• Can be applied in the rain
• Clean, stain free surfaces
• Water permeable
• Optimum strength correlation
• Suitable for pressure washing
• Excellent abrasion resistance
• Resistant to frost, freeze-thaw and de-icing salt
• No weeds or boring insects
• Environmentally friendly
• Also ideal for paving refurbishment
How to apply vdw 850/ 815
We recommend that 2-3 people carry out the pointing to ensure you keep the area nice and wet and sweep the mortar into the paving joints and remove excess.
- Fully saturate the area to be grouted prior to the application of the vdw 850/815.
- Pre-mix the base component of the material (epoxy coated sand).
- Add the bottle of resin hardener and mix for a minimum time of 3 minutes.
- Pour and apply the mixed material onto the pre-saturated area using a rubber squeegee, whilst lightly spraying with water from a hose onto the material (the area must be kept constantly wet during the application).
- After about 5 minutes ( immediately in higher temperatures ) remove any excess mortar residue by spraying lightly with water from a hose, at a distance of 25cm.
3. Brushing off
- After a few minutes remove any excess mortar residue from the area, using a clean damp soft coconut brush (clean the brush frequently with water).
- Protect the area for a minimum period of 24hrs, or until the mortar joints are no longer tacky.
- A thin layer of resin can remain on the paved surfaces if they are not rinsed and cleaned thoroughly, if such a film is left, it is not a defect and will disappear after a period of time due to normal weathering and traffic exposure.
