vdw 840 plus

vdw 840 plus 1K-FugenMörtel is the slurryable, ready-mixed joint mortar for areas with foot traffic: just open the bucket, cut open the PE film, distribute in partial quantities on the area, slurry in with water, sweep off, done! Specially for factory-impregnated or sealed surfaces. Suitable for natural stone and concrete stone paving, slabs and clinker surfacings on garden paths, in house entrance areas and on patios with purely pedestrian loads.

• can be slurried in with plenty of water, without loss of quality
• self-compacting effect
• workable in light rain
• almost binder-free surfacings
• ready to use
• suitable for ceramic terrace elements

Application

Compared with the usual air-oxygen-curing 1K joint mortars, vdw 840 plus 1K-FugenMörtel is distinguished by higher strength and the possibility of slurrying the mortar in by means of a water jet.

Requirements Stable and permanently water-permeable substrate. Joint depth ≥ 30 mm, joint width min. 3 mm, max. 20 mm, exterior and object temperature ≥ 5 °C, max. 25 °C.

Tools Knife, hard-rubber squeegee, coconut broom and water hose with spray nozzle.

Test area With natural and concrete stone paving, contact between vdw 840 plus 1K-FugenMörtel and the stone surface may cause visual changes. In general we strongly recommend laying out a test area.

Filling the joints Cut open the PE bag. Pre-wet the surface thoroughly. Then distribute the mortar portion by portion on the area and slurry it into the joints with a soft water jet and hard-rubber squeegee. Clean excess mortar residues off the paving surface with a water spray jet, without washing out the joints. Sweep off the paving surface with a damp coconut broom and smooth the joint surface in the process. Chamfers must be swept clear.
