GFTK VDW 840 Xtreme Easy Jointing Compound

Why Use VDW 840 Xtreme Easy Jointing Compound?

The VDW 840 plus Xtreme Easy is a pre-mixed, 1-component resin paving joint compound suitable for concrete pavers, natural stone, and tile. 

Application Instructions for GFTK VDW 840 Plus Xtreme Easy

1. Requirements

• A stable, load-bearing structure, water-permeable sub-base, and the bedding layer
• We recommend the GTFK Xtreme Trass Bedding Compound (VDW 480)
• Must all be correctly designed and installed for the anticipated traffic loads and in accordance with ASTM.
• The GFTK VDW 840 Xtreme Easy jointing compound is designed for the quick and easy grouting of concrete pavers, ceramic tile, and natural stone.
• The Xtreme Easy cannot be used to compensate for any settlement of the substructure.
• Movement joints must be installed as necessary to comply with the required structural design and any anticipated levels of movement.
• The GFTK VDW 840 Xtreme Easy jointing compound can be applied on damp/wet paving and even in light rain.

2. Preparation

• Clean the surface thoroughly of all dirt, cement residues, organic materials, or any other possible contaminants, including cleaning out all of the joints to the required depth.
• We recommend a pre-treatment with the GFTK Xtreme Stone Protect 3-in-1 (VDW 950) for any porous and/or sensitive paving surfaces.
• Please allow at least 24 hours after application prior to grouting.
• Thoroughly pre-wet the surface of the paving and mask adjacent surfaces that are not to be jointed.
• Always use clean and fresh tap water!

3. Filling the Joints

• Open your bucket of GTFK VDW 840 Plus Xtreme Easy jointing compound and cut open the vacuum-sealed packaging.
• Pour the GTFK VDW 840 Plus Xtreme Easy jointing compound directly onto the pre-wetted surface in small piles.
• Add water to the material using a gentle water spray, and work the self-compacting material thoroughly into the joints using a rubber/foam squeegee and/or stiff broom.
• If the viscosity of the product diminishes, re-moisten by spraying lightly with water from a hose.
• The paved area must be kept constantly wet during application.
• We recommend working from the highest to the lowest points. All tools and shoes should be regularly cleaned with water.

4. Cleaning off

• Remove any excess GTFK VDW 840 Plus Xtreme Easy jointing compound residue from the area by spraying lightly with water from a hose.
• 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, or dry out on the completed areas.
• Finally, remove any remaining fine residues with a damp Coconut fiber brush – do not brush any residual dry material into any unfilled joints.
• Chamfers must be brushed free carefully, as performance cannot be guaranteed on these.
• Clean this brush in water frequently.

5. Important Information

• Remain off the freshly applied areas and protect them from heavy rain for a period of min. 24 hours, or until the paving surface is no longer tacky.
• Then, the areas can be walked over.
• In general, a strength test should be carried out before final clearance of the area after 7 days.
• A very thin film of the resin binder may remain on rough surfaces or any surfaces that are not cleaned thoroughly.
• This film will disappear after a period of exposure to traffic and weathering.
• The GTFK VDW 840 Plus Xtreme Easy is not recommended for use around swimming pools – we instead recommend our Xtreme Ceramic, Xtreme, or Xtreme Plus jointing compound.
