Application Instructions for Xtreme Ceramic (VDW 815 Plus)

1

Construction Site Requirements

  • A stable, load-bearing structure, water-permeable sub-base, and a bedding layer
    • We recommend the PHNA Xtreme Trass Bedding Compound (vdw 480)
  • Must all be correctly designed and installed for the anticipated traffic loads and in accordance with ASTM.
  • The PHNA 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 PHNA Xtreme Easy jointing compound can be applied on damp / wet paving and even in light rain.

2

Preparation

Preparation / Pre-wetting:

  1. 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.
  2. We recommend a pre-treatment with the PHNA Xtreme Stone Protect 3-in-1 (vdw 950) for any porous and/or sensitive paving surface
    • Please allow at least 24 hours after application prior to grouting.
  3. Thoroughly pre-wet the surface of the paving and mask adjacent surfaces which are not to be jointed. Always use clean, fresh tap water!

3

Mixing & Filling the Joints

  • Open your bucket of PHNA Xtreme Easy jointing compound and cut open the vacuum-sealed packaging.
  • Pour the PHNA 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 PHNA 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 PHNA Xtreme Easy is chlorine and chemical resistant, but we do not recommend using it around swimming pools for other reasons.
    • We Recommend instead our Xtreme Ceramic, Xtreme, or Xtreme Plus jointing compound.
