What is VDW 495 Joint Compound Adhesive Mortar?

The PHNA Xtreme Adhesion Elutriant is a high-strength, highly plastic-modified, hydraulically hardening universal bonding compound used to secure pavers, natural stone, and porcelain tile to the PHNA Xtreme Bedding Compound (VDW 480 Trass Bedding).

Benefits of VDW 495 Joint Compound Adhesive Mortar

Fast hardening

This combination of a wet to wet application system is that as it dries, it dries quickly. This allows projects to be completed faster because testing and grouting can be started earlier.

Suitable for use with under-surface heating

This Elutriant is suitable for use with under surface heating. While also being permeable, allowing surfaces to dry and be warm without shifting or cracking.

Surface can be opened After 24 hours

Like with how fast this elutriant hardens. Once the project is completed, it can be opened for traffic and to public use after 24 hours. This means projects are completed faster, getting you on to the next project faster.

For light to heavy traffic loads

This Elutriant can used on surfaces suited for traffic loads, accommodating light to heavy loads.
This is used to create a monolithic permeable system that will last the test of time.

Xtreme Adhesion Elutirant Mixing and Installation Instructions

1. Construction Site Requirements

The subsurface must be made load-bearing, firm, and water-permeable.
All elements should be constructed based on the highest expected traffic loads.
The foundation should be stable so as not to allow any future surface settling or loosening of pavers under these traffic conditions.
Ideally, the setting bed would be the PHNA Xtreme Bedding Compound (vdw 480).
Ambient and substrate temperature should be 41-77°F, and the process should be carried out in dry weather.

2. Preparation

To ensure a clean bond between the Xtreme Adhesion Elutriant and the paving unit,
the connecting elements should be clean and free of any dust/debris that would otherwise prevent that.

3. Mixing

RECOMMENDED MIXING RATIOS

Notched Trowel Method

25 kg | 55 lb. bag of Xtreme Adhesion Elutriant to be mixed with approx. 5 liters (1.3 gal.) of cool, clean water
Mixing partial quantities to be used in the specified processing time is recommended.

“Dip” Method

This method should only be used for cobblestone installation.
25 kg | 55 lb. bag of Xtreme Adhesion Elutriant to be mixed with approx. 7 liters (1.8 gal.) of cool, clean water
Mixing partial quantities to be used in the specified processing time is recommended
According to the specified mixing ratios, pour the requisite amount of water into a container.
Add in the proper proportion of the Xtreme Adhesion Elutriant.
Mix the slurry with a suitable drill/paddle mixer for 2 minutes until homogeneous.
Let the mixture mature for 2 minutes before briefly mixing again.
- Hardened mortar must not be made workable again.

4. Application

Installation of paving units with the Xtreme Adhesion Elutriant bonding slurry can be carried out in one of two ways and should be done based on the type of paving unit utilized.
For natural stone slabs, porcelain tile, and concrete pavers,
- Please follow the “Notched Trowel.” method.
For small paving units such as cobblestones.
- The “Dip” method is a viable alternative.

Notched Trowel Method

A 1/4″ x 1/4″ notched trowel is recommended.
Using the notched trowel, apply the Xtreme Adhesion Elutriant slurry to the clean underside of the paving unit, ensuring it covers it completely.
Any spillage onto the sides of the paving unit should be immediately wiped clean with a damp sponge or cloth
- this will provide a clean joint for the jointing compound that will later be used.
The paving unit should be immediately laid in the still-fresh drainage mortar (“wet-to-wet”),
and solidly set into place with the use of a rubber mallet or dead-blow hammer.
The Xtreme Adhesion Elutriant must be protected from rapidly drying out.

“Dip” Method

Dip the paving unit 3/4″
1 1/4″ deep into a tub of the Xtreme
Adhesion Elutriant.
Then hammer the paving unit into the still-fresh
drainage mortar using an appropriate rubber mallet or dead-blow
hammer.

5. Important Information

The surface can be walked on after 24 hours.
Grouting can also be carried out at this time.
Protect the mortar from rapidly drying out, as well as rain, for 12 hours.
Full resilience will be reached after 7 days, but vehicular areas should not be opened to traffic until the grout has also sufficiently cured.
Paved stone work is done by hand – no compaction machinery should be used.
Expansion joints should be laid according to relevant guidelines.
The underside of sawed stones should be roughened prior to the application of the Xtreme Adhesion Elutriant.
