ROMEX Adhesion Elutriant Bonding Slurry, 55 lb Bag, Trass Cement
About That Name
Adhesion Elutriant is the official ROMEX North America product name, so that is what we list it under and that is what you will find on the data sheet. It is also a translation artefact. The German original is Haftschlämme, which means adhesion slurry, and ROMEX’s own German site translates it correctly as a bonding slurry. An elutriant, in real English, is a liquid used in a laboratory particle separation process, which has nothing to do with this. If the name has confused you, that is why.
Where It Sits in the ROMEX System
This is the middle layer of a bonded, rigid paver build up, and it is not interchangeable with the other ROMEX products.
| 1. Bedding | ROMEX TRASS BED, the permeable bedding mortar the paver sits on |
| 2. Bonding slurry | This product, on the back of the paver |
| 3. Set the paver | Into the wet bed, and do not lift it again |
| 4. Joint | ROMEX ECOFINE or another ROMEX jointing product, applied last |
Mixing and Application
| Bag | 25 kg, about 55 lb |
| Water, trowel consistency | About 8 litres, 2.1 gallons, per bag |
| Water, dipping consistency | Slightly more, about 0.25 litres per kg |
| Trowelled layer | 3 to 5 mm onto the damp underside of the stone |
| Trowel | 1/4 inch notched, or 3/8 inch for rough or uneven undersides |
| Dipping depth | 2 to 3 cm for cobbles |
| Composition | Polymer modified, trass cement |
Rules That Matter
- Do not lift a paver off the bed and re-set it once it is placed. The bond is made wet on wet and cannot be remade.
- The underside of the stone must be damp, not dry and not wet.
- Install between 41 and 86 F, and during cure protect from below 41 F and above 77 F.
- Do not install on frozen ground.
- Protect from rapid drying, drafts, direct sun and rain while it cures.
Figures ROMEX Does Not Publish
Coverage, pot life, open time and cure time are not published by ROMEX for this product. One Canadian distributor quotes 85 sq ft per bag, and we mention it only so you know where that number comes from. Real yield depends entirely on your trowel notch and how rough the paver backs are. If you need to order against an area, call us and we will work from the paver format rather than a borrowed figure.
