tile and stone adhesive

standard
In Compliance With
EN norms – EN R2T & ISO 13007

 

Calcibond Ultima (Drywall adhesive) is a unique Eco-friendly, very high flexible & elongation of 30 mm., two-part POLYURETHANE ADHESIVE based on high-quality minerals and ready to use drywall adhesive for doing work on flexible surfaces, external facade, areas under heavy vibration, heavy-duty Industrial floor, metal & wood surfaces including all kind of dry- wallboards to fix all kind of large format & slim tiles slabs, natural stone and re-composed stone material. Suitable for internal & external area.

Ultima Hi-Tech Features

Wallnut High Grip Technology
Wallnut High Flexible Technology
thermal
Wallnut application thickness
  • The supreme bond between plywood systems including heavy-duty marine-grade plywood.
  • Guaranteed performance to fix large format tiles & stone, slim slab, stone slab which is sensitive to moisture, and re-engineered stone based on resin system.
  • Best for flexible surfaces and areas under continuous movement such as high-rise facade under wind & temperature pressure, public infrastructure, etc
  • Deformability of >10 mm., hence can be used on most flexible surfaces.
  • Freeze-thaw and thermal shock resistance

 

  • Best performance even at a low thickness of 1.5 mm. Can be used up to 6 mm, or more

Surface Preparation

How to apply
  • Stable structure of the metal, marine-grade plywood, Vinyl PVC & rubber surfaces.
  • Existing surfaces of Epoxies & PU coating.
  • All kinds of drywall boards are made with cement-based, wood particle, gypsum, calcium silicate, etc.
  • Fully dry and sound new or old traditional plaster.
  • Existing tiles or stone surfaces.
  • New or old absorbent IPS or PCC floors that are sound and stable.
  • Screed made with Wallnut Zeorich Base, Zeorich Base Rapid, or similar kind.
  • Fully cured Stable concrete of all types including precast concrete
  • Surfaces are made with AAC (Autoclaved Aerated Concrete) panel,
  • All kinds of ceramic & vitrified tiles of all sizes including tiles made in metal and wood.
  • All kinds of natural stones which are sensitive to moisture, stone veneer, slate stone, laminated stone, Corian solid surface, Onyx stone & agglomerated re-engineered resin-based quartz stone.
  • Large size slab of tiles & stone bonded with fibreglass mesh on the back surface.
  • All types & sizes of ceramic & glass mosaic. Slim Tiles slab in 3 mm. thicknesses or cut stone with minimal thickness.
  • Ensure that surface is sound, clean and free from all foreign material such as oil, grease, dust etc.
  • If the surface is uneven by more than 15 mm. then first do the levelling by using the correct levelling material in order to avoid using the excess thickness of adhesive.
  • Do not pre-wet the surface with water.
  • If the surface area is larger, provide movement joint with every 3 meters or as per local standard.
  • In case working on an external façade, avoid direct sun exposure to the surface and to finishing material. Let cool the surface before starting the application. A hot surface may compromise the final performance.
  • Follow the concrete expansion joint and connection joint as per standard.
  • Open Calcibond Ultima (drywall adhesive) mono pack. Mix the full quantity of part A hardener into Part B thick paste. Use a slow speed electric stirrer until it becomes a homogeneous paste. Manual mixing can compromise the performance of adhesive.
  • In case part quantity of drywall adhesive is to be mixed, it is advisable to use strictly the correct ratio of Part A: Part B (1:10). For taking the correct ratio, a measurement jar can be used. (In case Part A & B mixing ratio are not correct, the final result may vary and adhesive performance can be compromised.)
  • Use the mixed material within the pot life period
  • Spread the drywall adhesive in desire thickness onto the surface using Wallnut notch trowel.
  • Once the drywall adhesive is applied, fix the tiles or stone onto adhesive before skin formation and press firmly. In case tiles or stones are of big size, also apply the adhesive layer at the backside.
  • In case using as a spot bonding, ensure that a minimum of 25 per cent of tiles or stone surface is covered with adhesive.
  • Leave the space between tiles or stone to have proper grouting and to accommodate surface movement.
  • Leave the tiles or stone for 24 hours to bond well and follow the grouting with Wallnut Connect & Lock Epoxy Grout
