The ultimate polyurethane adhesive — for large format tiles, stone slabs, facades, metal, wood & drywall. India's highest-performance tile fixing solution.
What Makes Ultima
The Best
Calcibond Ultima is a unique eco-friendly, very high flexible two-part POLYURETHANE ADHESIVE — with elongation of 30mm for the most demanding installations.
Guaranteed performance on heavy-duty marine-grade plywood systems — the strongest bond available for wood-based substrates.
Deformability of >10mm for continuous movement — high-rise facades under wind and temperature pressure, public infrastructure, vibrating floors.
Full thermal shock resistance for external applications — withstands extreme temperature swings without compromising adhesion.
Best performance at as low as 1.5mm thickness — usable up to 6mm or more, giving complete control over bed depth.
Super flexible polyurethane-based system with superior performance under high ageing — designed for a building's full service life.
Acts simultaneously as waterproofing membrane and tile adhesive in wet areas — highly water-resistant, ideal for pools and wet rooms.
Fixes all large format tiles, slim tile slabs (3mm), natural stone sensitive to moisture, re-engineered resin-based quartz stone.
Pure white formulation for very light-coloured natural stone including Australian White and other transparent or translucent materials.
Technologies
High initial grab with extended open time for demanding commercial installs
Transverse deformation ≥10mm for continuous movement zones
Anti-slip system for vertical surfaces, facades and overhead applications
Tensile adhesion >3 N/mm² — superior bond in pools, wet areas & facades
Where Ultima Performs
Internal & external floor and wall, including high-rise facades under wind and temperature pressure.
Kitchen & bathroom countertops in residential and commercial buildings of all scales.
Chemical-resistant areas — laboratories, industrial kitchens, staircases, and heavy-traffic areas.
Railways, airports, stadiums, bridges and other public infrastructure under continuous movement.
Large-size swimming pools, Jacuzzi and saunas for public use — fully waterproof and chemical resistant.
Operating areas like dado walls, lifts, and any areas with heavy public movement requiring superior flex.
How to Use Ultima
- Stable structure of metal, marine-grade plywood, Vinyl PVC & rubber surfaces
- Existing surfaces of Epoxies & PU coating
- All kinds of drywall boards — cement-based, wood particle, gypsum, calcium silicate
- 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
- Fully cured stable concrete including precast concrete
- Surfaces made with AAC (Autoclaved Aerated Concrete) panel
- All kinds of ceramic & vitrified tiles of all sizes including metal and wood tiles
- Natural stones sensitive to moisture, stone veneer, slate stone, laminated stone, Corian
- Onyx stone & agglomerated re-engineered resin-based quartz stone
- Large-size slabs of tiles & stone bonded with fibreglass mesh on the back
- All types and sizes of ceramic & glass mosaic
- Slim Tiles slab in 3mm thickness or cut stone with minimal thickness
- Ensure surface is sound, clean and free from oil, grease and dust
- If surface is uneven by more than 15mm, first level using correct material
- Do not pre-wet the surface with water
- For larger areas, provide movement joints every 3 metres or per local standard
- On external facades: avoid direct sun exposure — let surface cool before application
- Follow concrete expansion joints and connection joints per standard
- Open mono pack and mix full quantity of Part A hardener into Part B thick paste
- Use a slow-speed electric stirrer until homogeneous — manual mixing may compromise performance
- For part quantities: strictly maintain Part A:Part B ratio of 1:10
- Use a measurement jar to ensure correct ratio — incorrect ratio compromises performance
- Use mixed material within the pot life period
- Spread adhesive to desired thickness using Wallnut notch trowel
- Fix tiles or stone onto adhesive before skin formation — press firmly
- For large format tiles or stone: also apply adhesive layer on the back (back-buttering)
- For spot bonding: ensure minimum 25% tile surface coverage with adhesive
- Leave space between tiles for proper grouting and surface movement accommodation
- Leave 24 hours to bond — then grout with Wallnut Connect & Lock Epoxy Grout
Ideal working temperature: 10°C to 35°C. Avoid applying in direct sunlight or on very hot surfaces on external facades.
Work within the specified pot life after mixing. Extended open time (EN T class) gives you more working time vs standard adhesives.
Use the correct notch trowel for your tile size. For large format tiles (>600mm), use a 10mm or 12mm square notch trowel.
Full cure at 28 days at 23°C / 50% humidity. Light foot traffic after 24 hours. Do not grout before full initial cure.
Always mix Part A and Part B at the correct 1:10 ratio using a measurement jar. Incorrect mixing ratio will compromise adhesive performance and bond strength.
