Calcibond Ultima

Calcibond Ultima is a unique eco-friendly, very high flexible two-part POLYURETHANE ADHESIVE — with elongation of 30mm for the most demanding installations.

01 Suitable Surfaces + - 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 02 Suitable Covering Materials + - 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 03 Surface Preparation + - 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 04 Mixing Instructions + - 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 05 Application + - 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

🌡️ Temperature Ideal working temperature: 10°C to 35°C. Avoid applying in direct sunlight or on very hot surfaces on external facades. ⏱️ Open Time Work within the specified pot life after mixing. Extended open time (EN T class) gives you more working time vs standard adhesives. 📐 Notch Trowel Size Use the correct notch trowel for your tile size. For large format tiles (>600mm), use a 10mm or 12mm square notch trowel. 💦 Cure Time 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.
