Key Features

What Makes Smart Plus
Stand Out

The first adhesive in its class with improved tensile adhesion beyond C1 requirements — plus lightweight, eco-friendly formulation for green buildings.

C1 TE · Exceeds Class 1 High Polymer Interior Exterior Low VOC
01
🏆
Exceeds Class 1 Strength

First in class 1 category with improved tensile adhesion ≥ 1.0 N/mm² — exceeds EN C1 TE standard requirements.

02
🌿
Eco-Friendly Formula

Very low VOC, recycled raw material, 100% recyclable after expiry — suitable for all types of green and certified buildings.

03
⚖️
Lightweight

Light weight formulation reduces structural load — ideal for wall applications, especially on upper floors and facades.

04
⏱️
Extended Open & Adjustability Time

≥ 30 minutes open time and > 30 minutes adjustability — allows repositioning of large format tiles without rush.

05
🔲
Full Thixotropic

Fully thixotropic formula ensures zero slippage on walls — ideal for large format wall tiles in bathroom and lobby areas.

06
📐
High Coverage

~60 sq ft per 20 kg bag at 3mm thickness. Minimum 3mm, maximum 10mm — high coverage with minimum material.

07
🚿
No Water Curing

No water curing required after tile fixing — saves time, water and effort on site. Single component, just add water.

08
🧱
Large Format Wall Tiles

Absorbent porcelain tiles of big size on walls can be fixed with ease in areas such as bathrooms, lobbies and facades.

💪
High Grip Technology

Proprietary High Grip formulation ensures maximum initial tack and prevents tile slippage on walls — even with large format tiles under gravity load.

🧬
Polymer Modified

High polymer modification significantly improves tensile adhesion, flexibility and durability over standard OPC-based mortars — exceeds EN C1 TE class requirements.

Important Limitations

Product Not to Be Used

Smart Plus is engineered for absorbent surfaces. For the following applications, use the recommended Wallnut alternative.

🚫
Non-Absorbent Concrete Use Calcibond Secure for dense, non-absorbent concrete surfaces.
🚫
Metal, Wood, Rubber & Cement Board Use Calcibond Ultima for these non-cementitious substrates.
🚫
Moisture-Sensitive Stone Use Calcibond Ultima for stones sensitive to moisture or water absorption.
🚫
Soft or Brittle Stone Use Calcibond Advance or Ultima for stone that is soft or brittle in nature.
🚫
Recomposed Stone Use Calcibond Advance or Ultima for engineered and recomposed stone products.
🚫
Expansion Joints & Extreme Movement Do not apply over expansion joints or in areas with extreme structural movement.

Application Guide

How to Use Smart Plus

01
Suitable Surfaces
+
  • Fully dry and sound new or old traditional plaster (cement sand render)
  • New or old absorbent IPS or PCC floors which are sound and stable
  • Absorbent concrete surfaces
  • Traditional cement:sand screed or screed made with Zeorich Base or similar
02
Suitable Tiles
+
  • All types of absorbent ceramic & porcelain tiles
  • Vitrified tiles (GVT / PGVT) — interior use
  • Stable natural marble in interior floors
  • Large format absorbent tiles on walls
  • Ceramic mosaic tiles
03
Surface Preparation
+
  • Ensure plaster/screed is sound, clean and free from oil, grease and dust
  • If surface is uneven >10mm, level first with correct levelling material
  • Alternatively, apply a thin coat of Smart Plus and wait 24 hours before tiling
  • Splash clean water onto dry surface and let it surface-dry to improve workability
  • In external environments, cool the surface before applying — hot surfaces compromise performance
  • For large areas, provide movement joints every 3 metres or as per local standard
04
Mixing
+
  • Grey bag: add approx. 5.25 litres of clean water per 20 kg bag
  • White bag: add approx. 5.5 litres of clean water per 20 kg bag
  • Use a slow-speed electric stirrer — manual mixing compromises performance
  • Adjust water quantity as per ambient temperature and surface dryness
  • Final mix must be a uniform, workable paste
  • Do not add extra water once mixed — use within pot life (>2 hours)
05
Application
+
  • Spread adhesive 3–10mm thick onto cement surface using appropriate notch trowel (6×6mm or 10×10mm)
  • Fix tiles before skin formation — press firmly with a twisting motion
  • For large format tiles, also apply adhesive to back of tile (buttering)
  • Leave uniform joints between tiles for grouting and movement accommodation
  • Allow 24 hours before grouting — use C&L Lite Grout or C&L Epoxy Grout
  • Walking on floor: after 24 hours. Normal use of surface: after 2 weeks
⚙️ Application Tips
🌡️
Temperature

Ideal working range +5°C to +35°C. Above 35°C, avoid use under direct sun. Below 5°C, initial and final setting times will be affected.

⏱️
Pot Life & Open Time

Pot life is >2 hours after mixing. Open time is ≥30 minutes — take advantage of extended adjustability for large format tile work.

📐
Trowel Selection

Use 6×6mm notch trowel for small tiles; 10×10mm for large format tiles. Always match trowel to tile size for correct bed thickness.

🚀
Setting Timeline

Initial set: 6–8 hrs. Final set: 24 hrs. Full strength at 28 days. Final resistance –30°C to +80°C after 28 days cure.

⚠️

Once bags are open, entire material must be consumed within 24 hours. Do not use over expansion joints. Ensure surface is not contaminated before application.
