Understanding Adhesive Classifications
Tile adhesives in Australia are classified under AS ISO 13007. Knowing the codes helps you pick the right product:
- C1 — Standard cement-based adhesive. Interior floor and wall tiling on stable substrates.
- C2 — Improved bond strength. Required for exterior, large-format, porcelain, and commercial.
- S1 — Deformable (flexible). For heated floors, timber substrates, and tiles over 600mm.
- S2 — Highly deformable. Swimming pools, facades, and substrates with significant movement.
- T — Thixotropic (non-slip). Resists sag on vertical surfaces — essential for walls.
- E — Extended open time. Longer working time before the adhesive skins over.
- F — Fast setting. Grout the same day — ideal for commercial turnarounds.
Popular Products
| Product | Best For |
|---|---|
| Ardex X17 | The go-to for most residential and light commercial tiling — walls and floors, internal and external. Cost-effective polymer modified adhesive with extended open time. Choose X17 when you don't need swimming pool or fibre-reinforced performance. |
| Ardex X18 | Premium all-rounder with fibre reinforcement and S1 flexibility. Everything X17 does plus swimming pools (with E90 additive for S2), large-format tiles, and demanding commercial work. |

| Ardex Optima | Two-part adhesive for difficult substrates — tile over existing tiles, steel, fibreglass, or particleboard without grinding. S2 classified and pool rated. |
| Laticrete 254 Platinum | High tack, extended open time, rated for pools, steam rooms, radiant heat, and tile-over-tile. A strong alternative for tradies who prefer the Laticrete system. |

Common Questions
White or grey adhesive? — White is mandatory under natural stone, marble, and any translucent or light-coloured tile. Grey is fine under standard ceramic and darker porcelain. When in doubt, go white.
Can I use any adhesive for a swimming pool? — No. Pools require adhesives rated for permanent immersion under AS 3958.1, such as Ardex X18 with E90 or Laticrete 335 Premium.
Should I use Ardex X17 or X18? — X17 for standard residential work on concrete or cement sheet. Step up to X18 for pools, timber subfloors, large-format tiles, or commercial jobs.
Do I need to back-butter large tiles? — Yes. For tiles over 600 x 600mm, apply adhesive to both the substrate and the tile back for full coverage.
What trowel size should I use? — 6mm for mosaics, 10–12mm for standard tiles, 15mm+ for large-format. Larger notches give better coverage and bond.
