Tile Bond (Cementitious Tile Adhesive) Recipe
Polymer-modified cement tile adhesive similar to EN 12004 class C1/C2, for floor and wall tiles on cement backgrounds. Use a branded product where specified; this is a site/plant reference formula.
Reference standards: EN 12004, ANSI A118.4
| Ingredient | % by weight of powder | Role |
|---|---|---|
| OPC (Grade 42.5) | 35–40% | Binder |
| Silica sand 0.1–0.5 mm | 56–62% | Filler, dried |
| Redispersible polymer powder (VAE) | 1.5–3% | Bond & flexibility (C2 ≥ 3%) |
| Cellulose ether (HPMC) | 0.3–0.4% | Water retention, open time |
| Calcium formate | 0.5% | Optional accelerator |
| Mixing water | 22–26% of powder | ≈ 5.5–6.5 L per 25 kg bag |
Mixing & application
- Dry-blend powders thoroughly in a mixer; bag in moisture-proof bags.
- On site add powder to clean water, mix with a paddle at low speed for 3–5 minutes.
- Let it slake 5 minutes, remix briefly; use within 2–3 hours.
- Apply with a notched trowel (6–10 mm notch) on a clean, damp substrate.
- Press tiles with a twisting motion within 20 minutes of open time; keep joints with spacers.
- Grout after 24 hours.
Acceptance criteria
- Coverage ≥ 80% (walls) / 95% (wet & floor areas) when a tile is lifted.
- Tensile adhesion ≥ 0.5 MPa (C1) or ≥ 1.0 MPa (C2).
Health & safety
- Wear PPE: helmet, safety shoes, gloves and eye protection.
- Avoid inhaling powder.
