Tile Adhesive Classifications .. S1, S2, C2FT, C2TE and more.. Leave a comment
We are frequently asked about the classifications of tile adhesives, so we thought we’d put together a summary of all the common ones in the table below. The British Standards BS EN 12004:2007 governs the classifications.
In accordance with this standard, tile adhesives are determined by a combination of three factors: the adhesive’s chemistry (dispersion, cementitious, reactive resin), its level of performance (normal or improved), and any other optional features ( rapid setting, reduced slip etc).
| Classification | Optional Characteristics |
|---|---|
| D = DISPERSION 1 = NORMAL DISPERSION 2 = IMPROVED DISPERSION | F = FAST SETTING ADHESIVE T = REDUCED SLIP |
| C = CEMENTITIOUS 1 = NORMAL CEMENTITIOUS 2 = IMPROVED CEMENTITIOUS | E = ADHESIVE WITH EXTENDED OPEN TIME S = ADHESIVE WITH DEFORMABILITY |
| R = REACTIVE 1 = NORMAL REACTIVE RESIN 2 = IMPROVED REACTIVE RESIN | S1 = DEFORMATION > 2.5mm BUT < 5mm S2 = DEFORMATION >5mm |
These can be then further expanded into the following:
| Type | Class | Description |
|---|---|---|
| C | 1 | NORMALCEMENTITIOUS ADHESIVE |
| C | 1F | NORMALFASTSETTING CEMENTITIOUS ADHESIVE |
| C | 1T | NORMAL CEMENTITIOUS ADHESIVE WITH REDUCED SLIP |
