Admix +
F.i. Admix + liquid polymer admixture is designed to enhance the performance of cement-based tile adhesives, mortars, grouts, renders, and levelling compounds. When used in place of water, this additive improves flexibility, adhesion, strength, and water resistance of cementitious systems. It is suitable for internal and external applications where improved durability and performance is required.

Application
| Tile adhesives | Use 1.1 litres of Admix + in place of 1 litre of water. |
|---|---|
| Cement slurries | Prepare 10 litres of Admix + with 20 kg of general purpose cement. |
| Screeds · bagged | Approximately 2–2.2 litres of Admix + per 20 kg bag. |
| Screeds · site blend | 1 part Admix + : 1 part GP cement : 3–4 parts sand, by volume. |
| Renders · bagged | Approximately 2.5–3 litres of Admix + per 20 kg bag. |
| Renders · site blend | 1.5 parts Admix + : 1 part GP cement : 3–5 parts sand, by volume. |
| Storage | Store in original unopened containers. Protect from heat and frost. |
Limitations
