Product Description
Ronafix Universal is a versatile polymer liquid additive used to improve the performance of cementitious screeds, renders and concrete repairs. When used as a partial or full replacement for mixing water, it enhances adhesion, flexibility, water resistance and durability of the finished mix. Supplied in 25-litre containers.
Key Benefits
Application
Use as a partial or full replacement for mixing water according to the required application. For general-purpose improvement, dilute 1 part Ronafix to 3 parts water. For maximum performance (bonding coats, waterproof renders), use undiluted. Add the required amount of liquid to the mixer, then gradually add cement and aggregate while mixing. Apply at temperatures between +5°C and +30°C.
Coverage
Dosage varies by application — typically 1–5 litres per 25 kg of cement depending on dilution ratio and required performance. One 25-litre container treats approximately 5–25 bags of cement.
