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.\u003c\/p\u003e\n\u003ch3\u003eCoverage\u003c\/h3\u003e\n\u003cp\u003eDosage 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.\u003c\/p\u003e","brand":"RONACRETE","offers":[{"title":"Default Title","offer_id":51124649099603,"sku":"RONA-25L-25L","price":182.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/6720\/9043\/files\/Screenshot2026-01-14at13.14.24.png?v=1768392882","url":"https:\/\/shop.screedworks.co.uk\/products\/ronafix-universal-25l","provider":"screedworks","version":"1.0","type":"link"}
