Ronafix - a new image but the same quality, strength and performance

Ronafix has long been established in the construction industry as a quality polymer admixture; its reliability, performance and consistency making it a firm favourite with clients, specifiers, contractors and distributors.


Ronafix is the worldwide number one product specified for major and minor projects throughout the world and has full BBA certification.


One thing that has changed about Ronafix is the appearance of the five litre bottle. As part of a product rebrand, Ronafix five litre is now contained in a black bottle made from recycled plastic. Each of the three applications has a different colour label; orange and black for screeds, aqua blue and black for waterproofing and a vibrant red and black for bonding and bedding.


“We knew that Ronafix is a product renowned for its quality for over forty years, but that wasn’t reflected in the packaging. People new to the industry could have dismissed it as “just another admixture” if they weren’t aware of the Ronafix history and reputation.”


The new branding makes the bottle stand-out amongst other similar products and the metallic effect makes the labels shine, reflecting the quality of the, four times BBA accredited, admixture they describe.” - Daniel Osen, Managing Director
