Resene X-200: Time-tested waterproofing system
04 Sep 2026
You don’t become the number one brand anything without having an in-depth knowledge of your market and your product. After 80 years of colour and product innovation, it’s not surprising that Resene holds that spot in the New Zealand marketplace.
A reputation for constantly innovating and ongoing development has resulted in a stable of products that truly spans the gamut of architectural projects.
First released in the mid-80s, Resene X-200 waterproofing system was the first fully acrylic waterproofing system in New Zealand. What made it revolutionary at the time was that it removed the need for the multicoat combinations of bituminous basecoats and water-based topcoats that was the industry standard at the time – it was common for upwards of seven or more layers to be specified to waterproof masonry.
Another revolutionary feature was that it came with a 10-year waterproofing guarantee, which has never been successfully challenged, and which has contributed to X-200 waterproofing system becoming New Zealand’s largest-selling waterproofing membrane product for claddings.
X-200 incorporates a unique microfibre, similar to the chopped glass fibres used in fibreglass. Like fibreglass, these microfibres reinforce the coating and help with crack and void filling.
As part of a broader product review programme, it recently underwent its first major upgrade – former modifications were designed to broaden its colour range including incorporating CoolColour technology – with the addition of a polyurethane component to improve durability and flexibility.
Resene X-200 waterproofing system is suitable for use on masonry, blockwork and concrete surfaces, as well as plastered and rendered surfaces. X-200 features on many of New Zealand’s most significant multilevel projects as well as housing and is a key element of the Rockcote Cladding systems.
