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 weathertight membrane 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 acrylic weathertight membrane becoming New Zealand’s largest-selling waterproofing membrane product for claddings.

X-200 is made using a unique microfibre formulation, similar to the chopped glass fibres used in fibreglass. Like fibreglass they reinforce the coating and help with crack and void filling.

As part of a broader product review programme, it recently underwent its first true 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 weathertight membrane is suitable for use on masonry, blockwork and concrete surfaces, as well as plastered and rendered surfaces.
