"Eco Choice Aotearoa is thrilled to award its ecolabel to Critical; a business committed to innovation, transparency, people and planet.

During the certification process, most first-time applicants find they need to reconsider their usage of particular ingredients, materials or production methods. However, Rui and his team were fully prepared and worked diligently through our strict pass/ fail criteria. Our ecolabel is earned, not bought, and Critical has absolutely earned it – whakamihi!”

Working with Cleanstone

Cleanstone is a new product and must be treated as such. While it is similar to working with materials like plastic sheeting it has characteristics that differ from other products, presenting challenges that may differ from what you would automatically assume from a product such as plywood, laminate or engineered stone. Considerations for example are it's current thickness variation, product weight, differences in dimensional stability as well as unique requirements when cutting, finishing and joining, etc. For these reasons we highly recommend you refer to our Cleanstone manual before installation.

Like all materials if handled incorrectly it is possible to waste both time and material. Understanding this document is crucial to avoiding this. If this is your first time working with Cleanstone and you are unsure about how to work with it, please download our manual below and reach out to one of our technical experts. We're here to help.
