Ndurance is a strong, tough and sturdy liquid applied floorcovering made with vegetable oil, pigments and post-consumer recycled content. Ndurance contains no plasticizers and stays flexible overtime.

On site Ndurance is poured on the subfloor, where it sets overnight to create a seamless, durable resilient floorcovering with excellent properties. A perfect floorcovering without cutting losses, without welded seams and therefore perfectly suited for schools, offices and medical facilities.

Ndurance is RED LIST FREE and LEED and BREEAM certified.

Duracryl produces floorcoverings based on natural and renewable materials. This has a major advantage on climate change compared with fossil based products.

For accountability of the impact of the carbon footprint of each flooring product we are using the definition of “Healthy Materials Lab at Parsons School of Design” in New York, a leading authority on this subject.

“Currently, there is no universal threshold for ‘low embodied carbon’ in flooringmaterials. After discussing this research with experts, we have set a rigorous standard that can meet 2030 emission goals. These products, labeled with ‘LEC’, embody below 5kg of CO2 per square meter”

All Duracryl products comply with this standard and are referred to as “Climate Positive Flooring”

composition

cure through

Ndurance is walkable 24 hours after the installation. The complete chemical and mechanical properties will be achieved after 7 days of curing at a minimum temperature of 15°C.

maintenance

Regular removal of dust and if necessary wet cleaning with a neutral cleaning agent. For further instructions see the maintenance instruction guide.

installation

The concrete or screed subfloor has to be primed and levelled with a self levelling smoothing compound to obtain a flat and levelled surface. Uneven surfaces have to be leveled by e.g. diamond grinding prior to the levelling compound. All dust and loose parts have to be fully removed from all surfaces before the product is applied, preferably using a brush and/or industrial vacuum cleaner. Prior to the installation of the Ndurance a suitable primer needs to be applied. During the installation the room temperature needs to be at least 62 °F (15,5°C). The floor temperature need to be at least 59 °F (15°C) and minimum 3 °F (3 °C) above the dew point.
