Corques

liquid lino

Corques is a linoleum, based on natural materials. Linseed oil, vegetable oil, cork and mineral fillers seamlessly applied.

Corques is a tough, flexible seamless comfortable floor covering. Corques can be used as a seamless decorative floor covering in the education sector, medical sector, offices, museums, but is also suitable for domestic surfaces. In short Corques is a perfect solution for floors where the owners and users have a high demand on comfort, wear and impact resistance and hygiene. Corques is a seamless solution from wall to wall.

Carbon footprint

KG/m2

With its lasting resilient properties and natural appearance, Corques Liquid Lino stands out from many other floors. The product composition consists of a balanced mix of mainly natural raw materials such as vegetable and linseed oil, wood and cork powder and limestone cork.
Other plus points of the Corques Liquid Lino floor are that it is wear-resistant and, with a layer thickness of about 2 mm, it has very good thermal conductivity which improves efficiency with underfloor heating. The floor is seamless as it is a cast system. This means no welds, job plan and cutting losses as with other floor coverings. Moreover, Corques Liquid Lino is available in many colours.

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

Corques is a linoleum, build from vegetable oil, linseed oil, wood and cork powder, limestone cork and other pigments. Corques is a liquid applied floorcovering which results in a seamless lino floor.

application

appearance

Corques has a mingled appearance with a smooth level surface. Due to the natural character of Corques are slight color variations in the appearance possible. Corques has a matt finish. Corques comes in a wide variety of standard colors, custom design colors to suit your special design requirements are also possible.

PROPERTIES

Corques is wear resistant and shows high mechanical properties. Corques is tough-elastic and shows a perfect resistance to the signs of use. After cure through Corques is resistant to a wide range of chemicals, acids, leys, resins, solvents and foodstuff. Corques is seamless and liquid tight. The majority of the ingredients in Corques are renewable resources. Corques is free of plasticizers. Corques is easy maintainable. After many years of intensive use Corques can be re topped at a fraction of the initial costs.

cure through

Corques 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.

environmental aspects

Corques is made with renewable resources and is free of the Red List ingredients. Corques is made with renewable resources and has a Declare RedListFree label. No hazardous materials are used. Because of the natural ingredients it has a positive climate impact. Corques does not contain hazardousn decomposition products.

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 Corques 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. The application is very labor friendly since it comes in 33 lbs (15KG) buckets. No welding, no cutting losses, no adhesives.

Fredrick walton
collection

Frederick Walton (1834 – 1928) was an English pioneer and researcher.
In 1857 he discovered a method using vegetable oil
to produce a floorcovering.

This discovery lead to his most famous invention: Linoleum. This was the start of a long and fruitful Linoleum era. To this day his entrepeneurship is beyond any doubt a milestone in the history of flooring. To honour his unique efforts, Duracryl is proud to present a special collection named after him.
