Leading Swedish manufacturer of

thermosetti​ng resin floor coatings​

What is seamless flooring?

​A seamless floor is a coating made of thermosetting or thermoplastic resin. Eradur AB delivers liquid flooring where component A + B is mixed by the flooring contractor on-site for installation and application to the substrate. After application, the product cures to a hard and very durable floor without joints. Usually, several layers of different products are combined to create a finished floor system. Seamless floor coatings are often referred to by other names such as compound- resin- acrylic- and epoxy flooring.

Curing resin coatings become very robust thanks to the strong chemical network: "polymer" that is formed during the curing process. A seamless resin coating has good temperature resistance, very good mechanical durability and is well resistant to chemicals. The thermosets used for seamless floors can be chemically divided into three different classes, depending on their chemical composition:

Epoxy, polyurethane, and acrylate. The chemical composition affects the properties, both during installation and on the finished product.

Annually, approximately one million square meters of seamless resin flooring is laid in Sweden and the products have been on the market for over 50 years.

​What are the advantages of seamless flooring?

What distinguishes a seamless floor is that it is applied as a liquid mass and thereby forms a homogeneous surface without joints and cures to a very strong polymer. These factors provide a hygienic, easy to clean and extremely durable surface against both chemical and physical effects. A seamless floor can also be made self-levelling, which gives a smooth surface even on slightly uneven surfaces. The application of a seamless coating takes place quickly, and the floor is ready to use after only a few days.

Most substrates can be coated after a proper pre-treatment. Old or new surfaces; concrete, levelling compounds, metals, wood and board products, asphalt and more. The conditions may differ but it is solved with the right pretreatment.

Through access to different chemistry, the coatings can be adapted to a variety of environments with specific requirements for function and aesthetics. 

For example:

  • Impact and abrasion resistant floors

  • Floors that withstand high point loads

  • Flexible flooring for substrates with moderate movement

  • Easy to clean floors for businesses with high hygiene requirements

  • Floor with built-in slipcover

  • Floors that withstand harsh chemicals such as acids, bases, and solvents

  • Electrically conductive floors for countering static electricity

Installing seamless flooring

​A trained floor contractor has the experience and machinery needed to create a safe work environment and a floor with expected function and service life.

Installing seamless floors is normally done in three parts:

  1. Preparatory work

  2. Priming

  3. Laying of the floor mass

The preparatory work includes repair of any damages in the concrete by using epoxy grout or a special cement filler. Additionally, the substrate should be sandblasted or diamond ground. Especially in heavy and tough industrial environments, the substrate must be properly processed so that the thermosetting plastic can penetrates the substrate and achieves an adequate attachment. When the preliminary work is complete, the priming takes place which aims to provide improved adhesion. Subsequently, the liquid floor mass and in some cases also the topcoat can be applied. Normally, the floor can be operational the day after laying and curing. In the case of special surfaces, such as acid-resistant floors, the thermosetting resin should be allowed to cure for an extended period of time. This is done to let the chemical resistance reach the maximum level before the floor is put use. Depending on the circumstances, it may take between two and five days.
