On June 16, 1827, Friedrich Erfurt (1768-1837), paper-maker by trade, received government approval to open “Papierfabrik Friedrich Erfurt & Sohn” in Dahlhausen near Schwelm.
The paper factory, Erfurt & Sohn KG, was founded in 1827. In 1864, Hugo Erfurt, grandson of the company’s founder, developed a new product called Rauhfaser. The material was first used as a decorative paper for display windows and as a base paper for collotype wallpapers. In the 1920s, its advantages in at-home décor were discovered. Painted in individual colours, it was possible to achieve unique effects in each room. Unique effects can be created in a room by painting the wallpaper in different colours.
ERFURT products contain only paper fibres, textile fibres, wood pulp, and wood dust, as well as auxiliary materials. To this end they have been issued a Certificate of Conformity in all areas from the ISEGA (Research and Testing Institute in Aschaffenburg, Germany.) Our wallpapers do not contain PVC, toxic softeners, or glass fibres.
KlimaTec thermal nonwoven and KlimaTec Pro KV 600 are smooth energy-saving interior wall coverings that are produced as a 2-component composite product from special textile fibres. The difference between the two products is down to the quicker heating up of the air in the room due to the different thicknesses of the material.
KlimaTec thermal nonwoven measures 10 m × 0.75 m and is sold in DIY and hardware stores, building outlets and home improvement stores. KlimaTec Pro KV 600 measures 15 m x 1.00 m and is sold through specialist trade wholesalers.
Using KlimaTec thermal nonwoven / KlimaTec Pro KV 600 you will have warm walls and a cosy feeling in your room just short time after you have switched on the heating - no more cold walls. You will be primarily heating the air in the room and not the walls, thereby saving a significant amount of energy when heating rooms intermittently.
The energy-saving wall covering can be papered over with all conventional wall coverings, such as ERFURT woodchip.
Variovlies and Trendvlies are smooth, crack-resistant, dimension-holding materials, which are made of wood pulp and textile fibres.
Variovlies weighs 160g per square metre, measures 25m long x 0.75m wide and is available in professional stores. Trendvlies weighs 140g per square metre, measures 20 m long x 0.75 m wide and is available in do-it-yourself/home improvement stores.
The main difference between the two is in the material. Novaboss Pro is a three-layer embossed wallpaper. It is a good alternative to foam wallpapers, because they contain PVC and are not as resistant to abrasion. Foam wallpapers are based on a PVC film laminated with a paper or fleece layer.
Rauhfaser contains recycled paper and wood pulp (high-quality paper fibres.) The wood fibres, which create the texture, are made out of solid fir tree wood (from well-managed forests in Germany.) In the production of Vlies-Rauhfaser, textile fibres are also added. These additives give Rauhvlies its stability in dimension and its tear-resistance.

KG certifies that ERFURT-Profi Rauhfaser styles 20, 32, 40, 52, 70, 79, 80, 1000 and the ERFURT-DIY woodchip styles: Elegance, Romantic, Classico, Avant-garde, Rustic, Country and Sprint are produced using materials that have been inspected against allergens and contaminants. The test includes microbiological, chemical and emission examinations to test the above requirements.
Woodchip is an ideal solution even for "sensitive" target groups, like allergy-sufferers.
ÖKO-Test “Very good“
Issue: Kompakt, Wohnen & Garten Nr. 06
The ÖKO-Test Publishing House GmbH in Frankfurt a.M. gives Rauhfaser 52/Classico a final rating of “Very good.” The total rating is based on an assessment of content (price, composition, and presence of contaminants) and in-home product sampling (tear strength when wet, processing, opacity and opacity after the first coat of paint.)
The Öko-Test seal stands for trustworthiness, and awards Rauhfaser its seal of approval.
The environmental seal is awarded through the RAL e.V. and is valid for wallpapers made from base paper according to DIN 6730:2003 and for ingrain woodchip according to DIN 6730:2003. This entails the fulfilment of requirements of the production of products made predominantly out of recycled paper and for the ecologically friendly, low emission production of awarded product.
ERFURT, both as a company and trademark, embodies environmental responsibility.
“ERFURT - Proven safety: Just for you” is a small demonstration of our internal quality assurance efforts, and our obligation to have these continually verified by third parties.
First, hang the stretches of wallpaper beside and above the archway with ca. 2-3 cm overlap. Then, cut several slits into the overlapping paper, fold over and adhere in the archway. Finally, adhere the cut-out soffit-strip into the soffit. It is recommended that when using heavier wall coverings or patterned papers, to use corner-molding that can be fit easily onto rounded surfaces.
The pattern repeat indicates when a pattern repeats. You need to take the pattern repeat into account when calculating the number of rolls if a wallcovering indicates a pattern repeat on its inlay. As a rule, about 1 to 2 more rolls are needed for a room, because only 3 instead of 4 lengths of wallcovering can be cut from a euro roll (10.05 m × 0.53 m).
When using the wall adhesive technique, paste is applied to the walls, and the dry strips of wallpaper may be laid onto the pasted wall and pressed onto the wall. This is only possible with wallpapers that that hold their dimensions, such as fleece wallpapers. This is not possible with paper wall coverings.
Bubbles can appear for varying reasons:
1. Base surface
- The base surface is too absorbent (ie. gypsum plaster board.) Since the paste may soak too quickly into the wall in places, the wallpaper on these places may loosen and create bubbles.
- Absorbency can be reduced by using a solvent-free primer.
- The base surface is clogged. This can occur when too much primer has been applied, which may be evidenced by a greasy appearance on the base surface following priming. Water can then bead on the walls. Since a closed layer has been formed on the wall, the paste cannot adhere to the wall. Therefore, this layer must sanded away using either sandpaper or a polisher.
- The base surface is too coarse.
- The base surface is not stable.
- It is necessary for paper wallcoverings to soak, because paper is made of wood fibres, which swell when in contact with moisture (paste.) This causes the wallpaper to become wider and longer. If the wallpaper is not allowed to soak for the recommended amount of time, the wallpaper will stretch when hung on the wall, which causes bubbles.
- Incorrect paste
- Paste is too thin, as a result of mixing too much water
- Layer of paste is applied too thinly
- Layer of paste is applied to thickly
- Additional paste applied to wall before hanging wallpaper strip (in the case of paper wallcoverings)
4. Other reasons
- High humidity, due to closed windows and doors
- Low temperatures (at temperatures lower 10 °C, the wallpaper dries too slowly).
All white wallpapers and Rauhfaser must be painted. We recommend dispersion paints marked DIN EN 13300. The best paints to use are satin-gloss and high-gloss paints, because they enhance the appearance of the textures better than do matte paints.
All ERFURT wallpapers may be used in any room of your home. In the bathroom, the water should not be allowed to spray onto the wallpaper (directly inside the shower) or the paste will loosen. Water splashed from the tiles or onto the ceiling will not loosen the wallpaper.
We recommend dispersion paints marked DIN EN 13300. Satin and/or high-gloss paints are most suitable, as they accentuate the texture better than matt paint.
Mineral paints - also called silicate paints, water glass paints (because of the binding agent used) or Keim paints (after the inventor) – are paints that, in addition to using inorganic dyes as binding agents, also use alkali-silicate water glass (also known as potassium water glass, liquid potassium silicate, or liquor silicon.) These paints are generally high quality, long-lasting and expensive. They are usually intended for professional use, and are therefore mostly found in specialty stores, and not in do-it-yourself/home improvement stores. These paints are divided into two categories: Pure silicate paints or two-component silicate paints – that must be stirred before using – and silicate dispersion paints – that, like synthetic resin dispersion paints, are usually available ready-to-use in a 10 liter, oval-shaped bucket.
Emulsion paints are viscous coatings that consist of a chemical dispersion (usually an emulsion) of adhesives and solvents; colorants (usually pigments) and other additives. In such a general sense, the majority of liquid paints would be categorized as dispersion paints. In layman’s terms: this includes most of the approx. 20 kg barrels with white paint in an oval-shaped 10 litre bucket, which can be found in any home improvement store. More specifically, these are synthetic resin dispersion paints. Also on the market are products with a similar composition. These are usually non-synthetic and do not include mineral oil, and are - somewhat vaguely – categorised as “natural dispersion paints.”
Interior dispersion paints are differentiated by their washability (Class 2: scrubbable, Class 3: washable.)
It is not possible to apply wallpaper directly onto styrofoam. Before application, a primer must be applied. Dilute styrofoam paste with 20% water, and then apply with a brush or a paint roller. Alternatively, a smooth piece of fleece wallpaper can be applied directly to the styrofoam base surface using Ovalit V adhesive.
Old wallpaper must be thoroughly removed. If it is not removed, the paste may loosen the wallpaper underneath, which may create bubbles.
New plaster board surfaces must be primed with a solvent-free primer; Wood materials with a solvent-based primer. For all other absorbent base surfaces, see table (PDF).
The base surface must still be absorbent following priming.

Generally, there is no limit to how often you can paint woodchip wallcoverings. It is really up to you whether the wallcovering can cope with another coat of paint or whether it would be better to replace it. The more often paint is applied, the less pronounced the texture of the woodchip will be. In essence, you could keep painting it until the woodchip more or less becomes “smooth”.
We have not yet been able to confirm the statement that the wallpaper could fall off the walls if it is painted too often.
However, ultimately the quality of the result depends on the paint and how it is applied. Satin gloss paints are thinner than matt paints. It depends on how thickly the paint is applied. In principle, it is better to apply two thinner coats than one thick coat. This gives a much more even finish. We attach great importance to being able to paint over our wallcoverings in the production of ERFURT wallcoverings.
