Questions about the company

When was ERFURT & SOHN founded?

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.

When was woodchip first produced?

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.

How did ERFURT get its name?

The company is currently in the 7th generation of ownership by the Erfurt family.

Does Erfurt have an outlet store?

Unfortunately, we do not have an outlet store in Wuppertal.

Questions about the products

What are ERFURT wallpapers made of?

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.

What is the difference between KlimaTec thermal nonwoven and KlimaTec Pro KV 600 ?

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.

What can KlimaTec thermal nonwoven / KlimaTec Pro KV 600 do?

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.

How should I cover KlimaTec thermal nonwoven / KlimaTec Pro KV 600?

The energy-saving wall covering can be papered over with all conventional wall coverings, such as ERFURT woodchip.

What is the difference between Variovlies and Trendvlies?

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.

What is the difference between Novaboss Pro and foam wallpaper?

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.

What is the difference between Rauhfaser and Vlies-Rauhfaser?

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.

How can I wallpaper an archway?

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.

What is a pattern repeat?

The pattern repeat indicates when a pattern repeats itself on the wallpaper. You need to take the pattern repeat into account when calculating the number of rolls you will need if the wallpaper gives a pattern repeat on its label. As a rule, you will need to buy approx. 1 to 2 rolls more for a room as you will only be able to cut 3 rather than 4 lengths from a standard Euro roll (10.05 m × 0.53 m).

What is the paste-the-wall technique?

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.

What causes bubbles, and how can they be avoided?

Bubbles can appear for varying reasons:

1. Base surface

  • 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. 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.

2. Soaking

  • 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.

3. Paste

  • 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).

Which wallpapers must be painted?

All white wallpapers and Rauhfaser must be painted. We recommend dispersion paints marked 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.

Which ERFURT wallpapers may be used in rooms with high moisture?

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.

Which types of paints are most appropriate for use?

We recommend dispersion paints marked EN 13300. Satin and/or high-gloss paints are most suitable, as they accentuate the texture better than matt paint.

What are silicate paints?

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.

What are emulsion paints?

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.”

What are the differences between different interior dispersion paints?

Interior dispersion paints are differentiated by their washability (Class 2: scrubbable, Class 3: washable.)

Is it possible to wallpaper over styrofoam?

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.

Is it advisable to paste over old wallpapers?

Old wallpaper must be thoroughly removed. If it is not removed, the paste may loosen the wallpaper underneath, which may create bubbles.

When must the various base surfaces be primed? And with what?

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.
