Find answers to the most recurring questions based on ADFORS expertise and experience

What tools are needed for the application?

  • Brush or roller to apply the glue.
  • Tape measure.
  • Marker pen.
  • Spirit level.
  • Knife for cutting or scissors.
  • Plastic spatula or rubber roller to press the product to the wall.
  • Longer steel spatula for trimming (corners, ceiling, floor).
  • Tools for painting.

What should the wall look like before starting the application?

  • The wall should be clean, dry and without any dirt.
  • The wall quality should be Q3 or better.
  • In general, it should be as flat as possible.

How is the wall primed?

  • Use a primer suitable for your particular wall type.
  • You can use ADFORS ready-to-use glue mixed with clean, cold water – using a ratio of 1:1.

What kind of glue should I use?

  • Ready-to-use glue for glass fiber wallcoverings or a standard glue for wallcoverings – e.g. ADFORS glue, Metylan Ovalit.
  • To get the best results use ready-mixed glue, not powder ones. Even if the latter are cheaper, it's more demanding to prepare the right mix and they provide less adhesion.

How much glue should be used?

  • About 250g per m2 of glue should be used, and you should be able to draw in the glue layer using your finger.
  • It is important is to spread the glue evenly and the layer should be uniform.
  • It is better to have too much glue than too little.

How is any excess glue removed?

  • Remove it immediately after application with a wet towel or sponge.
  • Do not let it dry as it will change the glossiness of the surface.

Humid environments

  • There is no issue installing fiberglass wallcoverings in humid environments, just use the proper glue recommended for these conditions.
  • Fiberglass wallcoverings should not come into direct contact with water (e.g. from a shower) unless this is something specifically designed within the system.

How are joints made?

  • All ADFORS wallcoverings are carefully edge-cut and are designed to be applied edge to edge.
  • Pay close attention to the edges of the roll as any damage to these will make the joint visible.
  • In the case of non-wovens (vlies), you can perform a double-cut to make joints invisible.

How is it applied around corners?

  • Its specifically designed coating means the product is easy to fold or bend around the inside or outside corners.
  • At least 20cm of material should be left over the corner on each side to ensure proper adhesion.

Health issues

Glass fiber used for production of fiberglass wallcoverings is not harmful to health – this is proven by the World Health Organization (WHO). Fibres need to have a much lower diameter in order to be carcinogenic – we use around 10 microns (μm), the WHO threshold is 3 microns (μm).
