Pre-treatment of old walls

​

The materials used to build old houses are quite poor quality or simply outdated. It is often not generally known what the walls are made of. Their surface is very insidious as yellow spots can appear on it due to rusty pipes, poor quality wiring and other faults caused by decades of use by builders. When installing liquid wallpaper to avoid discoloration, carefully protect the walls. First, you need to treat the entire surface with impregnation or Silk Plaster primer. To achieve the ideal result, we recommend over-leveling the walls before applying the primer.
