For new walls: Apply one coat of Jotashield Penetrating Primer or Jotashield Resistant Primer. Then apply two coats of Jotashield ColourXtreme Matt or Silk. In case the plaster is not uniform on your wall, we advise you to use one coat of Jotashield Filler after the primer to ensure a pleasing end result. In addition to that, Jotashield Extreme can be used on top of any of the textures to change the colour and increase durability, as well as reduce temperature.
