The present invention provides a method for applying a surface coating on, for example, a sheet of fabric and further provides a plasma chamber (10) for coating a sheet of fabric, e.g. a textile material, with a polymer layer, the plasma chamber (10) comprising a plurality of electrode layers (RF, M) arranged successively within the plasma chamber, wherein at least two adjacent electrode layers are radiofrequency electrode layers (RF) or ground electrode layers (M), thereby providing a surface coating on both sides of a fabric sheet.
