For the creation of coloured acoustic surfaces, the BASWA coating masses are custom-dyed at the plant as ordered. The BASWA acoustic AG lab determines the colour recipes from scratch for each new colour. Given the specific properties of porous surfaces, each colour recipe is visually compared with the original sample. The pigmenting products are mixed into the coating masses; no further additives are used. Subsequently, the dyed coating masses are processed at the construction site. BASWA coating masses can be custom dyed in almost all hues available.
