Do you have a surface with too high or irregular absorbency to apply your plaster plaster directly? Then use Knauf's Stuc primer! This primer is ideal for reducing the absorbent capacity of the surface without clogging the pores.

The primer is suitable for building elements made of aerated concrete or sand-lime brick and old masonry, and prevents the plaster from burning. It is only used indoors, in combination with plaster plasters.
