DG27
DG27 is a primer/pretreatment for substrates containing gypsum based plasters e.g. plasterboard. It prepares the gypsum based surface by sealing the gypsum away from the lime mortar and provides a mechanical key to improve adhesion. The primer is compatible with lime mortar as it regulates absorbancy, does not form a film remaining easily permeable by water vapour.
