Overview
Thistle Durafinish is a gypsum finish plaster specially
formulated for increased resistance to accidental damage.
It enables significantly longer maintenance intervals and
lower long-term cost in heavy traffic areas of many types of
building.
It may be used on a wide range of backgrounds including
most undercoat plasters, and to enhance the surface
damage resistance of any British Gypsum partition or wall
lining system. It is particularly suited to the applications for
GypWall EXTREME and GypWall ROBUST.
Applications
Thistle Durafinish is designed for the finishing of a wide
range of backgrounds, from low-suction (e.g. plasterboards,
Glasroc MultiBoard, FireCase S and Rigidur, Thistle Dri-Coat,
sufficiently flat concrete) through to the medium-to-high
suction of gypsum or cement-based undercoat plasters.
Most backgrounds which normally require a bonding agent
to provide adhesion can be directly plastered with Thistle
Durafinish (e.g. MR plasterboards, cast in-situ concrete,
previously plastered surfaces) provided they are clean,
sound and reasonably dry.
according to this it should be fine on gypsum backingg coats
