Stuc-Primer

Absorption-regulating primer for pre-treating highly or unevenly absorbent mineral substrates indoors. Suitable for substrates such as masonry and other mineral surfaces before applying gypsum plaster. Reduces and equalizes the absorbency of the substrate, allowing the plaster to cure evenly and reducing the risk of powdering caused by excessive absorption. Can be applied manually or by machine and should be diluted with clean water according to the application instructions before use.
