Tylovis PVA 18
Tylovis® PVA 18 is used in dry mixed mortars in combination with gypsum or cement as a co-binder. Because of its high adhesive strength to paper, Tylovis® PVA 18 is especially recommended for gypsum based adhesives, jointing and trowelling compounds, which are used to install plaster board walls and ceilings. Tylovis® PVA 18 reduces the surface tension of water and increases workability and pumpability of mortars.
The recommended concentration should be 0.5 – 1.5 % by weight, calculated on the dry mix mortar.
