The main applications for gypsum based construction materials are plasters (hand or machine applied), trowelling compounds, joint fillers and adhesives.
Gypsum is a well-established construction material for interior applications. It offers good workability and its setting time can be adapted for every application as required. Gypsum building materials generate a comfortable living atmosphere due to good humidity balance. Additionally, gypsum shows excellent fire resistance. However, it is not water resistant, therefore only interior use is possible. Combinations of gypsum and hydrated lime are very common in plaster formulations.
Filter applications by:
Hand applied plasters
Gypsum based hand plasters are used for smaller areas as well as during renovation. They are stirred either by hand or with a machine and applied manually, usually with a trowel. Gypsum based hand or bonding plasters are less delayed than gypsum based machine plasters.
Gypsum based and gypsum-lime based machine spray plasters are mixed and applied in continuously working plastering machines. They are used for a highly efficient coating of walls and ceilings and applied in one layer (ca. 10 mm thick).
Gypsum based trowelling compounds are used to level different wall or ceiling substrates. They are applied in thin layers and provide a very smooth and decorative surface, which can be then painted.
Gypsum based jointing compounds are used for filling the joints between gypsum plasterboards or gypsum fibre boards. Setting times vary considerably depending on the geographical region and application.
Tylose MC products for gypsum application are optimised in many ways and offer:
High water retention over the whole workability time
Optimised consistency
Reduced lump formation
In addition dispersing agents (e. g. Tylovis EP 28), air entraining agents (e. g. Hostapur OSB) and starch ethers (e. g, Tylovis SE 7) improve workability and are used in combination with Tylose MC.

Emulsion based systems
Tylose® improves water retention, consistency and adhesion of emulsion based building materials.
