Coats of paint and wallpapers 

Before applying the coating the plaster must be dry. Due to the very good drying behaviour of MultiGips plasters, with sufficient cross-ventilation and a dry background, the final wall configuration can be started already after ca. 2 weeks. In order to achieve an even absorbent condition, the plaster surfaces are to be primed. The priming, matched to the gypsum plaster as background as well as the subsequent covering is a performance of the subsequent work, as a rule therefore of the painter or tile layer. For wallpapering on modern and rational lightweight gypsum plasters, e.g. MultiGips MP 100 Leicht or MP 80 Leicht, mainly primers with thinned paste have proved themselves.


With the execution of the wall finish with paintwork or wallpapers The BFS Advisory Leaflets “Surface coatings, wallpapering and pasting work on interior plaster” and “Technical guidelines for wallpapering and pasting work” are to be observed. For normal requirements the latter demands a compressive strength of the background for coatings and wallpapers of at least 1.0 N/mm2. Gypsum plasters from MultiGips regularly achieve a compressive strength of 2.0 N/mm2 upwards and offer the person carrying out the work an increased security significantly above the required values.

Composite waterproofing 

Gypsum plasters are in a position to take up, e.g. from the air and, with sinking relative humidity, again release temporary moisture produced. This air condition regulating effect is above all a very valued advantage in dwellings, offices and public buildings. 

Gypsum plaster can also be employed in kitchens and bathrooms of dwellings or in comparable rooms in, for example, hotels or hospitals. This applies expressly also for areas temporarily and to a small degree affected by sprayed water next to wash basins, baths or showers in these rooms.


Additional security is offered here by MultiGips MP AquaProtect with significantly reduced ability to take up water.


Gypsum plaster of the mortar group IV, according to this advisory leaflet, is suitable as background in the Loading Classes 0 and A01. Class 0 stands for “wall and floor surfaces which are only occasionally and for a short time slightly loaded with sprayed water”, given as example are bathrooms “with normal domestic use without floor drain with bath or shower basin”. Class A01 includes “wall surfaces which are loaded with sprayed water only occasionally and for a short period”, which applies approximately for walls loaded with sprayed water in bathrooms with normal domestic usage and with floor drain.  

Tiles 

Gypsum plaster which is subsequently to be tiled is to be applied single-layer with a minimum thickness of 10 mm. With a compressive strength of at least 2.0 N/mm2 all gypsum and calcined gypsum plasters from MultiGips form an underground of sufficient load bearing capability for tiles. Additional security is gained by the worker here also, again using MultiGips MP AquaProtect. The high quality gypsum plaster developed specially for the employment of tiles is thoroughly hydrophobias and with its compressive strength of ≥ 3.3 N/mm2 lies far above the requirements of the standard specification.

The plaster must be dry before the start of tiling work.  In spray water loaded areas a composite waterproofing is to be applied according to the specifications of the respective manufacturer. The tiles can be laid securely using suitable thin-layer adhesives on a dispersion or cement basis using the normal technique.
