Hand gypsum plasters
smaller surfaces as well as with refurbishment tasks and renovation MultiGips
hand plasters represent an ideal solution. The gypsum plaster MultiGips
RotWeiss 100 and MultiGips RotWeiss 60 are suitable for all backgrounds in
particular also for weakly absorbent backgrounds such as concrete. MultiGips GoldWeiss ready-to-use gypsum plaster is planned especially for normally
absorbent, rough rendering bases such as masonry.
Practical tips for the working of hand gypsum plasters
- MultiGips hand gypsum plasters are worked sinlge-layered up to 25 mm. Multilayer plasters are to be avoided, as the correct bonding of the individual layers on each other is no longer guaranteed. If, in exceptional cases, plastering has to be multilayered the bottom layer of plaster in even moister form is to be combed swallow-tailed; the following layer is to be applied, after complete drying of the lower layer, in the direction of the combing grooves.
- The minimum plaster thickness with plastered surfaces, which are to be tiled, is 10 mm. Their surface may not be sand-floated or smoothed. It must be dressed only with the reverse side of a wall scraper in order to obtain a rough surface .
- Ensure good cross-ventilation after plastering so that the moisture can be extracted. Poor ventilation can – particularly in winter – lead to a formation of sinter skin. If a sinter skin has formed drying will be hampered. In this case sand lightly
