Plaster thickness

In accordance with DIN V 18550 the average plaster thickness with single-layer interior plaster made for factory dry mortar is 10 mm. The permitted minimum thickness, which is restricted to only a few places, is set at 5 mm. On surfaces which are subsequently to be tiled 10 mm minimum plaster thickness is to be maintained. On ceiling surfaces the plaster thickness is not to exceed 15 mm. Here single-layer plastering is absolutely necessary. Should plaster thicknesses > 15 mm be necessary a metal plaster carrier must be used.

With thin layer plaster as interior plaster special requirements are to be placed on the evenness of the background. Thin layer plasters are applied single-layer in a thickness of from 3 to 5 mm. If the background is particularly uneven or is not completely flush and vertical, in practice the production of smooth wall and ceiling surfaces even plaster layers of > 10 mm can be necessary. The machine and hand plasters here offer the advantage, that even these increased thicknesses can be produced in a labour saving manner in one layer, due to their particularly good adhesion to the background and their special recipe. Single-layer working is regularly possible up to 25 mm plaster thickness, in exceptional cases up to 50 mm plaster in one layer is even possible. Through this, for example, wall heating or systems for tempering building units can be bedded in, in single-layer plaster, without problem. If it is to be plastered in single-layer in two coatings, for example with differently absorbent backgrounds, greater plaster thicknesses up to 50 mm, or with the employment of reinforcing fabric, the a first coating should be sprayed on thinly and then subsequently plastered fresh-in-fresh

Multi-layer plastering with MultiGips is not required for any building situations and tasks and should be avoided. The perfect adhesion of individual layers is then only conditionally guaranteed. If it proves in special cases that plastering in several layers is unavoidable, the bottom layer of plaster is to be combed swallow-tailed in still soft condition. The following layer is then first applied when the first is completely dried out in the direction of the comb grooves.
