Trickle plaster is plaster with coarse-grained sand and fine gravel , which is either thrown on directly like coarse spray plaster or roughened like black and scratch plaster after a short drying time. Part of the aggregate trickles down again. Floating plasters have a distinctive structure. It is usually only used outdoors.

This wall plaster is typical of the Baroque period , where the wall surface is then structured by smooth pilasters or pilasters , as well as bezels around doors, windows and other openings in the masonry, as well as any cartouches for decorative painting. This creates an impression of stone masonry imitation (rough stone with a smoothed edge). Here, the Rieselputz consistently carries the darker color job , often colored, while the pilasters and window surrounds are widely held lighter or neutral white to gray.

A trickle plaster is particularly suitable for renovating old buildings . Due to the larger surface and the coarse grain size, a damp wall can dry out faster through the trickle plaster and any efflorescence is much less noticeable than on smooth plastered surfaces. They also hide unevenness in the wall, and a slightly wavy surface even contributes to the livelier play of the wall surface.
