The spatula technique involves spreading, smoothing, and texturing filler and levelling compounds using finishing trowels, notched spatulas, or structured tools. In painting and decorating, it is used to level uneven surfaces, cover joints, and create smooth substrates before painting. Decorative spatula techniques such as Venetian plaster, concrete-look finishes, or marmorino produce high-quality wall surfaces with a three-dimensional appearance. Key factors include the correct material consistency, even pressure, and respecting drying times between coats. Achieving professional results requires practice and thorough knowledge of the materials being used.
