Abstract: The feasibility of preparation of building exterior wall coatings with municipal sludge
filler is studied in laboratory. Th black powder obtained from the sludge pretreatment by thermally
carbonized method is used to prepare the coatings. The coating performance is evaluated by
viscosity, porosity and water absorbency. The basic formula of the coatings is: sludge 31.58 wt%,
benzenoic acid emulsion 15.79 wt%, carboxyl, sodium methylcellulose 1.05 wt% and water 51.58
wt% . The properties of the coatings, such as the state in the container, water resistance, alkali
resistance and artificial climate aging resistance, can meet the requirements of the national standard
(GB/T 9755-2014). At the same time, the film hardness is 3H and the adhesion is 0, which shows

the unique advantages of the municipal sludge-based coatings.
