 The basic rule for installing gypsum stucco on a facade is not to use gypsum stucco on the facade. Gypsum is not designed for exterior work. There are cement, cement-gypsum-pozzolanic, as well as polyurethane stucco suitable for exterior work.

First you need to make a marking with a plumb line, level, tape measure and colored cord and pencil. Stucco is glued to mounting adhesives on a cement or polymer basis and additionally fixed with dowels or any other available method. Fixing the heavy elements can also be carried out with the help of dowels. The joints are lapped and sealed with waterproof putty in 2-3 passes and sanded.

unpainted stucco should be painted with facade paint, and colored impregnated with a hydrophobic impregnation or covered with a transparent acrylic water-dispersion varnish.
