Traditional stucco, otherwise known as cement plaster, is a Portland cement based product also offered by Creative Coatings, Inc. Cement stucco has been used over wood frame construction in the United States before the early 1900's, long enough to develop proven procedures for installation.
During the preparation stage of the work, the first step is to apply a vapor barrier to the exterior of the building if it is wood frame construction. Next, galvanized steel lath is affixed to the substrate; this forms a positive base which allows cement to adhere. The surface of the building is now prepared to hold the cement plaster. The first coat of cement applied to the metal lath is called a scratch coat. This coat, which is between 1 / 4 inches and 3 /8 inches thick, provides a positive bond and adds strength to the next layer of masonry product to be applied. The next step is to apply the color coat. Color is determined by selecting cement and an aggregate color and is often modified by adding mineral oxide pigments to the cement mix. The color is mixed in with the cement in a modified plaster mixer to ensure even color distribution. You should never need to "touch-up" because the color is mixed evenly throughout the cement. The texture of the finish coat is achieved by selecting the appropriate aggregate size and using special techniques during and after the application of the cement plaster finish coat. Texture gives character and substance to the cement plaster. It can be used to provide depth, continuity, highlights and even obtain the look of an entirely different construction material such as stone masonry construction or brick (Brickote).
