Stucco finishing: applying and painting
July 24th, 2008Generally, when we say stucco we mean a mixture of plaster and a cement base that is typically applied over framed and solid walls in three layers. Mixing in sand makes this type of finish extra-coarse. In order to add color you either mix in pigment or simply paint stucco. Besides, you can add various textures to stucco finishing.
It should be noted that the type of cement used in the stucco mixture depends on the climatic conditions and desired texture. Thus stucco finishing can be applied over some existing surfaces, such as concrete block or reapplied over older stucco. Usually stucco is applied over a base of wire mesh or building paper. Specialists insist on a day or two-long drying period for the first layer before applying the second and third coats. On the opposite, after applying the final layer, you should keep the stucco finishing moist for a few days so it can cure nicely.
As soon as the stucco is applied and the pigment is mixed right into the concrete-like material to add color this type of surfacing will hold up for many years. Another important aspect is that once you’ve painted the stucco, it will need repainting every few years.
It’s necessary to always keep in mind that stucco is porous and it means that moisture passes directly through. As a result, in warmer and drier climate areas, painting doesn’t affect this process as much as it does in colder climate areas. That’s why, before painting your stucco wall consult the local contractors for advice. If you made up your mind to paint stucco, then acrylic latex paint specially formulated for stucco surfaces will be an excellent choice.
In order to achieve the best possible result, the surface must be clean and sound. In case the stucco is in good shape, scrubbing the surface with a stiff nylon-bristle brush and a special detergent may be all it takes. However, if any of the old paint is peeling or flaking, it’s better to use a wire brush or, a scraper to make the stucco finishing look smooth.
Once you’ve intended to paint stucco but noticed that it has been painted before with a glossy paint, use a wire brush to scuff the surface and add the new paint an artificial effect of aging. Try not to pressure wash the surface because you can damage it. Besides, you can contact the best design specialists for assistance or talk to a painter about having it professionally sandblasted.
