Real Stucco


For centuries, Stucco has proven to be one of the most enduring, versatile and weather resistant exterior wall finishes available - with its variety of colors and textures, stucco continues to be one of the most popular wall systems.

Stucco is cement plaster applied over wall and surfaces inside and outside buildings. The stucco is a plaster type material that is made from cement, sand and lime. Stucco provides a hard, reliable, durable and low cost surface that requires little maintenance and can be used to obtain different textures and finishes. Stucco might be applied over metal lath which allows the stucco to adhere and become stronger.

The stucco must be applied over lath to keep it away from the frame sheathing by about one quarter of an inch. Stucco must be applied using thin coats; the first one must be forced into the lath so the mesh is entirely embedded within the stucco mix.

It is recommended to apply stucco in three different coats, adding over one inch of stucco surface once the plaster has been applied. A 3-coat stucco system consists of a scratch coat, brown coat, and finish coat. The scratch coat is applied first to provide a strong base for the system. It's embedded in metal lath, which strengthens and secures the coat. The brown coat is applied next to create an even surface for the finish coat. The finish coat is applied last, creating the decorative finish on the wall surface.


Health Advantages

Due to its lime content, the hard coat stucco is naturally exterminating insects and microorganisms.

The capillary structure of the wall keeps the wall breathing and dry which does not allow mildew to settle in or on the surface of the wall. No other wall cladding has these major advantages to keep the building healthy for a very long time.
