Cement stucco is a common building material in many construction projects today. It is widely appreciated for its durability, resilience and longevity. The stucco is highly water-resistant and can effectively protect the building from the elements, making it a popular choice for exterior coating. However, to ensure that it remains effective, the stucco needs periodic maintenance and painting.
One common way of painting stucco in Calgary is by using elastomeric paint. Elastomeric paint comprises synthetic resins and fillers that form a thick, rubbery coating that can bridge and seal cracks in the stucco. While elastomeric paint is highly effective for painting other surfaces, it is generally not recommended for cement stucco.
Dynamic Stucco Repair and Painting in Calgary share reasons why:
1. Stucco Breathability
Cement stucco is highly permeable, and the stucco surface can breathe out moisture absorbed from the inside. Using elastomeric paint creates a non-permeable barrier on the surface that locks in the moisture, leading to potential damage to the stucco. Trapped moisture may encourage the growth of mould and mildew, which can further damage the stucco and negatively impact indoor air quality. Learn about stucco repair in Calgary.
2. Adhesion
The stucco surface is relatively smooth, making it difficult for the elastomeric paint to stick effectively. The elastomeric coating can quickly peel off from the surface, exposing the underlying stucco to damage from the elements.
3. Cost
Elastomeric coating is relatively inexpensive, but it needs to be applied in thicker coats to achieve the desired rubbery finish. Elastomeric paint is typically used on surfaces with high levels of movement or flexibility, such as roofs or masonry. Cement stucco, however, has little or no movement; hence, an elastomeric coating is an inappropriate product.
4. Maintenance
Applying elastomeric paint on cement stucco means that in future, it will be challenging to carry out maintenance repairs on the stucco. The thick elastomeric coating would require that any repair or patching of the stucco must be done by removing the entire elastomeric layer, thus adding to the repair cost. In conclusion, while elastomeric paint is ideal for some surfaces, it is not the best option for painting cement stucco.
The recommended paint of choice for cement stucco is breathable paint, such as acrylic paint, without elastomeric properties. This type of paint allows the stucco surface to breathe while at the same time protecting it from the elements. It usually has a better UV rating, easier to maintain, and will last as long as the elastomeric coating.
