Stucco – what exactly is it and what you need to know
Acrylic Stucco
What is Acrylic Stucco?
Acrylic stucco is a type of exterior finish made from a mixture of acrylic resins, sand, and water. It is different from traditional stucco, which uses a cement-based formula. Acrylic stucco is applied as a coating over various surfaces, including concrete, wood, and foam insulation. It is available in pre-mixed forms, which helps maintain consistent color throughout the application process.
This type of stucco can be applied in both smooth and textured finishes, depending on the chosen technique. Acrylic stucco is not known for UV resistance, which can fade its color over time. However, it is less breathable than cement-based stucco, which requires proper installation and ventilation to prevent potential moisture issues. Acrylic stucco is widely used in residential and commercial construction and is compatible with different architectural styles.
Conventional Stucco
What is Conventional Stucco?
Conventional stucco is an exterior finish made from a mixture of cement, sand, lime, and water. It is applied as a thick coating over surfaces such as concrete, brick, or metal lath. This type of stucco is known for its hard and rigid structure, which provides a textured finish. It is typically applied in multiple layers, including a scratch coat, a brown coat, and a finish coat.
Conventional stucco is porous and breathable, allowing moisture to escape from the wall system. This characteristic helps prevent moisture buildup behind the stucco. It can be finished in a variety of textures, from smooth to rough, depending on the application technique. Conventional stucco is commonly used in residential and commercial construction. It is compatible with various architectural styles and can be painted to achieve different color options. Proper installation is essential to ensure durability and prevent cracking.
stucco repair
How is Exterior Stucco Repair Done?
Exterior stucco repair involves several steps to restore the damaged surface and maintain the integrity of the structure. The process begins with an inspection to identify cracks, holes, or areas of damage. Loose or crumbling stucco is removed using a chisel or hammer to create a clean, stable surface. The exposed area is then cleaned to remove dust and debris, ensuring proper adhesion for the new stucco.
The next step is to apply a bonding agent to the exposed area, which helps the new stucco adhere securely to the existing surface. A base coat is then applied, typically using a trowel, and it is spread evenly to match the surrounding texture. If needed, a fiberglass mesh is embedded in the base coat for additional strength and crack resistance. Once the base coat dries, a finish coat is applied to blend seamlessly with the existing stucco.
The repaired area is then textured to match the surrounding surface. This can be done using different techniques such as brushing, sponging, or troweling, depending on the original finish. Finally, the repaired stucco is allowed to cure completely before painting, ensuring a uniform appearance. Proper repair techniques help maintain the durability and aesthetic appeal of exterior stucco surfaces.

Water leaks
Acrylic Stucco Over Sand and Cement Surfaces: Hydrostatic Pressure and Water Leaks
Applying acrylic stucco over sand and cement surfaces can lead to hydrostatic pressure and water leaks if the building envelope is not properly designed. Acrylic stucco is less breathable than traditional cement-based stucco, which means moisture can become trapped behind the surface. When water seeps into the wall system through cracks or gaps, it can accumulate and create hydrostatic pressure. This pressure pushes moisture inward, potentially causing water leaks, mold growth, and structural damage.
A drainage plane is essential to prevent these issues. It is a layer installed behind the stucco that allows moisture to escape and drain away from the wall system. This layer creates an air gap that promotes ventilation and prevents water from becoming trapped. Without a proper drainage plane, moisture can build up, leading to water damage and compromising the structural integrity of the building. Proper installation of a drainage system is crucial when using acrylic stucco over sand and cement surfaces to ensure long-term durability and prevent water-related issues.
Parging Repair
What is Parging Repair?
Parging repair involves fixing damaged or crumbling parging on the exterior walls of a building. Parging is a thin layer of mortar applied to the foundation or masonry surfaces for a smooth, finished appearance and added protection against the elements. Over time, exposure to moisture, freezing temperatures, and settling of the building can cause cracks, chipping, or flaking in the parging layer.
The repair process starts with removing loose or damaged sections using a chisel or wire brush. The surface is then cleaned to ensure proper adhesion. A bonding agent is applied to enhance the bond between the old and new mortar. Fresh parging mix is then applied using a trowel, ensuring an even and consistent layer that blends with the existing surface. Once dried, the repaired area can be painted or sealed for added protection and a cohesive look.
