Cinder block retaining walls serve a vital purpose in landscape architecture, such as stabilizing sloped terrain or creating raised beds for planting. However, the functionality is not the only thing that matters. The appearance of a retaining wall also plays a significant role in the overall aesthetic of an outdoor space.
A plain, gray cinder block wall may provide necessary support, but it can also look uninviting and unsightly. Fortunately, stucco, a cement-based plaster that adds texture and color, can transform a plain block retaining wall into a beautiful and modern-looking feature. There are several stucco finish options that can be applied to concrete block retaining walls to give them a stylish appearance.
Preparing the Concrete Cinder Block Retaining Wall
Prior to applying a stucco wall, prepare the concrete blocks to ensure the stucco adheres correctly. First, remove any loose debris, such as dirt and dust from the wall surface. Then, use a power washer to wash the wall thoroughly. Allow the wall it to dry completely before proceeding. Next, repair any cracks or holes on the wall’s surface using an appropriate patching compound. Once the wall is clean and smooth, apply a layer of concrete bonding agent to the surface. This will help the stucco adhere to the wall.
Several options of stucco finishes are available for cinder block retaining walls, each with a unique texture and look. The smooth finish is the most common stucco finish and is ideal for creating a modern look. To achieve a smooth finish, apply the stucco using a trowel or sprayer followed by a float or trowel to create a smooth, flat surface. The smooth finish can be left as is or paint can be applied to customize the appearance of the retaining wall.
The dash finish is a popular stucco finish that involves adding small stones or other aggregates to the stucco mix, creating a textured and rustic appearance. The size of the stone or aggregate can vary, depending on the desired effect. To achieve a dash finish, apply a base coat of stucco to the wall, then throw or “dash” small stones onto the surface. Once the stones are in place, apply a second coat of stucco to cover the stones, leaving the desired texture behind.
The roughcast finish involves adding coarse aggregates to the stucco mix, creating a rough and textured surface. The roughcast finish is ideal for creating a natural, earthy look. To achieve a roughcast finish, first, apply a base coat of stucco to the wall. Then, apply a second coat of stucco, throwing or “casting” coarse aggregates onto the surface. The second coat should be applied thicker than the first, allowing the aggregates to show through.
The lace finish is a stucco finish that creates a delicate and intricate pattern on the wall’s surface. To achieve a lace finish, apply the stucco to the wall using a sprayer or trowel, then use a brush to create a textured pattern in the stucco. The result is a finish that resembles lace or delicate embroidery.
The sand finish is a stucco finish that involves adding fine sand to the stucco mix, creating a textured and subtle appearance. The sand finish is ideal for creating a natural look that blends well with surrounding landscape features. To achieve a sand finish, apply the stucco to the wall using a trowel, and then sprinkle fine sand over the surface of the stucco before it dries. A properly applied sand finish will create a subtle texture that adds depth and interest to the retaining wall.
Color and Paint
Once the stucco finish is applied, it’s time to add color and paint to enhance the wall’s appearance. The stucco can be tinted with pigment to create a desired color or painted after the stucco has dried. Paint provides an additional layer of protection for the wall, preventing water penetration and prolonging the wall’s lifespan.
Keeping a stucco retaining wall looking its best requires regular maintenance. Inspect the wall for any cracks or damage and repair as necessary. Clean the wall periodically with a gentle soap and water solution, avoiding the use of harsh chemicals that can damage the stucco finish. Larger areas or stubborn stains requires a power washer. However, be careful not to damage the stucco surface when using that type of equipment.
Additional Information About Stucco Surfaces
Stucco is not used only for retaining walls but can work on other surfaces, such as exterior walls of buildings, interior walls, and ceilings. It is known for its durability, versatility, and aesthetic appeal.
When choosing a stucco finish for a retaining wall, consider the climate and weather conditions in the area. For instance, a smooth finish may not be the best option in areas with high humidity or heavy rainfall, as some finishes can be prone to cracking or peeling.
The cost of applying stucco finishes to retaining walls can vary depending on several factors, such as the size of the wall, the chosen finish, and the complexity of the project. Experts recommend getting quotes from multiple contractors and comparing their prices and services before making a decision.
In addition to stucco, other materials can also be used to enhance the appearance of retaining walls, such as stone veneer, wood cladding, or decorative tiles. These options may provide a different look and feel compared to stucco finishes and may be better suited for certain architectural styles or personal preferences.
Homeowners should also check with their local building codes and regulations before applying stucco finishes to their retaining walls. Some areas may have specific requirements or restrictions regarding the use of certain materials or finishes, and failure to comply with these regulations can result in fines or legal issues.
What to do if Stucco Finish is Damaged
When a stucco surface on a retaining wall becomes damaged, it is unsightly and potentially hazardous. Fortunately, there are steps that homeowners can take to address this problem and restore the appearance and function of their retaining wall. The first step in repairing a damaged stucco surface on a retaining wall is to assess the extent of the damage.

Depending on the severity of the damage, homeowners may need to enlist the help of a professional to make repairs.
Prepare the Surface

This may involve cleaning the area with a power washer to remove any dirt, debris, or loose stucco from the damaged area. Homeowners may also need to apply a bonding agent to the surface to ensure the new stucco adheres properly.
After the surface is prepared, homeowners can begin making repairs. This may involve applying a new layer of stucco to the damaged area, carefully matching the color and texture of the existing stucco as closely as possible. Depending on the severity of the damage, homeowners may need to apply multiple layers of stucco to build up the damaged area and create a smooth, even surface.
Seal and Protect
Once the repairs are made, seal and protect the new stucco surface to prevent future damage. Homeowners may need to apply a sealant to the surface to protect it from water, moisture, and other environmental factors that could cause further damage. They may also need to apply a coat of paint or other protective finish to the surface to ensure that it remains durable and provides an attractive appearance.
