Preparing the Surface for Stucco Siding Installation

Stucco process- Big Easy SidingPreparing the surface is a crucial step in stucco siding installation. It ensures that the stucco adheres properly to the surface and prevents any future issues that may arise due to a faulty surface.

Here are the steps involved in preparing the surface for stucco siding installation:

  1. Clean the surface thoroughly and let it dry completely.
  2. Repair any damages with suitable patching material and ensure it is fully cured before proceeding.
  3. Apply bonding agent as per manufacturer’s instructions.
  4. Install flashing around penetrations to prevent water infiltration.
  5. Install lath over the surface, following manufacturer’s instructions for proper fastening
  6. Install weep screed at the bottom of the wall, following manufacturer’s instructions.

Framing and Sheathing

Framing and sheathing are important steps in stucco siding installation as they provide a solid and stable substrate for the stucco.

Here are the steps involved in framing and sheathing for stucco siding installation:

  1. Design framing to support stucco weight and openings like windows and doors
  2. Choose water-resistant sheathing material (plywood, OSB, or cement board)
  3. Follow manufacturer’s instructions to install sheathing properly and stagger edges to avoid weakening substrate
  4. Apply weather-resistive barrier (WRB) over sheathing to prevent water infiltration, following manufacturer’s instructions and ensuring proper fastening and overlapping
  5. Install lath over WRB and properly fasten to framing, following manufacturer’s instructions and ensuring proper overlapping
  6. Install flashing around openings to prevent water infiltration, following manufacturer’s instructions
  7. Install weep screed at bottom of wall to allow water to escape, following manufacturer’s instructions.

Flashing and Weatherproofing

Flashing and weatherproofing are crucial steps in stucco siding installation that help prevent water infiltration and protect the building from moisture damage.

Here are the steps involved:

  1. Install flashing around all penetrations, including windows, doors, vents, and other openings in the wall. Flashing is typically made of metal and is installed in a way that creates a barrier to prevent water from seeping behind the stucco.
  2. Seal all joints and gaps with a suitable sealant, such as silicone caulk or a specialized stucco sealant. This helps to prevent water from seeping into the wall assembly and causing damage.
  3. Apply a weather-resistive barrier (WRB) over the entire wall surface. The WRB is typically a membrane that is installed behind the lath and provides an additional layer of protection against water infiltration.
  4. Install weep screed at the bottom of the wall. The weep screed is designed to allow water to escape from behind the stucco and prevent it from pooling at the base of the wall.
  5. Ensure that all flashing, sealants, and weatherproofing materials are installed in accordance with the manufacturer’s instructions and local building codes to ensure a long-lasting and effective installation.

Applying the Scratch Coat

The scratch coat is the first layer of stucco that is applied to the lath.

Here are the steps involved in applying the scratch coat:

  • Mix and apply the scratch coat material to the wall in small sections using a trowel.
  • Create a rough texture on the scratch coat surface with a scarifier or wire brush.
  • Let the scratch coat dry for at least 48 hours and moist cure it by misting it with water twice a day for at least 48 hours.
  • Inspect and repair any cracks or imperfections before proceeding.
  • Install any necessary trim or accessories before applying the next coat of stucco.

Applying the Brown Coat

The brown coat is the second layer of stucco that is applied to the scratch coat.

Here are the steps involved in applying the brown coat:

  1. Mix brown coat material per manufacturer’s instructions using cement, sand, and water.
  2. Apply the brown coat to the wall in small sections using a trowel at a thickness of approximately 3/8 inch.
  3. Level the surface of the brown coat with a straight edge.
  4. Let the brown coat dry for at least 48 hours.
  5. Moisten the brown coat with a fine mist of water before applying the final coat.

  2. Apply the finish coat to the wall in small sections using a trowel. The finish coat should be applied to a thickness of approximately 1/8 to 1/4 inch.
  3. Use a variety of finishing techniques to achieve the desired texture and appearance, such as a float, trowel, or sponge.
  4. Let the finish coat dry for at least 48 hours. The drying time may vary depending on the weather conditions and the thickness of the finish coat.
  5. Moisten the finish coat with a fine mist of water to prevent cracking as it dries.
  6. Inspect the finish coat for any cracks or other imperfections. Repair any defects with a suitable patching material and allow it to dry completely.
  7. Clean the surface of any excess debris or stucco material using a soft-bristle brush or a sponge.

Curing and Maintenance


After applying the finish coat, the stucco must be cured to ensure its strength and durability. This process involves keeping the surface moist for at least seven days by misting it with water several times a day. The stucco should be protected from direct sunlight, wind, and rain during the curing process.


Stucco requires regular maintenance to keep it looking its best and to prevent damage. This includes keeping the surface clean by washing it with water and mild soap, inspecting it for cracks or other damage, and repairing any issues promptly. It’s also important to keep vegetation away from the stucco to prevent moisture buildup and potential damage.

Tips for a Successful Stucco Siding Installation

  • Prepare the surface properly: The surface should be cleaned, repaired, and dried before applying any stucco material.
  • Use quality materials: Use high-quality stucco materials that are specifically designed for the type of surface you are working with.
  • Follow manufacturer instructions: Follow the manufacturer’s instructions carefully when mixing and applying stucco materials.
  • Work in small sections: Apply stucco in small sections to ensure proper adhesion and avoid drying out before it can be worked into the surface.

  • Use proper tools: Use the appropriate tools, such as trowels, brushes, and straight edges, to apply and shape the stucco.
  • Pay attention to weather conditions: Avoid installing stucco during extreme temperatures, high winds, or rain, as this can affect the curing process and the quality of the finish.
