A Walkthrough of The Repair
As an EIFS stucco repair professional with 30 years of experience, I have come across various challenges when it comes to repairing damaged synthetic stucco or Dryvit. EIFS, or Exterior Insulation and Finish System, is a popular product that offers a cost-effective and energy-efficient solution for modern building exteriors.
In this article, I will take you through the step-by-step process of repairing a damaged corner of a building in Northville, Michigan using EIFS. Each step will be accompanied by an image to help you understand the process better.
Step 6: Applying the Basecoat with Embedded Fiberglass Mesh
Applying the basecoat with fiberglass mesh embedded is the sixth phase. The fiberglass cloth is troweled directly into the basecoat after it has been applied to a thickness of around 1/8″.
Step 1: Demolition of the Damaged Synthetic Stucco and Substrate
The first step in the repair process is to remove the damaged synthetic stucco and substrate from the corner of the building. This is done carefully to ensure that the structural integrity of the building is not compromised.
Step 7: Applying the Second Coat
The cement coat shrinks as it dries, so it is always necessary to put a second coat on when doing a repair like this. If you don’t apply a second coat, the transition to the existing stucco will be noticeable, and sometimes even a third coat may be needed.
Step 2: Sistering a Couple of 2x4s and Installing the New OSB (Plywood) to the Area
The next step is to install new OSB plywood to the area. This involves sistering a couple of 2x4s and attaching them to the existing wood framing. The new OSB plywood is then attached to the 2x4s using screws, creating a solid and stable base for the rest of the repair process.
Step 8: Applying the Top Coat and Painting
The seventh step is to apply the top coat, also known as running the finish. The finish is applied with a trowel and then textured with a float. The size of the aggregate in the finish determines the type of texture of the finish coat. Finally, the patched area is painted to match the color of the existing building, ensuring that it blends in seamlessly.
Step 3: Applying the Liquid Moisture Barrier
The third step is to apply the liquid moisture barrier to the area. This is done by applying a 4-inch fiberglass cloth to the seams and then applying the liquid moisture barrier to the flat wall. Metal is then installed at grade to protect the wood, followed by the installation of a starter track. The liquid moisture barrier and the 4-inch fiberglass cloth are then applied over the metal and track where it terminates making sure to overlap onto the OSB substrate.
Step 9: Admiring the Finished Product
Once the repair is complete, it’s time to stand back and admire the finished product. With the right tools, techniques, and experience, repairing damaged synthetic stucco can look this good. Another happy customer.
Step 4: Sticking the EPS Insulation Board
Before the foam board is attached to the wall, backwrap is put on. This is a fiberglass mesh attached to the substrate that wraps around the bottom of the foam board. Using a notch trowel and basecoat, the insulation board is then attached to the wall. To make drainage channels, the ribs are troweled vertically to the foam board’s backside.
Step 5: Prepping the Foam Board (Comin Monday)
It is time to prepare the foam board by sanding it flush and popping caulk lines on the corner to make it straight and flush after the basecoat has had plenty of time to dry.
