When it comes to patching EIFS (Exterior Insulation and Finish System) synthetic stucco, many people wonder if they can use stucco patch. The short answer is no. While traditional stucco can be repaired with stucco patch, EIFS stucco is a different beast altogether.
EIFS stucco is based on EPS styrofoam with a thin layer of fiberglass-based cement and a thin top coat over the basecoat with aggregate to give it texture. This application has a lot of movement and can expand and contract well with extreme weather conditions and structural settlement. On the other hand, traditional stucco used with stucco patch is a thick, brittle material that is very strong because of its thick cement composition.
When traditional stucco is applied to traditional stucco, it can withstand extreme weather conditions and structural settlement. However, when it is applied to EIFS (Exterior Insulation and Finish System) stucco, the Exterior Insulation and Finish System expansion and contraction properties will eventually cause the stucco patch to delaminate from the EIFS. Exterior Insulation and Finish System stucco is synthetic and cannot be patched with traditional stucco since it is much thicker and is applied in a different way.
Stucco patch won’t permanently fix damages in your Exterior Insulation and Finish System stucco, so don’t bother with it if you have that type of stucco. It could seem like a quick fix, but you’ll end up with delamination and other problems in the long run. Instead, it’s best to get in touch with an expert who works with synthetic stucco repairs to make sure the job is done right and lasts. When it comes to the upkeep and restoration of your home’s exterior, knowing the differences between classic stucco and Exterior Insulation and Finish System stucco can be invaluable. Calling a professional and having it done right the first time is more often than not the best course of action.

- Why is stucco patch not recommended for EIFS stucco?
Answer: EIFS stucco is composed of EPS styrofoam, a thin layer of fiberglass-based cement, and a thin top coat with aggregate for texture. It has the ability to expand and contract with extreme weather conditions and structural settlement. Traditional stucco, used with stucco patch, is a thick and brittle material made of cement. The expansion and contraction of synthetic stucco will cause stucco patch to eventually delaminate from the EIFS surface.
