Stucco’s durability,long lifeandstriking appearancemake it an appealing finish for homes. Compared to other siding materials, ittypicallydoesn’t require a lot of maintenance.Butcracks and holesdo occasionallyappear.And when that happens,it’s important to seal them. If left open, water can find its way in,leading to larger and moreburdensomeproblems.Use one of these two methodsfor how to repair stucco holesand preserveyour home’sattractivefinish.
Small Holes and Cracks
Step 1: Clean the Surface
Use a stiff-bristled brush to clean out any loose material in and around the hole or small crack being patched.
Step 2: Apply a Patching Material
Using a putty knife or trowel, apply DAP All-Purpose Stucco Patch. It’s ready-to-use,eliminating the need for messy mixing. It can be used to fill holes as wide as your palm and up to½ inchdeep. For patches more than¼ inch deep, apply two or more layers of the patching material, allowing each layer to dry before applying the next.
Step 3: Smooth the Patching Material
Use a rubber float to smooth the patch and blend with the existing stucco surface. For best results, wet the float first. DAP All-Purpose Stucco Patch dries in 72 hours, depending on application conditions and thickness of application.
Bonus Tip: If the stucco has a textured finish, try these tricks for texturizing the patchedarea while it’s still wet:
Use an old paint brush or stiff-bristled brush to stipple the patching material and create a texture.
Or, put a small amount of sand on a small, rigid piece of cardboard. Hold it up to the patched area and blow the sand onto the patch. The sand will stick to the patching material, creating a texture.
Step 4: Prime the Patched Area
When the patch is dry, brush on Zinsser Bulls Eye 1-2-3 Primer before painting, to seal the patch and provide an even base coat for the paint to cover.Let it dry and paint.
Large Recurring Cracks
Step 1: Clean the Surface
Use a stiff-bristled brush to clean out any loose material in and around the crack.
Step 2: Fill the Cracks
Use DAP Elastopatch Pro-Grade Elastomeric Patching Compound to fill reoccurring gaps and/or cracks up to ¼ inch wide x ½ inch deep. Available in smooth and textured finishes, it provides a permanently flexible fill that won’t crack, crumble or fall out as the surface expands and contracts over time. For deeper gaps, apply it in multiple layers, letting it dry between applications.
Step 3: Tool the Surface
Before the patching compound dries, tool the patched area to achieve the desired finish (ElastoPatch is notsandable). For smooth textures, use a putty knife. To achieve a rough texture, tool with a rubber float and for a very rough surface, use astiff-bristled brush.
Step 4: Prime the Patch
When the patching compound is dry (allow at least 24 hours), prime itwith Zinsser Bulls Eye 1-2-3 Primer. Let it dry and paint.
