In Chandler, AZ—where stucco homes dominate the landscape—homeowners often wonder if sanding stucco is a smart way to refresh their walls. Whether you’re trying to smooth out rough patches, prep for a new coat of paint, or repair damaged areas, sanding can be a helpful tool—but it’s not as simple as sanding drywall.
In this guide, we’ll break down whether you can sand stucco, when it’s appropriate, the tools you’ll need, and what to avoid for a smooth, long-lasting finish.
Key Takeaways
Yes, you can sand stucco—but only under the right conditions and with proper tools.
Use sanding to smooth out small rough patches, repair minor imperfections, or prepare for refinishing.
Power tools and respiratory protection are essential for safe and effective sanding.
In Chandler’s dry, dusty climate, proper sealing and maintenance post-sanding are crucial.
When Can You Sand Stucco?
Sanding stucco is possible, but only in limited situations, such as:
Smoothing small rough patches or repairs
Prepping surfaces for paint or recoat
Removing loose or flaking paint
However, do not sand structural cracks or deep imperfections—these require patching, not smoothing.
Stucco in Chandler, AZ is often exposed to intense sunlight and monsoon conditions, so it’s important to assess the condition of your wall before sanding. If you’re unsure, consult a professional for a surface evaluation.
Tools You’ll Need
Sanding stucco requires special tools and safety gear due to the hardness and dustiness of the material:
Angle Grinder with Diamond Cup Wheel – For heavy-duty sanding
Pole Sander with 60- or 80-grit Sandpaper – For lighter surface smoothing
Respirator or Dust Mask – To avoid inhaling silica dust
Safety Goggles and Gloves – To protect against flying debris
Always sand with a light hand, as aggressive sanding can expose the base coat or create uneven textures.

Steps to Sand Stucco Safely
Inspect the wall – Look for hairline cracks or moisture stains that need repair before sanding.
Clean the surface – Remove dust, cobwebs, and any loose material.
Use protective gear – Always wear a respirator, gloves, and eye protection.
Start with low pressure – Begin sanding in a circular motion using a pole sander or angle grinder.
Work in small sections – Don’t overdo one spot; keep your strokes consistent.
💡 Tip: Never use wet sanding on exterior stucco—it can lead to water penetration and damage.
After Sanding: What Comes Next?
Once your stucco surface is sanded:
Apply a bonding primer if you’re repainting
Patch deeper imperfections with stucco mix
Seal the surface to protect from Chandler’s intense sun and monsoon rains
