Brought to you by Scott Lehr, PA at RESF and The Listing Team
1. Regular Inspection
Inspect your stucco exterior twice a year (spring and fall). Look for:
- Hairline cracks (less than 1/8 inch)
- Discoloration or staining
- Bulging or soft spots indicating moisture intrusion
- Peeling paint or white, powdery residue (efflorescence)
2. Cleaning Your Stucco
- Pre-wet wall from bottom to top.
- Rinse from top to bottom using a hose with a spray nozzle.
- Apply mild detergent to stains and scrub gently.
- Rinse thoroughly with clean water.
Tip: Avoid pressure washers to prevent damage.
3. Repairing Cracks and Holes
Small Cracks (under 1/8 inch):
- Clean area with a brush.
- Apply stucco-safe acrylic caulk.
- Smooth and let cure.
Larger Cracks or Holes:
- Remove loose stucco.
- Apply bonding agent.
- Patch with stucco mix and match texture.
- Let cure fully before painting.
