Parging is tough, but like anything else, it wears over time. If you spot cracks in your home’s parging, especially on the foundation, it’s natural to worry. Don’t panic—this guide explains why parging can fail and what you can do about it.
Why Parging Cracks: A Quick Overview
Parging serves as a protective layer over concrete or masonry, shielding the foundation from weather elements and providing insulation. However, cracks can occur over time due to the natural characteristics of the material.
Causes of Parging Cracks:
- Drying and Brittleness: Parging is made of cement, which dries and becomes brittle over time, especially when exposed to moisture and sunlight.
- Settling Foundations: Cracks may result from the settling of the foundation, leading to stress on the parging layer.
- Mechanical Damage: External factors like paving materials, equipment, and foot traffic can contribute to cracks in parging.
- Temperature Fluctuations: Extreme temperature changes can impact the flexibility of the parging, leading to cracks.
- Foundation Movement: Movement caused by settlement, frost heave, or hydrostatic pressure can create stress points in the parging.
- Dry Rot and Plumbing Leaks: Moisture-related issues, such as dry rot or plumbing leaks, can expedite the drying process, contributing to cracks.
Understanding these causes helps in addressing and preventing parging issues, ensuring the longevity and effectiveness of this protective layer.
Are Cracks in Parging Normal? Explained Simply
Yes, cracks or holes in parging are quite common. Whether it’s considered normal depends on the cause. If cracks appear suddenly, it could signal more significant issues requiring professional inspection. Regular checks can help address minor cracks and ensure the longevity of your parging.
Dealing with Parging Cracks: A Simple Guide
If you notice cracks in your parging, consider these steps:
- Consult a Professional: Get a thorough inspection to determine the cause and necessary actions. Sudden or severe cracks may need expert attention.
- DIY Repair Steps:
- Remove Cracked Parging: Safely scrape off flaking parging with a suitable tool and protective gear.
- Sand the Surface: Use a wire brush to smooth the concrete surface without causing damage.
- Apply Bonding Sealer: Use a bonding sealer for a protective layer against future moisture and cracking.
- Use Parging Compound: Apply a new layer of parging compound, considering professional help if uncertain.
- Curing Time: Allow at least 24 hours for curing between layers for a seamless finish.
- Caulk Cracks: Finish by applying silicone caulk to seal any remaining cracks and holes.
