What Are Hairline Cracks in Drywall?
Hairline cracks are very thin and often form on walls, ceilings, or painted surfaces. These cracks are common in both drywall and plaster. They can appear in corners, along seams, or near windows and doors.
Though they might seem harmless, cracks in walls can grow over time if ignored. Learning how to fix hairline cracks in drywall or plaster can save you bigger problems down the line.
Why Do Hairline Cracks Appear?
Hairline cracks can form due to many reasons, such as changes in temperature, moisture, or poor drywall installation. Understanding the types of cracks in walls will help you fix them correctly.
Below, we’ll explore the top 11 causes of drywall cracks and share tips on preventing them.
1. Foundation Settling
As a house settles, the walls may shift slightly. This movement creates stress, leading to hairline cracks in painted walls and ceilings.
How to Prevent:
- Inspect your foundation regularly.
- Fix small foundation problems early to avoid major repairs.
2. Poor Drywall Installation
If drywall isn’t installed properly, it can lead to cracks. Loose seams or low-quality materials can cause hairline cracks in walls to form over time.
How to Prevent:
- Hire professionals for drywall installation.
- Use high-quality materials for long-lasting results.
3. Temperature Changes
When it gets hot, drywall expands. When it cools, it contracts. These small movements can create cracks in walls and ceilings.
How to Prevent:
- Keep your home at a steady temperature.
- Insulate your home to reduce temperature swings.
4. Moisture Problems
Excess moisture weakens drywall and plaster, leading to cracks in plaster and drywall. This often happens in kitchens, bathrooms, or areas with leaks.
How to Prevent:
- Fix leaks as soon as possible.
- Use moisture-resistant drywall in wet areas.
5. House Movement
Homes naturally shift over time due to weather or soil conditions. This movement can cause hairline cracks in plaster and drywall to appear.
How to Prevent:
- Regularly inspect your home for structural issues.
- Reinforce weak areas to reduce movement.
6. Low-Quality Joint Compound
The joint compound, used to smooth seams, can crack if it’s of poor quality or applied too thinly. This results in visible drywall cracks over time.
How to Prevent:
- Use a high-quality joint compound.
- Apply it evenly and allow proper drying time.
7. Drywall Tape Problems
Drywall tape holds seams together. If it bubbles or peels, it can create hairline cracks in drywall near the seams.
How to Prevent:
- Use good-quality drywall tape.
- Apply it smoothly to avoid bubbles or gaps.
8. Heavy Vibrations
Vibrations from moving furniture or nearby construction can weaken walls. Causing fixing cracks in walls to become a recurring task.
How to Prevent:
- Be careful when moving heavy items.
- Avoid banging walls or creating unnecessary vibrations.
9. Aging Materials
Over time, drywall and plaster naturally weaken, leading to hairline cracks in painted walls or ceilings. Older homes are more prone to this issue.
How to Prevent:
- Inspect walls and ceilings regularly.
- Replace old drywall when needed.
10. Rushed Finishing Work
If drywall is finished too quickly, cracks may form later. Proper sanding, priming, and painting are essential to avoid drywall cracks.
How to Prevent:
- Take time to finish drywall properly.
- Hire experts to ensure smooth results.
11. Earthquakes or Ground Shifting
Even small tremors can cause hairline cracks in walls. Homes in earthquake-prone areas often experience these cracks.
How to Prevent:
- Reinforce walls with earthquake-resistant materials.
- Use flexible joint compounds to minimize cracking.
