How to Stop Plaster Blowing on Internal Walls: A Comprehensive Guide

Imagine walking into your beautifully decorated living room, only to be met with unsightly cracks and peeling plaster. If you've ever faced this frustrating scenario, you know the struggle of maintaining the integrity of your home's walls. Blowing plaster not only looks unattractive but can lead to more serious issues and costly repairs. In this guide, we'll explore the causes of plaster blowing, practical tips to prevent it, and how you can maintain your internal walls for years to come.

Understanding the Causes of Plaster Blowing

Before we dive into solutions, it’s crucial to understand what causes plaster to blow. This phenomenon can be attributed to several factors:

1. Moisture: One of the leading causes of plaster failure is moisture. When water seeps into the plaster, it expands and can separate from the internal wall, leading to blow-outs. This is particularly common in areas with high humidity levels or leaks from plumbing.
2. Poor Application: If plaster is applied poorly or not given enough time to cure, it can weaken over time. This is why hiring a professional plasterer is essential. For skilled help, check out our About - Professional plastering team.
3. Temperature Changes: Rapid changes in temperature can cause the plaster to contract and expand, leading to cracking and eventually blowing.
4. Old Walls: Homes in areas like Islington or Hammersmith with older plaster may be more prone to issues because of deterioration.

Practical Tips to Prevent Plaster Blowing

1. Ensure Proper Ventilation

Moisture control is vital for keeping plaster intact. Here’s how to improve ventilation:

• Open windows regularly to allow fresh air circulation.
• Use dehumidifiers in high-moisture areas like kitchens and bathrooms.
• Install vents to keep air flowing, especially in cookie-cutter homes that may lack natural airflow.

2. Maintain Consistent Temperature

To combat the effects of temperature on plaster, consider:

• Installing thermostats to regulate indoor temperatures, especially during winter.
• Avoiding abrupt heating changes, like turning up radiators too quickly.

3. Inspect for Leaks Regularly

Conduct routine checks for any signs of leaks, especially in:

• Bathrooms and kitchens where plumbing is prone to wear.
• Basements or crawl spaces that may face water intrusion.
• Entryways that regularly get wet from outdoor conditions.

4. Use Quality Materials

Investing in quality plaster products can make a huge difference. Look for:

• High-quality pre-mixed plaster that contains additives for better moisture resistance.
• Waterproof sealants for areas prone to exposure. Check out our Wall skimming services for options that can help enhance your walls.
