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

Imagine coming home after a long day, only to notice that unsightly patches of plaster have formed on your walls, leaving behind a blistering, peeling facade. This frustrating phenomenon, known as plaster blowing, can disrupt the comfort and aesthetics of your living space. Not only is it an eyesore, but it may also signal underlying issues that could lead to more significant damage if not addressed promptly. Thankfully, you're not alone, and today we’ll explore how to stop plaster blowing on internal walls effectively.

What Causes Plaster Blowing?

Understanding the root causes of plaster blowing is crucial for effective preventative measures. Here are some common reasons:

• Moisture intrusion: Water is the most significant enemy of plaster. This can come from leaking pipes, condensation, or rising damp.
• Temperature fluctuations: Rapid changes in temperature can cause expansion and contraction, leading to cracks.
• Poor application: If plaster wasn’t applied correctly or the surface wasn’t properly prepared, it may weaken over time.
• Inadequate drying time: Plaster needs sufficient time to dry after application; rushing this process can lead to future problems.

Being aware of these factors helps us tackle plaster blowing head-on.

How to Stop Plaster Blowing: Step-by-Step Guide

Here’s a practical, step-by-step guide to help you stop plaster from blowing on your internal walls:

1. Identify the Problem Areas

Start by examining your walls thoroughly for signs of plaster damage:

• Check for bubbles or blisters in the plaster.
• Look for cracks that indicate structural issues.
• Pay attention to damp areas or any other signs of moisture.

2. Assess for Moisture Issues

Once you’ve identified heavily damaged areas, the next step is to check for moisture sources:

• Use a moisture meter to check humidity levels in your walls.
• If you detect leaks, repair them promptly. You may need to consult professionals for complex plumbing issues.
• Ensure adequate ventilation to prevent condensation buildup, especially in areas like kitchens and bathrooms.

3. Remove Loose or Blowing Plaster

To stop further damage, you have to tackle the affected plaster:

• Use a scraper to remove any loose plaster gently. Avoid damaging the underlying structure.
• For larger areas, a hammer and chisel can help break the plaster gently.

4. Prepare the Surface

Before reapplying plaster, ensure that the surface is ready:

• Clean the wall to remove dust, dirt, and any remnants of moisture.
• Apply a bonding agent to ensure the new plaster adheres correctly. This is particularly crucial if the plaster was blowing due to insufficient adhesion originally.

5. Replaster the Affected Section

Depending on the size of the area:

• Mix your plaster according to the manufacturer’s instructions.
• Apply it evenly using a trowel, ensuring a smooth finish. Aim for a thickness of 5mm for standard plaster.
• Allow adequate drying time as specified. On average, plaster takes about 2-4 days to dry fully.

6. Implement Preventative Measures

To prevent future issues, here are some essential tips:

• Regularly check for and address moisture issues.
• Maintain proper heating and ventilation throughout your home.
• Consult with local plastering professionals for any persistent problems, as they can provide tailored solutions to your specific needs. For some expert help, visit London Plastering Service
