ZipWall Containment Setup for Mould Remediation in Rouse Hill NSW | Step-by-Step Guide
By Michael Nguyen
Recently, our team completed a mould remediation project in Rouse Hill, NSW, where we installed a professional ZipWall containment system to isolate a contaminated area and prevent mould spores from spreading throughout the property.
Proper containment is one of the most important steps in any mould remediation project. Whether you're dealing with visible mould growth, water damage, or demolition work, establishing an effective containment barrier helps protect unaffected areas and improves remediation outcomes.
In this article and video, we'll demonstrate how to install a ZipWall containment barrier using 200-micron plastic sheeting, a zipper door system, and negative air pressure principles commonly used in professional mould remediation projects.

Why Containment Is Critical During Mould Remediation
Mould spores become airborne when contaminated materials are disturbed. Without proper containment, these spores can travel into unaffected rooms and create additional contamination issues.
A professionally installed containment barrier helps:
- Prevent cross-contamination
- Improve HEPA filtration effectiveness
- Maintain negative air pressure
- Protect occupants and workers
- Improve overall remediation outcomes
At AAA Mould Removal, containment forms a critical part of our remediation process and is implemented in accordance with industry best practices.

Materials Required for a ZipWall Containment Setup
For this Rouse Hill mould remediation project, we used:
- 200-micron plastic sheeting
- Heavy-duty containment tape
- ZipWall zipper door kit
- Stanley knife
- HEPA air scrubber (when negative air pressure is required)
These simple materials create a highly effective containment barrier that isolates the work area while allowing safe access for technicians.

Step 1: Install the Plastic Sheeting
The first step is measuring the doorway and cutting the plastic sheeting to size.
The plastic should extend beyond the doorway opening so it can be securely attached to the surrounding door jambs and wall surfaces.
Using durable 200-micron plastic helps minimise tearing and ensures the containment remains intact throughout the remediation process.
---
Step 2: Seal the Plastic to the Door Jambs
Once positioned, the plastic sheeting is taped securely to the doorway.
Every edge should be sealed to prevent air leakage.
Even small gaps can reduce containment effectiveness and allow mould spores to escape into clean areas of the property.
A properly sealed containment barrier is essential for maintaining control of airborne contaminants.
---
Step 3: Install the ZipWall Zipper Door
After the containment plastic has been installed, the zipper is attached vertically to create an access point.
The zipper system allows technicians to enter and exit the contained area while maintaining an effective barrier between contaminated and uncontaminated spaces.
Once the zipper is attached, a Stanley knife is carefully used to cut the plastic behind the zipper, creating a functional doorway.
This creates a professional containment entrance that can be repeatedly opened and closed throughout the remediation process.

Why Airtight Containment Is Essential for Negative Air Pressure
Many mould remediation projects require the use of negative air pressure.
Negative air is created using HEPA-filtered air scrubbers that continuously remove air from the containment area.
This creates a pressure differential that causes air to flow into the containment rather than allowing contaminants to escape.
For negative air pressure to work correctly, the containment barrier must be airtight.
If the plastic sheeting is loose or poorly sealed:
- Negative pressure can be lost
- Airflow becomes ineffective
- Mould spores may escape
- Cross-contamination risks increase
This is why our technicians ensure containment barriers are installed tightly and thoroughly inspected before remediation begins.

Common Applications for ZipWall Containment Systems
Professional containment systems are commonly used during:
Mould Remediation
Containment prevents mould spores from spreading while contaminated materials are removed and cleaned.
Water Damage Restoration
Containment helps isolate affected areas during demolition and structural drying.

Frequently Asked Questions
What plastic should be used for mould containment?
Professional remediation contractors commonly use 200-micron plastic sheeting due to its durability and resistance to tearing.
Does every mould remediation project require negative air pressure?
Not always. The need for negative air depends on contamination levels, project scope, and the risk assessment conducted before remediation.
Why is a zipper door used in containment?
A zipper door provides convenient access while maintaining containment integrity throughout the remediation process.
Can containment stop mould spores from spreading?
Properly installed containment significantly reduces the risk of mould spores spreading to unaffected areas during remediation.
