Indoor air quality is a crucial factor in creating a healthy, comfortable living or working environment. While floor screeding plays an essential role in levelling surfaces and supporting flooring, it can also influence air quality through dust, moisture retention, and material emissions. Understanding how different screeding methods and materials impact indoor air can help you make informed choices for a healthier space.
Dust and Airborne Particles
Improperly mixed or installed screed can produce excess dust, which may linger in the air and contribute to respiratory issues, especially in enclosed spaces.
How to Reduce Dust Issues:
- Use low-dust screed mixes.
- Ensure proper sealing and curing to prevent surface degradation.
- Regularly ventilate spaces after installation.
VOC Emissions from Screeding Materials
Some screeds contain volatile organic compounds (VOCs) that can release harmful gases into the air, impacting indoor air quality.
Safer Alternatives:
- Choose low-VOC or eco-friendly screeds.
- Opt for water-based primers and bonding agents instead of solvent-based options.
- Allow proper curing and off-gassing time before installing flooring.
Enhancing Indoor Air Quality with the Right Screed
Choosing the right screeding solution can actively improve air quality. Self-levelling, fibre-reinforced, and polymer-modified screeds tend to produce less dust and contain fewer emissions.
Moisture and Mould Risks
Screeding materials with high moisture content can contribute to dampness, leading to mould growth and poor air quality.
How to Prevent Moisture Issues:
- Use fast-drying or liquid screeds to reduce residual moisture.
- Ensure adequate ventilation during curing.
- Check for moisture barriers in areas prone to dampness.
