Key Considerations Before Covering Asbestos Tiles
When contemplating whether to put flooring over asbestos tiles, several factors must be considered:
Condition of the Asbestos Tiles
The condition of the asbestos floor tiles is paramount. If the tiles are intact without cracks or damage, you are more likely safe to cover them. However, if they are deteriorating, there is a risk of releasing harmful fibres into the air. A professional assessment is advisable, as disturbing the tiles during installation poses a significant risk.
Type of Flooring to Use
Certain types of flooring are more suitable for installation over asbestos than others. For instance, floating floors, such as laminate or engineered wood, can be an effective option. They don’t require adhesive, which minimises the risk of disrupting asbestos fibres. On the other hand, glue-down flooring may exacerbate the risks if the tiles are disturbed during the application.
Ventilation and Air Quality
Regardless of whether you decide to put flooring over asbestos tiles, maintaining adequate ventilation is crucial. Ensure that your workspace is well-ventilated during the installation process. Using air purifiers can also help improve indoor air quality, reducing the potential for fibres becoming airborne.
Best Practices for Flooring Over Asbestos Tiles
Here are some best practices to follow if you decide to proceed with putting new flooring over asbestos floor tiles:
Use Proper Tools and Materials
If you choose to handle the installation yourself, ensure you are equipped with the right tools and protective gear. Using tools that minimise dust generation (like a flooring nailer) can further reduce risks. Avoid using saws whenever possible, as they can create dust that might contain asbestos.
Seal the Asbestos Tiles
Before laying down new flooring, consider sealing the existing asbestos floor tiles with a compatible sealant. This will provide an added layer of protection and trap any potential fibres, making it safer to install new flooring on top.
What to Avoid When Dealing with Asbestos Tiles
While it is possible to cover over asbestos floor tiles safely, there are crucial actions to avoid:
- Do Not Remove: Unless absolutely necessary and performed by professionals, avoid removing existing asbestos flooring. The removal process can pose more health risks than leaving them undisturbed.
- Avoid Disturbance: During installation, take care not to disturb the tiles. Not only can this release fibres, but it can also compromise the structural integrity of the new flooring.
- Ignore Local Regulations: Be mindful of local regulations concerning asbestos management. Some jurisdictions may have specific guidelines on how to handle asbestos-containing materials, including flooring.
Final Thoughts
In summary, while it is generally safe to put flooring over asbestos floor tiles if done properly, caution and professional guidance are paramount. Assess the condition of the existing tiles, choose your new flooring wisely, and always prioritise safety steps during installation. Ultimately, with the right knowledge and practices, you can successfully refresh your flooring without compromising your health or safety. If in doubt, consult with a qualified professional to make the best decision for your specific situation.
