Epoxy floors are admired for their sleek finish, durability, and ability to transform dull concrete into a resilient, polished surface. However, one of the common concerns homeowners and businesses raise is related to outgassing and lingering odours during installation. With the rise in demand for Epoxy Flooring in Sydney, it’s important to separate fact from myth and understand how these issues occur, and more importantly, how they can be prevented. At City 2 Coast Epoxy Flooring, we prioritise not just beautiful results, but also safe, well-prepared installations that minimise odour and eliminate the risk of bubbling caused by outgassing.
What is Outgassing in Epoxy Floors?
Outgassing happens when air trapped inside a concrete slab escapes upwards through the surface during the curing of epoxy. As the epoxy resin begins to harden, these air bubbles can create pinholes, blisters, or small craters in the finished floor. The result is a less-than-perfect finish that undermines both the appearance and the performance of the floor.
With professional Epoxy Flooring in Sydney, outgassing is not an unavoidable problem. Instead, it’s a sign that the surface preparation was not handled correctly. City 2 Coast Epoxy Flooring takes extra steps to properly prepare concrete surfaces, sealing pores and ensuring that the substrate is stable before any coating is applied.
Understanding Odour During Installation
The second issue often associated with epoxy floors is the odour released during application. Epoxy resins contain volatile organic compounds (VOCs), which are responsible for the strong smell. These odours can linger during the curing process, leading to discomfort for occupants if not managed properly.
The good news is that with advancements in epoxy formulations and proper ventilation techniques, odour can be significantly reduced. Many modern epoxy systems used by City 2 Coast Epoxy Flooring are low-VOC or virtually odour-free, making them far more suitable for residential and commercial applications across Sydney.
Can Outgassing Be Prevented?
Yes — outgassing can absolutely be prevented with proper techniques. The most common cause is applying epoxy to warm or porous concrete without sealing. When concrete warms up, trapped air expands and escapes, creating bubbles. To combat this, City 2 Coast Epoxy Flooring applies primers and seal coats that block air release before the final epoxy layers are poured.
Additionally, timing is everything. Applying epoxy when temperatures are stable — rather than during the heat of the day — helps prevent trapped air from escaping through the coating. This attention to detail is what separates professional installations from rushed or DIY attempts.
How to Minimise Odour Exposure
Managing odour during epoxy installation is all about product selection and ventilation. City 2 Coast Epoxy Flooring uses high-quality, low-VOC epoxy products that drastically reduce harsh smells. During installation, proper airflow and protective equipment are used to ensure the environment remains safe for both installers and property owners.
In most cases, odour is strongest only during application and dissipates quickly once the floor begins curing. Within 24–48 hours, the smell is minimal, and the space is safe to use again. For commercial or industrial clients concerned about downtime, we carefully plan projects to align with operating schedules, ensuring minimal disruption.
Why Professional Application Matters
Outgassing and odour issues often occur when epoxy is applied without sufficient preparation or when low-quality products are used. DIY epoxy kits or budget contractors often skip essential steps like moisture testing, proper priming, or the use of low-VOC systems.
By choosing Epoxy Flooring in Sydney from experts like City 2 Coast Epoxy Flooring, you’re investing in a team that understands the science behind epoxy. From moisture management to substrate sealing and ventilation, every step is executed with precision, ensuring a flawless, odour-controlled outcome.

They provide a long-lasting, chemical-resistant, and easy-to-maintain surface that adds value to both residential and commercial spaces.
