Will there be strong odors during epoxy installation?

Managing Epoxy Odor in St. Louis Homes

Odor is a common concern for St. Louis homeowners, especially if the garage shares HVAC with the house or if you’re coating a basement. The good news is that modern professional-grade epoxy systems produce far less odor than older products, and proper ventilation makes a big difference.

What Causes Epoxy Odor?

Epoxy coatings release volatile organic compounds (VOCs) as they cure. These are the chemicals you smell during and immediately after application.

• Older Solvent-Based Epoxies:
  These had strong, lingering odors that could affect the whole house.

• Newer High-Solids and Water-Based Systems:
  These produce significantly less odor and dissipate much faster.

Note: The strongest smell occurs during application and the first few hours of curing. After 24 hours, most odor is gone, though some slight smell may linger for a few days, depending on ventilation and temperature.

• Polyaspartic Coatings:
  These cure so quickly that odor is minimal and clears faster than traditional epoxy.

Managing Ventilation During Installation

Good ventilation is key to keeping odors contained. Here’s how to manage ventilation during installation:

1. Garages:

   • Open doors and windows.

   • Use fans to move air outward.

2. Basements:

   • Use portable ventilation fans.

   • Open windows and exterior doors to prevent odor from spreading through the house.

Seal Epoxy plans ventilation strategies based on the space:

• Garages are straightforward—open doors, and air moves.

• Basements require more care, especially if they’re connected to central air systems.

If you have concerns about the smell affecting the house, mention it during the estimate. Seal Epoxy can:

• Schedule work when you’ll be away for the day.

• Take extra ventilation steps to keep odor out of living areas.

Special Considerations for Basements

1. Basements with Shared HVAC Systems:
   These need extra attention. Seal Epoxy recommends closing vents and sealing doorways during application to prevent fumes from circulating through the house.

2. After 24 Hours of Curing:
   Once the coating has cured for 24 hours, normal ventilation can resume.

Note: Some homeowners with sensitivities to smells choose to stay elsewhere during the first day of curing. This is rarely necessary but can provide peace of mind.
