Can You Sealcoat in Humid or Damp Conditions?
Sealcoating is an essential maintenance step for preserving asphalt surfaces, but many property owners wonder if it can be done when humidity is high or the ground is damp. This article explores the effects of moisture on sealcoating and offers expert insights from Capital Parking Lot Line Painting in Cambridge, Ontario.
Understanding Sealcoating and Its Importance
Sealcoating involves applying a protective layer to asphalt surfaces that helps guard against damage from UV rays, water penetration, and everyday wear and tear. It extends the life of parking lots, driveways, and roadways, making it a cost-effective solution for property maintenance.
Capital Parking Lot Line Painting, based in Cambridge — one of Ontario's top 30 cities — has extensive experience ensuring that sealcoating is done under optimal conditions for maximum durability.
How Humidity and Dampness Affect Sealcoating
The Challenge of Moisture
Sealcoating requires a dry surface for the best adhesion and curing. When asphalt is damp or the air is humid, several issues can arise:
- Delayed Drying: High moisture slows the evaporation of water and solvents in the sealcoat, increasing drying time.
- Poor Adhesion: Moisture creates a barrier between the sealcoat and asphalt, preventing proper bonding.
- Reduced Durability: If sealcoat doesn't bond well, it can peel, crack, or flake prematurely.
Humidity vs. Damp Surfaces
While humidity refers to moisture in the air, dampness relates to moisture on the asphalt itself. Both can impact sealcoating differently:
- High Humidity: Relative humidity above 85% makes sealcoat drying slower but is not always a complete barrier to application.
- Damp Surfaces: Sealcoating on wet or damp asphalt is generally not recommended due to adhesion failure risks.
Best Practices for Sealcoating in Cambridge’s Climate
Cambridge’s climate, characterized by seasonal humidity fluctuations and occasional damp conditions, requires careful planning. Capital Parking Lot Line Painting recommends the following steps to ensure successful sealcoating:
- Check weather forecasts and avoid sealcoating before rain or heavy dew.
- Confirm the asphalt surface is fully dry—no visible moisture or damp spots.
- Opt for early morning or late afternoon applications when humidity tends to be lower.
- Use sealcoat products designed to perform well in variable conditions.
- Allow ample curing time before reopening the area to traffic.
