Introduction
Every surface, no matter how expertly laid, will eventually show signs of wear due to traffic, weather, and general use. However, with the right maintenance approach, the lifespan of asphalt and bitumen surfaces can be significantly extended—delaying the need for major resurfacing or costly reconstruction. One of the most effective methods is spray and seal treatment.
At Morayfield Surfacing Solutions in Morayfield, QLD, we apply spray and seal techniques tailored to local conditions. In this article, we explain how spray and seal works, why it’s so effective, and how it can keep your existing surfaces in better condition for longer.
What Is Spray & Seal?
Spray and seal is a two-coat bitumen surface treatment commonly used to preserve and enhance aged or lightly worn pavements. The process involves:
- Spraying a layer of hot bitumen over the surface
- Spreading an aggregate (stone) layer immediately after
- Rolling the aggregate into the bitumen to ensure proper embedding
- Optional second coat for increased durability (double/double seal)
This treatment rejuvenates the surface by resealing it, reducing permeability, and restoring grip.
Key Benefits of Spray & Seal for Existing Surfaces
Moisture Protection
Water infiltration is one of the primary causes of surface deterioration. It seeps through cracks and weak points, softening the underlying base and leading to potholes or collapse.
Spray and seal provides:
- A fresh waterproof barrier
- Protection against rain, runoff, and pooling
- Reduction in freeze-thaw damage (especially inland areas)
Renewed Surface Texture
As bitumen ages, its surface becomes polished, especially in high-traffic areas. This reduces skid resistance and increases the risk of slipping—especially during wet conditions.
Spray and seal helps by:
- Restoring surface roughness
- Improving tyre grip and traction
- Making driveways, roads, and car parks safer
Slowing Oxidation
Bitumen is vulnerable to oxidation under prolonged UV exposure, especially in Queensland’s harsh sun. Oxidised surfaces become brittle and prone to cracking.
Benefits of sealing include:
- UV shielding from direct exposure
- Slowing down surface brittleness
- Minimising crack formation
Cost-Effective Life Extension
Rather than waiting for total failure and incurring full resurfacing costs, a well-timed spray and seal offers:
- A longer-lasting surface at a fraction of the cost
- Reduced need for patching or reconstruction
- Greater value from the original surfacing investment
Spray and seal extends surface performance and saves money in the long run.
When Should Spray & Seal Be Applied?
Timing is key. The earlier spray and seal is applied in the ageing cycle, the more effective it will be.
Ideal scenarios include:
- Asphalt surfaces that are still structurally sound but losing texture
- Bitumen pavements with light oxidation or weathering
- Areas starting to show minor cracks or aggregate loss
- Surfaces 5–10 years old that haven’t yet had a rejuvenation treatment
Surfaces That Benefit Most
Spray and seal is suitable for a variety of settings:
- Residential driveways
- Private access roads
- Car parks and industrial yards
- Rural properties and unsealed roads
At Morayfield Surfacing Solutions, we assess each site’s condition and tailor the treatment to suit local traffic demands, drainage patterns, and surfacing materials.
Maintenance Tips After Spray & Seal
To make the most of a freshly sealed surface:
- Avoid heavy traffic until curing is complete
- Sweep loose stones in the first few weeks if necessary
- Monitor for any early signs of edge or joint wear
- Schedule future sealing based on traffic volume and weathering rate
Regular inspections and prompt patching can further extend the life of your sealed surface.
