1. What is a fog seal?
A fog seal is a thin asphalt pavement treatment applied directly to the surface of an existing asphalt pavement. It penetrates into the pavement surface, helps seal small surface voids and micro-cracks, restores aged asphalt properties, and provides protection against water, oxidation, UV exposure, and other environmental damage.
2. What is Go Green Asphalt Fog Seal used for?
Go Green Asphalt Fog Seal is mainly used for preventive maintenance and rejuvenation of aging asphalt pavements. It is suitable for roads showing signs of oxidation, surface aging, minor cracking, porosity, or loss of asphalt binder. It can also restore the pavement's dark, fresh appearance.
3. Can fog seal repair asphalt cracks?
Yes. Go Green Eco-friendly Asphalt Sealer can help seal hairline and surface cracks up to approximately 3 mm wide. For wider or more severe cracks, dedicated crack repair materials should be used before applying the fog seal.
4. How much fog seal do I need per square meter?
For Go Green Eco-friendly Asphalt Sealer, the recommended application rate is approximately 0.2–0.4 kg/m² in one coat. For sand mix sealer, the recommended application rate of approximately 1.0–1.5 kg/m². The actual consumption may vary depending on pavement condition, surface porosity, and application method.
5. How is asphalt fog seal applied?
Go Green Asphalt Sealer is a ready-to-use material. It can be applied by spraying, sweeping, or brushing. For large road projects, a heavy-duty commercial or high-pressure airless sprayer is recommended for efficient and uniform application.
6. How should the asphalt surface be prepared before fog sealing?
The pavement should be clean, dry, and structurally sound before application. Dust, loose particles, debris, and other contaminants should be removed to open the surface pores and improve penetration. Compressed air or mechanical brushing can be used for surface cleaning.
7. How long does it take for fog seal to dry?
Under suitable construction conditions, Go Green Asphalt Sealer can dry relatively quickly. The treated pavement can generally be opened to traffic in approximately 2–3 hours, depending on weather, temperature, humidity, pavement condition, and application rate.
8. Does fog seal make asphalt pavement waterproof?
Fog seal helps reduce surface permeability by sealing pores and small surface defects, providing improved resistance to water and moisture penetration. This can help protect asphalt pavement from water-related deterioration and environmental damage.
9. Can fog seal be used on highways and parking lots?
Yes. Go Green Asphalt Sealer can be used for various asphalt pavement applications, including highways, city roads, parking lots, bridges, tunnels, and other asphalt surfaces requiring preventive maintenance.
10. What is the difference between fog sealer and sand mix sealer?
A conventional fog seal is a thin treatment mainly designed to penetrate and seal the asphalt surface while rejuvenating aged binder. Go Green Sand Mix Driveway Sealer incorporates fine sand to provide additional surface texture and skid resistance and is recommended at a higher application rate of approximately 1.0–1.5 kg/m².
11. Can fog seal restore the appearance of old asphalt?
Yes. Go Green Eco-friendly Asphalt Sealer is designed to restore the pavement's deep matte black appearance while helping rejuvenate aged asphalt. It is particularly suitable for asphalt surfaces that have become faded, oxidized, or weathered over time.
12. How often should asphalt pavement be treated with fog seal?
The treatment frequency depends on pavement age, traffic loading, climate, surface condition, and previous maintenance history. Fog sealing is generally used as a preventive maintenance treatment, so it is best applied before significant pavement deterioration occurs rather than waiting until major cracking or potholes develop.
13. Can fog seal be applied to an old asphalt pavement?
Yes. Fog seal is particularly suitable for aging asphalt pavement with oxidation, minor surface cracking, porosity, or loss of asphalt binder. By penetrating the surface and helping restore aged asphalt properties, it can extend the useful service life of pavement and delay more expensive rehabilitation.
14. Is Go Green Asphalt Sealer suitable for large-scale road projects?
Yes. The product can be applied using professional spraying equipment, with a recommended working speed of approximately 300–500 m²/hour. This makes it suitable for large-scale applications such as highways, municipal roads, and other extensive asphalt pavement maintenance projects.
15. Why should I choose fog seal instead of resurfacing?
Fog sealing is a preventive maintenance treatment rather than a replacement for structural rehabilitation. When asphalt pavement is still structurally sound but beginning to show aging, oxidation, minor cracking, or surface deterioration, fog sealing can provide a cost-effective way to protect and rejuvenate the pavement before more extensive and expensive repairs are required.
