WHAT IS A FOG SEAL?
A fog seal is the diluted and slow setting asphalt emulsion, which has been applied lightly to an older pavement.
These are popular because they are not expensive and can bring back flexibility to a paved area. They may even be able to help put off the necessity for further treatments or overlays.
WHO CAN APPLY A FOG SEAL?
Any good asphalt paving company, like the ones from https://www.SaveOnPaving.com, should be able to apply a fog seal for your pavement or project.
WHAT CAN A FOG SEAL ACHIEVE?
The main reason that customers choose a fog seal is to give a new lease of life or rejuvenate an old road surface. If it works, you may be able to delay another overlay going on the road for a couple of years.
HOW LONG WILL IT TAKE?
A fog seal is best for roads which are not super busy and can be closed for up to six hours, whilst the seal has chance to set.
ARE THERE ANY DISADVANTAGES OF A FOG SEAL?
If you over apply a fog seal, then there is the chance of a very thin asphalt layer forming on top of the original road surface.
This may be too smooth and cause problems with skidding. Therefore, sand should be used to help in cases when a fog seal has been over applied.
WHY FOG SEAL IS GOOD FOR CHIP SEAL ROADS
Fog sealing could help prolong the life of chip sealed roads by a year at least.
They can also help prevent callouts from motorists for things like windshield cracks.
FOG SEALING CAN HELP WITH STRIPING
Line striping is also well served by the use of fog sealing.
Because the fog sealant leaves the road looking as if it has been overlaid with asphalt, it provides a fuller contrast with the road markings.
You may find that your road maintenance budget reduces when it comes to re painting lines on a fog sealed road.
FOG SEALING IS BETTER IN EXTREME WEATHER
Fog sealing a pavement or road can help make it safer in extreme weather conditions.
In winter, snow and ice will melt faster, because now the road surface heats up quicker. This makes the road safer to travel on.
FOG SEALING CAN WATERPROOF A ROAD
A fog seal can also help to stop water leaking inside the road, which then causes it to degrade.
FOG SEALING WORKS BEST ON A COARSE SURFACE
A fog sealant is the application of an asphalt emulsion which is sprayed onto a road, sometimes with a sand cover, but not always.
Because it is so smooth, it works well on a coarse surface such as a chip seal.
WHAT EQUIPMENT IS NEEDED FOR FOG SEALING?
You will require a truck for spraying the asphalt emulsion with. And if you are going to use sand in your application, then you will also need a sand spreader.
For fog sealing a chip sealed surface then you will have to broom the extra chips before you apply.
WHAT ARE THE BEST CONDITIONS FOR LAYING A FOG SEAL?
The best conditions for laying your fog sealing are dry and warm days.
It is preferable if the sun is shining and even a light breeze will help set the emulsion.
WHY ELSE MIGHT I CHOOSE A FOG SEALANT?
A fog seal makes a cheap solution to preserving the lifespan of your road or pavement.
It can help prevent raveling and stop it getting worse. However, it is more of a prevention than a cure – the road should be in a good condition to begin with, or it will not help.
