How to Make Colored Asphalt Driveway Sealers How to Make Colored Asphalt Driveway Sealers

What You'll Need
Colored sealer additive
Agitator
Asphalt sealer
Silica
Water

Whenever you have to lay asphalt, you need to protect it with asphalt driveway sealers. If you fail to use asphalt driveway sealers, it can lead to the asphalt cracking and breaking off. This can occur due to pressure on the asphalt as well as weather. City streets are an example of what happens when asphalt sealers are neglected. You wind up with potholes and cracks that need to be filled and patched. Black and clear are the standard colors when dealing with asphalt driveway sealers, but this does not have to be the case. You do not have to be limited to one color for your driveway sealer, as you can color it, and the following article will show you how.

Step 1 – Formula

Mixing asphalt driveway sealers is a process that is trial and error. When you add something, you need to take something away. The colored sealer additive is roughly 12-percent of the total formula for the sealer. This can increase depending on desired brightness. The original formula given on the sealer doesn’t account for the addition of color.

Step 2 – Color to Water

The color product should be mixed with the water before you do anything else with it. Typically, you would use 38 gallons of seal coat with the color additive. Make sure the agitator is running, as this is the only way you will get a proper and even mixing. Use half of the water required for the sealer and add the color to the water. A typical mixture is 38 gallons of sealer to 10 gallons of water. This can and will vary from product to product. Now, add the color to this mixture. The agitator must be running. Add the color slowly and allow the agitator to run for about 20 minutes to achieve evenness.

Step 3 – Check Viscosity

Asphalt driveway sealers have to be a certain thickness in order to properly seal asphalt. A good rule of thumb is that it should be about the same viscosity as cold maple syrup. You used 5 gallons of water in Step 2, and here you will be adding the remaining 5 gallons. You may use more or you may use less. What is important is the viscosity of the product. Slowly pour the water into the agitator and allow it to be fully incorporated with each addition before adding more.

Step 4 – Silica

Silica is a fancy word for sand. The silica is used to help strengthen the asphalt as well as to provide surface grip to prevent skidding. All asphalt driveway sealers have silica added to them for this reason. Good asphalt driveway sealers will not have more than 10-percent silica. This is roughly 1 pound of silica for every gallon of sealer. If a courser surface is wanted, then use a larger grain of silica, such as 30 mesh.
