STEP 1 : POWER WASH THE SURFACE

We like to use a surface cleaner to make the job go faster. The soap helps you know which areas are clean. If the soap is still turning black during your cleaning, its a good bet you have some more power washing to do.

 

STEP 2: FINAL RINSE

A great method to limit the amount of time spent prepping the surface is to use an edge trimmer around landscaping before starting your project.

 

STEP 3: PREPARE THE SEAL COAT

Make sure to mix your product well and to follow the manufacturers recommendation on when to apply. Some sealcoat products can only be applied with another chemical mixture or during certain temperature ranges.

 

STEP 4: APPLY THE COATING

Make sure to wait till the driveway is dry so you know which areas you’ve missed! Apply the chemical uniformly and as thick as the manufacturer recommends.
