What is the water dilution ratio of asphalt sealer? Why is this important?

Asphalt sealer is a water-based product that must be dilution before it was be spread properly. The material is diluted to a ratio of between 4-5 parts sealer to 1 part water. We keep detailed daily logs of our mixing ratios to ensure a quality finished product for the customer. Please ask our Project Manager if you would like to see the logs associated with your job. If the product is too heavily diluted, it will not provide a quality, long-lasting seal. Putting water on your pavement will not protect it.
