Sealcoating FAQs

A blacktop is a porous surface that can absorb water. When water that has been absorbed by your blacktop freezes and thaws, it can harm your blacktop. Sealcoating the surface delays the process, so your blacktop will last longer, saving you money.

We recommend you fill cracks and sealcoat your blacktop after one year. Cracks should be routed and filled yearly, and sealcoating should be done every third year.

To ensure a long-lasting blacktop, sealcoat it every three years and have cracks routed and filled every year. You should also

• Keep it clean.
• Keep trees away. (Shade creates harsh conditions.)
• Avoid parking in the same spot daily.
• Don't turn the steering wheel unless your vehicle is moving.
• Don't drive near the edges.
• Keep heavy vehicles and equipment off the blacktop.

As long as there is no frost, crack filling can be done anytime. Cool temperatures in the spring and fall make crack filling easier because the cracks naturally expand in colder weather. Sealcoating can be done when the blacktop is 50°F or more and will remain that warm overnight.

Cracks don't always form a clean, solid break. Routing opens the crack, creating a larger void for the hot, rubberized filler to adhere to the edges and seal the crack fully. If cracks are not routed, water can leak in and cause the deterioration of the base material.
