Frequently Asked Questions

We at Onyx Asphalt recommend sealcoating every 2-5 years to protect your asphalt and prolong it's lifespan. It may seem like a lot, but maintaining your driveway will preserve it and make it last.

We recommend that customers let their sealcoat driveway dry for 36-48 hours, as to prevent any damages from occurring on your fresh coating.

If the job is done right, it takes only one good coating to look great and provide protection for your asphalt.

The best weather for sealcoating is when the sun is shining! We use an oil-based sealer that is best when applied to a dry surface.

There's no need to! When you hire Onyx Asphalt, we do all the work for you which includes pressure washing prior to sealcoating.

Although it may sound like a good way to save, sealing your own driveway using store bought products actually does more harm than good to your asphalt surfaces. We recommend hiring the experts that use the highest quality sealer specifically suited for the harsh Alaskan weather as to prolong the lifespan of your asphalt.

The GSB-78 oil-based sealant can last 2-5 years, depending on wear and tear your asphalt faces. Crack sealing lasts 1-2 years as it is a rubberized asphalt that is meant to flex with the asphalt, weather and wear and tear will cause crack sealant to erode more quickly.
