Wet & Forget: Your Perfect Helper for Seal Coating Your Driveway

Wet & Forget: Your Perfect Helper for Seal Coating Your Driveway

Whether your driveway is concrete or asphalt, regular seal coating will help it last longer and provide an eye-pleasing complement to your home’s landscaping. A little elbow grease now and then pays off, because seal coating limits a lot of the wear-and-tear your driveway suffers with the of the changing seasons.

Landscaping expert David Beaulieu recommends seal coating asphalt yearly in colder climates, and concrete every three to five years. But watch out: If your driveway is stained with moss, algae, mold or lichen, the sealant you’ve bought won’t adhere properly to your driveway’s surface.

Instead of a well-protected driveway, you could end up with an expensive, time-consuming mess.

If your driveway has moss, mold, mildew, algae or lichen growth, treat the surface with Wet & Forget before you seal coat it. Just saturate the surface and forget about it!

There is no need to scrub, because Wet & Forget will do the work for you. As soon as the growth has disappeared, your driveway will be ready for seal coating.

Algae, Mold or Mildew

“Mold” and “mildew” are both names we use to describe a growth of fungus on a surface. It can look whitish, gray, green or black.

Algae is often slippery, and is usually either green or black. If your driveway suffers from any of these growths, add one part Wet & Forget to five parts water in a pump-up garden sprayer.

Thoroughly saturate the area with the diluted Wet & Forget, and the growth will gradually disappear. If the staining is severe, you can agitate with a brush after application or reapply in one to two months.


Moss is a type of simple plant that is green and velvety, and can cause damage to roof shingles and other surfaces. To remove moss from your driveway, apply Wet & Forget the same way you would to treat algae, mold or mildew.

The Wet & Forget will cause the moss to die and release its grip on the driveway’s surface. Sweep away any remaining moss fragments along with the dirt and other debris as you prepare your driveway for seal coating.


Fungus and algae often grow alone, but they can also grow together and form a separate, unique growth known as lichen. Lichen is crusty or branched, and grows in a wide variety of colors.

Because lichen is a more complex, multi-layered growth, a double-application is most effective for removing it from your driveway. Dilute Wet & Forget as you would for mold or algae.

Saturate the area thoroughly with the diluted Wet & Forget. Wait 15 minutes, then saturate again. Don’t allow the area to dry completely between applications.

This one-two punch will work on both parts of the lichen, which will gradually die and lift away. If any fragments of the lichen remain, sweep them away along with everything else as you clean your driveway prior to seal coating.

Wet It and Forget It! 

Whether you’re applying Wet & Forget to treat moss, mold, lichen or algae, it’s best to apply it on an overcast day so that the sun will not cause the liquid to evaporate too quickly. Also, allow Wet & Forget at least four or five hours to dry before there’s a chance of rain.

Now that Wet & Forget has gotten rid of your moss, mold, lichen or algae problem, you’re ready to prepare the surface for seal coating. Here’s to a long life for your driveway!
