See the difference: No "Coal Tar" Smell
Eco-Friendly: Non-toxic, non-hazardous, and non-flammable. It is water-based and has a unique "sweet" scent from the soybean oils.
Safe for Families and Pets: You don't have to worry about harsh chemical runoff into your lawn or "tracking" coal tar toxins into your home on shoes or paws. It lacks the skin-irritating chemicals found in traditional refined tar sealers
Appearance: Provides a deep "jet black" finish. Because it is UV resistant, it tends to hold its dark color longer than standard sealers.
Drying Time: Once applied, the product dries relatively fast compared to traditional sealers:
- Tack-free: Approximately 75 minutes.
- Foot Traffic: Safe after 4–6 hours.
- Vehicle Traffic: Wait 24–48 hours before driving on the surface.
- Weather: Do not apply if rain is expected within 24 hours or if temperatures are below 40°F (4°C).

Conditioner: It acts as a penetrant that helps rejuvenate and soften old, dried-out asphalt rather than just sitting on top.
Protection: Highly resistant to
UV rays, gasoline, and motor fluids. It is specifically designed not to crack or peel like thicker, traditional coatings.


Ease of Maintenance:
Once sealed, the surface becomes much smoother and less porous.
This makes it:
- Easier to sweep or blow off debris.
- Easier to clear snow and ice, as the dark color absorbs heat and the sealer prevents ice from "rooting" into the asphalt pores.
- Extends Lifespan: Generally lasts 7-10 years depending on traffic volume and environmental conditions.
Note: This Not a Filler: This product is a sealer/conditioner, not a crack filler. You must repair all potholes and cracks before the application.
7 Signs Your Driveway Needs Sealcoating
DIAGNOSIS 101
- Appearance: If your driveway looks more like concrete than asphalt, it has lost its flexible binders and is becoming brittle.
- Hairline Cracks (spider webbing): These occur when the asphalt dries out and can no longer expand and contract with temperature changes.
- Raveling or Loose Gravel: This means the "glue" holding the rocks in place has worn away. A penetrant like Bio Blacktop helps re-bond these particles.
- Water "Soaking In" instead of Beading: The porous surface is wide open to water damage and freeze-thaw cycles.
- Stains from Oil and Gas: If you see dark, soft spots caused by oil or gasoline leaks, the chemicals are actively eating through the asphalt binder. Because Deco Bio is highly resistant to gas and motor fluids, applying it creates a shield that prevents these fluids from dissolving your driveway.
- Potholes: While a sealer is not a filler for large holes, the appearance of potholes is the final "cry for help" from your driveway.
- Deep Cracks: If you see deep cracks (wider than 1/4 inch), you need to repair them immediately and follow up with a seal coat to prevent the surrounding area from suffering the same fate.
Pro Tip: If you aren't sure, try the "Water Test."
Pour a bucket of water on a dry section of your driveway. If the asphalt turns dark and the water disappears into the surface within a minute, your protective layer is gone. Seal it before the real damage hits.
