What rejuvenators actually do
Bitumen ages by losing its volatile maltene fraction — the lighter oils that keep it flexible. A rejuvenator is a maltene-rich product that penetrates the surface, replaces those oils, and softens the binder back toward its as-new state.
Rejuvenator vs sealcoat
| Sealcoat | Rejuvenator | |
|---|---|---|
| Action | Sits on top, protects from UV | Penetrates, restores binder |
| Best timing | Every 3–5 years | Years 3–8 from new |
| Repairs cracking? | No | Slows progression of fine cracking |
| Appearance | Deep matt black | Subtle darkening |
| Cost | Moderate | Moderate |
When to rejuvenate
- Driveway is 3–8 years old
- Surface is greying but largely uncracked
- You want maximum life from the existing asphalt
Application
- Pressure wash and dry the surface.
- Apply the rejuvenator with a low-pressure sprayer at the rate on the data sheet.
- Allow penetration time per the product (usually 1–2 hours).
- Sand any pooled product if it doesn't fully penetrate.
- Keep off for 24 hours.
Stacking treatments
Crack-seal first, then rejuvenate, then sealcoat after the rejuvenator has fully cured (usually 30 days). Done in that order, each layer reinforces the others.

Frequently asked questions
Will a rejuvenator fix existing cracks?
No — it slows the rate at which fine cracks widen, but visible cracks still need to be sealed first.
How long does a rejuvenator last?
Most penetrating rejuvenators give 3–5 years of binder restoration before the cycle is worth repeating.
Is a rejuvenator a substitute for sealcoating?
No — they do different things. Rejuvenator restores the binder from within; sealcoat protects the surface from above.
