Why Asphalt Driveways Don't Last

The science behind asphalt deterioration and how rejuvenation extends pavement life by decades.

Sprayer & Equipment Guide

HawkSeale is shipped as a concentrate. Mix 1 gallon HS concentrate to 9 gallons water (can be adjusted 5% leaner or richer). Expensive equipment is not required.

Millings Rejuvenator (Glue)

Re-bonds recycled asphalt millings (RAP) into a hard, durable, snow-plowable surface. Requires high-volume application — think soaking rain, not a sprinkle.

Rate: ~1 gallon solution per sq/yd
Applied in 3 coats to the point of puddling.

Preservative Sealer (Existing Asphalt)

Penetrates existing asphalt pavement to fill cracks, voids, and fissures from the bottom up — blocking air and moisture that cause deterioration.

Rate: 0.35–0.42 gal solution per sq/yd
Applied in 3 coats. Can use roller or sprayer.

Small Projects

2-gallon sprinkle can — drill 1/8" holes vertically in the spout for a fan-like spray. Works for both millings and existing asphalt
Heavy-knap paint roller — for existing asphalt sealing on small areas (driveways, patching)
12V 5.5 GPM RV pump + garden hose + lever shut-off wand — ~$100-150 total, auto pressure shut-off. Supplies a 4-ft boom with 4 tips

Warning

Lawn sprayers and backpack sprayers are NOT recommended for millings. They do not provide sufficient volume to saturate millings to the required 2-3" depth. Think of a good soaking rain vs. a sprinkle — millings need volume.

Backpack/lawn sprayers can work for existing asphalt sealing where less volume is needed.

Medium & Large Projects

12V 5.5 GPM pump + 4-ft boom (4 tips) — medium driveways and parking areas. Use 80-20 fan jet nozzles (80° fan, 2 GPM each)
12V 7.0 GPM pump + 6-ft boom (6 tips) — larger projects. Also doubles as concentrate transfer pump
1" or 2" trash pump + large boom (80-50 tips) — commercial and municipal scale. Run at slowest adequate speed
Skid/trailer-mounted tank (100-200+ gal) — mount in truck bed, UTV, or trailer for mobility

Nozzle & Pump Notes

Use 80-20 fan jet nozzles (80° fan, 2 GPM) for booms. Avoid pistol-style wands — HS adhesive will cause them to stick open. Do not use impeller/gear pumps for mixed solution (causes separation/gelling). Roller pumps will not work.

Application showing sealed vs untreated surface

Millings Application (3-Coat Process)

Prep: Spread and grade millings to minimum 2" depth (3-4" recommended). Expect ~30% compaction. Depths over 4" should be done in lifts/layers.

1st coat: Apply to the point of puddling — absorbs ~½ gallon per sq/yd.

2nd coat: Apply as soon as previous coat absorbs. Takes less solution as millings saturate.

3rd coat: Apply remaining balance to reach ~1 gallon total per sq/yd. Rate is self-determining — areas needing more will absorb more.

Compact: Begin as soon as solution absorbs or within 4 hours. Use 5,000# or heavier ride-on roller or vibrating plate compactor. 4-6 passes is usually adequate. DO NOT vibrate after initial compaction — this damages the adhesion and re-bonding process.

Curing: 2-10 days at 65-85°F. Light straight traffic can begin immediately. Avoid turning traffic, overnight parking, ATVs, and heavy trucks until fully cured. Temps above 90°F with high humidity or below 60°F can extend cure to 2-4 weeks.

Existing Asphalt Application (Preservative Sealer)

Apply in 3 coats totaling 0.35-0.42 gallons per sq/yd. First coat absorbs about half; each successive coat absorbs less until run-off.

Very porous pavements may need more than 3 coats. Cracks wider than ¼" should be filled first. Clean surface of debris before application.

Can be applied with a sprayer, foam roller, or heavy-knap paint roller.

Traffic can begin as soon as the surface is dry (usually a few hours). Avoid tracking wet product onto other surfaces.

General Best Practices

Temperature: Do not apply below 55°F ground temperature or if freezing risk within 72 hours. Ideal range is 65-85°F. Temps over 90°F with high humidity slow curing significantly.

Mixing: 1 gallon concentrate to 9 gallons water. Stir gently — do NOT whip or aggressively mix. Can adjust 5% leaner or richer. Do not over-dilute.

Cleanup: Rinse all pumps and equipment with water immediately after use. HS will leave residue inside tanks and hoses. For skin/clothing: WD-40, diesel, or ZEP Degreaser. Hair conditioner works for hands.

Storage: Cool, dry area. Avoid freezing and direct sun. Use within 3-6 months.

Water beading on HawkSeale-treated surface

The Water Test

This simple demonstration shows why HawkSeale works and why conventional sealers fail. Pour water on an untreated asphalt surface and it sits on top, slowly seeping into cracks where it freezes, expands, and destroys the pavement from within.

Now pour water on a HawkSeale-treated surface. The water beads up and rolls off. The product has penetrated deep into the pavement, filling the fissures and voids from the bottom up — blocking the two main causes of asphalt deterioration: air and moisture.

This is the difference between a surface coating that sits on top and peels off, and a penetrating rejuvenator that restores the binder chemistry from within. HawkSeale doesn't just cover the problem — it solves it.

Try It Yourself

Apply HawkSeale to a small test section, let it cure for 24 hours, then pour a glass of water. You'll see the difference immediately. We encourage every customer to do this test before scaling to their full project.

Results by the Numbers

Real savings from real projects across the country.

40-60%

Savings vs. Hot Mix Asphalt

HawkSeale-treated millings consistently deliver 40-60% cost savings compared to traditional hot mix paving for driveways, parking lots, and roads.

20+ Years

No Failures

First streets sealed with HawkSeale are now over 20 years old with zero deterioration. Preventative maintenance beats costly corrective maintenance every time.

More Pavement Preserved

Cities can seal and preserve five times the pavement area compared to the cost of a single overlay. Stretch your budget further with preventative sealing.

The Science Behind 25 Years of Results

HawkSeale has been developed and improved over a 25-year span with the assistance of the best asphalt scientists in the industry. The formula uses proprietary copolymers and resins that penetrate deep into the asphalt matrix, rejuvenating the bitumen binder at a molecular level.

Unlike surface coatings that sit on top and peel off within a few years, HawkSeale fills fissures and voids from the bottom up, blocking air and moisture — the two primary causes of asphalt deterioration. This prevents freeze-thaw cycle damage that destroys untreated pavement.

The result is a hard, durable, snow-plowable surface that can be applied to both compacted and un-compacted millings, and works equally well as a preservative sealer for existing asphalt pavement.
