The rules this check uses

This table is the whole Fayetteville check: pail-consensus thresholds, the rising-trend requirement, and a 36-hour cure standing in for the labels' 24–48 spread.

Typical label thresholds for driveway sealing — the ruleset behind every Fayetteville verdict above.
CheckThresholdWhy it matters
Air temperature 55–90°F, and rising Checked across the working day, 8 a.m.–6 p.m., against Fayetteville's hourly forecast — not just the daily high.
Overnight low ≥50°F during the first 24 h The engine reads every overnight hour in the cure window, not just Fayetteville's forecast low.
Dry before ≤0.05" rain in the prior 24 h Asphalt must be fully dry; sealer will not bond to damp pavement.
Dry after <0.05" rain for 36 h after (48 h cool or shaded driveways want 48 h) Most sealers list 24–48 dry hours; this site checks 36.
Evening dew-point spread ≥5°F from 6–11 pm Scored on the worst hour between 6 and 11 p.m., when surfaces cool past the air.
Daytime humidity ≤85% Water-based sealer dries by evaporation; humid air stalls it.
Wind ≤20 mph (dust and debris in wet sealer up to 28 mph) Wind wrecks application first (drift, lap marks) and carries debris into wet work second.

Always follow your product label — formulas vary. These rows are the industry-typical range; the can in your Fayetteville garage is the contract.

Figure 123 workable days a year in Fayetteville, spread across May through September. Shoulder months turn on the overnight rule: an afternoon at 76°F passes, but the 50°F night floor is what actually opens the season in May.

Pouring before you seal? Concrete in Fayetteville trades the pavement-warmth rule for a 48-hour freeze watch.

Fayetteville by the numbers

Prep checklist

  1. Wait for a rising pair: 55°F+ and climbing, first night over 50°F, 36 dry hours — in Fayetteville that pattern lives May through September.
  2. Run crack filler the previous afternoon — filler needs its own skin time before topcoating.
  3. Sweep to bare asphalt and kill the oil spots first — emulsion won't bond through either.
  4. Check yesterday, not just today: 24 h under 0.05" of rain. Fayetteville's December makes that nearly automatic at 20% rain-day odds.
  5. Tape the garage slab and sidewalk lines with edging tape — drips on concrete are forever.
  6. Pull thin passes with a squeegee/brush combo, back-brushing the texture as you go.
  7. Start early at the top of the slope: a August morning coat gets the whole 89°F afternoon to break before dew.
  8. Keep tires off through the full cure — with August nights at 68°F, shaded strips need the long end of 24–48 h.

FAQ

What temperature do you need to seal a driveway?

55–90°F and rising, with the first night at 50°F or better. The 'rising' part is why Fayetteville's May start matters: sealing on the front of a warm spell, not the back. Pavement lags air — a shaded slab can fail a passing afternoon.

How long after rain can I sealcoat?

24 hours after the last 0.05"+ rain, and only once cracks and shade strips are visibly dry — asphalt pores hold water after the surface grays out. In Fayetteville's May (34% rain days) that lookback eats most of the calendar; December barely notices it.

How long does driveway sealer take to dry before rain or cars?

Plan 36 rain-free, car-free hours (labels range 24–48; shade and cool nights need the long end). A 0.05"+ shower inside the window streaks the coat gray. December is Fayetteville's easiest month to find that window; May the hardest.

Can you seal a driveway in the fall?

Yes, until the nights quit. The 50°F overnight rule closes Fayetteville's season after September; the classic October mistake is a 62°F Saturday over a 41°F night. Spring restarts around May when pavement warms.

How often should a driveway be sealed?

When the surface tells you: graying, no beading, spreading hairlines — typically every 2–4 years. In Fayetteville, seal before the freeze-thaw season; January averages 27°F nights that pry open every unfilled crack. Fresh asphalt waits 6–12 months.

Best month to seal a driveway in AR?

August tops Fayetteville's table at 24 days clearing the 55–90°F-rising, 50°F-night, 36-dry-hour stack; August and July together carry the season. Check the AR state page for how the ranking shifts across the state.
