# Fading colour: warning signs of surface loss

> Uniform grey is cosmetic fade; patchy grey with loose grit is binder loss. The signs that separate a reseal from an overlay, and when fading needs action.

Fading is the most misread symptom in driveway maintenance. Uniform grey on a firm surface is cosmetic and needs a reseal at $0.15 to $0.30 per square foot. Patchy grey with loose grit and exposed aggregate is binder loss, and no coating fixes it. The signs below separate the two.

## What fading looks like at each stage

Stage 1: the surface darkens from black to charcoal, evenly, with no change in texture.

Stage 2: the colour becomes patchy, with lighter areas in the wheel paths and sun-exposed sections.

Stage 3: the surface looks brown-grey, feels gritty, and small stones begin to loosen.

Stage 4: aggregate is clearly exposed, the surface sheds grit, and edges start to crumble.

Stages 1 and 2 are cosmetic. Stage 3 is the boundary. Stage 4 is surface failure.

## The signs, and what each means

| Sign | Appearance | Meaning | Action |
| --- | --- | --- | --- |
| Uniform grey | Even colour, firm surface | Oxidation of the film | Reseal on cycle |
| Patchy grey | Lighter wheel paths | Uneven wear | Reseal, check interval |
| Gritty feel | Sand-like texture | Film thinning | Reseal soon |
| Loose stones | Gravel on the surface | Binder loss | Assess for overlay |
| Exposed aggregate | Visible stone pattern | Surface failure | Overlay likely |
| Fading plus cracks | Grey with connected cracks | Structural issue | Diagnose base |
| Fading plus ponding | Grey with standing water | Drainage failure | Correct grade first |

The last two rows are the ones that change the category from maintenance to repair.

## How to test in three minutes

Run a hand across a dry section. A smooth, slightly waxy feel means the film is intact; a sandy, shedding feel means it is not.

Look at the surface at a low angle in raking light. Exposed aggregate shows as a pebbled pattern; a sound film looks continuous.

Press a screwdriver into the surface between any cracks. Softness means the base is losing support, which is a different problem from fading.

Two of those three pointing to material loss is your answer: the driveway needs more than a coat.

Repeat the test in three places: a wheel path, a shaded section, and an edge. Comparing them tells you whether the wear is concentrated or general, and that in turn tells you whether a patch of the affected area or the whole surface is the job. A single worn wheel path is often the first sign that traffic is heavier than the base was designed for.

## Why fading is patchy

Uneven colour is normal and tells you where the wear is.

Wheel paths lose the film fastest because tires abrade it and because those areas flex most under load.

Sun-exposed sections oxidise faster than shaded ones. A driveway with a house shadow across half of it will often show two distinct colours within a few feet of each other, and the boundary moves with the seasons as the shadow shifts. That is a useful diagnostic: if the line between dark and light follows a shadow, the fade is entirely ultraviolet. If the boundary follows a crack, a drain, or a low spot, water is involved and the surface is failing faster than the sun alone would explain.

Edges fade differently again, because they take water from the lawn and traffic from the turn-in.

Patchiness is not a defect in itself. It becomes significant when the lighter areas also feel gritty, because that means the film is gone rather than merely thin.

## What each sign costs to address

Uniform grey on 600 square feet: reseal at $0.20 per square foot, $120.

Grey with 60 linear feet of cracks: reseal $120 plus crack filling at $3 per foot, $180, total $300.

Grey with exposed aggregate across the surface: overlay at $5 per square foot, $3,000.

Grey with alligator cracking over a quarter of the surface: overlay $3,000, or replacement at $10 per square foot, $6,000.

The step from $120 to $3,000 happens at the point where binder is lost, which is why the texture test matters more than the colour.

## Fading that is a warning, not a cosmetic issue

Four combinations mean the fade is secondary.

Fading with ponding. Water standing a day after rain means the surface is out of plane. Sealing holds water at the low spot and accelerates failure there.

Fading with alligator cracking. The pavement has lost flexibility or the base is moving. A coat re-cracks along the same lines within a season.

Fading with soft spots. The subgrade is saturated and the pavement is deflecting. Nothing applied to the surface fixes it.

Fading with edge crumbling. Water is getting under the pavement at the perimeter, and the failure works inward.

In each case, deal with the structural problem first.

## What to record

A fading inspection is only useful if it produces a baseline.

1. Photograph the driveway from the same spot each year.
2. Note the date of the last sealcoat and the product used.
3. Mark the boundary of any patchy area with chalk and measure it.
4. Record whether the surface sheds grit when rubbed.
5. Note any new cracks, ponding, or soft spots.

Next year's inspection then compares like with like, and a contractor quote has something concrete to work from.

## When to reseal, in one paragraph

Reseal when the surface is uniformly grey, the texture is firm, water soaks in rather than beading, and at least two years have passed since the last coat. Do not reseal when the surface is shedding aggregate, because the coat will not bond. Our [fading colour repair](https://drivewaysealinglab.com/fading-colour-repair/) guide covers the sequence, and [fading colour prevention](https://drivewaysealinglab.com/fading-colour-prevention/) covers the interval that keeps the fade cosmetic.
