When to seal a crack

Seal cracks as soon as you see them, in dry weather, at 12°C and rising. Cracks up to 9mm take ACF-1 directly; wider or deeper cracks should be packed with sand or backer rod to within 6mm of the surface first. Once a crack has spalled into a hole, switch to Asphalt in a Bag.

Proven on a runway

Southport Flying Club used ACF-1 to seal cracks in their aerodrome runway, applying it with a simple watering can. After a successful test area they moved up to the 19 litre bucket — and Aerodrome Manager Steve Rance says he’d recommend it to anyone with cracked asphalt. Read the testimonial →

Why Asphalt in a Bag

• Permanent. Expands and contracts with the road surface, so the patch moves with the pavement instead of breaking away.
• Cures on impact. Curing is activated by compaction — tamp it or roll it and it sets.
• Bonds to anything. Adheres to asphalt, concrete, steel and even wood.
• Any weather. Apply from -26°C to 49°C, in rain, or straight into a pothole full of water.
• No tack coat. No pre-coating or priming. Open, pour, compact.
• Traffic-ready. Application is up to five times faster, and it can take traffic immediately.
