Tree wound dressing is made primarily from asphalt emulsion — a water-based suspension of asphalt particles that dries into a flexible, waterproof film over the cut surface. Treekote wound dressing uses this asphalt emulsion base as its core material.

The asphalt emulsion base is what makes tree wound dressing perform differently from older petroleum-based wound paints. When it dries, the asphalt emulsion creates a physical barrier that blocks moisture loss, fungal entry, and sap-feeding beetles without forming the rigid, anaerobic seal that gave some earlier formulations a poor reputation. The composition is weather-resistant — it holds in heat, cold, rain, and drought without cracking or washing off.

  • Treekote wound dressing base material: asphalt emulsion (water-based suspension of asphalt particles).
  • When dry, Treekote wound dressing forms a flexible, waterproof film — not a rigid petroleum paint.
  • Treekote wound dressing is available in aerosol (8 oz, 12 oz), brush-top (16 oz), tub (16 oz), and gallon bucket formats — same formulation across all.
  • A 1983 ISA study found Treekote-treated wounds showed higher closure rates and lower decay incidence than untreated controls.
