The Drone Spray-on Hydrophobic Coating (DHC) is a concentrated, eco-friendly, and pH-neutral solution designed for drone-assisted protection of porous surfaces. It forms a durable, breathable, and water-repellent layer that helps prevent water absorption, slows down the regrowth of biological organisms such as algae, fungi, and moss, and enhances the thermal efficiency of buildings.
Ideal for maintaining exterior surfaces in excellent condition, DHC extends the lifespan of materials exposed to weathering and environmental pollution — all while being safe for users, surfaces, and the environment.
£354.55 +VAT
Provides strong water repellency and surface protection
Improves thermal efficiency and prevents weathering damage
Slows down biological growth (algae, fungi, moss, mildew)
Maintains the natural appearance and breathability of the substrate
+ 3 years of lifetime after application
Surfaces: Porous building materials such as concrete, stone, tiles, wood, brick, roofs, and façades
Ideal for: Building maintenance, architectural preservation, energy-efficient surface protection
Use the following dilution ratios when cleaning with a drone
1 part DHC to 10 parts water
Application method: Spray evenly using a low- or high-pressure foamer nozzle or drone system; spray-and-leave — no rinsing required.
Action time / Drying: No rinsing required; the surface becomes water-repellent after drying
Water temperature: Recommended: 5ºC to 30ºC
Coverage: Minimum 0.15 L/m²
All porous surfaces including walls, facades, terraces, roofs, tiles, concrete, and wooden structures.
No. It maintains the natural appearance of the surface while adding a protective hydrophobic layer.
DHC provides at least 3 years of hydrophobic protection, depending on weather exposure and surface condition.
Yes. DHC is compatible with both drone-assisted and manual spraying systems.
Yes, the DHC is pH neutral, water based and free from harsh chemicals.
