A hydrophobic coating is an ultra-thin protective layer applied to a surface that causes water to bead up and roll off rather than spread and absorb. The word hydrophobic comes from the Greek — hydro (water) and phobos (fear). In practical terms, it means surfaces stay cleaner, dry faster, and resist staining, corrosion, and contamination.
How Does it Work?
Hydrophobic coatings work by dramatically reducing the surface energy of the material they're applied to. When water contacts a high surface energy material like untreated glass or concrete, it spreads out and clings. When it contacts a nano-coated surface, the water molecules have nothing to bond to — they form tight droplets and roll away, taking dirt and contaminants with them.
Nanovations coatings use nano-scale silica particles that bond permanently to the substrate at a molecular level. This is not a wax or a film — it becomes part of the surface itself.
What Surfaces Can Be Hydrophobically Coated?
- Glass — shower screens, automotive windscreens, building facades, solar panels
- Concrete and masonry — driveways, retaining walls, building exteriors
- Textiles and fabric — workwear, outdoor furniture, canvas
- Automotive surfaces — paintwork, glass, trim
How is it Different from Traditional Sealers?
Traditional sealers sit on top of the surface and wear away. Nano coatings chemically bond to the substrate, making them far more durable and resistant to UV, abrasion, and cleaning chemicals. A quality nano coating applied correctly will outlast a traditional sealer by years.
How Long Does a Hydrophobic Coating Last?
This depends on the surface, environment, and application quality. Nanovations glass coatings applied to properly prepared surfaces typically last 2–5 years on automotive glass and longer on protected architectural glass. Concrete coatings in sheltered environments can last significantly longer.
Do You Need to Prepare the Surface First?
Yes — always. Surface preparation is critical. Any contamination present when the coating is applied will be sealed in, preventing proper bonding and reducing longevity. For glass surfaces, always use CL-50 Glass Surface Cleaner before applying any coating.
