Nano Powered Waterproof. High Performance. Ultimate Wet Blocker, suitable for all materials without a plastic coating, leather, suede & fabric even satin. How does the Woly Wet Blocker work? Once the wet blocker has been sprayed onto the surface, an impregnating layer enfolds every single fibre of leather textile, thus acting like an invisible shield. This prevents the intrusion of moisture, dust & dirt. Drops of water do not seep below the surface, but are simply repelled. Particles of dust & dirt can easily be removed. The tactile quality, the colour & the air & steam permeability of the material remains unchanged. This is ahigh-performance impregnating spray & we consider it the ultimate water-repellent. The treatment will provide comprehensive protection against moisture & dirt as well as water. Suitable for all materials, such as smooth leather, suede, textiles, eg. Nylon, polyester, polyamide, etc. As well as for synthetic & patent leather. Commonly used for footwear, bags, clothing, skiwear & all articles that suffer from permeable damage. Once sprayed, the characteristics of the material are left un-changed. Please note the product packaging can vary from the picture. Made in Germany.
