Atsko Silicone Waterguard 300g

Atsko Silicone Water-Guard 300g is a high-performance, environmentally-conscious waterproofing spray designed for outerwear, footwear, tents, sleeping bags, suede, and more. Its advanced silicone-based formula delivers maximum repellency in just a single application, saving you time and effort while maintaining the breathability of treated materials. Once cured, it becomes completely odourless and resistant to water and stains, helping to restore and extend the life of your outdoor gear. Safe to use on Gore-Tex®-lined garments, nylon, polyester, fleece, canvas, and coated fabrics, this versatile product is a must-have for anyone looking to keep their gear dry and protected in all conditions.

What truly sets Atsko Silicone Water-Guard apart is its use of CO₂ as a non-flammable propellant—drawn from a waste stream, not fossil fuels—offering a net-zero carbon emission solution. Unlike other aerosol sprays that rely heavily on petroleum-based propellants, this product gives you 300g of pure useable content with only 9g of harmless CO₂ propellant. With lab-proven performance that exceeds ASTM water spray standards and long-lasting results in just one coat, it offers up to six times more value than traditional water-repellent sprays. It's a smarter, safer, and more sustainable choice for waterproofing all your favourite gear.
