Nikwax Cotton Proof is a safe, easy waterproofing treatment for cotton, polycotton, and canvas fabrics. It adds water resistance while keeping materials breathable by coating each fiber with a flexible, water-repellent layer. Used in a washing machine, it penetrates deeply and forms a durable finish as it air dries—no tumble drying needed. Ideal for reproofing cotton canvas tents and accessories, it is environmentally friendly, free from harmful chemicals, and gentle on fabrics. Available in 300ml and 1L bottles. Show more
