Water soluble impregnant that washes into polycotton/cotton/canvas fabric. The impregnation can also be diluted with water and sprayed or brushed onto the fabric, even if the fabric is damp. Due to its water solubility, the fabric is more fire-resistant after processing compared to solvent-based materials. Before processing, it is recommended to wash the product with Tech Wash. A 1 l bottle is enough to saturate a family tent or a large amount of clothes. Note! Cotton, polycotton, etc. are not waterproof materials by themselves, and this treatment can only increase their water *repellency*full waterproofing in prolonged rain will not be achieved. The treatment does, however, speed up the fabrics drying time. Note! The image displays a 300 ml package, but by adding this produc to your cart, you'll get a 1 liter = 1000 ml bottle.
