CottonProof wash-in or paint-on treatment adds water repellency to cotton, heavy duty canvas and poly-cotton fabrics. It contains a high concentration of active ingredients that make it highly effective on clothing and gear that typically offer minimum protection from the elements. It works great on everything from barn coats and duffel bags to outdoor clothing and tents. Can be diluted with water and sprayed or painted on wet or dry cotton or canvas tents.
USED ON NEW HUNTING COAT
Product easy to use, just followed instructions on bottle.Showed signs of water proofness right out of the dryer.
Wonderful product!
I live on a River Yacht and use this to water proof the upper decks canvas. I follow the directions for the washer and have not had any problems with the product and the results are fantastic. I have recomended it to several other boaters.
A great way to waterproof those winter parkas
Many winter parkas have an exterior of cotton that is fine for snow only, but when the weather warms the snow melts and soaks that fine parka. Nikwax eliminates that problem in a very simple way.
