CottonProof wash-in or paint-on treatment adds water repellency to cotton, heavyduty canvas and poly-cotton fabrics. It contains a high concentration of active ingredients that make it extremely 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.
Weather proofing
We created some large awnings out of drop-cloth, canvas, and used Nikwax to weather proof and water proof the material. We used the 33oz bottle size. In all we used 5 bottles to weather proof the awnings. this past weekend we had a great deal of rain and there was no leakage. We are pumped and very satisfied with this product. We will use it again and again.
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.
