## Description

NIKWAX COTTON PROOF Wash-in Waterproofing for Cotton Fabric, Polycotton & Canvas Clothing, Tents and Equipment. Adds Water Repellency & Revives Breathability (300ml) : desertcart.co.uk: Sports & Outdoors

Review: Good product - Did the job on a large canvas trailer tent. Easy to apply, we used a car wash sponge for the sides and a sponge mop for the roof to apply it. The product went a long way.
Review: Great product but needed 5x the recommened amount to waterproof my coat - I used this to protect a 3/4 length cotton coat. With my first attempt, following the machine wash instructions, the process failed to waterproof the item. With my second attempt I pre-soaked the coat in a mix of water and the 3 times the recommend amount of product, and then machine washed the coat with another 2 cap fulls of the product. The second attempt was successful and my cotton coat is now waterproof. I would like to give 5 stars, as being able to waterproof something at this price is amazing, but I have to drop 1 star for this problem with the instructions that I encountered.

### ⭐⭐⭐⭐⭐ Great job on canvas tents
*by A***T on 18 September 2025*

Easy to use, waterproofed two large old canvas tents effectively with half left in bottle yet! Diluted and sprayed with vacuum pump. Good value, there hasn't been much rain to test true effectiveness this summer but happy with results so far. Plenty left for further applications.
