Nikwax® Cotton Proof is versatile and not just for clothing…

Your customers must be careful to ensure their cotton clothing and gear does not absorb water as it will cause weight gain and take a long time to dry out, impairing breathability and weakening material over time.

Nikwax Cotton Proof is a super easy-to-use waterproofing product that will ensure all cotton, polycotton, and canvas items maintain their durability and breathability.

If an item is fairly new, the customer should proof it with Cotton Proof, which will add a durable water repellent (DWR) treatment to the fibres in order to prevent water absorption.

Should a customer already have a waterproofed item that is now ‘wetting out’, it could be that the item is dirty – and we all know dirt masks water repellency – or, because the DWR has worn away through use. They should first try washing their item with Nikwax Tech Wash® – it removes all dirt and would revive the DWR coating. If cleaning alone is not reviving the water repellency, then the customer needs Cotton Proof: this will replenish the DWR and keep their clothing/gear in prime condition, ensuring high performance in damp or wet weather.

Cotton Proof is so versatile and people may not realise that it can be used on more than just clothing! Canvas tents, bags, bike panniers and other items made from cotton, polycotton or canvas, can all be treated with Cotton Proof. A perfect aftercare item for use during the warmer months when clothing and gear made from this natural fabric are in use. Tell your customers just how super easy it is to use! Plus, as with all Nikwax aftercare, Cotton Proof is water-based, contains no hazardous chemicals or PFCs, so is safe for the user and for the environment.
