The easy to use, safe, high performance spray on waterproofing for wet weather clothing. Adds Durable Water Repellency, revives breathability and maintains internal wicking properties. Your raingear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Tech Wash, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax TX.Direct, after cleaning first with Nikwax Tech Wash. Nikwax TX.Direct Spray-On is easy and quick to apply, and its highly Durable Water Repellency (DWR) develops on air drying. The need for tumble drying is removed, this saves energy and protects more vulnerable, older, garments from heat. Nikwax TX.Direct Spray-On has been specifically designed and optimised for breathable waterproof garments; it leaves a flexible water repellent treatment on individual fibres allowing moisture vapour to pass through, maintaining breathability.The spray-on application allows for direct treatment of areas which require it most (e.g. elbows and seams on jackets) and will not compromise the properties of internal wicking liners.
