Spray-On Waterproofing Power

Nikwax TX.Direct Spray-On is a high-performance waterproofing spray that adds water repellency to areas that need protection, without heat activation. It helps restore performance and breathability in jackets with wicking liners. The spray is easy to apply, non-flammable, PFAS-free, and designed for long-lasting protection when used as part of a regular care routine.
Refresh For Everyday Gear

TX.Direct Spray-On 300ml offers a convenient spray-on option to add or renew water repellency and breathability. It prolongs the life of gear by maintaining the coating on outerwear and enhancing performance on damp days. Suitable for coats with wicking liners and other technical fabrics when used as directed.
Down-Proof For Insulated Coats

Down Proof is a wash-in waterproofer designed to add or renew water repellency while maintaining insulation performance in down-filled jackets. This helps keep insulation loft intact, reducing warmth loss in wet conditions and preserving overall comfort during activities in rain or sleet.
Breathable Coat Protection For Animals

Nikwax Rug Proof is formulated for horse rugs, dog coats, and other animal outerwear. It adds durable water repellency while maintaining breathability, helping protect against rain, mud, and damp weather without overheating the animal. A practical choice for protective coverings exposed to frequent wet conditions.
Buying Guide
Key purchase considerations for waterproofing coats include compatibility with fabric types, whether a wash-in or spray-on method is preferred, and how often reproofing should occur based on exposure to rain and washing cycles. Consider the following perspectives:
- Fabric compatibility: Some fabrics, such as Gore-Tex or wool blends, respond best to specific formulations. Always check the product’s guidance for garments with liners or insulation.
- Application method: Wash-in options simplify care by combining cleaning and waterproofing in one cycle, while spray-ons offer targeted reproofing for zones that wear first (elbows, shoulders, cuffs).
- Breathability maintenance: Choose products explicitly designed to preserve or restore breathability, not just water repellency, to prevent overheating and moisture buildup.
- Maintenance routine: Regular cleaning with a dedicated cleaner helps maintain coating performance. Establish a schedule aligned with usage and washing frequency.
- Down and insulation: For down-filled coats, select a product that preserves loft and warmth without adding excessive weight or moisture retention.
- Animal wear considerations: For coats and gear used on pets or horses, look for PFC-free and breathable formulations to safeguard comfort and performance.
