The Blanket Safe Spray-On Water-Repellent Treatment for Horse Blankets is water based, that means no odors! The water-repellent wraps around the individual fibers. This treatment is odor-less and safe and will not inhibit the breathability of your blanket materials. This solution does not coat the fabric in non-breathable material and is wax and silicone free! To apply simply wash your blanket and spray the repellent on your clean, wet blanket and air dry! Drying should take 48-72 hours. This drying time is what 'cures' the water repellent product. Once this product is dry it is not harmful to pets or kids! This repellent usually lasts between 9-12 months depending on age of blanket, and wear and tear of blanket. You can keep in mind that blanket safe is not a heavy duty treatment, it is perfect for modern day fabrics, however extremely worn fabrics, or those with a very low denier may not respond as well as blankets with a 1000+ denier. The water-repellent will help increase and maintain the factory applied waterproofing of your horse blanket. This product is made in America.
