Gtechniq I1 Smart Fabric makes ordinary fabrics waterproof and easy to clean. Use it to prevent soaking, swelling or rotting on any fabric. From sails, tents and awnings to your car's soft top and interior. Gtechniq I1 Smart Fabric protects all kinds of fabrics from water and oil based stains. It is breathable and extremely durable thanks to unique Gtechniq 3S Smart Surface Science. Unlike regular coatings the nano particles of Gtechniq I1 coat the individual fibers of fabric, leaving the 'breath-ability' and feel of the fabric unaffected. The former means that stale air can still escape but at the same time repelling any water or oil based liquids. Being solvent based ensures a much deeper penetration of the active ingredient giving an I1 treated surface much better durability and overall performance. Typically an I1 treated surface will outlast conventional water repellent coatings by a factor of approximately x5 with durability on soft-tops for example, lasting as much as three years. GTechniq I1 Smart Fabric only takes minutes to apply - simply spray on and walk away! Being alcohol based ensures a much deeper penetration of the active ingredient giving an I1 treated surface much better durability and overall performance. Typically an I1 treated surface will last 5 times longer than conventional water repellent coatings, with the lifespan of the product on soft tops for as long as 3 years.
