Why use Gtechniq I1 Smart Fabric?

I1 Smart Fabric protects all kinds of fabrics from water-based stains. It is breathable and extremely durable, thanks to Gtechniq’s unique scientific formula.

I1 makes ordinary fabrics waterproof and easy to clean. Use it to prevent soaking, swelling or rotting on any fabric. Ideal for use on your cars convertible roof or interior.

Smart Fabric is colour safe. Nano particles that make up I1 Smart Fabric coat each fabric fibre individually, leaving the texture unaffected, allowing the material to breathe. This means stale air will still be able to escape, while repelling water and and oil-based liquids.

Even more hydrophobic than its predecessor, I1 Smart Fabric V2 leaves no remnants of a spillage and moisture simply falls off a coated surface. Laboratory testing reveals that I1 V2 repels water to the highest standard set by the American Association of Textile Chemists and Colorists (AATCC) – ISO 5. And wash tests reveal the product remains at its full performance level after being washed on a 40 degree cycle, and even after five washes still performs better than its predecessor.

On average I1 will last on a car’s interior for between 6 and 12 months - depending how ‘used’ the surface is. On convertible roofs the product will last for up to 2 years.

Application instructions


If using on an interior surface, use I2 TriClean to prepare the surface you are going to treat

For exterior use, use W5 Citrus All Purpose Cleaner neat for dirty surfaces, or dilute at a ratio of 5:1 with water for less soiled areas

Make sure the surface you have cleaned is thoroughly dry (for best results 48 hours in good drying conditions) before applying I1 Smart Fabric. For the optimal impregnation of I1 into your fabric, its moisture content must be below 15% which is significantly dryer than touch dry

Shake well before use and wear gloves

Apply at a temperature of 5°c or above, in a well ventilated area

Use out of direct sunlight

Apply by spraying evenly from a distance of about 15cm ensuring thorough saturation of the surface you are covering

Make sure your application is thorough as once Smart Fabric has dried, you cannot apply a second coat, as the first coat will repel additional product

Avoid over spraying on surrounding substrates, if this happens, wipe immediately with a MF1 ZeroR Microfibre Buff Cloth. Also wipe any excess from the fabric with an MF1

Leave to dry for 24 hours, after this time the full effectiveness of the product will be achieved

Store in a cool, dry place

Use within 12 months of opening
