Koch-Chemie × THE FINISHER THE FINISHER "TexLock" Textile Sealant 500ml

THE FINISHER × Koch-Chemie "TexLock" — Textile Sealant against Stains & Resoiling

What does TexLock do in the car? — The breathable textile sealant waterproofs seat covers, carpets, and trunk felt, reduces resoiling, facilitates stain removal, and preserves the original haptics – invisible, breathable, ideal after thorough interior cleaning.

THE FINISHER TexLock Textile Sealant protects heavily used automotive textiles in everyday situations: Liquids bead off, dirt adheres less, the fiber remains grippy and breathable. The formulation cross-links with the fiber structure, without a silicone film or greasy appearance. Perfect after cleaning with InsideUp or specifically with LeatherTexClean – especially on seat surfaces, floor mats, carpets, and trunk felt. Result: more time to blot, less edge formation, significantly easier subsequent care.

• Hydrophobic protection: Liquids bead off, stains penetrate slower; ideal for everyday situations like coffee, soft drinks, wet clothing.
• Invisible & breathable: no "plastic feel," original appearance and grip are maintained; fiber can continue to "breathe."
• Practical in everyday life: facilitates dust/dirt removal, reduces edge formation, and stabilizes cleaning intervals.

Textile Sealant – Function & Fiber Bonding

Textile sealants like THE FINISHER TexLock Textile Sealant work through a thin-film, chemical bond to the fiber structure. Hydrophobic active groups align outwards, water and aqueous stains form droplets instead of soaking in. Because the film is ultra-thin, the fiber remains flexible and breathable – the haptics do not change, the look remains close to factory. This helps against everyday triggers like coffee, rainwater, salt rims from winter moisture, or damp sports gear on the seat.

Application on Seats, Carpet & Trunk

Application is successful when the surface is clean and dry. After pre-treatment with InsideUp or spot treatment with LeatherTexClean, allow textiles to dry completely, then mist THE FINISHER TexLock Textile Sealant evenly in a crosshatch pattern, raise the fibers with a soft brush, and apply another thin layer. Do not oversaturate, mist edge areas cleanly. Allow to dry for 12–24 hours, only then apply stress. Avoid seatbelts, headliners, and airbag zones; apply minimally to Alcantara, always test on an inconspicuous area first.

Durability, Aftercare & Compatibility

Durability depends on use and cleaning. Floor mats and seat bolsters are more heavily used than trunk felt – build up two thin layers there if necessary. For aftercare, clean textiles gently, allow to dry completely, and apply a thin refresh coat when beading diminishes. THE FINISHER TexLock Textile Sealant is invisible, compatible with common interior cleaners, and does not interfere with sensors or seat heating. Please do not seal leather, vinyl, and plastics – LeatherLock or InsideCare/VinylGuard are available for these.

Frequently Asked Questions about THE FINISHER × Koch-Chemie "TexLock" — Textile Sealant

Which surfaces should I use TexLock on?

On automotive textiles such as seat covers, floor mats, carpets, and trunk felt. Not for leather, vinyl, plastics, headliners, or seatbelts.

Does TexLock change the haptics?

No. The sealant remains ultra-thin and breathable – grip and appearance look close to factory, without a rustling or "plastic-like" impression.

How long does TexLock need to dry?

12–24 hours, depending on temperature. Do not stress or wet during this time. Maximum beading performance only after complete drying.

Does TexLock help against salt and winter stains?

It slows down penetration and facilitates stain-free cleaning. Edges can still form but are easier to remove and reoccur less frequently.

How often should I refresh it?

Every 3–6 months, depending on use. Heavily used areas (floor mats, driver's seat) sooner, trunk felt later.
