Litokol Litosil is a one-component silicone sealant in Black 0, in a 300 ml cartridge. You can use it to permanently seal elastic joints on floors, walls and facades, both indoors and outdoors. The sealant is ready to use and adheres to most building materials without a primer.
Color & Ambiance
Black 0 is black with a grey undertone. Against anthracite tiling, it keeps the line sleek without creating a harsh contrast.
Product & Application
Litosil cures under the influence of air humidity and then remains elastic, so that the joint absorbs movement instead of tearing. The cured sealant is waterproof and highly resistant to weather, aging and UV radiation.
- Expansion joints on floors, walls and facades
- Connection joints in healthcare environments
- Swimming pools in ceramic and porcelain stoneware
- Bonding and insulating glass elements
- Sealing of profile glass
- Wet rooms indoors and outdoor applications
Mind the limit: this version cures with acetic acid. For marble and natural stone, choose Litosil Neutro, which is compatible with these materials according to ISO 16938-1 and will not discolour the joint edges.
Substrate & Compatibility
The surfaces must be completely clean, dry and free of dust, grease, oil and old paint. Porous substrates should be cleaned mechanically, for example with a wire brush, to remove loose particles. If you are repairing an existing joint, completely remove the old sealant before reapplying.
- Adheres to most building materials without primer
- In case of adhesion problems on certain substrates, a specific primer is required
- Not in combination with butyl, EPDM, neoprene or bituminous and insulating felt
- Not paintable
- Not suitable for full surface bonding
Check in advance whether the building materials with which the sealant comes into contact are mutually compatible. If further work is to be carried out later at the location of the joint, check whether the released substances will not affect the sealant.
Application
Screw the plastic nozzle onto the cartridge and cut it diagonally to the desired width. Place the cartridge in a hand or air pressure gun and inject the sealant into the joint in one continuous motion, without trapping air. Finish the joint within the open time – after that, the outside will close.
- Process between +5 °C and +40 °C, ideally between +15 °C and +25 °C
- Skin formation after approximately 15 minutes
- Cures approximately 2 to 3 mm per 24 hours
- Fully loadable after 5 days
- Ensure good ventilation during application and curing
The curing time increases with the thickness of the joint. If the layer needs to be thicker than 15 mm, please contact the manufacturer's technical service first. Store the cartridge in a cool, dry place out of the sun in warm weather, and use an opened cartridge within a reasonable time. Avoid contact with solvents while the sealant is curing.

Frequently Asked Questions
How many meters of joint can I get from one cartridge? That depends on the size of the joint. For a joint 6 mm wide and 5 mm deep, 300 ml will cover approximately 10 meters; for 10 mm wide and 10 mm deep, it's about 2 meters.
Can I use this sealant on marble or natural stone? No. This version cures with acetic acid, which can discolour the joint edges. For those materials, use Litosil Neutro.
Can I work over an old sealant joint? No. The old sealant must be completely removed before reapplying, otherwise the new layer will not adhere reliably. Also, it cannot be painted over, so choose the right color from the start.
When is the joint loadable? The sealant cures approximately 2 to 3 mm per 24 hours and is fully loadable after five days. For a deep joint, this will take longer.
