Litokol Litosil is a one-component silicone sealant in Beige 3, supplied in a 300 ml cartridge. It is used to seal permanently 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
Beige 3 is a warm sandy beige. With travertine-look and cream-colored tiling, it blends with the tile rather than standing out.
Product & application
Litosil cures under the influence of atmospheric moisture and remains elastic, allowing the joint to absorb movement instead of cracking. 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 profile glass
- Wet rooms indoors and outdoor applications
Note the limit: this version cures with acetic acid. For marble and natural stone, choose Litosil Neutro, which is compatible with them according to ISO 16938-1 and does not discolor the joint edges.
Substrate & compatibility
Surfaces must be completely clean, dry, and free of dust, grease, oil, and old paint. Mechanically clean porous surfaces, for example with a wire brush, to remove loose particles. If repairing an existing joint, completely remove the old sealant before reapplying.
- Adheres to most building materials without primer
- For adhesion problems on certain substrates, a specific primer is required
- Not to be used in combination with butyl, EPDM, neoprene, or bituminous and insulating felt
- Not paintable
- Not suitable for full surface bonding
Beforehand, check whether the building materials that come into contact with the sealant are mutually compatible. If further work is to be carried out at the joint location later, check that the released substances do not affect the sealant.
Processing
Twist the plastic nozzle onto the cartridge and cut it diagonally to the desired width. Insert the cartridge into a hand or air pressure gun and inject the sealant into the joint in one continuous motion, without introducing air. Finish the joint within the open time — after that, the outside will skin over.
- 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, first contact the manufacturer's technical service. Store the cartridge in a cool, dry place out of direct sunlight 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 joint size. 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 discolor the joint edges. For these materials, use Litosil Neutro.
Can I apply over an old sealant joint? No. The old sealant must be completely removed before reapplying, otherwise the new layer will not adhere reliably. It also cannot be painted over, so choose the right color immediately.
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 takes longer.
