Litokol Pixel 3D is a professional sanitary silicone sealant, here in the color Terra Fumicata (31). It is used to seal permanently elastic joints between tiles, stoneware, slabs, and mosaics, and at connections around baths, showers, washbasins, and kitchen countertops. The sealant comes in a 300 ml cartridge and is ready to use, without primer.
Color & ambiance
Terra Fumicata (31) is a smoked brownish-grey, dark and muted. Along dark stoneware, it keeps the connection understated.
Product & application
Pixel 3D cures under the influence of humidity and then remains elastic, so that the joint absorbs movement instead of cracking. The product is intended for floor and wall, indoors and outdoors, even under heavy use conditions.
- Ceramic tiles, porcelain stoneware, and large slabs
- Ceramic and glass mosaic
- Terracotta, clinker, and reconstituted stone
- Glass, aluminum, and window frames
- Bathrooms, showers, kitchens, and wet rooms
- Swimming pools, fountains, terraces, balconies, and facades
- Expansion joints, even under heavy load
Observe the limit: do not use Pixel 3D in contact with marble or natural stone. Also avoid contact with bituminous and plasticizing materials such as butyl, EPDM, neoprene, and bituminous or insulating felt. The sealant is not paintable.
Substrate & compatibility
The joint must be clean, dry, and grease-free. If you are repairing an existing joint, completely remove the old sealant before reapplying—especially if it has been affected by mold, as sealing over a damaged joint will not solve anything.
- Suitable for underfloor heating
- Adheres without primer to glass, ceramic, and aluminum
- Not on marble, natural stone, or porous materials
- Not in combination with bituminous or plasticizing materials
The variety of tile types and substrates is so vast that the manufacturer always recommends a test piece before starting the final joint.
Application
Twist the plastic nozzle onto the cartridge and cut it diagonally to the required width. Place the cartridge in the sealant gun and inject the sealant into the joint in one continuous motion, without trapping air. Finish the joint within the open time—after this, the outer surface will close, and the sealant can no longer be smoothed.
- Recommended application temperature between +15 °C and +25 °C
- Skin formation after approximately 15 minutes
- Cures approximately 2 to 3 mm per 24 hours
- Lightly loadable after 24 hours, fully in use after 5 days
- Ensure good ventilation during curing
The curing time increases with the thickness of the joint: a deep joint takes longer than a shallow one. Avoid contact with solvents while the sealant is still curing, and store the cartridge in a cool, dry place out of direct sunlight in warm weather. An opened cartridge should be used up within a reasonable time.

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 will be approximately 2 meters.
Can I use Pixel 3D on marble or natural stone? No. The technical data sheet excludes contact with marble and natural stone. For these materials, a neutral-curing sealant is the appropriate choice.
Can I apply over an old, damaged sealant joint? No. The old sealant must be completely removed before reapplying. A new layer over a damaged joint will leave the underlying problem unresolved.
When can the shower be used again? The joint can be lightly loaded after 24 hours and fully used after five days. For a deep joint, it will take longer, as the sealant cures approximately 2 to 3 mm per 24 hours.
