Litokol Pixel 3D is a professional silicone sealant for sanitary applications, here in the color Argilla Bruciata (24). It is used to seal permanently elastic joints between tiles, stoneware, slabs, and mosaics, and at connections around baths, showers, sinks, and kitchen countertops. The sealant comes in a 300 ml cartridge and is ready to use without a primer.
Color & atmosphere
Argilla Bruciata (24) is a burnt clay color, reddish-brown and warm. Along terracotta and clinker, it connects to the tile rather than on top of it.
Product & application
Pixel 3D cures under the influence of humidity and then remains elastic, allowing the joint to absorb movement instead of tearing. The product is intended for floors and walls, indoors and outdoors, even under heavy use conditions.
- Ceramic tiles, porcelain stoneware, and large slabs
- Ceramic and glass mosaics
- Terracotta, clinker, and reconstituted stone
- Glass, aluminum, and window frames
- Bathrooms, showers, kitchens, and wet areas
- 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 cannot be painted over.
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 contaminated joint will not solve anything.
- Suitable for underfloor heating
- Adheres without primer to glass, ceramics, and aluminum
- Not for marble, natural stone, or porous materials
- Not in combination with bituminous or plasticizing materials
The variety of tiles and substrates is so vast that the manufacturer always recommends a test piece before starting on the final joint.
Processing
Screw the plastic nozzle onto the cartridge and cut it at an angle to the desired width. Insert the cartridge into the caulk gun and spray the sealant into the joint in one continuous motion, without trapping air. Finish the joint within the open time—after that, the 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 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's about 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 work over an old, contaminated sealant joint? No. The old sealant must be completely removed before reapplying. A new layer over a contaminated joint will leave the underlying problem unresolved.
When can the shower be used again? The joint is lightly loadable after 24 hours and fully loadable after five days. For a deep joint, it takes longer, as the sealant cures approximately 2 to 3 mm per 24 hours.
