Litokol Pixel 3D is a professional silicone sealant for sanitary applications, available here in Nero Antico (12). It is used to seal permanently elastic joints between tiles, stoneware, slabs, and mosaic, and at connections around baths, showers, washbasins, and kitchen countertops. The sealant comes in a 300 ml cartridge and is ready to use without a primer.
Colour & ambiance
Nero Antico (12) is black with a grey undertone, not jet black. This ensures that the connection remains soft rather than sharply defined when used with a dark shower screen.
Product & application
Pixel 3D cures under the influence of humidity and remains elastic thereafter, allowing the joint to absorb movement instead of cracking. The product is intended for floor and wall, indoors and outdoors, even under heavy-duty conditions.
- Ceramic tiles, porcelain stoneware, and large slabs
- Ceramic and glass mosaic
- Terracotta, clinker, and reconstituted stone
- Glass, aluminium, and window frames
- Bathrooms, showers, kitchens, and wet rooms
- Swimming pools, fountains, terraces, balconies, and facades
- Expansion joints, even under heavy loads
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 repairing an existing joint, completely remove the old sealant before reapplying—especially if it has been affected by mould, as applying sealant over a compromised joint solves nothing.
- Suitable for underfloor heating
- Adheres without primer to glass, ceramics, and aluminium
- Not for use on marble, natural stone, or porous materials
- Not in combination with bituminous or plasticizing materials
The number of tile and substrate types is so vast that the manufacturer always recommends a test piece before starting the final joint.
Application
Screw the plastic nozzle onto the cartridge and cut it at an angle to the desired width. Insert the cartridge into the caulking gun and apply the sealant into the joint in one continuous motion, without trapping air. Finish the joint within the open time—after this, 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 trafficable 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 requires longer than a shallow one. Avoid contact with solvents while the sealant is still curing, and store the cartridge cool, dry, and out of direct sunlight in warm weather. Use an opened cartridge within a reasonable time frame.

Frequently asked questions
How many metres 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 about 10 metres; for 10 mm wide and 10 mm deep, it will be about 2 metres.
May I use Pixel 3D on marble or natural stone? No. The technical data sheet explicitly excludes contact with marble and natural stone. For these materials, a neutral-curing sealant is the appropriate choice.
Can I work over an old, compromised sealant joint? No. The old sealant must be completely removed before reapplying. A new layer over a compromised joint will leave the underlying problem unresolved.
When can the shower be used again? The joint can be lightly trafficked after 24 hours and fully used after five days. For a deep joint, it takes longer, as the sealant cures approximately 2 to 3 mm per 24 hours.
