Litokol Pixel 3D is a professional silicone sealant for sanitary use, here in the colour Terra di Volterra (22). 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 can be used directly, without a primer.
Colour & ambiance
Terra di Volterra (22) is sand brown with a grey core. A calm choice for beige and greige tiling where the connection should not stand out.
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 floors and walls, 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, aluminium and window frames
- Bathrooms, showers, kitchens and wet areas
- Swimming pools, fountains, terraces, balconies and facades
- Expansion joints, even under heavy load
Note the limit: Do not use Pixel 3D in contact with marble or natural stone. Also avoid contact with bituminous and plasticising 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 mould, because sealing over an affected joint does not solve anything.
- Suitable for underfloor heating
- Adheres without primer to glass, ceramics and aluminium
- Not on marble, natural stone or porous materials
- Not in combination with bituminous or plasticising materials
The number of types of tiles 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 at an angle to the width you need. 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 exterior will close up 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 usable after 5 days
- Ensure good ventilation during curing
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 the sun 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 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 work over an old, affected sealant joint? No. The old sealant must be completely removed before reapplying. A new layer over an affected 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 takes longer, as the sealant cures approximately 2 to 3 mm per 24 hours.
