Litokol Pixel 3D is a professional sanitary silicone sealant, here in Ardesia (10) color. You can use it to seal permanently elastic joints between tiles, stoneware, slabs and mosaics, and at the connections around baths, showers, washbasins and kitchen countertops. The sealant comes in a 300 ml cartridge and can be used directly, without a primer.
Color & Mood
Ardesia (10) is slate grey, dark and cool. Next to anthracite tiling, the joint disappears; against white, it becomes a deliberate, graphic line.
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 areas
- Swimming pools, fountains, terraces, balconies and facades
- Expansion joints, even under heavy load
Note the limitation: 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 an affected joint will not solve anything.
- Suitable for underfloor heating
- Adheres without primer to glass, ceramics and aluminum
- Not on marble, natural stone or porous materials
- Not in combination with bituminous or plasticizing 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.
Processing
Twist the plastic nozzle onto the cartridge and cut it at an angle to the width you need. Place the cartridge in the caulking gun and inject the sealant into the joint in one continuous motion, without trapping air. Finish the joint within the open time—after that, the outside will set 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
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 cool, dry and out of direct sunlight in hot 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 about 10 meters; for 10 mm wide and 10 mm deep, it will be 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 apply 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 is fully usable after five days. For a deep joint, it takes longer, as the sealant cures approximately 2 to 3 mm per 24 hours.
