PATTEX Natural Stone, 280 ml

PATTEX Natural Stone is a special elastic adhesive and sealant based on Flextec polymer, designed for applications where high flexibility, strength, and resistance to movement and weather influences are required. This high-modulus sealant particularly excels in the joining and sealing of natural stone, whether for facade joints, transitions between frames and masonry, or stairs and outdoor cladding. It is also suitable for combinations of materials such as wood, aluminum, PVC, bricks, or concrete.

Unlike common silicones, Pattex Natural Stone poses no risk of plasticizer migration and staining, which is crucial for aesthetically sensitive materials such as marble, granite, sandstone, and other stones. The result is a long-lasting clean joint free from stains or discoloration, which remains elastic even after exposure to frost, sun, rain, or movements of construction elements.

The sealant is easy to apply, has excellent adhesion even without a primer, and thanks to its mechanical resistance and flexibility, it is the ideal choice for movable joints and stressed structures both outdoors and indoors.

Main advantages of the product:

• High-modulus elastic sealant with long durability
• Compatible with natural stone – does not cause stains
• Resistant to UV radiation, frost, and moisture
• Suitable for joints between frames and masonry, stairs, cladding
• Flexible even after curing – ideal for movable joints
• Excellent adhesion without the need for a primer
• For indoor and outdoor use

Before use:
Surfaces must be clean, dry, and free of grease. Cut off the top of the cartridge above the thread and screw the nozzle onto the cartridge. The tip of the nozzle must be cut according to the width of the joint/connection.
Insert the cartridge into the application gun. Apply the sealant evenly into the joints.

Application:
Apply the silicone into the joint. Then smooth it out using a spatula or a finger dipped in soapy water.
Do not paint over – due to the sealant's elasticity, it will not hold.

Cleaning:
Immediately remove any adhesive residue with a damp cloth. Cured material can only be removed mechanically.
