• A ready-to-use, one component sealing material
• Maintains its elasticity for years without any volume loss
• No sagging may occur; resistant to aging and abrasion
• Unaffected by temperature fluctuations (between -40°C and +80°C) and many chemical materials (diluted).

Areas of applications:

•  Developed for use in constant gaps and moveable joints in construction sector
• In the joints of concrete prefabricated construction materials
• In the building materials and blocks, and for filling the joints that are left open as working and settlement allowance
• In buildings, for filling the gaps between details and blocks constructed for decorative and constructive purposes
• In connection areas of the wall and the floor in balconies and terraces
• For filling the joints in the constructions like bridge piers, barrages, tunnels, concrete roads, etc.
•  It should not be used in the materials that are high in plasticized material and not resistant to abrasion and cracking.

Bostik PU Seal is a polyurethane-based, one-component sealing material with excellent waterproofing and adhesion qualities. It is cured with the air humidity and can be used indoors and outdoors.

Preparation of the substrate:

• The application surfaces should be strong, sound, stable, clean, dry and grease- and dust-free.
• Both sides can be taped in order to obtain a smooth filling.
• When necessary, the closed cartridges can be heated in a water vessel up to +10°C and +20°C.
• In coated floor applications (for example, hydrophobic facades), a pre-control is needed for the compatibility.
• In especially acrylic coating materials, some adhesion loss may occur due to the softening material.

Application:

• The tip of the cartridge is cut and a plastic cap is fixed prior to use.
• The tip of the cap is cut according to the width of the surface and fixed to the cartridge gun.
• The cartridge is attached to the gun after the metal lid at the bottom is removed.
• The joints should be filled at one time and without gaps during the application.
• The package of the sausage is cut from one edge and fixed to the suitable gun.
• The cap nut is screwed to the cylinder of the gun afterwards.
• After the joints are filled with PU Seal, the surface is smoothened with a spatula or a wet sponge immediately.
• The adhesive tape should be removed afterwards.
• The opened packages should be consumed as quickly as possible.
• The application is recommended at between -10°C and +40°C.
• Do not apply outdoors in rainy weather.

Cleaning after the application: The contaminated areas and used tools should be cleaned with white spirit or alcohol within 10 minutes. It is cleaned only mechanically after cured.

Coverage: The amount of use varies according to the joint sizes.
