Method of Application

The sealant sausage is placed into the sausage gun and is then moved forward by pulling on the trigger. The material is applied without allowing air to get into the joint.

In wide joints, in order to get the sealant to have contact with both the edges and the base, more than one application with the gun might be required.

The surface on a filled joint should be smoothened and evened with the joint spatula and the masking tapes should immediately be removed from the surface without deforming the shape of the joint.

Storage and Shelf Life

The shelf life of the product is 12 months when it is stored on wooden pallets in a cool, dry and moisture free environment with an ambient temperature between +10°C and +25°C.

Safety Measures

The operator should be wearing proper work attire, goggles, mask and protective gloves appropriate to work and worker safety regulations.

In case of contact with the eyes, rinse with plenty of water before seeking immediate medical attention. Rinse with plenty of water in case of contact with the skin.

During the application smoking should not take place and fires shouldn’t be lit.

For further information on the safe handling of this product please read the Safety Data Sheet (SDS).

Surface Preparation

The surfaces should be clean, smooth, even and dry and weaker particles should be removed from the surface. Avoid application on humid surfaces.

Before application the joints should be thoroughly cleaned with a wire brush, spiral or sandblasting. The joint space should be dusted by blowing air into it.

In order to keep the sealant from spreading around and to make it come out smoothly, a masking tape is used on the upper part of the joint, without the tape reaching the center of the joint. The joint width should not be less than 6 mm. The joint widths should be between 10-30 mm and the depth should be between 6-15 mm. (Approximate ratio: depth/width = 1/2). In order to adjust the aforementioned values, base material (polyethylene fuse etc.) should be used inside the joints.

Application Conditions

Ambient temperature: Between +5 °C and +30 °C.

Joint surfaces of application should be dry and free of moisture.

Make sure that the applied sealant adheres to the inner surfaces of the joints but not to the bases. Varying surfaces and air temperatures may affect service and drying time.

After application, the area should be protected against adverse weather conditions such as direct sunlight, wind, high temperatures (above +50°C), rain and frost.

After application, clean the tools and equipments with an appropriate solvent.

Resistant against water, seawater, diluted alkalis, concrete group and water-based detergents. Not resistant against alcohol, organic acid, concentrated alkali and hydrocarbon fuel.

The final consumption amount might vary depending on application conditions and surface characteristics.
