Instruction:

• Before applying the material, clean the surface from any type of oil, rust, detergents, dirt and other substances that prevent setting. Do not apply to damp surfaces.
• All joints and seams should be thoroughly cleaned with a wire brush or sandblasted before applying the sealant, and any remaining dust should be removed with compressed air.
• To avoid spreading the sealant beyond the joints, masking tape should be used. You can use a sealant gun or a special nozzle for application.
• Place the sealant inside the sealant gun and open the end of the package. Adjust the tip to the width of the joint. Carefully apply the mixture to the joints by pressing the trigger of the sealant gun. After the sealant has hardened, remove the masking tape.
