Construction Instructions
1. Cleaning of the Joints Ensure that construction is carried out in relatively dry weather. Prior to application, clean the joints thoroughly. Use a modified joint cleaning machine to grind the walls of the expansion joints. For excess soil at the bottom of the joint, use a homemade iron hook for loosening treatment, followed by using a blower to clean the base. Once the joint is relatively dry, embed the backer material (closed-cell polyethylene board) and apply masking tape on the flat surfaces adjacent to the expansion joint to prevent contamination. (For old joints, it is essential to remove the old sealant from both sides of the joint, especially if different types of sealants are present, as this will affect the bonding of the new product with the cement joint.)
2. Sealing Process For expansion joints ranging from 4mm to 20mm, it is recommended to use a caulking gun for injection. Pour the sealant into an aluminum caulking gun promptly, install the nozzle, cut a suitable hole with a knife, align the nozzle with the expansion joint, press against the top edge of the foam rod, and apply the sealant evenly. For joints wider than 20mm, a caulking gun or crack sealing machine can be used. The entire process of applying the sealant should be completed within the working time, which refers to the period from opening the package, removing the sealant, loading it into the applicator until the completion of application, typically between 60 to 90 minutes. If the weather is hot and humidity is high, the working time may be shortened, so pay attention to your operation time; otherwise, the sealant will become increasingly viscous and difficult to apply. After completion of work, wait for the sealant to cure before removing the masking tape.
3. Requirements for Sealant Depth Given that SV 3350 self-leveling silicone road sealant features ultra-low modulus, excellent UV resistance, and outstanding displacement capability, and has been validated through numerous practical projects, it is recommended that contractors follow these guidelines: Non-self-leveling interface design node diagram Self-leveling interface design node diagram
