Trade Professional Information
- Required Tools: Caulking guns, spatulas, masking tape, cleaning solvents, and personal protective equipment (PPE) including gloves and eye protection.
- Trade-Specific Tips: Ensure surfaces are clean, dry, and free of contaminants before applying the sealant. Use masking tape for clean and precise application. Cut the nozzle at a 45-degree angle for a smooth bead. Smooth the sealant with a damp finger or spatula before it skins over. Allow adequate curing time as specified by the product data sheet. Choose the appropriate type of silicone sealant for the specific application (e.g., acetoxy, neutral, or specialized).
- Common Issues and Solutions: Poor adhesion (ensure proper surface preparation and use a suitable primer if necessary), mould growth (use a mould-resistant silicone sealant in damp areas), and discolouration (choose a sealant that is resistant to UV and chemical exposure). Always consult the product's Safety Data Sheet (SDS) for safety information and handling precautions.
