How to Use

Here are the general steps on how to use DOWSIL™ Neutral Plus Silicone Sealant:

1. Surface Preparation: Ensure that the surface to be sealed is clean, dry, and free from any loose debris or contaminants. Clean the surface with a suitable cleaning agent and let it dry completely before applying the sealant.
2. Joint Design: The joint design should follow the recommended standards for the specific application.
3. Masking: If necessary, mask the joint to achieve a neat and clean finish. Apply masking tape to the areas surrounding the joint, leaving a gap of approximately 2mm on either side of the joint.
4. Application: Cut the tip of the sealant cartridge or container to the required size and apply the sealant directly into the joint using a caulking gun. Apply the sealant continuously and uniformly, ensuring that it fills the joint.
5. Tooling: Tool the sealant within 5 to 10 minutes of application, using a suitable tool, such as a spatula, to ensure a smooth and even finish. Do not tool the sealant after the skin has formed, as this may damage the sealant and affect its performance.
6. Curing: Allow the sealant to cure for the recommended time before exposing it to any stress or movement. The curing time may vary depending on the conditions, such as temperature and humidity. Refer to the product datasheet for the recommended curing time.
7. Cleaning: Any excess or uncured sealant can be easily removed using a suitable cleaning agent.

Note: Always follow the manufacturer's instructions and guidelines for the specific application and surface. It is important to wear appropriate personal protective equipment, such as gloves and safety glasses, when using any sealant product.
