Precautions and Safety Measures

To ensure your safety and obtain optimal results, it is essential to take certain precautions when handling Selleys Silicone Sealant:

1. Always wear protective gloves to prevent skin contact.

2. Handle the tube carefully to avoid punctures or damage.

3. Make sure the work area is well-ventilated to disperse any fumes.

4. Keep the sealant away from flames and ignition sources as it is highly flammable.

5. Store the sealant in a cool and dry place, away from direct sunlight.

Adhering to these precautions will protect you and allow you to work more efficiently with Selleys Silicone Sealant.

Steps to Open Selleys Silicone Sealant

1. Gather the necessary tools: Prepare a sharp utility knife or scissors, a clean cloth, and a clean surface for squeezing out the sealant.

2. Identify the nozzle: The nozzle is located at one end of the tube and serves as an outlet for the sealant. Look for a plastic or metal cap covering the nozzle.

3. Remove the protective cap: Gently twist or pull off the protective cap covering the nozzle. This cap is usually designed to prevent the sealant from drying out.

4. Pierce the nozzle: Take your utility knife or scissors and carefully cut the nozzle tip at a 45-degree angle. Start with a small cut and gradually increase the size if needed. Ensure the opening is large enough for your intended application but not excessively wide.

5. Optimal tube positioning: Before squeezing the sealant, ensure the tube is positioned at a 45-degree angle, with the nozzle facing downward. This angle prevents air from getting trapped inside the tube, allowing for a smooth flow of sealant.

Application Techniques and Tips

Now that you have successfully opened the tube, it's time to apply Selleys Silicone Sealant to your desired surfaces. Here are some essential application techniques and tips to achieve the best results:

1. Surface preparation: Clean the surfaces you intend to seal or bond with a clean cloth and an appropriate cleaner. Remove any dirt, dust, or debris, as these can affect adhesion.

2. Apply consistent pressure: Squeeze the tube gently but firmly to ensure a continuous and consistent flow of sealant. Apply steady pressure to achieve an even bead.

3. Tooling: After applying the sealant, use a putty knife or a specialized tool to smoothen and shape the sealant. This process is called tooling and helps achieve a neat finish.

4. Drying and curing time: Allow the sealant to dry and cure completely as per the manufacturer's instructions. This time may vary depending on environmental factors such as temperature and humidity.

5. Clean up: Remove any excess sealant with a clean cloth or a solvent recommended by the manufacturer. Clean the tools immediately after use to prevent the sealant from hardening.


Selleys Silicone Sealant is a reliable adhesive that can be used for various applications. Understanding how to open and use this sealant properly ensures maximum effectiveness and longevity. Remember to follow safety precautions, open the tube correctly, apply the sealant with technique, and allow for proper drying and curing. By doing so, you will be able to achieve excellent sealing and bonding results using Selleys Silicone Sealant.
