The Work Process and how to use l shaped rubber seal

An L-shaped rubber seal is commonly used for weatherproofing, insulating, and providing a tight seal between two surfaces. Here’s a streamlined guide on the work process and how to use it:

### Materials Needed:

– L-shaped rubber seal

– Measuring tape

– Scissors or cutter

– Cleaning cloth

– Adhesive (if seal is not self-adhesive)

### Work Process:

1. Measure the Area:

– Use a measuring tape to determine the length of the area where the L-shaped rubber seal will be applied. This could be around doors, windows, or other openings.

2. Cut the Seal:

– Cut the rubber seal to the measured length using scissors or a cutter. Ensure a straight cut for a snug fit.

3. Clean the Surface:

– Wipe down the area with a cleaning cloth to remove dirt, dust, or grease. A clean surface ensures better adhesion.

4. Apply Adhesive (If Required):

– If the L-shaped rubber seal does not come with a self-adhesive backing, apply an adhesive appropriate for rubber and the application surface. Follow the adhesive manufacturer’s instructions for application and curing time.

5. Position the Seal:

– Align the L-shaped rubber seal with the edge of the surface. Ensure the longer side of the L-shape goes along the primary sealing surface and the shorter side fits snugly against the adjacent surface.

6. Press Firmly:

– Press the seal firmly onto the surface, starting at one end and working your way to the other. This ensures even adhesion and prevents air gaps.

7. Inspect the Installation:

– Check for any uneven sections or gaps. Adjust as necessary for a tight fit. It may be helpful to open and close the door/window to verify that the seal works effectively.

### Tips:

– Ensure the surface and seal are dry for the best adhesion.

– Use additional fasteners (like screws or clips) if necessary, especially for heavy-duty applications.
