Gluing
polyethylene tarp can be challenging because its surface is non-porous, making it resistant to adhesives. To successfully glue polyethylene, you need a specialized adhesive designed for polyethylene or a surface treatment process. Here are the steps:
1. **Surface Preparation:** Clean the area to be glued with soap and water, followed by alcohol to remove any grease or oil.
2. **Surface Treatment:** Lightly
sand the surface or use a flame treatment method to increase the surface area for the glue to adhere. Be cautious when using flame treatment; the aim is to slightly modify the surface, not melt it.
3. **Apply Adhesive:** Use an adhesive designed for polyethylene, such as a polyethylene adhesive, epoxy designed for plastics, or a plastic bonding adhesive. Apply according to the manufacturer's instructions. Some adhesives require applying to both surfaces, while others work with a single application.
4. **Clamping:** Press the two surfaces together firmly and allow the adhesive to cure as per the recommended time, which could range from a few hours to 24 hours.
Safety Tips: Work in a well-ventilated area, wear gloves, and follow all safety warnings on the adhesive.
Choosing the right adhesive and properly preparing the surfaces are key to a successful bond. If unsure, testing on a small area before the final application is always a good idea.
