What are the effects of tree sap on the surface of PVC outdoor benches?

Tree sap can have several effects on the surface of PVC outdoor benches, potentially causing aesthetic and functional issues if not addressed promptly. Here’s what you need to know:

1. Sticky Residue: Fresh tree sap creates a sticky layer on PVC surfaces, attracting dirt and debris, which can make the bench look dirty and feel unpleasant to touch.

2. Staining: Over time, sap can penetrate the porous surface of PVC, leading to stubborn stains that are difficult to remove without proper cleaning techniques.

3. Discoloration: Prolonged exposure to tree sap may cause discoloration or yellowing of the PVC material, especially in sunlight, as the sap reacts with UV rays.

4. Surface Damage: If left untreated, hardened sap can scratch or damage the PVC surface when attempting to remove it, compromising the bench’s durability.

To mitigate these effects, clean sap immediately using a mild soap solution or rubbing alcohol. Regular maintenance, such as applying a protective wax coating, can also help prevent sap adhesion. By addressing tree sap promptly, you can extend the lifespan and appearance of your PVC outdoor benches.
