Do You have an older pools that have some wear on the walls?
If you are replacing a liner in an older above-ground pool, you likely have some surface rust or oxidation on the wall. To prevent this "rust-rot" from transferring to and staining your new vinyl, it is vital to install Protective Wall Foam as a barrier. Additionally, a Poly-Fiber Liner Pad prevents chemical reactions between the soil and the vinyl, stopping "bottom-rot" before it starts and keeping your water where it belongs.
