I am replacing an above ground 18' circulAr pool that was rusting away on the bottom.
I had read that when people are burying above ground pools (which i am NOT doing) they often coat the walls with roof tar to extend the pool life.
While my pool will be sitting on/at the ground level, i do wish to grade some dirt around the bottom edge so that rain and splashes run away from the pool. Also, i was considering coating the bottom rail (since it sits on the ground) and the wall (to about 4" up) with roof tar. Lastly, I was also planning to coat the wall's bottom edge and "fill" the bottom rail as much as possible with roof tar as well (to prevemt any water from pooling inside the rails themselves. The goal is to slow the oxidation/rust process as much as possible. (I do plan to put plastic against the wall for the grading as well, but not underneath the wall as that would just cause the water to pool under the wall instead on soaking into ground.
Has anyone else used roof tar in this manner? Is it a good idea or a bad idea?
