Pool Plaster Question

[funkeruski]

The temperature hit 102 in South Texas yesterday, so I took my first dip in the pool. While doing that, I noticed about a three inch in diameter circle where the plaster is chipping off. I guess this is known as plaster delamination.

My question is can this be spot repaired or does this mean I need to replaster my pool? I believe my home was built in 1992 or so (I'm not the original owner), and I doubt it has ever been re-surfaced. Just wonderng how much I'm going to need to cut into the kids college fund for this.

It sounds like that particular delamination is known as "spalling" where only about one-sixteenth of an inch of the surface is lost.
A plaster coat is generally about a half of an inch thick. Therefore, you could simply sand the spalling area with sandpaper and make it smooth again.

Unless a lot of areas become delaminated, a few small spalls do not necessarily mean there is a need to re-plaster.

Thanks for the info. What has become detached is indeed a very thin layer of material. Gonna research spalling now.
