I drained my pool for a couple of weeks to change the water, clean the
pool surface and replace the pump. Today as I started filling it I
noticed that a 4" chunk of plaster under the skimmer inlet had fallen
away to reveal the gunnite beneath.
Do I need to stop filling the pool below the plaster hole to prevent
water from getting inside, and behind, the plaster? Or is this a
repair I can deal with another time and I can fill the pool up to the
top for now and then just drain the pool below the hole when I'm ready
to fix it?
How hard is it to patch the plaster, is this something I can do myself
or do I need to have a pro do it?
Assuming there's no crack in the shell that's going to leak water, in
which case you could just do a quick and sloppy patch to stop that.
Patching with "cold joints" has from ancient times been nearly
impossible to screed and finish properly, but if you're willing to pay
for diamond polishing tools, you can do a perfect job of it by putting
on too much plaster and polishing off the excess. See my description
It will probably drain itself downb to that level. The plaster is what
holds the water in Concrete (shotcrete, gunite) is not waterproof.
You may be able to fix this yourself but a pro will make it look
right. Some finishes like Florida Gem are proprietary and you probably
can't buy it.
Thanks. From what I've read doing a search, there are actually
plaster mixes I can use to patch it that will set underwater, so I
won't have to drain it at all. This is a pool that is in need of a
replastering in the next year or two anyway, so I'm not too concerned
with how it will look.
