Have you come across pools with cracked coping? This pool was built in the 90’s. The white plastic coping had gone through many years of freeze and thaw causing it to bulge & crack.
We opened up each crack using a V blade on a 4″ grinder. The voids behind the coping were filled with a sand mortar slurry mix pumped in to the coping. When that cured we sanded the coping and smoothed the edges of the cracks.
The cracks were then filled with fiberglass netting and resin. When the fiberglass hardened we sanded the cracks again smoothing them out flush with the coping.
After cleaning the coping we coated the coping with a two part epoxy pool paint making the coping look like brand new once again.
The secret to making this repair last is to fill the joint between the coping and the concrete deck. This is a must to prevent water from seeping into the coping again. Open up that joint using the same V blade on a 4″ grinder. You can fill that joint with a self leveling concrete joint filler or a Concrete Mortar Caulking.
This pool was being renovated for a liner replacement and walk in stair repair. The coping repair was just a small part of the overall job. I have added more pictures below..
