Pool coping creates a barrier around a pool’s edge to protect it from the surrounding surface and keep water from damaging the outer shell.
While the coping prevents water damage, the pool water can sometimes leave calcium deposits behind.
This is the problem for Craig Jackson in Novato, Calif. He asks, “What’s the best way to clean off these hardened deposits?”
Calcium deposits can build up on pool coping like on a glass shower door. This happens when the pH levels in the pool water are off.
Here are three options for cleaning it:
- TSP: When diluted in water, trisodium phosphate is a mild-all around cleaner that removes calcium buildup and oily residue.
- Calcium and lime remover: Use a commercial-grade calcium, lime and rust remover, like ZEP Calcium, Lime and Rust Remover.
- Pumice stone: To clean the buildup without using chemicals, use a pumice stone to scrub the calcium deposits away. It won’t harm pool water and its soft stone surface won’t scratch the pool coping.
Once the calcium build-up is gone, use a clear sealer to prevent it from coming back.
FAQ About Pool Coping
What is the best coping to put around a pool?
Tile, brick, stone, concrete, composite, or even wood are used for pool coping. The most commonly used material is sandstone because of its non-slip properties.
Is pool coping expensive?
What goes between pool coping and concrete/pavers?
Whatever material you choose for your pool coping, the installation is basically the same. The coping is caulked or filled with elastomeric sealant onto the concrete surrounding the pool. An elastomeric sealant allows for some expansion and contraction, so the pool coping won’t crack during temperature shifts.
