Why does my plaster have stains?

Some minor discoloration is normal in new plaster. However, actual staining can be caused by the following: the pH is too low; the total alkalinity level is too low; the calcium hardness level is too low; the level of total dissolved solids is too high; high levels of metals in your water.

​Stains can also be caused by debris left in the pool. Usually, metals escaping from this debris create a deposit on the pool plaster and this creates discoloring. Items such as a leaves, if left long enough on the pool floor, can stain your plaster. Call (949) 472-0166 today for more information.

Many times rough plaster must be sanded by hand with a circular sander and fine sand paper. An acid wash may also be necessary, and in many instances, is recommended by pool service professionals when a pool is sanded. Always check with a pool service professional before any attempt at using any pool re-surface chemical, and always follow the direction on the container.

Why are there white, rock-like deposits on my tile?

These are called calcium deposits or calcium build-up.

What is calcium build-up?

Orange County California has some of the hardest water in the country. This hard water has small molecules of calcium. These molecules are left behind at the water line and in other places as the water evaporates. One way to prevent the buildup of the calcium is to brush the water line and spill ways daily along with keeping the PH between 7.4 to 7.8.

How do I get rid of calcium build up?

​A couple ways to remove calcium deposits from your swimming pool tile are by acid washing the pool and using a pumice stone on the calcium deposit or using a bead blaster to remove the deposits. Bead blasters shoot pressurized glass beads at the deposits removing them from your tile. The beads are then vacuumed up by the bead blasting company. If your pool plaster is in good shape, no roughness or stains, you may want to check into bead blasting as an alternative to acid washing. Call (949) 472-0166 today for more information.
