Pool Plaster Basics Part 1
Since plaster is the exterior shell of your pool and is the part that everyone sees and touches, it is the first place that people usually start to notice cracks, discoloration or other problems. In this 2 part blog series we will cover maintenance techniques to keep it in good condition.
New Plaster Maintenance
Once your pool builder adds the chemicals that are required for the initial balancing of your water brushing the plaster with the nylon-bristle brush will greatly improve the quality of your plaster. It will also prevent the build-up of the normal precipitation of calcium and other minerals in your pool water.
The normal “precipitation” that occurs produces a fine sand on the bottom of your pool; this is common especially in south Louisiana. To remedy this problem, we recommend brushing the pool twice a day for the first seven days (some builders will include this as part of their package).
How your pool water and pH levels affects plaster
Managing your pH levels in a pool is critical to the health of your plaster! Water that is below 7.0 will tend to erode or remove the smooth patina from the plaster surface. Water that is above 8.0 will contribute to the formation of scale and stains.
Calcium is one of the key elements found in both your pool water, and in your plaster. A proper calcium level is 250 ppm. Too much calcium will cause deposits on your plaster while not enough calcium in the plaster may weaken it.
Stay tuned for Part 2 of our series which will cover what to do when you are facing stains or damage from metals in the water as well as what to do about cracks!
